The sweet potato is a starchy, sweet-tasting root vegetable. They have a thin, brown skin on the outside with coloured flesh inside – most commonly orange in colour, but other varieties are white, purple or yellow. Sweet potatoes are a rich source of fibre as well as containing an array of vitamins and minerals including iron, calcium, selenium, and they’re a good source of most of our B vitamins and vitamin C. One of the key nutritional benefits of sweet potato is that they’re high in an antioxidant known as beta-carotene, which converts to vitamin A once consumed.
