The objective of this study was to evaluate the effects of repeated consumption of two high-fiber diets on postprandial glucose and insulin responses. Two mixed-food breakfast meals composed predominantly of either red kidney beans or bran cereal were fed to six healthy young men. The meals provided equivalent levels of digestible carbohydrate, protein, fat, and fiber. Insulin responses measured after breakfast were lower with the bean diet than with the bran cereal diet but higher when measured after a standard lunch. No significant interactions were found between the diets and the length of the time the subjects were on the diets (days 1 vs 7). In comparison to the postprandial responses on day 1 of the diet periods, postprandial responses on day 7 showed reduced glucose and insulin responses to breakfast and reduced insulin responses to lunch. Responses to an oral glucose tolerance test were not affected by repeated consumption of these diets.
本研究的目的是评估重复食用两种高纤维饮食对餐后血糖和胰岛素反应的影响。向六名健康的年轻男性提供了两种主要由红芸豆或麸皮谷物组成的混合食物早餐。这些餐食提供了等量的可消化碳水化合物、蛋白质、脂肪和纤维。早餐后测量的胰岛素反应，食用豆类饮食时比食用麸皮谷物饮食时低，但在标准午餐后测量时则较高。未发现饮食与受试者食用饮食的时长（第1天与第7天）之间存在显著相互作用。与饮食期第1天的餐后反应相比，第7天的餐后反应显示，早餐后的血糖和胰岛素反应降低，午餐后的胰岛素反应降低。口服葡萄糖耐量试验的反应不受这些饮食重复食用的影响。
