Probiotics / Fermented Foods
| ||Gastrointestinal alterations in bacterial flora are common in infants suffering from allergic disease or who will develop allergic disease later. Probiotic supplementation helps normalize and strengthen the lining of the GI tract in infants. Eczema symptoms have been reduced in infants when they were supplemented with probiotics. In addition, probiotic supplementation in mothers for 6 months before and after birth reduced the incidence of eczema in their children by 50%. [Brit J Nutr 2002 Sep; 88 Supp 1: pp. S19-27] Antibiotic use in early infancy has been associated with an increased risk of allergic disease in later childhood, which is in keeping with the understanding that a disturbed GI flora will contribute to an allergic tendency. A family history of atopic disorders like dermatitis further suggests that probiotic supplementation would be wise both pre- and postnatally.|
Fish Oil / Krill
| ||The incidence of preterm delivery was reduced more than 3 fold by the consumption of 15gm (1/2 ounce) of fish (or 500mg of fish oil) per day compared to women who ate none. Since it has been demonstrated that consumption of Omega 3 oil does increase EPA but not DHA in the breast milk of women eating it, using flax seed oil alone to achieve the effect of fish oil, which contains EPA and DHA, may not work to prevent preterm deliveries.

Ginger Root (Zingiber officinalis)
| ||Ginger syrup was used to reduce nausea and vomiting in a controlled study of 26 women during the first trimester of pregnancy. 250mg ginger was used four times daily [Altern Ther Health Med 2002;8(5): pp.89-91]. Although this was the amount used in the study, the recommended dose is 1 gram as needed several times per day, says Varro Tyler, PhD., dean and distinguished professor emeritus at Purdue University in West Lafayette, Indiana. |
Using capsules of ginger root purchased at a health food store will give you the greatest convenience and control over the amount of ginger you are using. There may be a variety of products available from your health food store designed to help control nausea which include ginger. One such product is called Preggie Pops, a lollipop created for this problem. It does, however, contain sugar.
Do not use more than 3-5gm of dried ginger per day during early pregnancy.

| ||Human studies have found an increase in the rate of miscarriages, stillbirths, breech births and low birth weight when given in doses greater than 300mg (an amount equal to three cups of coffee) per day. Pregnant women are also three times slower to metabolize caffeine than nonpregnant women. Therefore, it is recommended that pregnant women consume less than this amount - in fact some doctors say that coffee should be completely avoided during pregnancy and breast feeding.|
Fetuses and newborns cannot metabolize caffeine in their livers, so it remains in their bodies for up to four days, stimulating their nervous system the entire time, causing irritability and sleeping difficulty. In addition, the use of large amounts of caffeine by a mother during pregnancy may cause problems with the heart rhythm of the fetus.
Studies in animals have linked high blood levels of caffeine to premature birth, delivery complications, low birth weight and birth defects when given in very large doses (amounts equal to 12 to 24 cups of coffee a day), and with bone growth problems when given in smaller doses.
| ||Alcohol is definitely harmful for the baby, no matter how much is consumed, especially during the first three months when the baby is forming. There is also a definite correlation between the amount of alcohol drunk during pregnancy and the severity of the symptoms, and also a link with the risk of miscarriage and stillbirth. Evidence shows that even pregnant mothers who only drink in moderation have a greater chance of miscarriage and low birth weight babies than those who do not. Numerous studies have also shown that heavy drinking is extremely damaging for the baby and has the potential to lead to fetal alcohol syndrome. Such babies have low birth weight, with a smaller head circumference and mental retardation is often present. Some affected babies have malformed faces and congenital heart defects.|
The current recommendation from doctors and health experts is that pregnant women should not drink at all. If the urge is too strong, one standard drink is the absolute maximum. However, in the first few weeks of pregnancy, it is difficult to know that you are pregnant and this is a particularly crucial stage for the formation of the baby. So, if you suspect that you are pregnant, or are planning to conceive, you should stay away from alcohol. The risk of miscarriage doubles with more than two drinks per day.
High/Increased Protein Diet
| ||Adequate protein intake can prevent preeclampsia, and a higher protein diet can often successfully reverse preeclampsia.|
Artificial Sweetener Avoidance
| ||Dr Diana Dow Edwards, a researcher, was funded by Monsanto to study possible birth defects caused by the ingestion of aspartame. After preliminary data showed damaging information about aspartame, funding for the study was cut off. A separate genetic pediatrician at Emory University has testified that aspartame is causing birth defects.|
In the book, While Waiting: A Prenatal Guidebook by George R. Verrilli, M.D. and Anne Marie Mueser, it is stated that aspartame is suspected of causing brain damage in sensitive individuals: a fetus may be at risk for these effects. Some researchers have suggested that high doses of aspartame may be associated with problems ranging from dizziness and subtle brain changes to mental retardation.
Increased Fruit/Vegetable Consumption
| ||Women who eat vegetables such as potatoes and turnips while pregnant may increase their child�s risk of developing diabetes, according to a study on mice. Now, researchers have found that bafilomycin, a toxin found in some bacteria called streptomyces that infect vegetables such as potatoes, sugar beets, turnips and radishes, may be a trigger for type 1 diabetes in children who are genetically susceptible. The toxin, which cannot be destroyed through cooking, appeared to affect the development of the pancreas, which could cause type 1 diabetes in susceptible persons, according to researchers. |
Finland, where potatoes are commonly eaten, and Sardinia, where people eat a lot of sugar beets, have the highest rates of diabetes in the world, researchers said. [The Australian June 9, 2003]
Eating apples while pregnant may give new meaning to an apple a day keeping the doctor away. Compelling new research has concluded that mothers who eat apples during pregnancy may protect their children from developing asthma later in life. The study was published in Thorax online April 2007.
This unique longitudinal study tracked dietary intake by nearly 2000 pregnant women, then examined the effects of the maternal diet on airway development in more than 1200 of their children five years later. Among a wide variety of foods consumed and recorded by the pregnant women, the researchers concluded that the children of mothers who ate apples had a significantly reduced risk for the development of asthma and childhood wheezing.
This study focuses on medical evaluations for asthma and related symptoms (i.e., wheezing) when the children were five years old. As a result of the evaluations cited in this research, other than apples, there were no consistent associations found between prenatal consumption of a range of healthful foods and asthma in the 1253 children who were evaluated.
Children of mothers who ate apples during pregnancy were much less likely to exhibit symptoms of asthma (including wheezing), say the researchers who hail from institutions in The Netherlands and Scotland. These same researchers previously reported positive associations between maternal consumption of vitamins A, E, D and zinc with reduced risk of asthma, wheeze and eczema in children.
The only other positive association found between prenatal food intake and risk reduction in the children was with fish, for which the researchers found that children of mothers who ate fish had a lowered incidence of doctor-confirmed eczema.
Increased Fish Consumption
| ||Based on the recommendations of the Environmental Working Group and the U.S. Public Interest Research Group, it is recommended that shark, swordfish, king mackerel and tilefish, tuna, sea bass, halibut, marlin, pike, Gulf coast oysters and white croaker not be eaten by pregnant women and women of childbearing age who might become pregnant due to mercury contamination. It also recommended that nursing mothers and young children steer clear of these fish. In addition, the report says canned tuna, mahi-mahi, cod and pollack should not be eaten more than once a month. |
"The widespread contamination of fish with mercury has given its reputation as 'brain food' a new and disturbing connotation. Mercury is toxic to the developing fetal brain, and exposure in the womb can cause learning deficiencies and delay mental development in children."
A Center for Disease Control report finds that an estimated 375,000 babies being born each year at risk of neurological problems due to exposure to mercury in the womb. The Mercury Policy Project report indicates that at least 10 percent of women of childbearing age have levels of mercury in their bodies that exceed what the U.S. Environmental Protection Agency considers acceptable and this translates to nearly six million women.
It is a tragedy that the modern way of living has damaged a very healthy food with mercury toxicity as a result of burning coal for electricity, which releases mercury into the atmosphere. Generally the larger the fish, the more mercury it contains. It would be best to avoid fish consumption during pregnancy and strictly limit it thereafter in young children. On the other hand, fish oil, containing essential fatty acids, is usually free of mercury as a result of processing and its use has been shown to reduce the frequency of preterm deliveries.

| ||GHB induces �remarkable hypotonia� (muscle relaxation) (Vickers, 1969). It is now gaining popularity in France and Italy as an aid to childbirth. GHB causes �spectacular action on the dilation of the cervix,� decreased anxiety, greater intensity and frequency of uterine contractions, increased sensitivity to oxytocic drugs (used to induce contractions), preservation of reflexes, a lack of respiratory depression in the fetus, and protection against fetal cardiac anoxia (especially in cases where the umbilical cord wraps around the fetus� neck) (Vickers, 1969; Laborit, 1964).|
Conventional Drugs / Information
| ||In December 2005, the Food and Drug Administration warned pregnant women and their doctors away from the antidepressant Paxil because of an increased risk of heart defects in newborns. With this warning, the agency for the first time placed a popular antidepressant - one in the same drug class as Prozac and Zoloft - into its second-highest category for risk of birth defects.|
July 2011. Children whose mothers take Zoloft, Prozac, or similar antidepressants during pregnancy are twice as likely as other children to have a diagnosis of autism or a related disorder, according to a small new study, the first to examine the relationship between antidepressants and autism risk.
Using Kaiser Permanente's patient database, which includes more than 3.2 million people, Croen and her team identified 298 children with an ASD who were born between 1995 and mid-1999, and matched them with 1,507 children without autism who were roughly the same age and were born in the same hospitals.
The authors then cross-checked whether their mothers, in the year before delivery, filled prescriptions for an SSRI, including Prozac, Zoloft, Luvox, Celexa, and Paxil (or their generic versions). The researchers could not confirm whether the mothers actually took the medication, however.
A larger study needs to be done to confirm this relationship, but based upon this discovery, it would seem wise to avoid antidepressants, if possible, during pregnancy.

| ||If a baby is exposed to several endocrine-disrupting compounds in utero, changes may occur that lengthen the period of sensitivity to carcinogens. Therefore, even if the compounds don't cause cancer directly, they may contribute to cancer risk by increasing susceptibility. An embryo and fetus develop at much faster rate than adults. While this development occurs, cell division and growth is rapid. These rapid changes provide many opportunities for mistakes to occur. Since cell division and growth do not occur at this rapid rate in adulthood, the chances of mistakes being made are much more common in an embryo or fetus than in an adult. Additionally, barriers such as the blood-brain barrier are not yet complete in the womb, and mechanisms that help detoxify contaminants do not fully develop until after birth, both of which leave the embryo and fetus more vulnerable still.|
Several human studies suggest a causal relationship between developmental exposure to contaminants and cancer in children and young adults. Examples include occupational exposures of parents and brain cancers in children; pesticides, paints, paint thinners and solvents and leukemia; and cigarette smoke and childhood cancer. Since childhood cancers are so uncommon, prospective studies rarely have a large enough sample to yield conclusive results, and animal studies for developmental exposures and early age or adult cancer are more convincing and extensive than the available epidemiological data.
Animal studies have shown that prenatal and early postnatal exposure to radiation and chemicals causes cancers in the exposed animals later in life. Developmental exposure to carcinogens can increase sensitivity to carcinogens later in life. For example, one study showed that adults who had been exposed to ethylene thiourea (ETU), an industrial chemical, perinatally developed more cancers when exposed to the chemical in adulthood than those exposed only in adulthood.

Pregnant women who are exposed to phthalates, a chemical commonly used in plastics, may be at risk of a shortened pregnancy. Women who were exposed to the chemicals gave birth more than one week earlier than women who were not exposed to them.
The chemicals are added to plastic products such as food containers to add flexibility along with moisturizers, nail polishes, hairsprays and insect repellants and are known to leach out of the products and into the environment. It was previously thought that exposure to phthalates occurred primarily through ingesting contaminated foods. However, researchers found that inhalation and even dermal absorption may also significantly influence a woman�s exposure. [National Institute of Environmental Health Sciences November 4, 2003]
The less you are exposed to synthetic pesticides and chemicals during your pregnancy, the better it will be for your baby now and in years to come.
| ||Smoking in pregnancy is very clearly linked to a higher risk of miscarriages, low birth weight babies and premature babies. There is also a link to risks of stillbirths and babies dying in the first few weeks of life. This is due to nicotine which decreases the amount of blood delivered to the fetus, therefore less nutrients and oxygen is received by the baby. |
The current recommendation of doctors is for the mother to not smoke at all, however if the mother is having difficulty quitting, 3-6 cigarettes a day is the absolute maximum. If you are a smoker, the best time to stop is before you get pregnant because the first few weeks of pregnancy are crucial to the development of the baby. Also, you should encourage other members of the family to quit smoking or not to smoke in your presence because passive smoking may be damaging to the mother and fetus. In addition, smoking around your new-born increases his/her risk of developing asthma and other respiratory disease.

| ||Children of mothers who took calcium during pregnancy were still reaping the benefits seven years later in one Argentinian study. Blood pressure was lower in these youngsters - especially among overweight children - than those in the non-supplement-taking group. [Belizan JM, et al. Brit Med J 1997;315(7103): pp.281�5] Taking calcium may also decrease a woman's chance of developing pre-eclampsia, pregnancy-related hypertension. [Moutquin HM, et al. Can Med Assoc J 1997;157(7): pp.907�19]|
A growing baby acquires most of its calcium during the last trimester of pregnancy; an additional amount is needed during breastfeeding. This translates into a greater need for calcium during and after pregnancy. A pregnant woman who fails to consume adequate calcium -1,200mg per day is recommended - increases her risk of developing osteoporosis later in life, especially if she becomes pregnant again.

| ||Low magnesium levels are common among women suffering from severe nausea and vomiting, says Miriam Erick, M.S., R.D., dietetic manager of Clinical Obstetrics at Brigham and Women's Hospital in Boston. Therefore, magnesium for these expectant moms is critical. Magnesium can also help treat pregnancy-related leg cramps [Dahle LO, et al. Am J of Obst & Gyn 1995;173: pp.175�180] and alleviate severe pre-eclampsia, a serious condition in which high blood pressure, edema and protein in the urine are present in pregnant women. [Brit J Obst & Gyn 1997;104(10): pp.1173�9] Taking prenatal magnesium may also reduce risk for cerebral palsy and mental retardation among very low birth-weight infants. [Schendel DE, et al. J of the AMA 1996;276(22): pp.1805�10]|
In a study of 535 women who were expected to deliver within the one day, subjects received a loading dose of 4g of magnesium sulfate at a 0.5 g/ml concentration in a 60-ml bag compared with 527 women who received an isotonic sodium solution, both over 20 minutes, followed by a maintenance infusion at 2 ml/hour for up to 24 hours. At 2 years, the children of women who received magnesium sulfate had a reduction in total mortality (13.8% vs 17.1%), less cerebral palsy (6.8% vs 8.2%), and less combined death or cerebral palsy (19.8% vs 24.0%) compared with those who received the placebo. There was significantly less gross motor dysfunction and combined death or substantial gross motor dysfunction in the magnesium group versus the isotonic sodium chloride group. There were no serious harmful effects seen with the magnesium sulfate infusion. [JAMA. November 26, 2003;290(20): pp.2669-2676]
| ||Iron is routinely prescribed for pregnant women during the second and third trimesters, when blood volume increases by 50%. The growing baby is also making blood. Hemoglobin, the blood component that carries oxygen to the cells, is composed in part of iron. During pregnancy, your baby receives plenty of this critical mineral because your body absorbs iron more efficiently. [Eskeland B, et al. Acta Obstetricia et Gynecologica Scandinavia 1997;76: pp.822�8]|
There is some controversy about whether iron supplementation is really needed or effective, except for women such as diabetics or those with anaemia, whose iron deficiency is a real threat. [Lao TT, Tami KF. Diabetes Care 1997;20(9): 1368�9] Iron supplementation for anemia often fails because women don't take iron long enough, say researchers at the University of California, Berkeley. They suggest beginning iron supplementation before conception and continuing until breastfeeding is finished. [Viteri FE. Nutr Rev 1997;55(6): pp.195�9]
It is preferable to get your iron in natural foods. Iron supplements may cause nausea and constipation, making the common discomforts of pregnancy worse. Too much iron is also bad for the circulation. If you do need to take iron supplements on doctor's advice, iron chelate is better tolerated by the body and is available from chemists. The U.S. RDA is 30mg.
| ||Inadequate amounts of zinc can lead to central nervous system and other malformations, small-for-age babies and miscarriage. Adding a moderate dose of zinc to your prenatal supplement regimen may also benefit your baby's immunity. [Lastra Md, et al. Arch of Medl Res 1997;28(1): 67�2]|
The U.S. RDA is 15mg.
| ||A small study of infertile women and women with a history of miscarriage suggests that low levels of magnesium may impair reproductive function, and may contribute to miscarriage. Oxidation, a process that is damaging to cell membranes, can lead to loss of magnesium. The same study suggests that the antioxidant selenium protects the cell membrane, thereby maintaining appropriate levels of magnesium. The authors of the study suggest taking both magnesium and selenium supplements.|
Women who have miscarried have lower levels of selenium than women who carry a pregnancy to full term. Although the authors of the above-mentioned study do not specify the exact amount to take, the recommended doses are generally 300 to 400mg per day of magnesium and 200mcg per day of selenium.
| ||Fluoride avoidance reduced anemia in pregnant women, decreased pre-term births and enhanced babies' birth-weight, concludes leading fluoride expert, AK Susheela and colleagues, in a study published in Current Science (May 2010).|
Susheela's team explains that anemia in pregnancy, which can lead to maternal and infant mortality, continues to plague many countries despite nutritional counseling and maternal iron and folic acid supplementation. This is the first examination of fluoride as an additional risk factor for anemia and low-birth-weight babies.
Anemic pregnant women living in India, whose urine contained 1 mg/L fluoride or more, were separated into two groups. The experimental group avoided fluoride in water, food and other sources and ate a nutritious diet per instruction. The control group received no instructions. Both groups supplemented with iron and folic acid.
Results reveal that anemia was reduced and pre-term and low-birth-weight babies were considerably fewer in the fluoride-avoidance group as compared to the control. Two stillbirths occurred in the control group, none in the experimental group.
DHA (docosahexaenoic acid)
| ||According to an article in the American Journal of Clinical Nutrition, healthy full-term infants who are breast-fed for at least four months show greater visual perception skills at early childhood than their bottle-fed counterparts. Testing revealed differences in the maturity of the brain's visual cortex, an important stage in a child's neurological development. [Am J Clin Nutr 2001;73(2): pp.316-22]|
Of the 15 factors analyzed that could potentially influence that rate of visual development in infants, breastfeeding for 4 months or more independently had the greatest positive impact. The only other factor in this study that independently affected the children's stereoacuity at 3.5 years was the mother's consumption of oily fish during pregnancy.
This supports the idea that children may develop improved visual acuity and achieve a higher verbal IQ when breast-fed because they receive a fatty acid, docosahexaenoic acid (DHA) found in breast milk [Arch Dis Child Fetal Neonatal Ed 2001;84: pp.23-7]. The amount of DHA found in breast milk increases with the consumption of oily fish or when otherwise supplemented and decreases when less DHA is consumed. Indeed, testing has revealed that a child's visual acuity directly correlated with the mother's level of DHA in her red blood cells.
During the last trimester of a pregnancy the mother transfers to her fetus much of the DHA needed for the development of its brain and nervous system. As a consequence, she may lose as much as 3% of her brain mass during this time and therefore supplemental DHA may help prevent postpartum depression and ensure an adequate supply for the nursing baby.
The DHA content in the mother's diet reflects the amount of DHA passed on to the baby. If the baby is not breastfed at all, it receives much less DHA, thus hindering and impairing mental and visual acuity. DHA levels of premature infants are especially low since they miss much of that last trimester. Premature babies are also more likely to be bottle-fed.
Vegan diets are devoid of preformed EPA and DHA, while vegetarian diets provide small amounts in dairy products. Vegetarian and vegan women should therefore ensure their diets include sources of alpha-linolenic acid (ALA), the precursor of EPA and DHA, during pregnancy and breastfeeding. Supplemental DHA may be appropriate in some cases. It is suggested that vegans use plant oils with a low ratio of linoleic acid (Omega-6) to ALA (Omega-3), such as flax or canola, as a higher ratio may inhibit the conversion of ALA to DHA..
Essential Fatty Acids
| ||Adequate and balanced essential fatty acid intake is important for the optimal neurologic development of the baby. Fish oil, containing essential fatty acids, is usually free of mercury as a result of proper processing.|
Lecithin / Choline / GPC
| ||According to a study, the important nutrient choline �super-charged the brain activity of animals in utero, which resulted in the creation of larger cells that were quicker at firing electrical �signals� that release memory-forming chemicals.|
These significant changes in the brain could be used to explain how choline improved learning and memory in animals in earlier behavioral studies. Researchers said this data could mean boosting cognitive function, diminishing age-related memory decline and decreasing the brain�s vulnerability to toxic insults in children. This research has led to the decision to raise choline to the status of an essential nutrient, particularly for pregnant and nursing women.
Choline can be found as a naturally occurring nutrient in egg yolks, milk, nuts, fish, liver and human breast milk. [Journal of Neurophysiology April 2004;91(4): pp.1545-55]

Vitamin Folic Acid
| ||In 1992, the U.S. Public Health Service recommended that all women of childbearing age consume additional folic acid. This means that increased consumption of folic acid is crucial not only during pregnancy, but also before conception. Women should take at least 400mcg of folic acid daily. It has been estimated that if all women of childbearing age met this allowance, the number of neural tube defect cases in the United States could decrease by at least 50%. [CDC. Morbidity and Mortality Weekly Report, 1992; 41(RR-14)]|
Although foods such as dark-green leafy vegetables provide a reasonable source of folic acid, most women don't reach the recommended 400mcg through diet alone. [Johnston RB, Staples DA. 1997. J Am Med Assoc 1997;278 (11): pp.892�93]
Neural tube defects: (spina bifida): In one study, women who consumed 400mcg of folic acid per day cut in half their chances of having babies with birth defects of the brain and spinal cord, such as spina bifida. Whether a baby develops these defects is determined in the first days after conception (the critical time may be day 27-28) - perhaps before a woman knows she is pregnant. Even with food fortification it can be hard to get enough, so health experts recommend that every woman of childbearing age take a daily dietary supplement, such as a multivitamin, containing 400mcg of folic acid.
In another study, one-half of women who had delivered children with spina bifida or anencephaly were found to have had a poor diet during the pregnancy which ended with a child with a neural tube defect. 103 of these women received dietary counseling prior to their next pregnancy while 71 controls received no counseling. Of those who improved their diet, all delivered normal children, while all 8 out of 186 newborns with NTD were born to women who ate a poor diet during their first 6 months of pregnancy [Laurence KM. Nutr Health 2( 3/ 4), 1983].
Scientists currently theorize that women who give birth to babies with neural tube defects are less able to convert homocysteine to methionine, and that high levels of homocysteine may cause birth defects. Folic acid, along with vitamin B12, is required for this biochemical conversion, as well as new tissue production and growth in both baby and mother.
Downs: Mothers with a genetic abnormality that hinders how the body processes folic acid were 2.6 times more likely to have a child with Down syndrome than mothers without that genetic defect. Millions of women appear to have this genetic abnormality, yet the risk of having a child with Down syndrome actually is small - one in 600 births. If you have this mutation and you happen to have a very poor diet, it magnifies the problem; the researchers call this a gene-nutrient interaction. The March of Dimes estimates there are 250,000 Americans with Down syndrome. (American Journal of Clinical Nutrition October 1999)
Cleft palate: Only high pharmacological doses (6mg per day) of folic acid in the critical period of the primary and the secondary palate development seem to be effective for the reduction of clefts. Doses less than 1mg of folic acid cannot reduce these birth defects.
Case Report: After giving birth, a woman developed severe depression, confusion, disorientation and hallucinations. Over the next 19 months, trials with numerous medications and electroshock therapy were unsuccessful. Folic acid deficiency was diagnosed and folate supplementation was started. In 10 days, she was completely cured.
Folic acid supplementation during pregnancy was associated with a reduced risk of acute lymphoblastic leukemia in children in Western Australia. Lancet 2001;358(9297): pp.1935-40 [Lancet 2001;358(9297): pp.1935-40]
Vitamin B Complex
| ||Many naturopathic and other doctors suggest using vitamin B complex (50mg per day) with additional vitamin B6 and folic acid (800 to 1000mcg per day) for women planning to become pregnant and for those who are pregnant. These preventive measures are supported by studies that suggest a connection between recurring miscarriages and problems metabolizing methionine and homocysteine in the body. Folic acid, vitamins B6 and B12, and betaine all play a role in the proper use of these compounds.|

Health problems ranged from seizures and growth failure to rickets. [Daaboul J, et al. J of Perinat 1997;17(1): 10�4] Congenital cataracts have also been linked to low levels of vitamin D. [Blau EB. The Lancet 1996;347: p.626] Other research points to vitamin D as a possible adjunct therapy for premature babies with respiratory distress syndrome [Nguyen TM, et al.

It would be wise to make sure you are getting some vitamin D in supplement form or adequate sun exposure during your pregnancy. In analyzing over a million records it was found that babies born in the autumn weighed more than those born at springtime. In later life, low birth weight was associated with increased blood pressure, cholesterol levels, some forms of obesity and a decrease in lung function. Babies born in autumn also lived 4-7 months longer. This is just one more reason to take care of yourself and your child during this time. It is also something you can tell your child you did with them in mind when they are older.
Vitamin B6 (Pyridoxine)
| ||Vitamin B6 is necessary for optimal brain development and is an essential coenzyme for neurotransmitter synthesis. [Gerster II. Z. Ernahrungswiss 1996;35(4): pp.309�17] One animal study found that vitamin B6 helped prevent the formation of cleft palates. [Jacobsson C, Granstrom G. Cleft Palate Craniofacial J 1997;34(2):95�100] Like magnesium, vitamin B6, together with vitamin B1, may also ease pregnancy-related leg cramps. [Avsar AF, et al. Am J of Obst & Gyn 1996;175(1):233�4]|
The U.S. RDA is 2.2mg.
| ||The U.S. RDA is 4,000 IU or 800mg. NOTE: Be very careful to avoid high doses of over 10,000 IU per day during pregnancy or if there is a likelihood of becoming pregnant soon.|
| ||Quercetin inhibits conversion of vitamin A to retinoic acid. Retinoic acid is needed to help control gene expression in unborn babies. "It's possible that a diet rich in quercetin during pregnancy may upset retinoic acid production, and lead to incorrect development and birth defects," Dr. Kitson says. "It has recently been found that some baby boys born to exclusively-vegetarian mothers (some vegetarian diets are high in naturally occurring quercetin) have urogenital abnormalities."|
However, there is currently no direct evidence indicating that quercetin causes chromosomal changes in the fetus. As a maximum safe dose for pregnant women or nursing mothers has not been established, a cautious recommendation would be that high doses of quercetin be avoided during the early part of pregnancy until further research is done.
