Three different kinds of semipurified diets with the content of synthetic sweetener, palatinit, were ad bibitum fed to male albino growing rats for 31 days (Exp. 1). Food consumption, food efficiency and body weight gain of rats were on the decrease with the content of palatinit in diet. Apparent absorption of dietary minerals was not significantly changed even though palatinit was added to diet at 1%. However, apparent absorption of dietary zinc, copper, iron, manganese, calcium or magnesium was obviously increased when the palatinit content in diet was elevated to 5%. It was suggested that some changes in mineral metabolism within the body, especially calcium, phosphorus or iron, were induced by feeding rats with the diet supplemented with palatinit at the lavel of 1% or 5%. In experiment 2,male albino growing rats were ad bibitum fed for 31 days one of three kinds of semipurified diets. Cellulose was included at 5% in one diet, and in the others, another sweetener other than palatinit, L-sweet was contained at 1% with or without 5% of cellulose. In rats fed the non fiber diet containing 1% of L-sweet, properties of their stool were fairly loose, in addition to that their food consumption and body weight gain were less than the other groups. However, by supplementation of cellulose at 5% to the diet contained L-sweet, the state of stool was recovered normal; besides, food consumption and body weight gain of rats were enhanced. Apparent absorption of dietary minerals except calcium was a little but significantly higher in rats fed the non fiber diet containing 1% of L-sweet, compared to that in rats fed cellulose containing diets. In the liver of rats fed L-sweet containing diets, calcium content was a trend to be low. Wheareas, the liver iron content was higher than the other group.
