It is widely accepted in modern culture that people should eat three meals: breakfast, lunch, and dinner. Nutritionists generally recommend adding two snacks (one in the morning and the other in the afternoon) to help control appetite.

Interestingly, the practice of eating three meals a day is a recent phenomenon. Ancient Romans had only one meal, which they usually had at about four in the afternoon, and they believed it was unhealthy to eat more than once a day. What the Romans ate in the morning and at noon was very light and fast [1]. Later, rules in monasteries affected people’s behavior around food and drink.

During the industrial revolution, breakfast gained importance; workers needed food before work. And dinner didn’t become popular – at least in its current form – until the prevalence of artificial lighting made it possible to eat before dawn and after dusk [2]. The understanding that eating three meals a day is a healthy choice stems from a combination of belief, culture, and early epidemiological studies [3].

There are studies suggesting that having a regular eating habit positively impacts health, regardless of frequency of meals. On the other hand, in a recent and comprehensive study by Kahleova et al., which studied 50,660 adult members of churches in the USA and Canada, it was found that eating one or two meals a day caused lower weight than eating three meals, and also a relatively lower body-mass index (BMI) which got even lower as overnight fasts got longer [4]. The authors state that the positive effects of such a diet are caused by a combination of timing, meal frequency, and overnight fasting, as well as having less frequent meals coupled with precise timing. These results indicate that eating one or two meals is better than eating three or more.

The Prophet’s example

The Prophet Muhammad’s, peace be upon him, recommendations and behaviors lend support to modern medical studies in the area of nutrition, as in many others. He would eat no more than two meals and ensure that one of the meals should consist of light food (such as dates). The Prophet recommended that dinner be eaten, even if it was only a small meal. “Do not leave dinner, even if it is only a handful of dates, because abandoning it makes one weak” (Sunan Ibn Majah).

He defined dinner as the second and last meal of the day, and that it should be eaten after dusk or immediately after the evening prayer.

The Prophet set so many examples about nutrition. He highlighted the dangers of obesity, stating that “What I fear most about my community are developing a belly, oversleeping and idling.” This was centuries ago; nowadays, obesity is an epidemic raging across the world, and its prevalence has almost doubled in more than 70 countries since 1980. In 2015, a total of 107.7 million children and 603.7 million adults were obese [5]. Seventy-five percent of the world’s population is overweight. Obesity, along with dyslipidemia and hypertension, is one of the major factors in cardiovascular diseases. Studies have shown that exercise, as well as meal timing and frequency, are quite effective in weight control [6].

As for table manners, the Prophet said, “The human does not fill any container that is worse than his stomach,” and, “It is sufficient for the son of Adam to eat what will support his back.” Throughout his 63-year-long life, the Prophet never left the table on a full stomach or ate before getting hungry; he recommended that food should not be swallowed without chewing, a practice he maintained. By refusing to sit at tables where there were several types of food, our Prophet was occasionally unable to find anything to eat. There is also no information that our Prophet ever had lunch.

The Prophet’s insistence on fewer meals looks very wise. Not only does eating fewer meals lead to lower incidences of obesity; if it includes a reduction in carbohydrate intake, it can also lead to decreases in total and LDL (bad) cholesterol levels [7]. Considering meal frequency and timing, it is crucial which meals are maintained. In general, breakfast-eaters tend to run a lower risk of weight gain than non-breakfast-eaters – and a significantly lower risk of heart disease [4].

Current studies indicate that food content has as much impact on blood lipids and insulin as meal frequency. Although we cannot fully explain the effects of a single factor on physical health, we are pretty much sure that meal frequencies are closely related to meal timing and which kind of foods are eaten.

The Prophet’s main requirement of food was that it should be lawful and clean, as well as beneficial for the body. His two meals consisted of breakfast and dinner, as is recommended by modern medicine. In a nutshell, the amount of intake and eating etiquette recommended by our Prophet is allocating “one third of the stomach for food, one-third for drink, and one-third for air” (Tirmidhi, Zuhd, 47) and completing meals without getting full. Increasingly, science suggests this may have been good advice!

Like all omnivorous foods, peppers – both hot and sweet – have been created in unique, wise ways to make them appealing to eat and to help reproduce.

Plants and their fruits are sustenance for herbivores, including humans. They are often brightly colored – be it red, orange, yellow, purple, or green, inviting us to a delicious food. But not all plants are meant to be eaten. Indeed, some plants are designed to be unappetizing, either through look or smell; some even have thorns, or sticky, hairy surfaces to deter us from eating them. Another remarkable way that plants are protected against herbivores is the presence of unique chemicals that induce vomiting and pain, or may be toxic.

Many edible plants need to be eaten – it’s how they spread their seeds. Thus, they produce juicy, tasty skin and sweet-smelling aromas. Why, then, are hot peppers different? Though they are nicely colored and juicy, and sweet smelling, they are also hot, and not terribly pleasant for animals to eat.

A recent study at New Mexico State University’s Chile Pepper Institute determined the hottest chili to be the Trinidad Moruga Scorpion Chili. It was chosen from among 125 varieties. Researchers dried and ground it to powder, to isolate its active compound. This way, they were able to determine that the Trinidad Moruga Scorpion reaches about 1.2 million units on the Scoville heat scale. It is so potent that it could induce sweating and tears, and of course puts the mouth on fire.

Figure 1. Molecular mechanism of TRPV receptor activated by capsaicin. TRPVs are located on the surface of nerve cells where they normally respond to changes in temperature by releasing calcium ions. Those ions signal to intracellular machinery to fire nerve action to inform the brain about increased levels of heat. Capsaicin in hot peppers mimics this system, and thus fools brain to think mouth is hot.

What make hot peppers hot?

Animals are equipped with receptors, like TRPV1 in the mouth’s nerve endings, which sense heat. Hot peppers produce a chemical called capsaicin. Capsaicin binds to and activates TRPV1 receptors; thus we feel a heat similar to a burning sensation. In reality, capsaicin does not actually increase the temperature in the mouth, but instead mimics the same process (Figure 1). Since capsaicin mainly dissolves in oil instead of water, drinking water does not help much to get rid of the burning sensation. Cold water provides only temporary aid. However, the drinking of ayran (a Turkish yogurt drink) relieves hotness by removing capsaicin due to the presence of oil in ayran. Interestingly, although mammals have receptors for capsaicin, scientists have recently discovered that birds don’t.

Capsaicin deters mammalian consumption

It is an interesting phenomenon that peppers are hot but need to be eaten to propagate their seeds in different environments, which is done through the droppings of animals. If this is the case, why are hot peppers made unpleasant with capsaicin? To figure out the wisdom behind this contradiction, Joshua Tewksbury performed a study with a group of mice and birds, and found that birds do not distinguish between sweet and hot peppers in their diet. In this study, both mice and birds ate the same amount when fed with food mixed with sweet peppers. However, mice refused to eat foods mixed with hot peppers, while birds happily ate such food. Moreover, analysis of the droppings of birds and mice showed that the seeds passed through the bird’s digestion systems were intact and fully fertile and could germinate, while seeds eaten by mice were either crushed or semi digested so that they were not fertile. Thus, the role of capsaicin in hot peppers is to deter mammals that destroy their seeds while not disturbing birds. This is a great example of ingenious interdependence.

Capsaicin as antifungal agent of peppers

Figure 2. Capsaicin is not only protective against mammals but also fungus contaminations. A) Insects make peppers prone to fungus contamination by causing harm. B) Healthy pepper C) A pepper with fungal contamination. Modified Image from Tewksbury lab.

The infinite wisdom of capsaicin protects peppers against fungus as well. Another study by Tewksbury showed that hot peppers are relatively protected against fungal infections. Tewksbury demonstrated that increased doses of capsaicin inhibit the growth of fungus. This finding is in parallel with lower fungus growth in hot peppers compared to sweet peppers.

But what about insects? How could peppers be protected from insects?

Adaptations against insects

Interestingly, the skins of hot and sweet peppers have different levels of thickness. It has been suggested that this gives an advantage to sweet peppers. Furthermore, this protective layer is made of lignin, which is made of the same material as capsaicin and helps to protect from other threats. This allows peppers to adapt to many different environments. For instance, in the presence of fungal contamination, a pepper might be able to produce more capsaicin and decrease lignin production, or vice versa.

Why do we like to eat hot peppers then?

Humans differ from mammals in their love of hot peppers. There are different explanations why we like to eat hot peppers, despite them being painful. Some experts assert that hot peppers are good for our health by lowering blood pressure, having antimicrobial effects, and increasing salivation thus making a boring diet fun. On the other hand, some experts approach it from the perspective of human emotions and argue that we are actually after the pain produced by hot peppers. In addition, there are some studies suggesting that capsaicin could also suppress other pains.

Hot pepper or capsaicin as pain suppressor

Capsaicin in hot peppers could be used as a pain suppressor, as some studies suggested. A study using mice lacking TRPV1 heat receptors showed that the increased long term activation of TRPV1 by capsaicin could relieve pain following the accumulation of high doses of Ca2+ in the cells. This is accomplished by the suppression of both cellular activities and the transmission of pain through nerves.

Hot peppers are hot and we love them. It seems like we will continue consuming them. As every other art of creation, hot or sweet peppers are likely to have many more levels of wisdom awaiting us to discover.

Don’t most people think that being happy is the most important thing? Isn’t eating one of the most accessible pleasures we have? Why should people limit their culinary pleasures? More outrageous, why should we afflict ourselves by fasting? Why do Islam and Judaism restrict their adherents from the simple pleasure of food each year? For the entire month of Ramadan, Muslims fast from first light until sundown, abstaining from food, drink and marital relations. The Qur’an says, “Oh you who believe! Fasting is prescribed to you as it was prescribed to those before you, that you may (learn) self-restraint” (2:183). Why should the Torah decree for Jews a day of fasting (Leviticus 16:29, 23:27) when for twenty-four hours adult Jews (in good health) are supposed to trouble their bodies by abstaining from eating, drinking and marital relations? Both religions teach us that what we do not eat may be even more important than what we do eat.

All animals eat, but only humans choose not to eat some foods that are both nutritious and tasty. Some people do not eat meat for religious or ethical reasons. Jews and Muslims do not eat pork for religious and spiritual reasons. On fast days such as Yom Kippur—the Day of Atonement and the ninth of Av (a day of mourning like the Shi’a observance of Ashura on the tenth of Muharram)—Jews do not eat or drink anything at all, and abstain from marital relations for twenty-four hours. Fasting results in many different outcomes that help bring us closer to God.

First of all, fasting teaches compassion. It is easy to talk about the world’s problem of hunger, easy to feel sorry that millions of people go to bed hungry each day. But not until one actually feels it in one’s own body does the impact truly hit home. Compassion based on empathy is much stronger and more consistent than compassion based on pity. It is a feeling that leads to action. Fasting is never an end in itself; it has many different outcomes. But none of the other outcomes are of real moral value if compassion is not enlarged and extended through fasting. As the prophet Isaiah said, “The truth is that at the same time you fast, you pursue your own interests and oppress your workers. Your fasting makes you violent, and you quarrel and fight. The kind of fasting I want is this: remove the chains of oppression and the yoke of injustice, and let the oppressed go free. Share your food with the hungry and open your homes to the homeless poor” (Isaiah 58:3-7).

Second, fasting is an exercise in will power. Many people think they can’t fast because it’s too difficult, but actually the discomfort of hunger pangs is relatively minor. A headache, muscle soreness from too much exercise, or a toothache are more severe than the pain temporary hunger produces. I have on one occasion fasted for three days, and found that after the first twenty-four hours the pain decreases slightly, as the stomach becomes numb. The real reason it is challenging to fast is because it so easy to break the fast, since food is almost always in easy reach — all you have to do is take a bite. Thus the key to fasting is the will power to decide again and again not to eat or drink. Our society has increasingly become one of self-indulgence; we lack basic self-discipline. Fasting opposes our increasing “softness” in life; when people exercise their will power to fast, they are affirming their self-control and celebrating mastery over themselves. We need continually to prove to ourselves that we can do it, because we are aware of our frequent failures to be self-disciplined.

The third outcome of fasting is improved physical health. Of course, one twenty-four hour fast will not have any more effect than one day of exercise; only prolonged and regular fasting promotes health. The annual fast on Yom Kippur can, however, awaken us to the importance of how much and how often we eat. For many years, research has shown that when animals are slightly underfed, receiving a balanced diet below the normal quantity for maximum physical health, their life spans were prolonged from 50 to 100 percent. With all the additives placed in food these days, a reduction of total food intake is healthful. More important, since our society has problems with overabundance, fasting provides a good lesson in the virtue of denial. Illnesses caused by overeating are increasing in affluent Western countries, such as the incidence of diabetes. Sixteen million people in the United States have diabetes, according to the U.S. Centers for Disease Control and Prevention.

Diabetes can lead to blindness, kidney disease, heart disease, nerve damage, amputation and sometimes death. The prevalence of the disease is related to high rates of obesity and sedentary lifestyles, which increase the risk of developing the disease. More than half of adults in Los Angeles are overweight, and 60 percent do not get regular exercise. One-fifth of all those who are obese will develop diabetes. Thus going without any food, or even water, for a twenty-four hour period challenges us to think about the benefits of the spiritual doctrine “less is more.”

Fourth in our list of outcomes is that fasting is a positive struggle against our dependencies. We live in a consumer society, and are constantly bombarded by advertising that tells us we must have this or that to be healthy, happy, popular, or wise. By fasting, we assert that we need not be totally reliant on external, material things, even essentials such as food. If our most basic need for food and drink can be suspended for twenty-four hours, how much more may we learn to limit our needs for all non-essentials? Judaism and Islam do not advocate asceticism as an end in itself; in fact, it’s against Jewish and Muslim law to deny ourselves normal physical pleasures. But in our overheated consumer society, it is necessary periodically to turn off the constant pressure to consume, and forcibly remind ourselves that “Man does not live by bread alone” (Deuteronomy 8:3).

Fifth, fasting serves as a penance. Though self-inflicted pain may alleviate some guilt, it is much better to reduce one’s guilt with offsetting acts of righteousness. This is why charity is an important part of Yom Kippur, and the same is true for Muslims during Ramadan. Indeed, Judaism teaches that fasting which doesn’t increase compassion is ignored by God. The concept of fasting as penance helps us to understand that our hunger pains can be beneficial. Contemporary culture desires happiness and comfort above all else. Any pain or suffering is seen as unnecessary, even evil. Though we occasionally hear people echo values from the past that suffering can help one grow, or that an existence unalloyed with grief would lack certain qualities of greatness, many today think that the primary goal in life is to always be happy and free from all discomfort. The satisfaction one derives from the self-induced pain of fasting provides insight into a better possible reaction to the normal, external suffering we will all experience throughout our lives. Taking a pill is not always the best way to alleviate pain, especially if by doing so we allay the symptoms without reaching the root cause.

Sixth, fasting is good for the soul. It often serves as an aid for spiritual experiences. For most people, especially those who have not fasted regularly before, hunger pains are a distraction. People who are not by nature spiritual or emotional individuals will probably find that a one-day fast is insufficient to induce an altered state of consciousness. Those who have fasted regularly on Yom Kippur might like to try a two- to three-day fast (liquids permitted after the first 24 hours). It is best to go about daily activities and devote late evening or early morning to meditation and prayer. Having already fasted for Yom Kippur, one may simply extend the fast another thirty-six to forty-eight hours. We are prohibited to fast prior to Yom Kippur; eating a good meal prior to Yom Kippur Eve is a mitzvah (religious duty), because Judaism, like Islam, opposes excessive asceticism.

The seventh outcome of fasting is the performance of a mitzvah, which is the one fundamental reason for fasting on Yom Kippur. We do carry out mitzvot (religious duties) in order to benefit ourselves, but because our duty as Jews requires us to do them. Fasting is a very personal mitzvah, with primarily personal consequences. Fasting on Yom Kippur is a personal offering to God, from each and every Jew who fasts. For more than 100 generations, Jews have fasted on this day; fasting is part of the Jewish people’s covenant with God. The principal reason to fast is to fulfill God’s commandment, but the outcome of the fast can be any of a half-dozen forms of self-fulfillment. But simply knowing that one has done one’s duty as a faithful Jew is the most basic and primary outcome of all.

Finally, fasting should be combined with the study of Torah (the five books of Moses specifically, or Scriptural texts in general). A medieval text states, “Better to eat a little and study twice as much, for the study of Torah is superior to fasting.” Indeed, the more one studies, the less one needs to fast. Fasting is a very personal, experiential offering. However, though study is also a personal experience, it takes place with a text and/or a teacher. The Divine will is often more readily and truly experienced in study or in spiritual dialogue with others than in solitary meditation.

May our fasting become a first step toward the removal of the chains of self-oppression and narrow-mindedness that enslave us, our neighbors, and our world! May future years of shared fasting by Muslims and Jews lead to a greater understanding and respect through increased acceptance of religious pluralism. May we always be part of those organizations and movements that are fully committed to contributing to world peace, and who are equally committed to respecting both our own religion and our neighbor’s.

Muslim scholar Fethullah Gulen points out that the Abrahamic faiths (Judaism, Christianity, and Islam) and some non-Abrahamic faiths (Hinduism) accept that there is only One source for all religions, and pursue the same goal. Gulen states: “As a Muslim, I accept all Prophets and Books sent to different peoples throughout history, and regard belief in them as an essential principle of being Muslim. A Muslim is a true follower of Abraham, Moses, David, Jesus, and all other Prophets. Not believing in one Prophet or Book means that one is not a Muslim. Thus we acknowledge the oneness and basic unity of religion, which is a symphony of God’s blessings and mercy, and the universality of belief in religion.” Gulen’s description of universal religion as a symphony is an excellent illustration. One cannot have harmony if everyone plays the same notes; and one cannot have symphony if everyone plays the same instruments. Individual conductors and composers are different, but the source of musical creativity is One. According to a hadith narrated by Abu Huraira, Prophet Muhammad said, “The prophets are paternal brothers; their mothers are different, yet their religion is one (because they all have the same father)” (Bukhari, Book 55, Hadith 652).

All the organs functioning in your body have a direct or indirect relationship with me. I can be compared to a kind of “chemical brain.” All metabolic activities are among my duties, including the control of excretions, digestion, and the composition of blood. You would be stupefied if I listed every single function I carry out, but let me tell you this much: biochemists have discovered that I am directly included in more than 80 different activities and related to more than 5,000 chemical reactions taking place in your body. Surprised? But this is only what they’ve learned so far; you do not know me in detail yet. My plain appearance is in contrast with my numerous functions. My size is about one-tenth of the body of a six-month-old fetus; now that you have become a young man, I weigh about one fiftieth of your body weight. Since I am the largest excretory organ in your body, I am firmly strapped with mesentery so you can run, jump, and make other movements without trouble.

Most people see me merely as a bile-producing organ, which happens to be among the simplest of my duties. Let me explain it another way: the heat I produce while working is equal to one-third of the heat your body produces while resting. I have a special circulatory system. Since I am located at a “junction,” the blood coming from the intestines which bear nutrient molecules come to my vein first together with the blood from the spleen, before joining the rest of the bloodstream. It can be compared to an obligatory customs check. The amount of blood I supervise within 24 hours is about 2,000 liters. With every heartbeat, almost 28 percent of the blood being pumped passes through me.

I adjust the level of blood sugar in a very sensitive balance. If you eat desserts or pastries I convert excess sugar into glycogen (animal starch) and store it. If your blood sugar decreases from hunger, I break down glycogen into sugar (glucose) and come to your help so that you do not come to a halt, like a car out of fuel.

I use various protein molecules to synthesize numerous enzymes. I also play a role in blood coagulation, red blood cell production, and storing the iron you need. You know, nothing is wasted in the divine system of nature. So how can I waste anything? When the aged red blood cells die, I help the spleen to break them down and store the iron they contain. My job in fat metabolism is no less important. Thanks to the bile I produce, the fatty food you eat is broken down to smaller molecules to be absorbed in a way similar to detergents remove oily remnants from dishes. Naturally, the fat-soluble vitamins (A, D, E, K) are also absorbed along the process. I store the excess of both these vitamins and fats. Fats are an important fuel particularly for your heart muscles. I excrete an average of 600–700 grams of bile a day. Two minutes after oily foods pass to duodenum the walls of my gallbladder are operated. Through contractions of 2–6 times a minute and a pressure of 25–30 mmHg, the bile is passed to duodenum in a time span of 15 to 90 minutes. What gives bile its yellowish-green color is the substance named bilirubin, which appears with the breaking down of the old red blood cells and disposed of through the bowels.

The Kuppffer cells—as you name them—have the duty of checking out newly produced blood cells one by one in addition to producing antibodies against germs. If any ill-formed blood cells come up, I must detect and destroy them. Otherwise they corrupt your blood. Thanks to the Kuppffer cells, the ill-formed blood cells are destroyed as soon as they are detected.

The average longevity of my cells varies between 150-180 days (220 days maximum). New cells are produced immediately to replace the dying ones and the system works smoothly. In each of these cells there are 1,000-3,000 mitochondria and millions of ribosome. An average of 180 new ribosome are produced every second. Although none of my cells have consciousness or intelligence, thousands of them come together to form little lobes resembling hexagons. The number of these lobes varies between 50,000 to 100,000.

Dear Peter, you intake various toxic substances together with the foods you eat. You don’t even realize that food has been corrupted by bacteria and fungi until its taste changes. Frankly, you should not have lived very long with so much toxic intake; Providence has given me an important duty to protect you from such harm. I capture these toxic compounds released into your bloodstream and neutralize them. The same goes for different medicines you take; I try to neutralize their toxic effects as well. But I have my own limits of tolerance; if I am faced with more toxic substances than I can handle, then I give signals of danger. You wonder how. Well, I shout “help” through red spots in your hands and itchy spots on your skin. You should be more careful about what goes down your throat.

Given that I fulfill various important functions, the littlest failure in me reveals itself as a health problem immediately. Hepatitis is among the common diseases heralding my failure. Excessive increase of bilirubin in your blood causes the white of your eye and your skin to turn yellow. I fear viruses most. Particularly hepatitis B and C viruses destroy my tissue. And alcohol, as you know, is my sworn enemy. I have to exert myself to neutralize even a tiny amount of alcohol. And if the hepatitis virus is added, I become knocked down and contract cirrhosis. It does not happen suddenly, though. Along the process which you know as liver failure I give various signals: skin eruption, digestion problems, sleepiness, and headache after meals, and so on. Since these symptoms are not serious problems, most people ignore these signals I give. Due to my various functions, the lab tests about me are more than a hundred.

Talking about my enemies may have upset you a bit, but it’s not all doom and gloom. After all, I am the organ with the highest capacity to renew itself. Sounds good, right? Otherwise I would have been finished off long ago, so this ability is a real blessing. Let me give you an example: although 90 percent of my cells are destroyed during hepatitis, I can help you survive with the remaining 10 percent if you rest well and control what you eat. If you ignore the disease, it might lead you and me to the grave. Do not ever believe those who take this lightly and say: “This doctor says that a small amount of alcohol is good for health.” Tell it to the marines. Those who say that should visit hospitals first. I’m sorry, Peter, but it really gets on my nerves. If they could only appreciate a work of art like me. Anyway, that’s all for now, please take good care of me.

We are three pairs of large glands that secrete into the mouth through canals and hundreds of very small glands around the throat. The large glands in front of the ear area are called the parotid glands, the glands under the chin are called the submandibular glands, and the ones under the tongue are called the sublingual glands. The parotid glands secrete saliva from the sides of the upper molar teeth, the submandibular glands from the front under the tongue, and the sublingual glands from many openings in the mouth’s base. There are also many more salivary glands in your inner cheeks and lips, and in all other wet spots in your mouth and throat.

Every sugary and starchy food you eat must first interact with our secretion in order to be digested. For this, an enzyme called ptyalin has been placed within us. But for this enzyme to work properly you must chew your food well. Also, you shouldn’t eat anything that is too hot or too cold, or anything that could change the pH (acidity) level of your mouth. Otherwise, this enzyme cannot function correctly. We produce an average of about 1000 milliliters (one liter) of secretion every day; however, we have the capacity to produce 1.5 liters of saliva per day.

Sometimes, the calcium in our enzymes may precipitate and form tartar due to acidic foods. Tartar can sometimes block our secretion canals. When you eat something, saliva production accelerates; but if our secretion canals are blocked by tartar, then the saliva cannot flow. This causes infection accompanied by severe pain and swelling. If our canals aren’t completely blocked, we may swell a little while eating, but we will slowly deflate after a while. Microbes can reproduce easier in accumulated saliva that cannot flow, thus causing severe pain and swelling. Our most frequently seen infection is the one that makes the parotid glands swell up, and is called the “mumps”. Even though it is seen more frequently in children, it may also be observed in adults. The swelling of both of the parotid glands is more frequent in alcoholics.

The thiocyanate ions that have been put in our saliva secretion kill the bacteria in your mouth by breaking them apart. In addition, lysozyme enzymes attack and kill bacteria in your mouth while digesting food remains to prevent the bacteria to feed and reproduce. Hungry bacteria perish more easily. Our infinitely merciful Lord put special proteins called anticorps in our saliva to prevent many diseases that can enter from the mouth before they develop. These anticorps act like special agents that attack and destroy bacteria. If we don’t secrete enough saliva, ulcers will develop in your mouth frequently. If they last long enough, they will get infected and also cause tooth decay.

The control of our secretion is connected to an area that includes the appetite center in the brain stem through the involuntary nervous system. When you smell or taste foods you like, we immediately start secreting saliva as a reflex. When you come across foods that you don’t like, or when you get scared or excited, we slow down saliva production, again reflexively. Suspects in the past used to be given a handful of rice to swallow, with the thought that the real culprit would not be able to swallow them, because the excitement caused by the feeling of guilt would cause his/her mouth to dry.

Diabetes, which is a systemic illness, also has a negative effect on our functioning. Diabetes presents itself with drying of the mouth, along with excessive intake of water, and the frequent need to visit the restroom. One type of rheumatoid arthritis may also cause dry mouth and dry eyes together with joint pain.

As you see, Peter, I’ve briefly explained to you how invaluable and necessary your saliva is. I have not even mentioned our histological and anatomical structure, which resembles a bunch of grapes. I believe you can imagine how each and every one of my gland cells is like a perfect biochemical factory. You wouldn’t relate all these to your mouth being wet for no reason, would you?

We agreed with the other organs to explain the splendid art inherent in us to you; we have patiently waited our turn. Our aim is to remind you to look after yourself so you will continue to live a healthy life and consciously perform your duty of servitude to our Lord Who created us. In addition to your perfections, as human beings you also have certain faults, such as being negligent, deceptive, or forgetting easily. Even if you realize that these are your faults, each bears a distinct wisdom in terms of Creation. If from time to time you can succeed in avoiding this negligence and escaping these experiences by using these shortcomings as a springboard or platform from which to depart, you will be able to reflect and contemplate on the attributes of God with greater admiration.

Indeed, we are just inside the gateway of the body that opens to the outer world, the mouth, an area through which the various substances you eat to stay alive pass through the mechanic process we implement before actually entering the body.

When food first enters the mouth, it is passed through a grinding process that carries out a mechanical breakdown before the chemical breakdown in the stomach and intestines. We teeth are aligned along on your lower and upper jawbone. When you were only a two-month old fetus, the Creator Who is aware of the importance of our tasks began to prepare us, and we were planted, just like a seed sown in the earth, in the crevices in your jawbone, and concealed by your gums. But still, we do not appear immediately after birth, because we may hurt your mother when she is nursing you. Initially, it is necessary for you to be fed with that unique nourishment, your mother’s milk. However, we begin to gradually emerge in the form of tiny stumps while you are still being nursed by your mother, when you are around six or seven months old.

We were created to cut, chew, and grind food of various textures and hardness. The number and mechanical functions of my colleagues, who have names such as incisors (cutting teeth), canines, premolars, and molars vary. The incisors, which are at the front, begin to appear when you are still only 6–8 months old, the ones immediately beside them erupt when you are 8–12 months, the premolars appear when you are 12–16 months, the canines at 16–20 months and second premolars when you are between 20–24 months old.

During this period, we are known as the milk teeth. When you are 6–7 years old, the molars emerge and then when you are 7–8 years old the central incisors appear; between 8 and 9 years of age the lateral incisors, between 9 and 11 the first premolars, between 11 and 13 years the second premolars and the canines, and finally between 12 and 14 years of age the second molars erupt; the third molars, known as the wisdom teeth, usually appear any time between the ages of 17 and 40, although sometimes they do not come through at all. The two front incisors, the canine beside them, and the two premolars and three molars, that is, a total of eight teeth, constitute half of the jaw, but all the teeth work as a team of 32. Sometimes you may hear about humans who perform various experiments regarding our strength. My strongest chewing force was recorded as 1900 Newton. In a demonstration of strength, a human was capable of lifting a weight of 620 lb as high as 7 inches from the ground. Although each of us has different functions and appearances, in terms of where we are situated, in general our anatomic structures are the same. The enamel layer covering me is very hard and shiny. My enamel layer is even stronger than bone. My sections, which cut hard substances you put in your mouths like knives without bending, are in fact covered in enamel. Beneath the enamel surface is a solid, bone-like substance known as dentin, which has a slightly different composition than that of the bone found in other parts of the body. The space in the center of this layer (known as pulp chamber) is filled with blood cells and nerves that nourish me. The section of each of us that is buried beneath the jaw bone is called the root, while the part that is visible and which you brush daily is called the crown. Throughout your lives, everything you put in your mouths, whether it is hard, soft, corrosive or acidic, comes into contact with the crown. Some substances can damage us. Even stone or steel would not be able to withstand the conditions that we teeth are exposed to. Although made of metal, a carpenter’s saw becomes blunt, and even a blacksmith’s grinder looses it effect after a while. But if you take good care of us, we will serve you throughout your entire life. Unfortunately, I have noticed that you do not take care of us at all. You eat sweet things, but you do not clean us, you eat meat, but you do not brush us, you relentlessly use us to crack open nuts, and pour anything you find, whether hot or cold, over us. We can withstand this for now because we are still young, but it is impossible to say how long we can carry on like this. If any of us cracks and bacteria begins to eat away at us, eventually causing us to decay, you will start to complain, but it will be too late.

The Prophet Muhammad, peace be upon him, gave utmost importance to us in his daily life. Whenever the opportunity arose, after eating, before prayer, in the morning when he woke up, the Prophet constantly used a miswak, a cleaning twig, and cleansed us with affection. This is why we sparkled like pearls when he opened his mouth or smiled, and those close to him never sensed an offensive odor from his breath. But many people today do have bad breath because they neglect us. Not only does the smell of bad breath make others uncomfortable, but you are also causing harm to yourselves. After the bacteria that hides in the crevices on and between us makes a hole through the enamel and the bone beneath it, this bacteria then begins to spread to your entire body through the blood cells in the pulp chamber, causing damage to other organs of your body. These bacteria can damage vital organs, such as the heart or the kidneys. At first, you do not notice this, because this occurs over a long period. But these bacteria can gradually destroy many of your organs. When you do finally realize what has happened, it could be too late; your cardiac valves may have stopped working properly, or the filtering function of your kidneys may begin to fail.

If you begin to lose us one by one, initially you will notice the change in the taste of your food, then defects in your speech, and eventually you will notice facial deformities and sunken cheeks. You will have to make dentures at great expense, and only in this way will you be able to restore your appearance; but in terms of function, you will never be able to substitute us with those artificial dentures!

You know that one of the main characteristics that distinguish us from animals is speech. Although the focal point of speech is in the brain, speech actually emerges as a sound or words with the collective assistance of many other organs. These are mainly the lungs, the larynx (voice box), the ears and the tongue; but we too play a big role in the correct pronunciation of many letters and words.

In addition, the mechanoreceptors in us and the cell network in our roots display such perfect precision that when we chew, we do not bite your tongue or cheek. Therefore, you can adjust the force of biting pressure for substances of various textures. If these receptors and cell network did not exist, you would use an identical chewing strategy for eating substances as hard as an apple or as soft as pudding. In which case you could not bite an apple or you would attempt to eat pudding with excessive pressure, causing us to grind together with unnecessary force, even breaking us.

So you can see that nothing has been created without a purpose. Are there any unnecessary details in creation? Of course not! This is impossible; as the eternal wisdom and power of He who created us would never permit something which is deficient or of no purpose..!

Dear Peter! I think this should be sufficient in describing ourselves to you. Naturally, the food we breakdown is not in a condition to be swallowed immediately. Therefore, our neighbors, the salivary glands can explain what happens next…

Irfan Yilmaz is a professor of biology in Dokuz Eylul University, Izmir.

Some people might see me as a rough piece of flesh that wiggles in the mouth. Of course I am not that simple! By looking at my color, some experienced doctors can even diagnose an illness. For example, some well-known symptoms that I show are whitening due to fever, becoming dark brown when you have typhoid, blackening because of a yeast infection, or having a smooth surface because of anemia or lack of niacin (a B-group vitamin).

If you are wondering what my primary duties are, I can say that the first is to help to produce speech, an ability which distinguishes you human beings from animals. For sure this speech production is not only mine. First of all the brain, which is the coordinator of all the organs including me, regulates all my movements in speaking. The other organs that help me form sounds to make words are your teeth, lips, palate, the vocal cords in your throat, and your lungs, which work like an air pump and vibrate those cords. As you see, so many of us work together just to produce your speech.

Other than the speech function, my second major duty is to work as an inspector to taste and process the countless fruits and delicious foods that are given by God. That is how you get an idea about an animal- or plant-based substance that you want to eat. If I did not exist, you might die because of a poisonous plant that you ate out of hunger. Many poisonous substances have a bitter taste. Indeed, I can sense their bad taste the moment I touch them and warn you to spit out the thing in your mouth immediately. When you eat sweet and delicious things, however, I make you remember and thank God, who has given them to you. However, you should be careful about my fondness for taste and control yourself since that is part of a God-given test. My Creator has made a relation between my love of taste and the evil-commanding side of your soul. He has also made me a step for your spiritual development. If you eat and drink too much, which means you are misled by your evil-commanding side and abuse my sense of taste, it will be you who lose. I do what my duty requires and get the taste of everything. But it is your job to use your will power and not to be defeated by your evil-commanding self (nafs). I will never stop you, whether you eat one piece of baklava or ten; I will get the taste of every piece. Do not ever blame me for that!

I have another function that many people are not aware of. My movement causes a negative pressure in the cavity of the mouth. Are you wondering what this negative pressure does? This pressure is needed especially for babies to nurse on their mothers’ breast easily; I help them in the sucking movement. In addition to that, as everybody knows, I have very important functions in chewing and swallowing food. I manipulate the food in your mouth; I soften and moisten it with saliva so that it can be easily swallowed. Also, during swallowing, I move the food back toward the pharynx. I have to be very careful while doing all this, since at my smallest mistake, your teeth might bite and hurt me.

Of course, I can do all this only with the help of my Creator, who has built my anatomy of delicate tissues and cells. Since He never does anything absurd or useless, He has given every organ qualities that are both esthetic and functional. My main body consists of seventeen muscles, eight of which are in pairs. They extend in all directions. Among those muscles are the lipid membrane and some salivary glands. I am the most flexible organ in your body. My many strong muscles enable me to move in lots of directions easily. Those muscles are covered by an epithelial lining which is called the mucous membrane. The small projections on my upper surface are called papillae. These papillae are of several types. They contain receptors which allow you to sense taste and the salivary glands that help me stay wet all the time. The papillae cover as far as an A-shaped line towards my back which makes up a third of my length. Here at my back, there are plenty of salivary glands and the lymphoid tissue, also known as the lingual tonsil. Many germs that enter through your mouth get trapped here. The papillae are named according to their shapes. The filiform papillae (which are long and thin) do not contain taste buds. They only provide a rough surface to move the food easily. The food is moistened by your saliva and crushed by your teeth. Then, with the help of these papillae, I help to shape the food into smaller pieces to make it easier to swallow. The fungiform papillae are mushroom-shaped and scattered among the filiform papillae. They are located at the center of my top surface and they contain taste buds. The circumvallate papillae lie along the A-shaped line which makes up the border of my back. These papillae are larger in size and smaller in number; there are around thirteen of them. Each taste bud on the fungiform papillae has 50 to 75 receptor cells which live for only seven to ten days. When cells die because of hot or acidic foods, new ones are created to make new nerves for the taste buds. Only substances that are dissolved in water can reach the taste receptors. That is why I cannot taste a dry substance that you have taken into your mouth right away; it has to be moistened and softened first. Tasting occurs in the receptor cells of taste, where some analyses are undertaken much more delicately than in a chemistry laboratory. My receptor cells change this chemical stimulus into an electrical stimulus and send it to your brain. This electrical stimulus allows the sense of taste to be perceived.

Among the many kinds of taste, there are four major groups. The taste buds for sweetness are located near my front; the taste buds for saltiness are scattered widely on my surface; the taste buds for bitterness are found at my back; and the taste buds for sourness are on my sides.

My under surface extends between my tip and the floor of your mouth. The mucous membrane that covers this surface is smooth and does not contain papillae. It is purple in color because of the many blood vessels that are inside me and nourish me. By the way, the famous saying that “the tongue does not have a bone” is wrong, since I do have a bone. However, this bone is not located in my front body, which is why I am very flexible and I can say whatever you command me to say. But by my muscles and ligaments I am firmly bound to a U-shaped bone (the hyoid bone) at my root. I am connected to your lower jaw by this bone.

I can have disorders, like every other organ. In fact, many disorders in me are an indication of disorders in the other organs or of a metabolic illness. For example, mouth ulcers can often be seen on me. Some types of mouth ulcer are caused by stress, lack of sleep, or lack of vitamins. Others occur as a result of absorption disorders and as a symptom of Behcet’s syndrome. Some ulcers can last for weeks and they can be very painful. You might suffer from this pain especially when you speak and eat. Diseases such as syphilis and herpes also show themselves as ulcers on me. I might even become cancerous in people who smoke or in those who eat and drink things that are too hot. I sometimes show the symptoms of some metabolic disorders like Down’s Syndrome, the blockage of lymph vessels, glycogenosis and amiloidosis. In these disorders, my muscle mass shows excessive growth due to abnormally deposited glycogen and amyloid.

Dear Peter, until now, your “speechless organs” have talked about themselves in their own tongue. I have always talked, but I have always talked on your behalf, expressing your thoughts and feelings. It is you who are responsible for what I have said, good or bad, since I am bound to your will power. However, today I spoke in my own tongue, and on behalf of our Creator. As is well known, I am an organ that has great potential for both evil and good. It is your duty to control me and use me well. Do not ever forget that I am not a simple mass of muscle, epithelium and nerves. Rather, I am a tool that can be used for both debasing and elevating you. From now on, when you eat an apple, do not swallow it before chewing well; wait till I get the flavor of it very well. In that way, you will have an opportunity to thank God for the food you are given. He is the One who not only gave you that apple, but also me, the organ that can taste it. This is just another amazing thing that makes your life beautiful! By thanking God, you will deepen your worship of Him.

The Creator of the universe, the eternal power of existence who has constant awareness of the activity of every cell in our bodies, has endowed us with many fascinating characteristics in the features of our diet and process of reproduction to enable us to live within the ecological stability and principles of adaptation in our natural environment. I will try to explain some of these features to the best of my ability to give you a brief but significant idea of our unique and amazing creation.

Unlike humans, for whom the total development of the fetus and organs takes around 280 days in the womb, we remain in our mother’s womb for a much shorter period. Following a 34–36 day pregnancy, we are born into the world around the size of a bean, blind and earless. As soon as our mothers give birth to us, we crawl by divine inspiration into a pouch created for our protection and development on our mother’s belly. This pouch is why you define both us and kangaroos among the animal kingdom as marsupials. If we did not climb into the pouch created for us to complete the process of our development, we would not be able to live for the first five months of our lives. We feed by sucking the taps of nourishment, the two teats found within the pouch, for the first five months of our lives without leaving this cozy place of security. After about five months hidden in the pouch, we gradually begin to stick our heads out to learn how to benefit from the other substances God has created for us in the universe. While the younger mothers of our species can give birth every year, the older females only give birth every two years or so.

After the first six months we obtain sustenance from our mothers which contains the bacteria and nutritional weaning supplement our digestive system requires to enable us to make the transition from our mother’s milk to the nutrient which becomes the main provision we depend on for the rest of our lives, eucalyptus leaves. In the eighth month of our lives we become a bit more active and sometimes leave our pouch and ride on our mother’s back but we climb back into our pouch at the first sign of danger. We begin to fend for ourselves and eat the eucalyptus leaves with no help from our mothers a year after our birth. We have our very own eucalyptus tree, sometimes even more than one, and we mark the tree by scratching it with our claws, a kind of signature that defines which of us lives in a certain tree.

It may seem unbelievable to you but we hardly drink any water. This is why our name is said to derive from a word of the Aboriginal language meaning “No drink.” This is mainly due to our diet because our need for water is provided by the eucalyptus leaves we eat, which contain 40–60% water, enough for our bodies. As well as this our digestive system and kidneys have been created with a structure that takes the maximum benefit from the water in eucalyptus leaves and wastes the least possible amount of water. The rate of our metabolism is quite low compared to that of other mammals. This is another factor which greatly reduces the loss of water from our bodies, so we do not have to constantly climb down from the trees we live in to find water.

Those who call us lazy because we sleep a lot, an average of twenty hours a day, unfortunately do not know very much about us. Sleep is necessary for us because fibrous eucalyptus leaves contain very little protein and very few other nutrients. This means they provide us with a low energy diet so we have to optimize our use of this energy. The Creator adapted us so that we sleep for 18–20 hours a day to save energy. So never compare us with those who have the ability or energy to be active but waste their valuable lives in unnecessary actions or idleness.

The high content of aromatic oils and various chemical components of cyanide found in eucalyptus leaves are extremely poisonous to many plant-eating animals but we are an exception. God created us with a unique digestive system because the main ingredient of plants, cellulose, is such a hard substance to digest that we have been created with a caecum, a section of intestine much longer (200cm) than that of other mammals, which acts as a chamber of fermentation. Here the high-cellulose eucalyptus leaves are easily broken down by bacteria and microorganisms living in our caecum, a process which then enables our digestion of the leaves. Some of the harmful oils and components (phenol compounds) in the leaves are refined by our liver, which works in an excellent manner, and then these oils are excreted from our body. The creation of our liver, which acts like a special laboratory that can even transform the most dangerous of poisons into harmless substances, has been referred to by evolutionists ludicrously as “a coincidence” or “unaware mutation.”

There are certain things that we must be wary of in our diet. Out of around six hundred different kinds of leaves we can only eat twenty of them, so from around nine kilos of leaves that we pick every day, we only eat one kilo of the least poisonous ones. We usually choose the fresher leaves, and we detect the amount of poison in each leaf by its odor. This is why our noses are one of the most sensitive organs of our bodies. Sometimes we eat earth to obtain the minerals lacking in our bodies. This sharpens our teeth at the same time.

God Almighty, who created even the smallest detail of the universe perfectly, also created our bodies to meet our every requirement. The All-Knowing Designer of the universe created us with arms and paws so we can easily climb up into the eucalyptus trees we use as our homes, our places of habitat. The soles of our paws that are covered in a thick skin, and our arms and legs, which are equipped with strong muscles, and our hook shaped claws enable us to grip onto the trunk and branches of the tree. We can even sleep while we are hanging from a branch. We have five claws on each of our front paws and two of these claws are placed like the thumbs on your hands. These claws enable us to grip and keep a hold on branches. The second and third claws on our hind paws are joined together to enable a stronger grip. We can grip with all four of our paws just like a human grasps with his or her hand and this helps us to walk up the branches and move around in the tree with great ease.

Our body temperature is perfectly adjusted for outdoor life, and our rainproof fur also protects us from the cold, heat and wind. Our fur changes and adapts every season in length and thickness according to our temperature requirements, Australia is situated in the southern hemisphere, so those of us who live in the south have been created with a longer more bristly fur than those in the north so we can cope with the harsh winter conditions. Our fur has patches of different colors on different parts of our bodies; the darker fur on our backs has been created to absorb and preserve heat while the fur on other parts of our bodies is relatively light in color.

To protect ourselves from strong winds we roll our ears up into a kind of ball and turn our backs, the most insulated part of our bodies towards the wind. The fur on our backs is as protective as that of the animals that live in the Arctic. If you see us curled up on a branch in the winter, don’t worry. Due to our incredible fur coat we are as warm and comfortable as you are in your homes.

Unfortunately, we have been subjected to the never-ending desires and ambitions of humankind. The dingoes, iguanas, and some of the eagles and owls that live in Australia do cause us harm from time to time but the massacre inflicted on us by humans in the nineteenth century was heartless and barbaric. Especially from about 1910 to the 1930s my ancestors were killed for our fur and around 80% of our main source of nutrition was destroyed by cutting down eucalyptus trees. In 1927 our species was subjected to the largest massacre ever. They say that over two and a half million of my brothers and sisters were barbarically killed then. It is reported that there are between two and eight thousand of us living today, and the drop in our population is mainly due to agriculture, urbanization and the destruction of the trees we depend on for our habit and nutrition. There has been a huge increase in deaths among us from contagious diseases and attacks by domestic animals like dogs. In recent years, all praise to our merciful Creator, by the great efforts of some foundations and organizations we have been placed under a conservation order.

This description of our exceptional organs, our behavior we are inspired to adopt, and the many blessings bestowed upon us must have explained to you and enlightened you about certain things. May the greetings of the Almighty, He who created us with a liver to enable us to cope with the poisonous leaves, who enables us to feed our offspring in the security of the pouch on our bellies, who created everything in the universe in total cooperation and harmony with each other, be upon you all…

With this act, the holy Pole meant, “Whenever your son’s spirit prevails over his body, and his heart over his carnal soul, and his intellect over his stomach, and he demands pleasure for the sake of thankfulness, then he can eat delicious things.” (Said Nursi, Nineteenth Gleam, 3rd point.)

I too witnessed a similar incident thirty years ago. With a large group of friends from university I was invited to visit a well-known scholar for whom I had a deep respect. We had the opportunity to attend a dinner with him and among the food served were some delicious cherries. My inner voice said, “If I sit near him, I will not be comfortable enough to eat as many of those cherries as I like.” This was exactly what happened. While I was thinking about how to get a chance to eat more of the cherries, that respected person took one of the cherries, excused himself, and left the table. I still cannot forget how ashamed I was of my thoughts at that time.

As a result of the story of Abdul-Qadir Jilani and my own experience, I started to ponder the activities that function so well in the human body. In medicine, the dynamic balance that entirely governs the body during eating, drinking and digestion is known as homeostasis. The most crucial body fluid in this balance is the blood. All the agents in the blood have a fixed quantity, a fixed measure and are supplied at a constant rate. Blood pressure is stabilized according to the characteristics of each vein. For instance, the average blood pressure of large arteries is about 100 mmHg. If the pressure exceeds this figure, then the result is hypertension. Hypertension can lead to cerebral hemorrhages, paralysis, renal failure, cardiac expansion, cardiac failure and heart attacks, all of which can result in death. As for hypotension, this is when the flow of the blood to the organs, mainly the brain, lessens. Another example of the importance of maintaining balance is that the agents which are responsible for maintaining the concentration of sugar in the blood (glycemia) must be kept at a suitable balance. If the ratio of the blood sugar (glycemia) rises, the person may go into a sugar coma, which is life threatening. However, if the ratio of blood sugar drops, the organs, in particular the brain, are deprived of energy. A hypoglycemia coma (when blood sugar is too low) is even more dangerous for the brain than hyperglycemia (when blood sugar is too high). The concentration of sodium, potassium, chlorine, calcium and fatty acids present in the blood, like sugar, are kept in a dynamic balance. If this concentration is upset, the result may be disease or even death. The Owner of Absolute Will and Infinite Mercy keeps all these in balance thanks to the marvelous mechanisms that He has placed in our bodies. However, we are free as far as actions like eating and drinking are concerned, for we are granted the willpower to choose our actions.

Balance in nourishment

One of the most often discussed medical subjects in recent years is obesity. This is an important health problem that poses a threat to life, and it is related to diabetes, hardening of the arteries (arteriosclerosis), fatty liver, cirrhosis, cardiac failure and heart failure. Apart from using one’s own will power and eating less, doctors have presented other harmless ways that are appropriate to human nature to treat obesity. Being overweight constrains the ability of a person to move (exercise) and this inactivity, in turn, leads to more and more weight gain. God has enabled us to seek nourishment wherever we like, within certain parameters. Naturally, our stomach has a certain capacity and when this capacity is met, we feel full and do not need to eat any more. Yet, even though we feel full and should not eat, as this is what is necessary for the health of our body, we are overcome by our lower self and tend to overeat extravagantly. The problem of obesity seems to be greater in developed countries.

Our Creator has not put any restrictions on the absorption of food into the blood. All the food we eat is taken into the intestines so that the nutrients can pass into the bloodstream. If the dynamic balance (homeostasis) were to be maintained here as well then the body would take as much as it needed and the surplus of food would be evacuated from the body without going into the blood; as a result, obesity would not be a concern, however much a person might eat. But by allowing all the food we eat to pass into the bloodstream, the Absolute Ruler has set a test for us, challenging our wills and warning us about self-control.

Most of the activity during digestion and absorption takes place in the small intestine. Our small intestine is a duct which consists of three parts, namely the duodenum, jejunum and ileum, each having different functions and structures. The length of the intestine is 3–4 meters, and it measures 2–4 centimeters in diameter, varying according to the position in the body. The area of the inner surface of this cylindrical structure is 1,600 cm2 (0.16m2) at its maximum. The inner perimeter of the intestine is not like a flat tube, but rather it has folds, each measuring about 8 millimeters, that stretch over the inner parts of the canal. These folds allow the absorption surface to be increased about threefold. If the inner surface of this structure were flat, the absorption capacity of the small intestine would not be more than 1/600 of its present capacity. The surface of these folds is also not flat, but covered with protrusions called villi that are shaped like a finger; these stretch into the vacuum of the canal by about 1 millimeter. There are between 20 and 40 villi to every square centimeter on the surface of the intestine. These villi allow for there to be a tenfold increase in surface absorption. The surface of the villi has cylindrical cells that are arranged in a single row and these help in absorption. The surface of these cells has extensions that are quite thin and dense, known as microvilli, or epithelial cells. Thanks to these cells with a brush border surface, the absorption surface can increase by about twenty times. Thus, although the surface area of a flat canal of the same size should be approximately 3,300 cm2, thanks to surface folds, villi and bushy edges, the total absorption surface of the small intestine increases to 2 million cm2 (200 m2). Moreover, some research has suggested that the total increase could be even greater (about 1,000 times as much). Normally, 100 grams of fat, 50–100 grams of amino acid, 50–100 grams of iodine, and 7–8 liters of water (consisting mostly of fluids produced within the body) are absorbed by the intestines daily. Furthermore, if one eats or drinks too much, the maximum capacity of the system allows the absorption of several kilograms of carbohydrates, a half to one kilogram of fat, a half to one kilogram of protein and twenty liters of water per day. Our intestines have been created with the capacity to transfer all this food into the bloodstream. If we do not control our eating, this capacity is abused and we can face conditions like obesity.

In this life, one of whose tests is in our body, and in which we are required to strive hard using our willpower, there is no limit to the absorption of foods that have high calories (lipid, carbohydrate, and protein), and this can lead to being overweight, as mentioned above. However, in the absorption of minerals, which are not normally considered as making up the basic components of nourishment, but which are of the utmost importance for the human body (in all the operations of the nerves, muscles, bones and in the balance of all the electrolytes), the rules of dynamic balance occur in our intestines, regardless of our will, by the help and mercy of God. For instance, hemoglobin, which is found in the red blood cells (giving the blood its red color) and is charged with the task of transporting oxygen, contains iron. When there is surplus iron in the body, hemosiderosis occurs, which leads to the destruction of organs such as the liver and the pancreas, or cardiac failure. If there is an iron deficiency, then a person suffers from anemia. It is for this reason that a quite sensitive iron-absorption balance exists in our intestines. Here, it is evident without question that there is Divine Aid and Mercy. The same mechanism works for substances like calcium.

Prophet Muhammad’s, peace be upon him, advice to stop eating before feeling full is a significant measure against obesity, for it eliminates “false” appetite. This has a psychological truth, for the brain responds to the feel of fullness a short time after eating. In fact, we all know by experience that we actually feel full a short while (fifteen–twenty minutes) after we stop eating even if it is a small meal.

To conclude, the Almighty One warns us against extravagance and orders us to use our willpower. At this point, we can see how important a role the blessing of religious belief and the training of the soul and the will play in eating habits. Likewise, the principles of Islam, which is in perfect keeping with human nature, are crucial for the well-being of the community as a whole; charitable alms and fasting, which urge us to help and think about those with less, are obligatory and all kinds of charity and good deeds are encouraged. In Islam extravagance is prevented, not only in eating and drinking.

I have been placed under the cavity of the chest. So that we do not harm each other, the Creator has placed a membrane between me and my neighbors, the heart and lung; I can hear them, but cannot see them. They are further protected by the rib cage, because they are more sensitive than I. Of course that does not mean that I am without protection. Our Lord has placed all of us in the most appropriate way. If I had bones covering me you would have a lot of difficulty eating and drinking and since you could not store what you eat you would need to eat little portions throughout the day. But since I have been placed in the stomach cavity and all the walls are flexible I can easily store all that you eat and drink until you digest them. This means that you are busy with eating only at certain times, allowing you to spend your time with other things.

I look like a kettle and this rather simple-looking shape might make you undermine my skills. It is for this reason that some people speak of me in a rude way, describing me as “a sack-like organ.” To understand how important I am, ask those with stomach ulcers or stomach cancer. God forbid, should I stop functioning; life would become a living hell. Each drop that you drink and each morsel you eat would be like poison and all of the world’s pleasures would vanish.

My walls, which seem like a simple sack, are made of four layers of special tissue. On the outer layer there is a strong tissue, below this are layers of muscle that have been placed vertically and horizontally in a diagonal manner, and under this there is tissue engulfed in a flexible layer and a final lining called the epithelium. Of course, we should not forget the web of blood vessels and nerves that nourish these thick walls. My system of nerves is such a complex system that you would be amazed; it resembles a second brain and it is aware of your whole body without you being aware. When you hurt your foot or you are upset with the slightest thing or laugh because of joy I am affected by this. This nervous system is so sensitive that it affects all my actions and my digestive excretions.

It is through this nervous system that I control my actions and my excretions when the scent of the food comes and you are getting ready to eat, saving you trouble after you have eaten. I can also be easily trained. If you can stick with it you can get me used to a new life after three days. Some stomachs are used to three meals, while others are content with two or one meal a day. My recommendation is that you get me used to two meals a day.

Not a lot of chemical decomposition can occur in the mouth, so all the nourishment you have eaten needs to pass through me before it is digested by the intestines and it becomes part of your body. What happens is that the things you have eaten are broken up mechanically into little pieces by the teeth so that I can accept them. If you hurry and swallow without chewing and do not soften the morsels you tire me out. In addition to this, if the morsels are sharp or too large they can rip the walls of the esophagus and make them bleed. It is best to chew the morsel 30 times, but unfortunately most people do not do this. They send me mouthfuls after having only chewed on it once or twice. They do not realize that they are full and therefore eat too much, disturbing the balance. If you eat slowly I will let the relevant section of the brain know and the feeling of hunger will stop after you have received enough nutrients. In this manner you do not tire me out too much and the nutrients do not go to waste. If you eat too fast I will be full before I get a chance to bring to the surface the molecules that give the sensation of being full and there will be no room for water or air, which allow me to move comfortably.

There are three different types of cells on the mucous layer that lines the inner layer of my walls and which is in contact with the food. One of these excretions is hydrochloric acid (HCl). This acid, which can dissolve even a piece of rock, is used not only to digest all the meat and proteins, but it also kills any bacteria that may come with the food and beverage. Without this acid the pepsinogen enzyme, which breaks down the protein, cannot be activated. The pepsinogen enzyme also synthesizes some other cells. This enzyme cannot function on its own and cannot be excreted if I do not have food in me. It starts to be excreted together with the hydrochloric acid as soon as I start to be filled with food. So how is it that such a strong acid and protein digesting enzyme do not harm my walls? My Creator has provided my lining with a temporary protective layer. The goblet cells that excrete this protective mucous are so sensitive that they excrete a protective liquid that coats it. Every day I sacrifice one and a half million cells to these enzyme and acids. In other words, every three days my inner layer is destroyed by these corrosive enzymes and acids. But thank God, I have been given me such a revitalizing strength that each day this lining is renewed with new cells.

Sometimes, if there is a problem with the excretion of this protective liquid, the acid and enzyme can start to eat at the stomach walls, leading to blood leaking from the arteries that are in the outer layer; this is known as an ulcer, a wound on my walls. Nervousness and tension affect the excretions in me, and therefore people who have a nervous character can develop ulcers more easily than relaxed people. The best thing to do is to live a life where one faces things with patience, neither being too panicky nor too happy, but living in a balanced and mature way. If you try to live in a balanced way then you will maintain order in the stomach and I will be happy.

You cannot move the muscles of my walls like you can your arm or leg muscles. The muscles are commanded and start working according to orders from an autonomous nervous system that you are not even aware of. An important feature of these muscles is that they work slowly, but take a long time to get tired. At the same time, they are very susceptible to growing if you do not take care of yourself properly; if you are not careful I can swell up quickly like a balloon. The evil side of human character has a very close connection with me; so you have to be very careful not to eat and drink too much and consume unlawful food. Otherwise, you might become weak and be easily misled and consequently this makes me nothing more than a waste container and then I become a pest.

Let me tell you some of the things that I do not like. At the top of the list is very hot or very cold food or beverages. Both ruin the enzymes and make them dysfunctional. The best condition for enzymes to work is at your body temperature-that is 36-37 degrees. There are more scientists today than before who think that overly hot or burnt food can cause my cells to turn cancerous. If you heat very cold items in your mouth and then swallow you protect me from getting cold – because if I get cold I contract and my working balance becomes dysfunctional so that I am no longer able to do my job.

When I finish my job of extracting the nutrients and treating them with the enzymes the food takes on a liquid form. When the food has achieved the desired texture I send it through to the intestines that are right below me. In this regard, I am like this transitory worldly life, which is nothing more than a two-door guesthouse-one door for entrance and the other door for exit. I never retain anything in me-I receive from one end and send it out the other. There is no door between myself and the esophagus, so I can take out what is in me if I have to by vomiting. At first, this vomiting reflex might seem a bad thing and you might wonder why there is nothing to prevent this? But let me remind you of something, what if you mistakenly eat something poisonous or something that has gone off, what would you do if you could not vomit? You would have to be taken to hospital so that you do not die of food poisoning and an incision would have to be made in the stomach; I would have to be cleansed out, but by this time you might have died. However, if I feel that something you have eaten is bad I can remove it. But with the gateway that is placed between myself and the intestines I am able to stop the food in the intestines from coming back to ruin the acidic atmosphere in me, as the enzymes in the intestines work under more neutral conditions. My acidic structure would disrupt the intestine’s enzymes. In particular, if the bile salts excreted from the liver and the pancreas enzymes should spill into me the situation would be very chaotic.

Another important piece of advice I can offer to you Peter is not to play any sports when I am full and not to strain yourself. The thick muscle lining on the walls requires a lot of blood to move. After eating a significant amount of blood is withdrawn from other parts of the body and sent to me. If you try to be active in this state you will suffer, as the rest of your organs will not be nourished properly and stress will be put on your heart.

Here’s another secret I’m going to let you in on: the more you fill me up without thinking about whether it is necessary and lawful or not, the more likely it is that you will make spiritual mistakes. Your spiritual well-being and health are inversely proportional to a full stomach. If you make me grow too much all your veins, starting with your heart, will start to gather fat and therefore their functions will slow down. Also your spiritual side will be dulled. Actually it is enough for a person to eat only what they need to survive. Serving your senses of taste and eating within the allowed parameters by remembering the Giver will not only give me peace but will also take you to spiritual horizons. After the food passes through your mouth it does not make much of a difference to me whether it is sweet or salty. Therefore, if you can take charge of your mouth, which acts as a gatekeeper, you can protect yourself from waste and from putting on extra kilos.

Some time ago some people would laugh at my above advice, and they would say, “Good food is the backbone of life and one should feed well.” But now modern medicine and dieticians have started to give the same advice I have been giving for years and they state that eating enough for sustenance is adequate. Most illnesses arise from over-eating; good food may be the backbone of life, but too much of it is a prescription for an early death.

In particular, with the dietary change that you make during the month of Ramadan, I and my team are able to renew ourselves; it is like a fitness camp that prepares us for a new term. This is an important need for us to start the new season. The time for this is approaching. I expect you will use your will power and allow me to rest as commanded. To continue with your life you need me to provide you the nutrients and energy, because without me even your heart could not function. At the root of all biological sustenance there is a need for food intake. Accordingly, I am like a double bladed sword. You should neither neglect me nor indulge me too much. I hope that you will display this balanced outlook and behavior.
