The nutritive value of various carbohydrates and the supplementary effect of inositol were investigated.
Male Wister young rats were maintained by basic diet containing 65.5% sucrose, 22.0% casein, 9.0% oil, 2.5% salts and 1.0% vitamins. Then 3% sucrose in the basal diet were substituted by other carbohydrates; mono or oligo saccharide group (glucose, lactose, xylose), poly saccharide group (dextrin, α-cornstarch, β-cornstarch) and non calorie poly saccharide group (pectin, agar, cellulose).
Each experimental group was divided in to two groups with or without inositol.
The experimental results are:
1) Glucose, β-cornstarch and cellulose effected increasing the weight of the rats but experiments that used the other carbohydrates proved to have no effects.
2) Addition of inositol to mono-, di saccharide and poly saccharide well effected increasing the weight of the rats. But addition of inositol gave no effects to non calorie poly saccharide group.
3) Diet efficiency, protein efficiency, and calorie efficiency raised on glucose, β-cornstarch and lactose with inositol.
