台中地區更年期婦女飲食中營養素、異黃酮素及相關食物攝取狀況之研究

The aim of this study was to evaluate the dietary intake of patients with postmenopausal symptoms. The dietary assessment was conducted on outpatients in the Department of Obstetrics and Gynecology of China Medical University Hospital during February of 2002 to May of 2003. We recruited 55 diagnostic postmenopausal patients and assessed their blood biochemistry, 24-hour dietary intake recall assessment, and 3-day dietary record. The basic laboratory data were within normal limits except for total cholesterol and low-density lipoprotein-cholesterol (LDL-c). Data of the 3-day dietary records showed that the calorie (1618±513 kcal; 108%), protein (58.9±24.1 g; 126%), and fat (61.2±28.1 g; 122%) intake levels of the volunteers were significantly higher than the 2002 Recommended Daily Intakes in Taiwan. Dietary intake levels of dietary fiber, calcium, magnesium, vitamins E, B6 were less than 2002 Recommended Daily Intakes in Taiwan. The daily isoflavone intake was 10.9 ±9.9 mg, including daidzein 4.81±4.54 mg, genistein 6.30±5.86 mg, and glycitein 0.74±0.96 mg. The major isoflavone resources were tofu, dry tofu, soy milk, and soybean sprouts. In conclusion, postmenopausal women in the Taichung area showed higher calorie, fat and protein intake and less vitamin E, calcium, and magnesium intake than the average for Taiwan. Meanwhile, the isoflavone intake of these volunteers was less than other Asian countries such as Korea, Japan, and China.
