Abstract
The cholesterol levels in the serum, liver, lung and adrenal were influenced by the quality and quantity of the dietary protein. High casein diet showed a notable lowering effect on the cholesterol levels in the rats.
It was examined whether high casein hydrolysate diet with unbalanced amino acid showed any lowering effect on the serum cholesterol level or not to observe the effect of dietary amino acid balance on the cholesterol metabolism. Results showed that all free, esterified and total cholesterol levels in the serum did not decrease on high casein hydrolysate feeding and consequently unbalanced amino acid diet had no effect of lowering cholesterol level.
