Intrauterine changes in plasma cholesterol and lipoprotein concentrations have been linked to the development of the adrenal gland (utilization of cholesterol) and liver (production of cholesterol by new synthesis). At term birth, racial and gender differences have been observed with white compared to black, and female compared to male, infants having higher cholesterol concentrations. Within hours of the beginning of oral feeding, total and LDL cholesterol rise significantly. Little further increase occurs after 7 days, and the concentration seen after this time is highly dependent upon the cholesterol and polyunsaturated fat content of the diet. By 12 months of age, investigators cease to find any effect of the milk source fed earlier in infancy on cholesterol and lipoproteins. This is not evidence that diet no longer influences cholesterol and lipoprotein concentrations, but only that individual lipid intakes are varied and difficult to quantitate. Cross-cultural comparisons of infants at this age in fact provide strong suggestive evidence that a large environmental component determines the circulating cholesterol and lipoprotein concentrations seen at one year and beyond.
