Abstract
The weanling rats were fed on casein, rice and wheat respectively as source of dietary protein, and the relation of the occurrence of fatty liver with dietary lysine, threonine and methionine content was investigated.
The normal level of fat was maintained in livers of rats fed casein, rice and wheat diet containing 0.63-0.66% lysine, 0.53-0.54% threonine and 0.53-0.59% methionine, or 0.63-0.66% lysine, 0.53-0.54% threonine and 0.19-0.23% methionine, whereas rats fed diet containing 0.4% lysine, 0.20-0.23% threonine and 0.53-0.59% methionine showed increased fat deposition in liver.
The fat deposition was decreased by supplying diets containing much methionine, lysine and threonine, or by reducing the amount of methionine in the diet.
