The relationship of fiber to sensory specific satiety

The objective of this study was to determine if higher fiber levels in a food contributed to greater sensory specific satiety. Thirty-two subjects tasted and rated their liking of small samples of nine foods (including the test food) before and after a test meal. Test meals consisted of 500 kcal (2092 kJ) of a soup or a muffin. Both a high-fiber (10g) and low-fiber (1g) version of a soup and a muffin were tested. High-fiber versions contained added microcrystalline cellulose. Data from the soup and muffin treatments were analyzed separately. Each of the test meals resulted in a greater decrease in liking for the food eaten versus the uneaten foods. However, there was no increase in sensory specific satiety for the high-fiber treatments versus the low-fiber treatments. There was also no main effect for gender.
