Sweet Potato
Also known as: yam
A starchy root vegetable used as a wholesome carbohydrate in many premium and grain-free foods.
What it actually is
The tuberous root of the sweet potato plant (Ipomoea batatas). Different from a true yam. Cooked in kibble, dehydrated in raw toppers, or fed fresh.
Why it's used in dog food
Provides slow-release carbs, fibre, beta-carotene (vitamin A precursor), potassium, and vitamin C. A cleaner alternative to grains or peas in grain-free formulas.
A bit of history
Native to Central and South America, cultivated for at least 5000 years. Entered pet food in the mid-2000s as the grain-free movement looked for grain replacements that weren't peas or potato.
