Effect of Fiber Composite-enriched Breads on Glycemic Responses
Effect of Fiber Composite-enriched Breads on Glycemic Responses
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.

 samples 5 minutes apart, they ate a portion of one of the breads containing 50g available
 carbohydrate and had further blood samples at 15, 30, 45, 60,90 and 120 min after starting to
 eat. After each blood sample also rated their feelings of satiety on a 7-point scale from
 extremely hungry to extremely full.
