A randomized trial was conducted to compare effects of a diet high in monounsaturated fatty acids, enriched with avocado (AE), and a high-complex-carbohydrate diet (AHA-III) on blood lipid concentrations. Fifteen females between 37 and 58 y of age were allocated either to AE followed by AHA-III, or vice versa. Each dietary phase lasted 3 wk. Both diets were found to lower total cholesterol compared with baseline values. AE was more effective, with an 8.2% decrease (P less than 0.05) whereas AHA-III was associated with a 4.9% decrease (NS). Low-density-lipoprotein cholesterol and apolipoprotein B decreased significantly on AE but not on AHA-III (P less than 0.05). The high-density-lipoprotein (HDL) concentration did not change on AE but decreased 13.9% on AHA-III (P less than 0.01). It is concluded that AE is more effective than is AHA-III in decreasing total cholesterol, and, unlike AHA-III, it does not decrease HDL concentrations.
进行了一项随机试验，以比较富含鳄梨的单不饱和脂肪酸高饮食（AE）和高复合碳水化合物饮食（AHA-III）对血脂浓度的影响。15名年龄在37至58岁之间的女性被分配接受先AE后AHA-III的饮食，或反之。每个饮食阶段持续3周。与基线值相比，两种饮食均能降低总胆固醇。AE更有效，降低了8.2%（P<0.05），而AHA-III降低了4.9%（无统计学意义）。低密度脂蛋白胆固醇和载脂蛋白B在AE上显著降低，但在AHA-III上未降低（P<0.05）。高密度脂蛋白（HDL）浓度在AE上没有变化，但在AHA-III上降低了13.9%（P<0.01）。得出的结论是，在降低总胆固醇方面，AE比AHA-III更有效，并且与AHA-III不同，它不会降低HDL浓度。
