This study compared the effect of whole grain high-fiber barley, whole grain wheat and refined rice-based foods on energy intake and satiety. Forty-seven healthy subjects consumed a breakfast of hot cereal and a snack mix containing either barley, wheat, or refined rice, followed by an ad libitum smorgasbord lunch using a crossover design. Energy intake was measured at the lunch using plate waste. Hunger, fullness, desire to eat, amount of food consumed, and thirst were assessed using a modified Visual Analog Scale (VAS) before and after the breakfast, snack and lunch. Energy intake at lunch did not differ among products. There were no differences in the area under the time curve in modified VAS scores among products for any parameter. However, subjects reported significantly less hunger before lunch compared to their hunger before breakfast when consuming the barley, but there was no significant reduction in hunger before lunch after consumption of wheat or rice. In conclusion, intake of a whole grain high-fiber barley, whole grain wheat, or refined rice breakfast and snack did not decrease energy intake acutely, but consumption of whole grain high-fiber barley foods significantly decreased hunger whereas whole wheat and refined rice foods did not.
