Reducing consumption of foods of animal origin in favor of more plant-based diets is a major environmental, public health and economic challenge. Data on the health effects of highly vegetalized diets are available only in adults. Few studies report the effect of the level of vegetalization of the maternal diet during pregnancy on the mother's health, and the development and health of the child. The VEGALIM project aims to describe the level of vegetalization of pregnant women's diets and the nutritional quality of their diets early in pregnancy (first trimester) and late pregnancy, and to explore the potential effects on their plasma lipid profile that may impact on their health during pregnancy and the health of the newborn.
