Glucose tolerance and lipid profiles in dogs fed different fiber diets.

Increased dietary fiber is thought to have beneficial effects on health in humans. In diabetic dogs, a beneficial effect of fiber on glycemia has been suggested, while its effect on lipid profiles in dogs has not been described. The effects of different amounts and types of fiber on glucose tolerance and lipid concentrations were evaluated and compared with those of a standard maintenance ration in 30 healthy dogs. It was concluded that increased fiber intake had no influence on glucose in healthy dogs but it may have modulated lipid homeostasis.
