Dietary cholesterol and fats at a young age: do they influence cholesterol metabolism in adult life?
The effects of dietary cholesterol and fats on cholesterol metabolism later in life were studied in Mongolian gerbils. Three groups were given a basic diet with soybean oil, palm kernel oil amounting to 8.75% (w/w), or the basic diet only. In three other groups, cholesterol (0.05%) was added to the above diets. Measurements were done in animals of the third generation on the diets. On all diets, teh serum cholesterol of the sucklings was increased as compared to the young that were suckled by mothers on the basic diet only, while body cholesterol was highest in sucklings of mothers on the basic diet or palm-kernel-oil-enriched diets. When the diets were replaced by the basic diets at 6 months of age, serum cholesterol was still increased at 12 months of age in animals previously fed on the cholesterol-enriched diets. Tissue cholesterol did not differ. However, after a challenge with cholesterol at that age, the differences in serum cholesterol were not significantly different.
