Abstract
Rats were fed with experimental diet including cereal protein of polished rice, buck wheat, Japanese barnyard millet, etc. of the type commonly eaten in the Tohoku area.
The cholesterol level in the serum and in several organs was measured and the protein content as well as its influence was compared with that of casein. The test groups were fed with high level protein of buckwheat, barnyard millet, polished rice and casein all showed cholesterol levels lower than the 5% protein groups. Almost no difference among the varieties of cereal protein was discovered. Further, these test groups showed higher cholesterol levels than the standard diet or 30% casein groups.
In the case of restricted diet, the serum cholesterol level was generally lower than that with an ad libitum diet. Also in the case of a low protein diet the cholesterol level is not very high. The cholesterol of the liver and lungs and the faecal kiliani-reactive substance level showed a tendency opposite to that of the serum cholesterol level in ad libitum case.
