Purple sweet potato is a sweet potato variety with purple flesh. The purple color comes from anthocyanins, polyphenol pigments. Anthocyanins are plant compounds studied for their role in protecting cells from oxidation by free radicals. The anthocyanins in purple sweet potato are an "acylated" type, different in form from those common in fruit, and are known to keep their color well under heat and light. The Japanese food composition tables list it separately within the sweet potato group, with nearly the same energy and carbohydrate.
How to serve
Steam or boil it until soft before use. The skin is not toxic, and the skin-on potato has more fiber (raw, per 100g: 2.8g with skin, 2.2g peeled). Still, the skin is tough and hard to digest, so peeling it is the safer choice for small dogs.
