Why is Inulin included in pet food?

Inulin is added to pet food for two key reasons: 1) it is somewhat sweet and can be used to increase a food’s sweetness even though it is a relatively low calorie alternative to other fats or sugar and 2) it can be used as a prebiotic to aid digestion.

Common benefits or risks of Inulin

Benefits: There are many benefits of Inulin.  Inulin is a low calorie carbohydrate and fiber source with about 25% less calories than sugar and about 10-12% less calories than fat.  Inulin can increase calcium absorption and can be characterized as a prebiotic, which is a substance that feeds the healthy bacteria in the body’s intestinal system.

Risks: Too much Inulin can produce bloating, gas, and diarrhea in some people, as would most any diet with too much fiber.  We have not found any research studies related to the levels of Inulin needed to cause similar gastric distress in dogs or cats.
