大豆乳酸飲料對成人血脂的影響
The Effects of Fermented Soymilk on Blood Lipids in Adults
中文摘要
本研究在探討大豆乳酸飲料對健康成人血脂?是否具有影響之效應。其中以抽血 之血脂值任ㄧ部分偏高者當作初步篩選合乎實驗的受試對象: 總膽固醇(TC)>
200 mg/dL 或三酸甘油酯(TG)> 150 mg/dL 或高密度脂蛋白(HDL-C)< 40 mg/dL 或低密度脂蛋白(LDL-C)> 130 mg/dL，共有 15 位，年齡 20-55 歲，性別不拘，
進行為期六週的人體實驗，實驗採自體比較的方式。實驗前兩週為調整期，須避
免服用乳酸飲料；接著六週為實驗期，每天飲用大豆乳酸飲料500 mL(分兩次，
每次250 mL)；最後兩週為排空期，避免食用乳酸性飲料。在實驗期第零週和第
六週，採取空腹八小時之血液做血脂?分析。並要求受試者於實驗期間保持穩定 之作息。結果發現，血中總膽固醇(TC)、三酸甘油酯(TG)、高密度脂蛋白膽固醇 (HDL-C)、低密度脂蛋白膽固醇(LDL-C)濃度、TC/HDL-C 和 LDL-C/HDL-C 之比 值，實驗前後無差異。而以TG 濃度為 150 mg/dL 分組後，濃度小於 150 mg/dL 之受試者，實驗前後有顯著增加(p<0.05)。若以性別來區分男女，在女性受試者 方面，實驗前後有顯著增加(p<0.05)。男性受試者方面實驗前後無任何差異，但 仍有上升趨勢。結果顯示，在本實驗中攝取大豆乳酸飲料降血脂作用並不明顯，
因此若是要以大豆乳酸飲料當作每天營養補充品仍值得商榷。
英文摘要
The objective of this study was to investigate the effects of fermented soymilk on blood lipids in adults. The subjects were fifteen healthy adults, aged 20-55 (no sex difference), whose baseline plasma concentration of total cholesterol(TC) was either higher than 200 mg/dL or triglyceride(TG) was higher than 150 mg/dL or high density lipoprotein cholesterol(HDL-C) was lower than 40 mg/dL or low density lipoprotein cholesterol(LDL-C) was higher than 100 mg/dL. During the 6-week study period, all subjects were provided with 500 mL of fermented soymilk daily (divided 2 times, each 250 mL/bottle). Fasting blood samples were collected during the 0th week and the 6th week for blood lipids analysis. All subjects maintained their usual life during the study. After the 6-week of fermented milk consumption, the results showed no significant difference in total cholesterol、triglyceride、HDL-C and LDL-C concentration；the ratio of TC/HDL-C、LDL-C/HDL-C have the same results as blood lipids. The concentration of TG in those group whose lower than 150 mg/dL was significantly increased (P<0.05). The concentration of TG in those group of women was significantly increased (P<0.05). These findings indicated that fermented soymilk consumption did not improve the concentration of blood lipids in healthy
adults.
