Abstract
The relationship of dietary intakes to subsequent development of coronary heart disease (CHD) during a 6-year follow-up period was investigated in 7705 men of Japanese ancestry, ages 45 to 68 and living in Hawaii. Data on the intakes of calories and nutrients were obtained by 24-hr diet recall interviews at the base-line examination. An index for ingestion of traditional Japanese diet (Japanese diet score) was also calculated for each man. The men who subsequently developed myocardial infarction or died of CHD generally ate less than those who remained free of CHD, with statistically significant differences for total calories, total carbohydrate, complex carbohydrate or starch, simple carbohydrate other than sucrose, vegetable protein, alcohol, and Japanese diet score. However, when other major risk factors for CHD were taken into account, the negative association with CHD remained statistically significant only for alcohol and, to a lesser extent, total carbohydrate intakes. The lower total caloric intakes in CHD cases, largely due to decreased alcohol and carbohydrate intakes, could not be accounted for by either under-reporting of food consumption among obese men or diminished physical activity in CHD cases.
