Fiber is the portion of carbohydrate in a diet that is difficult for the digestive system to break down and use. Despite its limited digestibility, fiber does have benefits for our pets.

Fiber helps address the concern about the prevalence of obesity in pets. It is important in special diets designed for weight reduction or weight management. Fiber helps reduce caloric intake and provides pets a satisfied feeling of fullness when being fed fewer calories.

However, high-fiber diets alone will not ensure weight loss. Strict portion control is also necessary for a successful weight loss program. Work with your veterinarian to plan a weight reduction program for your pudgy pet.

The value of fiber to help prevent constipation is well known. Fiber absorbs water and lends bulk to the intestinal contents. This stimulates the movement of the intestinal tract and normalizes passage time through the bowel. Fiber sources also contribute to fecal consistency.

Sources of indigestible fiber in pet foods include rice hulls (bran), wheat bran, oat bran, soybean hulls, beet pulp, apple and tomato pomace, peanut hulls, citrus pulp, and cellulose. Pulp is the solid residue that remains after juices are extracted from fruits or vegetables; pomace refers to the pulp of the fruit.

Studies suggest that a moderate increase in dietary fiber may also be helpful in the management of diabetes mellitus. Certain forms of fiber in the diet tend to slow the absorption of sugar from the intestine, which aids in blood sugar control.

In assessing the role of fiber in a pet's diet, the old adage "more is not better" holds true. Excessive dietary fiber is associated with adverse effects such as the production of loose stools, flatulence (or gas), and increased stool volume or density. Reputable pet food manufacturers formulate diets to provide balanced nutrition with proper levels of fiber for a pet's life stage and activity level. Fed in the proper amounts, fiber is a critical component of proper nutrition and good health.
