Abstract:
The Danish Nutrition Council has examined the latest scientific literature on nutrition during pregnancy to evaluate the basis for the existing official recommendations. The recommendation to overweight women to gain only eight kilo should be accompanied with a recommendation to lose weight pre-conceptionally. Individualised recommendations should be provided in the prevention of iron deficiency, and the recommendation for calcium should include information on quantity. The recommendation of periconceptional folic acid supplementation does not benefit unplanned pregnancies. Arguments exist for adding a recommendation for vitamin D.
