Pregnancy means an adjustment of important physiological processes. This contains certain consumption habits or lifestyle factors that may harbour higher health risks for the future mother and her unborn child compared to the rest of the population.

Recognise risks, start life with healthy nutrition

Pregnant women and breastfeeding mothers are among the particularly sensitive groups that require special attention in risk assessment. The BfRshort forGerman Federal Institute for Risk Assessment has compiled important assessments and recommendations for the consumption of food and beverages during pregnancy and breastfeeding.

Food supplements and micronutrients during pregnancy

A balanced and varied mixed diet contributes to optimal nutrition for the pregnant woman and her unborn child. In addition, supplementation with folic acid and iodine is recommended for pregnant women.

Folic acid

In addition to a balanced diet, pregnant women are recommended to take a food supplement containing folic acid, as this can reduce the risk of malformations of the nervous system (neural tube defects, such as spina bifida, commonly known as "open back"). Women should start taking it at least four weeks before the start of the pregnancy or from the time they want to have children - and continue until the end of the first trimester. The recommendation is: 400 μg of synthetic folic acid per day or equivalent doses of other folates in tablet form.

Iodine

It is also difficult for pregnant women in Germany to achieve the desirable iodine intake of 230 µgshort formicrogram per day through nutrition alone. In addition, an adequate iodine supply for the foetus or infant is an important prerequisite for optimal physical and mental development.

It is therefore recommended that pregnant women and breastfeeding mothers - after taking an iodine history - take an individual supplement of 100 (to 150) µgshort formicrogram of iodine tablets per day.

Supplementing with other micronutrients during pregnancy: medical advice is required

Whether other nutrients need to be supplemented must be decided on a case-by-case basis. Any additional intake of other micronutrients should always be preceded by medical advice. Whether, for example, iron needs to be taken additionally during pregnancy is checked by laboratory diagnostics during medical check-ups.

Under no circumstances should you self-medicate with food supplements, over-the-counter products or seemingly harmless vitamin or natural preparations during pregnancy.

Nutrition during pregnancy and breastfeeding

A balanced and varied mixed diet is important during pregnancy. It not only has a short-term but also a long-term effect on the health and well-being of mother and child. Optimum development and growth of the unborn child require adequate nutrition.

Liver consumption during pregnancy

Pregnant and breastfeeding women have a higher need for vitamin A compared to other women. On the other hand, excessive vitamin A intake, especially in the first months of pregnancy, particularly via food supplements, is associated with an increased risk of malformations in the child. Since the 1990s, it has been recommended that pregnant women and infants should refrain from consuming liver from all animal species due to the very high vitamin A concentrations in slaughtered animal liver, and that pregnant women and infants should be very cautious when consuming products containing liver. In view of recent monitoring results (BVLshort forGerman Federal Office of Consumer Protection and Food Safety, 2016), this recommendation is upheld.

Special considerations for fish and game

Fish contains important nutrients, in particular it is rich in iodine, vitamin D and long-chain omega-3 fatty acids such as docosahexaenoic acid (DHA). The German Nutrition Society (DGE) therefore recommends eating oily fish once or twice a week during pregnancy and breastfeeding. If you do not eat oily fish, you should supplement with DHA. In addition, pregnant women are advised to consume mainly fish species that contain comparatively low concentrations of mercury. Fish species with a potentially higher methylmercury content, such as monkfish, halibut, perch or hake, should be avoided by pregnant women.

Eating game meat before and during pregnancy is not recommended if it was shot with lead-containing ammunition. Children should not eat game meat before the age of seven.

Women of child-bearing age, including pregnant and breastfeeding women and children, should also avoid eating wild boar offal as a precautionary measure, as game offal, especially wild boar offal, can contain high concentrations of PFAS, dioxins and PCBs.

Vegetarian nutrition during pregnancy and breastfeeding

A vegetarian nutrition with milk (products) and eggs (ovolacto vegetarian) during pregnancy and breastfeeding can cover the need for most nutrients with a targeted food selection. The recommendation to supplement folic acid before and in the first trimester of pregnancy as well as iodine during pregnancy and breastfeeding naturally also applies to a vegetarian diet. If you do not eat fish regularly, it is recommended to also supplement DHA during pregnancy. In addition, the Gesund ins Leben network advises women on a vegetarian diet to seek specific counselling to ensure an adequate supply of nutrients during pregnancy.

Vegan diet during pregnancy and breastfeeding

A purely vegan diet during pregnancy and breastfeeding does not provide sufficient nutrients. 

However, if a vegan diet started before pregnancy is to be continued, qualified nutritional counselling and - in addition to taking folic acid and iodine - the intake of other supplements are necessary to ensure the supply of essential nutrients. In particular, vitamin B12 should be supplemented and monitored by a doctor if applicable, as an undersupply of vitamin B12 can possibly lead to damage to the child's nervous system.

Alcohol, smoking and other risks

Foodborne infections

Infections during pregnancy should be avoided as they pose an increased risk to the pregnant woman and the unborn child. Personal hygiene and food hygiene is particularly important for preventing infections. Foods that comparatively often contain pathogens should be avoided or heated sufficiently before consumption. These include, in particular raw or insufficiently heated food of animal origin, various types of cheese and fish products, raw sprouts, frozen berries, as well as delicatessen and antipasti (e.g. olives) from open containers, in restaurants or canteens. Fresh fruit and vegetables should be washed carefully before consumption. Vegetables that have come into contact with soil should be stored separately from other foods and heated sufficiently before consumption.
