About Sweet Potato

Sweet potato functions in many grain-free and limited-ingredient pet food formulas as a grain-alternative carbohydrate base that also brings along fiber and beta-carotene.

Sweet potato is used in pet foods as a digestible carbohydrate and source of soluble fiber, vitamins (notably beta‑carotene), minerals and antioxidants, often helping with stool quality and serving as a binder or energy ingredient. It is generally well tolerated by dogs and can support gut health, but because cats poorly convert beta‑carotene to vitamin A and require preformed vitamin A from animal sources, sweet potato is not a substitute for meat-based nutrients; its relatively high carbohydrate content also means portion control is advised for overweight or diabetic pets and it should be cooked for best digestibility.

Derived from: Cooked sweet potato root (Ipomoea batatas), used as flour, flakes, or whole cooked pieces
Primary role: Digestible carbohydrate and binder, source of soluble and insoluble fiber and beta-carotene

Why it's used

Sweet potato supplies both soluble and insoluble fiber, and its fermentable (largely soluble) fraction is broken down in the colon into short-chain fatty acids, along with beta-carotene, and functions as a binding, energy-contributing carbohydrate in grain-free and limited-ingredient formulas. It's commonly discussed alongside stool quality and gut microbiome support, though most of the supporting fiber research in dogs and cats is on fiber sources broadly rather than sweet potato in isolation.

Common concerns

FDA's grain-free diet and canine DCM investigation The FDA's investigation into a possible link between certain diets and non-hereditary dilated cardiomyopathy (DCM) in dogs looked at grain-free diets containing peas, lentils, other pulses, and potatoes (including sweet potatoes) as prominent ingredients. Of reported case diets, the FDA found peas and/or lentils in about 93 percent and potatoes/sweet potatoes in about 42 percent, meaning legumes were the more consistently implicated ingredient category. The FDA stated the potential association is a complex scientific issue likely involving multiple factors, ended routine public updates in December 2022, and has not established that any specific ingredient causes DCM.
Cats' inability to use beta-carotene as a vitamin A source Published research (Journal of Nutrition) documents that cats absorb beta-carotene but do not convert it to vitamin A, unlike dogs and other omnivores. This means sweet potato's beta-carotene content does not supply usable vitamin A for cats, who require preformed vitamin A from animal-source ingredients.
Carbohydrate load for overweight or diabetic pets Because sweet potato is a starch-based ingredient, sources discussing its use in pet food note that portion awareness is relevant for pets managing weight or blood glucose, consistent with general guidance around carbohydrate-dense ingredients.
