Plasma lipid and apolipoprotein concentrations in full term infants fed formula supplemented with long-chain polyunsaturated fatty acids and cholesterol.
Recent data indicate that supplementation of infant formula with omega-3 and omega-6 long-chain polyunsaturated fatty acids might offer developmental benefits for full term infants. We investigated biochemical consequences of feeding formula supplemented with egg lipids to provide long-chain polyunsaturated fatty acids and compared triglyceride, cholesterol, lipoprotein cholesterol (HDL2-cholesterol, HDL3-cholesterol, non-HDL-cholesterol) and apolipoprotein A-I, A-II and B concentrations in full term infants fed either conventional formula (n = 10) or a formula supplemented with omega-3 and omega-6 long-chain polyunsaturated fatty acids and cholesterol in amounts similar to those found in mature human milk (n = 12). At the age of 5 days, cholesterol, non-HDL-cholesterol and triglyceride concentrations were significantly higher in infants fed supplemented than in those receiving conventional formula. At the age of 30 days, triglyceride concentrations were significantly higher with supplemented than with conventional formula. Thereafter throughout the study, no significant differences were seen between the two groups.


CONCLUSIONS
Full term infants fed formula supplemented with omega-3 and omega-6 long-chain polyunsaturated fatty acids and cholesterol showed significantly higher plasma cholesterol and triglyceride concentrations than infants receiving conventional formula on day 5 and on days 5 and 30, respectively. Thereafter no appreciable effect of diet on plasma phospholipid, triglyceride, cholesterol, lipoprotein cholesterol and apolipoprotein concentrations were seen.
