Summary

Health organizations recommend fiber-rich and whole-grain foods for healthy diets due to their physiological beneficial effects on human health. But, little information is available between these 2 food categories, i.e. fiber added to foods versus fiber naturally present in foods. The present study investigated the effect of enriching white wheat flour with wheat bran at 2 levels (15 and 30%) to produce 15% fiber-rich bread (15FRB) and 30% fiber-rich bread (30FRB) and compared them with white bread (WB) and whole-grain bread (WGB) in terms of bread quality, palatability, satiety, and glycemic response. Ten healthy subjects were studied on 4 separate days with each subject testing all 4 types of bread. On each test day subjects came to the test center after an overnight fast. After 2 fasting finger-prick blood samples, they ate a portion of one of the breads containing 50g available carbohydrate and had further blood samples at intervals over 2 hours. They also rated their feelings of satiety fasting and at intervals over 2 hours.
