Abstract
Although the role of dietary cholesterol was discounted by Keys et al. about a decade ago, practically all recent investigators (10-16), demonstrated its positive effect on the serum cholesterol level. In particular the multiple regression equations, reported in 1968 by the American Heart Association, [(1) and (2) in page 31] show the important effect of the dietary cholesterol together with both saturated and polyunsaturated fatty acids in the diet.
Therefore it seems us worth-while describing the amount of cholesterol along with fatty acids in the animal foods taken daily by the Japanese. In the present study 20 kinds of fish were analysed and the cholesterol content estimated in the meat, both white and blood color, skin, viscera, and in some cases roe and sperm. Fishes of in and out of season were also investigated.
