Influence of Different Types of Dietary Fat on the Fatty Acid Composition of Some Serum Lipid Fractions in Infants and Children

Abstract

The serum lipids of groups of young infants, children and mothers at parturition, maintained on different types of diet, were analyzed. In some of the infants the type of dietary fat was changed. The different types of diet, probably because of their varied linoleic acid contents, influenced both the total amount and fatty acid pattern of the serum lipids. A competition between the ω3, ω6 and ω9 types of fatty acids was demonstrated. Insufficient supply of linoleic acid due to exclusive feeding of cow’s milk was most reliably detected by the determination of 5,8,1l-eicosatrienoic acid in serum lipids.
