[Stomach cancer mortality and nutrition intake in northern Japan--especially on relation to sodium chloride].

There is a big difference on the stomach cancer (SC) mortality between the north-western and the north-eastern parts of Honshu (mainland of Japan) although not much differences on cerebrovascular disease (CVD) mortality can be observed between these two areas while both of these diseases are said to be related to high-salted diets. The relation between diet and age-adjusted mortality of SC and CVD in northern Honshu was examined here, based on the results of the nutrition survey carried out by prefecture office (1971-87, 6 prefectures, total of 18 data sets). The results are summarized as follows: 1. There are no significant differences on salt intake between the north-western and the north-eastern parts of Honshu. 2. Intake of milk and dairy products is negatively related to SC. 3. Intake of animal protein is negatively related to CVD.
