In human milk, the role of lipids as a source for the adequate growth and development of the infantis highlighted. The lipidic system of breast milk, responsible for approximately 50% of calories,is structured for the newborn and the infant. Digestion and absorption of lipids are facilitatedby the organization of fat, the type of fatty acid (palmitic, oleic, linoleic, linolenic acids, etc.), thecomposition of triglycerides and the lipase stimulated by bile salts. In addition, milk contains docosahexaenoic acid, which allows optimal neurological and immunological development. Althoughthe lipid structure of breast milk is extremely complex, it should serve as a model for the dynamicsof the lipid composition of infant formulas. The addition of long-chain fatty acids (arachidonicand docosahexaenoic acids) linked to phospholipids in infant formulas can contribute to a betterdevelopment of infants, as well as acting on the immune system and metabolic imprinting, reducingthe risk of chronic non-communicable diseases. Infants receiving formulas with palmitic acid intheß-2 position have a higher lactobacillus count in the feces, when compared to those receivingformulas with palmitic acid in the ß-1 and ß-3 positions, promoting the maintenance of intestinaleubiosis. Infants receiving formulas with ß-2 palmitic acid present bone health similar to infantsbreastfeeding, as fecal calcium loss does not occur.
