Nutrition of Pregnant and Lactating Women in the First 1000 Days of Infant.

Nutrition for pregnant and breastfeeding women is fundamental to the development of the child in its first 1000 days and beyond. To evaluate the adequacy of this nutrition, we have relied on historical dietary surveys and on personal French studies (4 studies from 1997 to 2014) involving dietary surveys over 3 days (3D-Diet). Furthermore, our team specialized in lipids has measured the fatty acids of breast milk, which reflect the dietary intake of lipids, from breast milk (1997-2014) and from the lipids of cord blood and maternal fat tissue, in 1997. According to our results, pregnancy needs require an additional 300 Kcal, but surveys show a bad equilibrium of macronutrients: an excess of proteins of fetus [17% of total energy intake (TEI) vs. 15%], excess of fats (45% vs. 35%), excess of saturated fatty acids (SFA), not enough polyunsaturated fatty acids (PUFA), particularly omega 3, and a deficit in carbohydrates (45% vs. 55%). There is also a deficiency in calcium, iron, magnesium, zinc, and vitamins D, B6, B5, and folates. Breast milk adequately provides all the macronutrients necessary for the growth of the child. Proteins and carbohydrates vary little according to the mother's diet; on the other hand, its composition in lipids, trace elements, and vitamins is highly variable with the mother's diet of breast milk. In our study in 2014, in 80 participants, the diet was low in calories (1996 Kcal vs. 2200 Kcal RDA), normoprotidic, normolipidic, but low in carbohydrate, especially polysaccharides. We note a very insufficient intake of fish and dairy products, and therefore calcium, but also magnesium, zinc, iron, and vitamins D, E, B6, and folate. Consequently, if the mother does not achieve a diet adequate to her needs during pregnancy and breastfeeding, it will be necessary to resort to medicinal supplements in minerals, trace elements, vitamins, and omega 3.
