To this day, natural breast milk is still regarded as the best nutritional choice for babies. Recent research on stem cells, genetics, and epigenetics [1] from the last three decades, along with information obtained from studies about childhood and youth and testimonials from organizations that guide health policies worldwide, all support this claim. Modern medicine agrees that breastfeeding is the healthiest, most inexpensive, highest quality, and most appropriate choice for protecting both a mother and baby’s health [2]. The World Health Organization holds breastfeeding as an essential gold standard for the immunological development of a child, starting from the first six months to two years of age [3].

Breastfeeding has many benefits. It strengthens the emotional bond between the mother and her baby. It helps ensure that the baby grows in a healthy manner, by establishing its first feeling of trust; positively effects the baby’s intelligence level; and helps bolster the baby’s immune system.

One of the most studied issues in recent studies is the effect of breast milk on respiratory diseases such as asthma. The effects of breastfeeding on asthma, allergic diseases, and respiratory infections has been a topic of concern for the medical world for at least the last 80 years. Recent studies agree that breast milk has a preventive role against lower respiratory tract infections in infancy (0–2 years). However, there are some complications in these studies. Given the challenges in patient standardization, only food-allergy studies can be standardized. Due to the complexity of the environmental and genetic factors that trigger allergies, it should be considered normal that the effect of breast milk has not yet been fully established to protect against a wide range of allergic diseases, particularly asthma [4].

Asthma is the most common chronic disease in childhood and has a complex structure. It has been on the rise lately, and scientists are scrambling to figure out what is causing this increase as well as the best ways to combat the disease. Asthma can be caused by a wide variety of sources, such as genetics, smoking, microscopic ticks and mites in house dust, allergenics such as grass or pollen, obesity, urban life, air pollution, synthetic nutrition, and imbalance in intestinal flora [5]. In addition, premature birth, low birth weight, a young mother, and early exposure to respiratory infections are factors that increase the risk of asthma [6]. Consequently, it is difficult to independently measure the effect of a single determinant in asthma. In a significant study on 3,963 children in the Netherlands, children were breastfed for at least four months and then followed for up to eight years after birth. The outcomes of the study revealed that breast milk significantly reduced the risk of asthma, independent of other variables. It has been observed that the rate of chronic asthma development decreases as the breastfeeding duration increases [7].

Today, breast milk’s benefits have been proven in protecting babies from respiratory infections both early on and later in life. Breastfeeding provides an emergency line of defense against infectious diseases by helping infants whose immune systems are not yet developed enough to fight infections.

Breastfeeding facilitates a beneficial germ exchange between mothers and babies and helps to develop a strong immune system. Enzymes, hormones, bioactive molecules, and growth factors in breast milk are all extremely vital for babies. These crucial molecules help develop the baby’s immune system by interacting with the proximate elements. Thanks to numerous features in its ingredients, breast milk has a significant role in supporting the baby’s immune system with the development of appropriate microorganisms in the intestine. The strength of the microbial structure in the baby’s intestine depends on the way of delivery, diet, and the variety of foods consumed by the mother. This healthy structure in the intestines is essential for the development of the immune system and for building an increased tolerance to new foods that will be taken orally. In infancy, beneficial microbiota in the intestines starts to develop healthily by breastfeeding in the first four to six months.

A comparative study between the intestinal flora of infants fed with breast milk and formula milk showed that the diversity and density of the desired microorganisms increased in a shorter time and in sufficient amount in the breastfed infants. Today, increased hygiene standards have changed the intestinal flora of infants, especially in Western societies. This, however, has increased the risk of diseases such as asthma [8].

Cytokines (a group of proteins and peptides that allow cells to communicate with each other) in breast milk also serve the development and smooth functioning of the immune system and play an important role in protecting the baby against bacterial infections, wheezing, and allergies. Human milk, especially “first milk,” was found to contain more than 20 cytokines [9]. First milk arrives in the first few hours after birth as a miraculous gift to babies when they are most vulnerable to illnesses and helps to protect against diseases. Ig A antibodies in the first milk also protect against infectious diseases that are commonly experienced in early life, besides obesity, diabetes, and allergic diseases that may come later [10].

Infants fed with ready-made foods have lower amounts and types of bacteria in their intestines than those fed with breast milk, which can consequently increase the risk of eczema and asthma. The issue of delaying foods with high allergy potential, especially when switching to supplementary foods, is still being debated. Some researchers suggest that complementary foods should not be introduced to infants up to 12 months. However, the common opinion is that positive intestinal bacteria that develops with sustained breastfeeding can reduce the risk of allergies to additional foods. Another consensus is that the transition to supplementary foods should not be earlier than six months [11].

As breast milk is the most important food for newborns, mothers should diligently endeavor to complete the suggested period of breastfeeding. Breastfeeding, if continued until the age of two and especially in the first six months, is accepted by international pediatric authorities as the cornerstone of nutrition.

Character formation and breast milk

We are physically and emotionally affected by what we eat or drink. Based on this assumption, it can be argued that breastfeeding might also have an influence on the character formation of babies [12]. Although it has been determined that intelligence and brain development are influenced by the emergence or inhibition of some genetic characters in the baby by epigenetic means, no research based on long-term observations has been conducted. In any case, it would be wise for parents to provide the best food both for themselves and their babies. Inasmuch as they make sure the food is hygienic and natural, they should also be cautious that it is obtained through legitimate means. If, for any reason, the mother’s milk is not enough or is suspended, a milk-mother with necessary qualities may be contracted.

Breastfeeding for two years is prescribed in the Qur’an: “Mothers are to suckle their children for two complete years” (2:233). “We have enjoined on human in respect with his parents: his mother bore him in strain upon strain, and his weaning was in two years” (31:14). Likewise, the Prophet Muhammad, peace be upon him, speaking about his son Ibrahim, who died before he could turn two, said, “He has a milk-mother in Paradise, she will suckle him for his remaining milk, (will complete the term of two years).” (Muslim, Fadail, 63, 2316)

The newborn babies who are fed with infant formulas are becoming sick more frequently and are four times more prone to Sudden Infant Death Syndrome (SIDS) as compared to babies who are breast-fed. The statistical analyses made in the US have shown that, if fed solely by breast milk instead of infant formulas, deaths of at least 9000 infants will be prevented annually. A vitally important feature of the breast milk is that its contents are being dynamically and precisely formulated in direct proportion to the development and as per the needs of the baby, whereas baby foods and formulas do not have such a feature. The taurine amino acid, which is vital for the development of the brain and eye, are abundantly available in the breast milk.

The breast milk, which is recommended to breast-feed for up to two years, is special because of its various aspects: it has a unique chemical composition; the lightly yellow-colored alkaline milk (colostrum) generated right after giving birth is very helpful in protecting the newborns from infections and diseases; mammary (milk) glands operate on a very fine time adjustment and they have a perfect developmental coordination; its prevention against lymphoma, which is a kind of cancer, and its feature of leading cancerous cells to programmed cell death (apoptosis); adjustment of the quantities of minerals and trace elements in milk-generating cells of the mother in accordance with the needs of and in proportion to the growth of the infant; breast-feeding has positive effect on the infant’s IQ development.

Nevertheless, newly conducted researches have been yielding fresh findings and new wisdoms (truths) regarding the breast milk.

The tens of researches conducted on the breast milk till now have all indicated and proved that breast-feeding for a period of 7 to 12 months will positively add to the healthy development of infants’ bodily organs along with their IQ development. There are a number of different factors which contribute to infants’ IQ development and breast-feeding is just an important one among them. The positive contributions of breast-feeding to an infant’s IQ development may be better observed if the infant is raised within a genetically and environmentally healthy medium.

A steady brain development and its positive contribution to an infant’s IQ are related to the molecules such as Docosahexaenoic acid (DHA), Omega-3 fatty acid, Arachidonic acid (AA), Cholesterol and Taurine Amino Acid that are sufficiently found in the breast milk. The breast milk is even more useful for a healthy development of the infant’s social intelligence. According to IQ measurements, the IQs of children who have been breast-fed for periods of 7 to 9 months are found to be 6 points higher than those who have been breast-fed for less than a month.

A mother becomes like an innately secure shelter for the infant during breast-feeding as the secretion of the oxytocin hormone in the mother’s mammary glands is increased during her physical touch to the baby. Though motherly love and compassion are immaterial sentiments, a corporeal hormone is deemed a contributor to the attachment of love between mother and child. Breast milk is also rich in cholecystokinin (CCK), a hormone that acts as somniferous both in the mother and the infant. Thus, breast-fed infants more easily sink into sleep and this favorably contributes to infants’ healthy growth while enabling mothers to take rest. Mothers who are complaining that their children are not easily sinking into sleep can thus try to breast-feed them more frequently and for longer durations.

Breast milk versus allergens

Parallel to babies’ development, their foods also diversify. In order for foods other than breast milk given to the infant for the first time not to cause any sort of allergic reaction, that foodstuff should not be recognized as strange and unfamiliar, and this depends on the degree of sensitivity of that infant’s immune response mechanism. Therefore, whether breast milk has any role in the baby becoming accustomed to potentially allergenic foodstuff is being researched on experimental animals. When lactoglobulin is fed to baby rats, which are highly prone to activating allergic response, together with baby food and with breast milk respectively, the one which is fed as blended with the breast milk has not caused any allergic response while the one which is fed as blended with baby food has caused powerful allergic responses (1). In conclusion, it has been proved that, not the baby foods, but only the breast milk plays an important role in activating an immune response in babies.

It has also been found that, in order to ensure healthy intestinal development in newborn babies, only breast milk should be provided in the early stages after birth. As breast milk forms a protective shield against bacteria and viruses, it eliminates the need for response activation of the immune system during the early stages following birth. Moreover, breast milk also causes growth of Lactobacillus bifidus in the newborn’s intestines which prevent formation of pathogenic bacteria. The oligosaccharides in the breast milk are favorable stimulants for growth of Lactobacillus bifidus and also function as adhesive molecules. A resemblance of lock and key model has been observed between the oligosaccharides of the breast milk and the carbohydrates over the epithelial cells of the intestines. This implies that oligosaccharides of the breast milk function as free-floating receptors over the pathogenic microorganisms of various nature. They prevent adsorption of microbes over epithelial cells of the intestines and hence form a preventive shield against infections.

Oligosaccharides and Necrotizing Enterocolitis (NEC)

The enterecolitis which causes necrosis is a most widespread and fatal intestinal disease, being observed at a rate of 85% in premature babies. Insufficiency of oxygen in epithelial cells of the intestines due to various factors is an important reason for its happening. Insufficiency of oxygen in the intestines deforms the healthy functioning of epithelial cells bringing the medium susceptible for infections due to which the necrosis beginning on mucosa membrane of the intestines may develop down to the depth of the intestines’ innermost layer. Roughly 10-26% of all the infant deaths being observed in the newborn intensive care units of US hospitals are occurring due to Necrotizing Enterocolitis (NEC). This happens very rarely in infants who are breast-fed.

A series of controlled researches have been conducted on baby rats for the purpose of understanding the causes of Necrotizing Enterocolitis (NEC). These baby rats have been sorted out in three separate groups as the ones fed only by breast milk, the ones fed only by baby food and the ones fed by baby food blended with oligosaccharides of breast milk. Animals in all three groups have been exposed to hypoxia (deprivation of adequate oxygen supply) for three consecutive days and their intestinal tissues have been analyzed at the end of the fourth day.

It has been observed that, while symptoms of enterecolitis in intestines of those fed solely by breast milk were the least, and in intestines of the ones fed by baby food blended with oligosaccharides of breast milk were relatively low, but in intestines of those fed only by baby food were extremely high. Medical reports too indicate that Necrotizing Enterocolitis (NEC) is quite rare in breast-fed babies for the oligosaccharides of breast milk prevent formation of this disease. What is amazing is that the oligosaccharides and the complex glycans which play preventive roles against infections are abundantly available in breast milk whereas they are not found in baby foods (2). Although galacto-oligosaccharides which are similar to oligosaccharides of the breast milk are being added into most baby foods, they have not served as preventive against necrotizing enterocolitis. Molecular researches are presently being conducted as to how oligosaccharides of breast milk do function in favor of prevention (2).

It has also been verified by researches that breast-feeding of the infants is having favorable effects on their development of a sense of taste and on likes and dislikes of foods during their childhood years. In a recently conducted research, sour, sweet, mildly sour, salty, bitter and tasteless foods have been given to infants who are being breast-fed, cow milk-fed and baby food-fed and their reactions to these foods have been observed and evaluated. Those who were fed by baby food made a lesser grimace and also preferred more soury and bitter foods (12). When these babies were later offered normal foods, they replied only for the tastes of foods which were similar to the foods they were previously given. Moreover, their facial expressions were lesser and insufficient in terms of differentiation of unpleasant tastes. Basically, the contents of baby foods and nutrients affect children’s future responses to those foods and nutrients and their taste perception ranges (3).

Breast milk conduces to expression of differing genes in infant’s intestines

A reply to discussions on “whether breast milk or readymade baby foods” is given by researchers of the University of Illinois. Of the 22 healthy infants, the researchers fed 12 with breast milk and 10 with readymade baby food for a certain period of time and later analyzed the messenger RNAs (mRNA) in the intestine cells collected from their stools. These mRNAs have been exposed to a number of molecular tests, being later analyzed and compared. The results have disclosed that gene groups different from each other were being activated in intestines of the infants who were being fed by breast milk and baby foods. Genes of intestines that were expressed differently as foods of infants were diversified (4). Moreover, such a different reading, that is, revealing of the genes’ potential was not limited to only a couple of genes. Contents of baby foods and nutrients have been influential on the expression of hundreds of genes. The most striking outcome was that, while the data encoded by the gene that was assigned for revealing response of the genes being exposed to hypoxia (deprivation of adequate oxygen supply) was properly expressed and activated in infants who were fed by breast milk, the data encoded by such genes of the infants who were fed by baby foods was not being described and read. Thus, the probability of developing of enterecolitis (inflammation of the intestines) due to hypoxia (deprivation of adequate oxygen supply) was increasing. It has been understood that preference of feeding the newborns with either breast milk or baby foods plays a significant role in disclosing the data of about 140 genes which stimulate quick development of their intestinal and immune systems. In other words, the genes which are assigned for preservation of the immune system and thus for strengthening the infants against diseases are being easily expressed in the intestines of infants fed by breast milk but not of the ones fed by baby foods (4).

Finally, it is vitally important to feed the infants in hospitals’ newborn units more with breast milk in order to stop the developing of Necrotizing Enterocolitis (NEC). It has been understood that reading and suppression of the genes which are assigned for arrangement of particularly stomach-intestine functions are being arranged depending upon both development and epigenetical mechanisms as, for instance, the environmental factors that influence nutrition. This assertion shows that, while future studies will shed light on how to make ingredients of baby foods more similar to those of breast milk, it will never be substituted by any other nutrient.

Motherhood or maternal recognition is well characterized by associated brain plasticity during both early development and adulthood. Unlike motherhood, paternal-offspring recognition and its related brain plasticity is poorly understood. A group from University of Calgary designed a set of experiments to test whether father mice can recognize their own infants once they’ve reached adulthood. They exposed adult males to their own and genetically unrelated infants for 2 days. The fathers were tested for adult offspring recognition six weeks later. Assay compared the time spent by the fathers with their own and unrelated offsprings. Results showed that although the father mice show similar parenting behavior toward both sets of infants (own and adopted), they only recognize their own pups as adults. Paternal recognition is associated with increased prolactin (a hormone primarily associated to lactation), mediated neurogenesis in the olfactory bulb, and hippocampus, a major component of mammalian brain. These newly generated neurons are important for the formation of socially relevant olfactory memories. Authors also found that the fathers must physically interact with the infants in order to recognize them later. This is confirmed by some control experiments in which fathers are only allowed to see, smell or hear infants through a wire mesh barrier which was not sufficient to induce neurogenesis. One of the socially relevant benefits of paternal recognition of the infants as adults is to avoid incest interactions which cause inbreeding depression.

2- Recently revealed hideous effects of smoking on children

Original Articles: Brion, M.J. et al., Pediatrics 126, e57 (2010) & Kwok, M.K. et al., Pediatrics 126, e46 (2010).

Smoking is bad for our health, but apparently it may also have subtle, yet far-reaching consequences on our children according to two recent studies. The first study reports that mothers who smoke during pregnancy are more likely to have children with psychological problems. A related study presents evidence that babies who develop in the presence of second-hand smoke (from their fathers) may develop weight problems. Dr. Mary-Jo Brion of the University of Bristol tells “Babies exposed to smoke (in the womb) may be prone to rule breaking, such as lying, cheating, bullying, and disobedience in later years” and adds “To some extent it is somewhat surprising that … maternal smoking may also directly impact child behaviors from exposing the fetus to tobacco in utero.” The other study suggests that smoking around expecting mothers (even when the mother herself is not smoking) also affects the child: higher childhood weight appears to be clearly correlated with paternal smoking. “To protect their children, fathers should avoid smoking from conception onward,” says Dr. Mary Schooling of the University of Hong Kong. Furthermore, smoking mothers should not be too surprised to see their children “disobey” when they tell them not to smoke.

3- Exposure to certain wavelengths of light resets the body clock

Original Article: Gooley, J.J. et al., Science Translational Medicine 2, 31ra33 (2010).

With the introduction of high-tech gadgets into our lives, our daily functions have changed drastically. As opposed to old-fashioned bed-time reading of an “actual” book made of paper, we fiddle with our iphones or ipads or notebooks or channel surf on our bedside TVs before going to sleep. A recent study revealed that exposure to certain wavelengths of light, such as those from laptops or TVs, would negatively influence our circadian rhythms (daily rhythmic activity cycle) by resetting our body clocks (e.g., keeping us awake when we should be sleeping). The feeling of sleepiness at night time is triggered by the secretion of a hormone called melatonin. It had been known that exposure of blue light to the eye’s photoreceptor system located in the ganglion cells suppresses the melatonin secretion, therefore stimulating alertness. In their recent work, researchers at Brigham and Women’s Hospital showed that green light exposure of a different cell population on the eyes – cone cells – also resets the body clock by suppressing melatonin secretion. The senior author of the paper, Dr. Steven Lockley, said in an interview that “we need to think about the entire spectrum of light when designing light therapy or lightning designs to boost alertness or induce sleepiness.” The moral of the story is to be more vigilant about our interaction with fancy electronic gadgets at night if we want to have a healthy and relaxing sleep.

4- Poor teachers may impede good students

Original Articles: Taylor, J. et al., Science 328, 512 (2010).

Scholars know that educational environment, including both tasks and the social environment of a classroom, affects children’s achievement just as much as genetic factors. But the teacher plays a main role, because the quality of the educational environment depends on teachers’ performances. A new study underlined the importance of qualified teachers and how they can make a difference in education. The researchers examined the influence of teacher quality by studying 280 identical and 526 fraternal twin pairs in the first and second grades in different Florida schools representing a diverse environment. Identical twins share 100 percent of their genes and fraternal twins share half, and some of the twins were taught by the same teacher but some were in different classes. The researchers used an Oral Reading Fluency test which is based on how many words in a paragraph a child can accurately read in a minute in order to assess the reading skills of children. The researchers recorded the reading scores of students in the beginning of the semester and at the end of the semester, and they followed the students’ improvements during the year. To measure teacher quality, they used the scores of twins’ classmates. By studying twins’ groups, researchers were able to eliminate some other factors such as genetics and socio-economic conditions. According to the findings, the teachers played a role in “moderating” students’ achievements, and they helped the students to grow to their full potential. When teacher quality is very low, genetic variance is constricted, whereas, when teacher quality is very high, genetic variance blooms. As the study’s lead author, Jeanette Taylor, said “Better teachers provide an environment that allows children to reach their potential.”

This article does not claim to provide answers about social traits or morality in general, but simply summarizes the findings of two recent scientific papers that appeared in the journals Science and Nature, describing interesting research on social ethics and moral behavior. The broader implications of the studies are left to the reader to reflect upon.

The article published in Science magazine presents a line of evidence that spending money on others makes us happier. The Nature article comes up with a – perhaps – more surprising finding: preverbal infants can evaluate social actions, and strongly prefer individuals who help others. The results of the two articles thus suggest that not only do we become happier by doing good to others, but we also feel sympathy for other individuals who do so, even before we start talking.

Spending on others makes us happier

In order to investigate the effects of spending money on others, researchers at the University of Vancouver in collaboration with Dr. Michael Norton of Harvard University, first asked a representative group of 632 Americans to rate their general happiness, report their annual income, and estimate how much they spend monthly on: i) bills and expenses, ii) gifts for themselves, iii) gift for others, and iv) charity donations.1 The first and second items of expenditure were averaged to calculate an index of “personal spending,” whereas the third and fourth items were used similarly to deduce a “prosocial spending” index. Data analysis revealed that significantly greater happiness was associated with higher prosocial spending, whereas personal spending was found to be unrelated to happiness.

Second, a group of employees who received a profit-sharing bonus from their companies were put to a similar test. All sixteen employees reported their annual income as well as their general happiness one month before receiving the bonus. Almost two months after the bonus, the same participants reported their general happiness and were asked to estimate how much of their bonus was spent personally or prosocially. The prosocial spending was again found to be the significant predictor of happiness, whilst the income and the bonus both remained insignificant.

Finally, the researchers designed experiments in order to further decipher the correlation between happiness and prosocial spending. To this end, forty-six university students were asked to assess their happiness in the morning, and were given $5 or $20 (a one time stipend) to be spent by 5 p.m. on the same day. Some participants were randomly instructed to spend the money on a bill, an expense, or a gift for themselves (personal spending condition), and the rest were told to spend the money on a gift for someone else, or a donation to charity (prosocial spending condition). After 5 pm, participants were asked to report their general happiness. The participants in the prosocial-spending group reported greater post-stipend happiness, with the effect of stipend size (i.e. $5 or $20) remaining insignificant. This work hence demonstrated that spending money on others promotes more happiness than spending money on oneself-a result that was apparently counterintuitive. Interestingly, when the conditions of the experiments were described to 109 students from the same university and they were asked their opinion on what condition would make them happiest, they were doubly wrong about their prediction: a significant proportion estimated that the $20 on personal spending would cause the highest happiness.

Preverbal infants can evaluate social actions

The second study by a Yale group describes experimental designs where preverbal infants (i.e. infants having not yet learned to speak) were made to watch animated events.2 (The group of infants chosen for the experiments were 6–10 months old.) In the first scheme (see figure, Scheme 1), a character (a red, circular object with eyes) tries to climb a slope, but fails in its first two attempts (A). At the third attempt, another character comes into the picture, either helping the climber by pushing from behind (B), or hindering it by pushing down (C). When the infants were encouraged to choose between the helper and the hinderer, they almost always reached for the helper (only 2 of 26 infants chose the hinderer). Interestingly, when the climber was made to look like an inanimate object as a control, infants did not show any preference for B or C. (Eyes were removed from the climber, and the climber no longer underwent self-propelling motion with the experiment unchanged in all other aspects.) This suggested that the infants did not choose the helper in the first experiment because they simply preferred the action or the shape or the color (further control experiments) of the helper, but instead their choice was purely social: With the eyes removed from the climber, the infants no longer identified the climber as an individual, and did not perceive the events as social interactions.

It is known that infants look at unexpected events for longer times.2 After the experiment described above, the same infants were subjected to a second test where their observation times were measured. In the display (see figure, Scheme 2), the climber sitting atop a hill initially goes back and forth (D) between the helper and the hinderer, and eventually approaches one of the two (E, the climber ends up approaching the helper; F, the climber ends up approaching the hinderer). On average, the infants stared at the display longer when the climber approached the hinderer (which is a surprising action), compared to the climber approaching the helper (which is an unsurprising action). These findings altogether suggest for the first time that the preverbal infants, although themselves unaffected as third parties (hence remaining unbiased), could make judgments about the value of a social act by differentially evaluating those who perform in positive and negative ways.

Social cooperation

Social ethics is not only puzzling for philosophers and sociologists, but also for biologists because social traits are not inherently specific to humans. For instance, altruistic forms of behavior appear to be ubiquitous in nature and occur in creatures from bacteria to mammals. Even within a rapidly growing bacterial culture, a minority of cells are known to commit to reduced growth rates.3 This slow-growing subpopulation can survive an antibiotic encounter to regenerate the colony, providing an insurance policy for the whole population despite their reduced self-benefit. Towards the other end of the spectrum of living beings, vervet monkeys have watchmen that warn fellow monkeys in the presence of predators by attracting attention to themselves,4 increasing their own risk of being attacked. On first reflection, altruism contradicts the selfishness which is the natural outcome of the underlying assumption of Darwinian evolution, survival of the fittest. If only the fittest survive, according to natural selection, how can such magnanimous behavior continue to exist, when individuals who do not maximize their own interest should have been wiped out long before we can come to know them? Biologists are nowadays trying hard to reconcile altruism with selfishness, and altruistic behavior poses yet another challenge for evolutionary biologists (see a recent article in The Fountain for a detailed review5).

Reflections

• Surely We have created human of the best stature as the perfect pattern of creation. (Tin 95:4)
• Those men and women who give alms and lend to God a goodly loan, it will be increased manifold to their credit, and they will have an honorable, generous reward in addition. (Al-Hadid 57:18)
• The Prophet (may peace be upon him) reported that God said, “I created my servants in the right religion but devils made them go astray.” Every child is born with the fitrah (an innate disposition towards virtue, knowledge, and beauty). Everyone is born in the nature of Islam. (Al-Bukhari and Muslim)

An interesting scientific medical study, published in the British Medical Journal (No 6993, 10 June 1995), proved beyond any doubt the benefit of giving a new-born child sugar, in order to reduce the feeling of any painful procedure like heel pricking for a blood sample or before circumcision.

The study, entitled ‘The analgesic (pain killing) effect of sucrose in full term infants: a randomised controlled trial’, was done by Nora Haouari, Christopher Wood, Gillian Griffiths and Malcolm Levene in the post-natal ward in the Leeds General Infirmary in England.

60 healthy infants of gestational age 37-42 weeks and postnatal age of 1-6 days, were randomized to receive 2ml of one of the four solutions: 12.5% sucrose, 25% sucrose, 50% sucrose, and sterile water (control).

The first group of 30 babies received sugar syrup before a routine blood test (heel pricking, which is usually painful) done to detect jaundice. The other 30 babies were given only sterile water as a control group.

Placing 2ml of a 25% or 50% sucrose solution on the tongue before pricking the heel significantly reduced crying time, compared to babies who got water. Also, their heart rate returned to normal more quickly. The stronger sugar solution had the greater effect, crying being reduced further with increasing concentration of sucrose. From which we may conclude that sucrose (sugar) placed on the tongue may be a useful and safe form of analgesia for use with new born infants.

Blass and Hoffmeyer also showed that 12% solution of inter-oral sucrose significantly reduced the duration of crying in new-born babies subjected to heel pricking or circumcision. This study was reported in The Independent newspaper (Friday 9 June 1995) as well as in the British Medical Journal article.

The practice of the Prophet, upon him be peace, is recorded in the collections of his sayings and reports about him, of which the most revered are the two Sahih collections of Bukhari and Muslim:

Abu Burdah reported from Abu Musa, who said: ‘I had a new-born baby; I took him to the Prophet Muhammad, upon him be peace and blessings, who called him Ibrahim. The Prophet chewed a date then he took it and rubbed the inside of the baby’s mouth with it.’

There are many other reported incidents like this one.

The date contains a very high percentage of sugar (70-80%); it has both fructose and glucose which have high calorific values, it is easily and quickly digestible, and very helpful to the brain. The date contains 2.2% protein, vitamin A, vitamins Bl, B2 and nicotruic acid (against Pellagra); it has traces of minerals needed for the body such as potassium, sodium, calcium, iron, manganese, copper. Potassium, of which percentage is very high, has been found to be very effective for cases of haemorrhage, such as the occasions of birth or circumcision.

We may note that the Sunnah also commends dates for the breaking of the fast in Ramadan. Dates should be eaten, if available, before the sunset prayer-this is medically and nutritionally the best way and the Sunnah.

The great worth of dates is also indicated in a famous and beautiful passage of the Qur’an, surah Maryam, verses 25-6:

And shake towards you the trunk of the palm-tree and it will drop on you fresh ripe dates. So eat and drink and be comforted.

This was the prescription of God, the Creator, for the blessed Virgin Mary at the time of the birth of Jesus, the blessed Prophet of God. It was a prescription to make the delivery easy and comfortable.

As in the example we have briefly recorded in this article, we believe further research will confirm for those who still doubt the full worth and truth, the wisdom, of the teachings of Qur’an and Sunnah.

We shall show them our signs on the furthest horizons and within themselves until it becomes clear to them that it is the truth. Is it not sufficient that your Lord is witness over all things? (Fussilat, 41.53)

As the authors of the medical study referred to intend trying new sugary or sweet substances, we shall recommend that they try dates for the newborn for the relief of pain.

Finally, we hope Muslim medical scientists and researchers lake this new discovery on board, and that many more ideas and practices in the teachings of Islam needing investigative research and objective, scientific study will get the attention they deserve.
