Does a Diet With the Recommended Amount of Polyunsaturated Fatty Acids, Increase Their Proportion in Maternal Milk?

The primary evaluation criterion is the level of α-linolenic acid in milk on the 21st postpartum day.

The α-linolenic acid level of breast milk at the 45th postpartum day;

The fatty acid content of breast milk on the 21st and the 45th postpartum days;

The cytokine content of breast milk on the 21st and the 45th postpartum days: IL-6, TNFα, TGFβ

The immunoglobulin A and G content of breast milk on the 21st and the 45th postpartum days;

The lactoferrin content (antimicrobial factor) of breast milk on the 21st and the 45th postpartum days;

The hormone content of breast milk on the 21st and the 45th postpartum days: adiponectin, leptin, insulin;

The oligosaccharide content of breast milk on the 21st and the 45th postpartum days;

The breast milk microbiota content on the 21st and the 45th postpartum days;

the bacterial intestinal microbiota content from the feces of the newborn on the 21st postpartum day;

the fatty acid content of the women red blood cells of the woman before the 7th month of pregnancy and on the 21st postpartum day.

the breast milk lipidome on the 21st postpartum day: 26 lipid classes comprising more than 300 different lipid species (in addition to the total fatty acid analyses of breast milk, in order to make a complete description of the lipid species provided);

the maternal milk metabolome on the 21st postpartum day: metabolites, hormones and other signal molecules (this analysis complements the previous ones by producing a complete description of non-lipid metabolites in breast milk);
