Abstrakt: 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. [ABSTRACT FROM AUTHOR]
