About
Sweet potato (Ipomoea batatas L.) is a starchy root vegetable widely cultivated and consumed globally, valued for its dietary carbohydrates, fibre, vitamins (especially beta-carotene and vitamin C), and health-promoting phytochemicals including anthocyanins and polyphenols. It is used as a whole food ingredient in both its raw and processed forms across cuisines worldwide.
Safety summary
Sweet potato is broadly safe for the general adult population with a long history of dietary use and no regulatory restrictions. It contains moderate levels of oxalates, which may be a concern for individuals with kidney disease or a history of calcium oxalate kidney stones. No acceptable daily intake (ADI) is established, as it is a whole food rather than a food additive.
