Supplementation
B Vitamins – The B vitamins have man beneficial effects in preconception care and in pregnancy. Deficiencies of all of the B vitamins have been associated with fertility problems, miscarriage, neonatal or perinatal death, fetal abnormalities, and low birth weight babies.
Folic Acid – Requirement for folic acid doubles during pregnancy. It is required in the 3 months pre and post conception to prevent neural tube defects. Folic acid supplementation throughout pregnancy also improves birth weight and APGAR scores. Pica, unusual food cravings are commonly experienced in pregnancy and indicate a severe nutritional lack, often a mineral deficiency.
Calcium – Low calcium contributes to increased risk of pregnancy-induced hypertension and pre-eclampsia.
Magnesium – Low magnesium may lead to premature labour and pre-eclampsia and love birth weight. High blood pressure is also associated with low magnesium. Leg cramps, common in pregnancy during the third trimester respond to magnesium supplementation.
Fatty Acids – Essential fatty acids are an essential part of the cell membrane and are important in the formation of new tissues and for normal cell signaling responses. Healthy sperm is highly dependent on an adequate supply of essential fatty acids, and the developing foetus has high requirements for essential fatty acids. Omega-3 fatty acids are especially important for visual and cortical function. Foetal DHA correlates positively with birth weight. Supplementation with omega-6 fatty acids may prevent hypertension in pregnancy.
Vitamin E – Vitamin E improves sperm motility and is effective in the treatment of low sperm count and abnormal sperm. Vitamin E is also effective in preventing habitual miscarriage.
Zinc – Zinc is commonly deficient with 67% of Australian men and 85% of women having marginal dietary levels. Zinc is considered to be the single most important nutrient for trying to get pregnant or pregnant women. It is also vital for sperm health and increases fertility in women. Zinc is present in large amounts in semen and supplementation increases sperm count and sperm motility.
During pregnancy inadequate zinc leads to common problems such as stretch marks, cracked nipples and prolonged labour. More serious problems such as foetal growth retardation and congenital malformations may also result from zinc deficiency.
Postnatal depression has been linked with zinc deficiency by several researchers and zinc deficient babies cry excessively and are difficult to calm.
Vitamin A – Vitamin A is necessary for the health of the cilia in the fallopian tubes, for the health of the testes, for sperm production and is important for zinc metabolism. Vitamin A is toxic in pregnancy only at daily doses above 25,000IU however doses below 10,000IU are generally recommended to allow a considerable margin for safety.
Vitamin C – Vitamin C improves all semen parameters. Even a marginal deficiency causes oxidative damage to sperm, resulting in reduced sperm motility and viability. In the female, vitamin C is necessary for maturation of the pre-ovulatory follicle.
Selenium and Taurine – Selenium deficiency is associated with decreased sperm motility and increased numbers of abnormal sperm. Taurine is also important for sperm motility. In females, selenium deficiency is associated with infertility, spontaneous abortion and neural tube defects. One-quarter of infant mortality has been linked with selenium deficiency.
Things to Avoid
Foods to avoid are products containing white flour and sugar.
Refined carbohydrates – Refined carbs have very little nutritional value yet they still require the presence of vitamins and minerals to be metabolized. So they cost the body nutrients without providing any to replace what was used up. A diet high in products containing sugar depresses the immune system, and sugar competes with vitamin C entering the immune cells.
Green potatoes – are toxic and should be avoided.
Fats and fried foods – avoid animal fats and fats or oils which have been heated.
Additives – almost everything which comes in a can, packet or bottle has something added to preserve it, enhance it’s colour, taste or texture. This also includes processed meats such as salami – they contain preservatives.
Salt – Avoid salting your food if that you are eating is already pre-prepared – this includes bread.
Coffee and tea – Replace coffee and tea with herbal teas, but if it is too difficult to allow yourself 2 cups of tea per day. Caffeine adversely affects reproductive health. It interferes with the ability of the sperm to swim forward and reduces fertility in women. It also inhibits the absorption of iron and destroys B vitamins. There have been links with caffeine consumption and chromosomal damage, and consumption during pregnancy is associated with spontaneous abortion and congenital abnormalities.
Alcohol – There are direct effects on fertility for both partners regarding the consumption of alcohol. Considering the length of time to form mature sperm and egg it should be avoided by both partners for at least 4 months prior to conception. Studies have noted an increase in miscarriage and chromosomal malformation. It also depletes the body of essential vitamins and minerals essential for the formation of sex hormones and proper fertility.
Allergens – Do not eat a particular food if you suspect an allergy or intolerance to it.
The acid/alkali balance in your diet is very important. If cervical mucus is too acidic it will destroy sperm and will also be a place less inviting for an embryo to implant.
The aim is to get your body in peak condition prior to conceiving, which includes strong digestion and immune system. The effect of stress, addressing the fear of miscarrying, being ready to parent a child etc, should not be underestimated, particularly if such thoughts have been hanging around for a while. Stress can delay ovulation which in turn affects the health of the embryo. So find many ways to relax and reduce your workload and responsibilities.
