title: Cholesterol and triacylglycerols in human breast milk before and after nursing.
abstract: Cholesterol and triacylglycerols concentrations were estimated in human breast milk taken before and after nursing at the period of 1 week, 3 months, and 6 months after delivery. In all postfeeding samples significantly higher concentration of cholesterol and triacylglycerols was found as compared with the appropriate samples obtained before the feeding. In cholesterol concentration such difference was most remarkable in the milk of mothers who were breast feeding their infants over 6 months. The highest cholesterol concentrations were found during the first week after the delivery, whereas the highest concentrations of triglycerides were found 6 months after the delivery. The elevations of the lipid levels were not associated with changes of osmolality and/or electrolytes (Na+, K+, Ca2+) during the nursing.
