A check of the health of residents in their twenties and thirties in Nagano Prefecture's rural communities indicates that the rate of hypertensives and the incidence of cholesterolemia were low in those age groups. There were signs that the prevalence of obesity is somewhat high among males but low among females. Virtually no incidence of anemia was observed among men but the incidence was fairly high among women. The number of persons with hepatic dysfunction was relatively large among men. In terms of the intake of nutrients, there were not a few men for whom the meals were imbalanced, and the intake of alcoholic beverages was high.
It is necessary that women should refrain from taking in confectionary and taken in fishmeat, meat, milk, egg, soybeans and other proteins. In Nagano Prefecture's rural communities, there remain signs that the intake of salt is high even in young generation, so that it is important to take measures for the prevention of hypertension.
