Abstract
Three sorts of experimental diet having different levels of gelatin and rice protein were given to the rats, and serum and organ cholesterol levels were determined.The diets tested contained, (1) 5% gelatin-1-30% rice protein, (2) 5% gelatin+50%, rice protein, and (3) no protein.The serum and organ cholesterol levels did not show a reasonable change and remained in the normal range in all 3 cases.It was confirmed that the quantity of inferior protein had no influence on cholesterol metabolism.The body weight increase of rats fed with 5 of gelatin-1-5, 00 of rice protein was excellent, and an improved effect of mixed protein diet was notable. The cholesterol level by the protein-free diet was rather low.
