[Evolution of serum cholesterol and cholesterol lipoprotein fraction levels in the neonatal period].

A parallel study of serum lipoproteins was carried out in 2 groups of neonates fed either humanized milk (HM) or breast milk (BM): 1. Mean levels at birth were higher than those reported in the literature; this may be due to peripheral venous blood drawings rather than cord-blood. 2. There was a larger increase in total cholesterol (TC) levels in children fed with BM at 10 days of life. 3. The significant correlation (r = 0.55; p less than 0.02) between TC and HDL cholesterol at 10 days in children fed with BM was not found in children fed with HM. These findings suggest 2 questions: 1. Even though it is rich in cholesterol, BM may have a better protective effect against atheroma; from a preventive point of view, is it necessary to check only the daily cholesterol intakes? 2. Since BM is a model for nutritionists, is it justified to reduce the cholesterol level in HM?
