title: Significance of lipid consumption during lactation.
abstract: Human milk lipids are the main source of energy to support optimum growth of the breast-fed infant. The content and composition of milk lipids come from three main sources of fatty acids: the diet, mobilization of body fat stores and fatty acid synthesis de novo by the mammary gland. On account of these, the consumption and composition of the lipids from the diet and also the nutritional state, specifically the body fat percentage of the lactating woman, are elements that maintain a close relation with the content and composition of milk lipids which translates into the energy content given to the baby. The evidence suggests that the body fat stores significantly provide the demand imposed by lactation, and under suboptimal nutritional conditions where body fat stores are depleted, dietary lipid consumption is essential. It is necessary to elucidate the physiological regulatory mechanisms involved in the utilization of dietary lipids on milk synthesis. This information will be of great practical value, since it may allow the development of optimum diets for lactating women.
