Sweet potatoes are only very distantly related to potatoes. They are part of the Convolvulaceae (Convolvulus) family of plants, like the flower morning glory, and grow as the starchy tubers of low growing, vine-like plants.

They are believed to have originated in South and Central America, and there is evidence that they were used as a food source thousands of years ago. It is believed that they were later taken to the Pacific islands, becoming an important part of the cuisine of the region, including Japan and the Philippines, and of the Maoris in New Zealand.

Although we tend to mainly import the types of sweet potato with orange flesh into the UK, there are many different varieties grown, including the purplish-red ones with a creamier coloured flesh (Kumara), which are imported from New Zealand and are slightly starchier and less sweet.

Sweet potatoes are particularly rich in carotenes, including beta carotene, which our bodies convert into vitamin A—important for normal vision. They are classified as a vegetable, so an 80 gram serving, however it is cooked, would count as one of your 5 a day.
