Survey on Nofu-disease was carried out simultaneously with the investigation of nutrient intakes on 860 adult farmers of 365 households dwelling in 9 areas in Miyagi Prefecture. The nutrient intakes of the groups, in which Nofu-disease occurred rarely, were all superior in animal proteins, fats, calcium and vitamins but were inferior in total amounts of protein and carbohydrates. Kinds of foodstuff taken by the same groups were rich in animal foods (such as marine products, meat, eggs, milk and milk products), seaweeds and vegetables but were poor in grains, potatoes. candies and oils. It could be pointed out that frequent occurrences of Nofu-disease were relating to amounts of nutrient intakes and kinds of foodstuff. So, the most fundamental policy preventing Nofu-disease was believed to improve the balance of nutrient intakes.
From the fact that adult diseases bring the highest death rate to the inhabitants in Yamagata Prefecture and essential hypertension is a major cause of these deaths today, the investigation of NaCl intake of the rural inhabitants concerning hypertension and nutrition was performed. At the same time, training of the propellent members for the betterment of dietary living was attempted. The results obtained are the following. I. An average salt intake of all the household members was 23.0gr a day, which was 1.7 times greater than the desirable quantity. II. Eighty five per cent of the households had salt over intake. III. Sources of 9.5gr of the average 23.0gr daily salt intake were soy and bean paste. IV. All the households with one or more hypertensive family indicated the higher salt intake than those without hypertensive family. V. High salt intake was commonly observed within the areas where nutritional unbalance was evident. VI. Higher NaCl concentrations were demonstrated with the bean pastes and salted pickles examined.
