It has been a general rule to estimate the amount of SDA as 10% of his basal metabolism which seems nearly a function of body size. But SDA should be rather more correlated with the amount of food intaken which is a funktion of working intensity as well as the body size. This is not only a logical, but a practical problem as a muscular worker takes nearly 4000Cal. for a day. The test meals are graded merely by their calories, but contain same ratios of three caloric nutients as shown in table I. As the conclusion of this experiment, we recognized a proportional relation between SDA and calories of foods, except the SDA for 3 hours right after the meals which is almost invariable in every case and supposed to come from digestive action.
Digestibility of pressed grains we e examined about 4 healthy persons who took for two days experimental diets which consist of (A) the pressed wheat and polished rice mixture (1:1) (the pressed wheat period), (B) the pressed barley and polisheb rice mixture (1:1) (the pressed barley period), (C) the ‘udon’ (prepared from wheat flour and as like as macaroni) and polished rice mixture (1:1) (the wheat flour period) and (D) the polished rice (the polished rice period). Eeach diets contain some vegetables, beans, fishes anb seasonings as usual. From the above experiment, digestibility coefficients were calculated and compared with each other. The results are as follows: (1) Digestibility of the pressed barley is better than that of pressed wheat, (2) the wheat flour is better than the grain such as the pressed wheat, (3) the light flour (80% flour) is better than the dark flour (90% flour).
Poor digesion of the blood powder's protein to rats has been wéll proved by numerous investigators, however the blood protein treated by H3PO4 showed wonderfully higher nutritive value than milk casein, as well as the fishmeal. This new chemical treatment of blood protein was brought about through auther's research. (Reg. Patent Off.)
We conducted the nutrition survey on the war-stricken-families, who lived in the apartment houses which were reconstructed from Japanese military baracks. In this group, there were many undernutritives suffered from the shock of war damage and economic unrest. 1t was observed, by this survey, that their nntrition intake was the 40-70 per cent of the necessary quantity.
