The Technical Committee of the League of Nation recommended lg/kg/day as the minimum safe protein intake for an adult. The author confirmed in the previous report, that the indication of protein deficiency appeared by providing the subject with 0.8 g/kg/day of dietary protein for 12 weeks.
The author aimed to examine whether or not the previously believed protein intake of lg/kg/day can maintain the normal level of blood property and adrenocortical function. For the purpose, monks on Mt. Hiei who were taking 1.0-1.3 g/kg/day of dietary protein for long period of time were examined on their blood properties and adrenocortical function.
It was found that the blood properties are maintained at almost normal level, and the excretions of adrenocortical hormones in urine are at the lowest level in their res-pective normal range. From these results and by taking into consideration of the wide variety of digestibility of Japanese diet, it was concluded that 1.25 g/kg/day was reasonable as the safe intake for Japanese as was recommended recently by the National Resources Council in Japan.
