Oat bran lowers serum lipid concentrations in healthy and hyperlipidemic subjects. To determine the effects of a ready-to-eat oat-bran cereal on lipid concentrations, we fed control (corn flakes) and oat-bran cereal diets for 2 wk to 12 men with undesirably high serum total-cholesterol concentrations. Subjects were randomly assigned to one of the two diets upon admission to the metabolic ward. After completing the first diet, subjects completed 2 wk on the alternate diet. Intakes of carbohydrate, protein, fat, and cholesterol were virtually identical on the two diets. The oat-bran cereal provided 25 g oat bran/d. The oat-bran cereal diet compared with the corn flakes diet lowered serum total-cholesterol and serum LDL-cholesterol concentrations significantly by 5.4% (p less than 0.05) and 8.5% (p less than 0.025), respectively. Final body weights on each of the diets were similar. Ready-to-eat oat-bran cereal provides a practical means to incorporate soluble fiber into the diet to lower serum cholesterol.
燕麦麸可降低健康人群和高脂血症患者的血脂浓度。为了确定即食燕麦麸谷物对血脂浓度的影响，我们让12名血清总胆固醇浓度过高的男性食用对照饮食（玉米片）和燕麦麸谷物饮食，为期2周。受试者进入代谢病房后被随机分配到两种饮食中的一种。完成第一种饮食后，受试者再进行2周的另一种饮食。两种饮食中碳水化合物、蛋白质、脂肪和胆固醇的摄入量几乎相同。燕麦麸谷物每天提供25克燕麦麸。与玉米片饮食相比，燕麦麸谷物饮食可使血清总胆固醇和血清低密度脂蛋白胆固醇浓度分别显著降低5.4%（p<0.05）和8.5%（p<0.025）。两种饮食下的最终体重相似。即食燕麦麸谷物为将可溶性纤维纳入饮食以降低血清胆固醇提供了一种实用方法。
