Abstract
Citrus pectin (15 g/day) was added for 3 weeks to metabolically controlled diets in nine subjects. Pectin was consumed with fruit and sugar as a gel in divided doses with meals. Plasma cholesterol concentrations were reduced by a mean of 13% (P less than 0.001). Fecal fat excretion increased by 44% (P less than 0.001); neutral steroids by 17% (P less than 0.001) and fecal bile acids by 33% (P less than 0.02). Plasma triglyceride levels did not change.
摘要
在9名受试者的代谢控制饮食中添加柑橘果胶（每天15克），持续3周。果胶与水果和糖混合成凝胶状，分剂量随餐食用。血浆胆固醇浓度平均降低了13%（P<0.001）。粪便脂肪排泄增加了44%（P<0.001）；中性类固醇增加了17%（P<0.001），粪便胆汁酸增加了33%（P<0.02）。血浆甘油三酯水平没有变化。
