ResumenGrape pomace (GP) is a polyphenols (PP) and dietary fiber (DF) rich material. Although its composition is well known, its physiological effects and bioavailability are poorly understood. Male Wistar rats were fed a standard diet supplemented with 10% GP over an eight-week period. The GP-fed rats showed higher fresh and dry stool weights and increased fat, protein and mineral excretion in feces as compared to the control group. Sixty-eight percent of soluble PP were absorbed in the gastrointestinal tract, while almost all of (99%) of insoluble PP were excreted undegraded in feces improving the high bulking capacity of dietary fiber. These results could be taken into account in potential applications of this by-product as a food ingredient.
