摘要

本研究目的為在低熱量飲食下，大豆糙米飯對過重停經婦女體位、體組成及血液生化值的影響。實驗分別招募大豆糙米飯組12名和控制組11名。大豆糙米飯組以一包大豆糙米飯取代午餐主食類，控制組為自由進食，實驗為期12週，在實驗前後分析其飲食，並進行體位測量、體組成分析及血液生化分析及血中大豆異黃酮濃度分析。結果分析飲食中大豆糙米飯組膳食纖維攝取為21.5 ± 6.7克，顯著高於控制組。兩組在實驗後的體重、腰臀、臀圍、腰臀比皆顯著較實驗前低。體組成分析中體脂肪百分比、腹部脂肪百分比兩組與實驗前比較也皆顯著降低，腹部與臀部脂肪百分比的比值無顯著差異。血糖、血中胰島素濃度、胰島素抗性及胰島素敏感性指標兩組皆無顯著改變。血脂質濃度方面，兩組血中三酸甘油酯濃度皆顯著下降，高密度脂蛋白膽固醇濃度顯著上升；12週與0週相比，大豆糙米飯組血中總膽固醇及低密度脂蛋白膽固醇濃度顯著降低，而控制組則無。大豆糙米飯組舒張壓顯著低於控制組。而大豆糙米飯組中，膳食纖維及大豆蛋白攝取改變量與體脂肪百分比及臀部脂肪百分比有顯著負相關。因此過重停經婦女在攝取大豆糙米飯，有助於改善血中總膽固醇、低密度脂蛋白膽固醇濃度及舒張壓。

Menopause-induced estrogen deficiency might increase body fat accumulation, insulin resistance and abnormal blood sugar and blood lipids. Thus, postmenopausal women have high risk of cardiovascular diseases. Some studies indicated that soy can improve the syndrome of menopause. And whole grain food can reduce blood cholesterol concentration. In present study, under 1200 Kcal diet, overweight postmenopausal women intake soybean brown rice (SBR) for 12 weeks, and assess the effects on anthropometric profile, body composition, blood profile and plasma isoflavones level. After 12 week soy brown rice intake, dietary fiber intake (21.5 ± 6.7 g) were higher than control group. BW, WC, HC, WHR were decreased in both groups. And body fat percentage and android fat percentage were also decreased in both groups. Blood glucose, insulin, HOMA-IR and QUICKI were not change during the intervention period. In SBR and control group, serum TG were decreased, and HDL-C were raised. Whereas, serum TC and LDL-C were decreased in SBR group in 12 week compared with 0 week. And DBP were significantly decreased in SBR group. Dietary fiber and soy protein intake change were significantly negative correlation with body fat percentage and gynoid fat percentage change. In conclusion, under energy restriction, soy brown rice intake can reduce serum TC, LDL-C and DBP in overweight postmenopausal women.
