Nutrition Lipidique Maternelle Et Ses Effets Sur La Santé De L’homme

Maternal dietary polyunsaturated fatty acids (PUFA) ensure optimal infant development. Observational studies reported in infants that a specific deficit in n-3 PUFA intake in pregnant women was associated with a reduction in their visual acuity, and a low docosahexaenoic acid (DHA) content associated with a high level of n-6 PUFA in breast milk was negatively associated with lower cognitive development. They agree with the hypothesis that unbalanced n-6/n-3 ratio could promote the development of adipose tissue and obesity. Moreover, they suggest that long-chain n-3 PUFA consumption during pregnancy may prevent the incidence of allergic diseases in children. Lastly, specific association between the maternal ingestion of food groups and the infant health has been studied mainly on allergic outcomes (fish, dairy products). Nutritional recommendations for PUFA intake in pregnant and lactating women were mainly based on brain development data, corresponding to breast milk levels of 10% of total fatty acids for linoleic acid, 1.5% for alpha-linolenic acid and 0.4% for DHA.
