This study was conducted to analyze the effect of isoflavone intake on prevention of chronic disease in middle and old aged man. In this study we used FFQ (Food frequency questionnaire) and the isoflavone intake level of the subjects was 25.10 mg per day. We divided the subjects into three group -high, medium, low isoflavone intake level- and investigated the relation among isoflavone intake level and clinical/anthropometric characteristics. The intake of isoflavone was inversely related with the body fat in male subjects. And we also divided the subjects into 2 groups with normal and abnormal clinical/anthropometric risk factor. The isoflavone intake level of the abnormal group with high TG, high WHR and high body fat was lower than the normal group. The main food source of isoflavone was soybean curd, bean sprout, soybean paste, soybean and soy milk, and we also investigated the relation between frequency of soybean food and anthropometric and clinical variables. The frequencies of soybean curd, soybean paste, soybean broth, soy milk, bean sprouts, peanuts, soybean and dambuk as well as intake of isoflavone were inversely correlated with some anthropometric and clinical variables such as blood pressure, TG, BMI, % body fat, and waist-hip ratio, whereas positively correlated with HDL cholesterol, muscle mass and bone density. We suggest that high consumption of soy products and isoflavone is associated with decreased blood lipid and body fat in middle and old aged man and might be useful for prevention cardiovascular diseases. From this study, we obtained valuable basic information on recommended isoflavone intake level and guidelines for the prevention of some chronic diseases/health problems.
