Sweet potatoes, when cooked, have a creamy texture and a sweet and sour taste, perfect for a wide variety of recipes. These tubers rich in fiber, vitamin A, C and B6, contain antioxidant and anti-inflammatory properties, which stimulate the immune system creating greater resistance to infections. Originating in South America, sweet potatoes have yellow, white and purple external colors, but their varieties go far beyond that, differing according to shape, size, sweetness and other aspects.
