Nutritional intake and longevity. International comparative study.

We tried to make the relation between the state of nutritional intake and the life span of human beings clear by comparing them internationally. 1. Observing the correlation of nutrition and life span of both advanced and the other nations, the tendency is almost the same with that of the middle and low developed nations. It can be concluded that in any case the more the nutritional intake is, the more favorable influence is given upon the life span. Examining only about the advanced nations, however, it resulted that the correlations of the both are either very low or opposite to each other. It can be said that the people taking so much nutrition are having a bad influence upon the life span and death. It is especially true with the animal origin calorie and fats and oils. 2. Generally speaking, the influence of nutritional intakes upon the life span seems to change from the better or the worse at the following points. As for the total calorie it changes somewhere around 3000 kcal per capita a day, 35-40 % for the ratio of animal origin calorie, around 90g for protein, 50-60g for fats and oils. 3. Observing the relation between the two in the yearly transition of 7 nations, the intakes of total calorie, the ratio of animal origin calorie, protein, fats and oils, meat and eggs pararelled well especially with arteri-osclerotic and degenerative heart diseases both in ranking by each nation and in yearly transition. Especially with intake of meat, it traces the most alike excess of ranking.
