Sweet potatoes belong to the Morning Glory family. They are one of the oldest vegetables in the world. They are truly a nutritional superstar; they are rated the number one nutritious vegetable by the Center for Science in the Public Interest. There are two common types of sweet potato: dry (yellow-fleshed) and moist (orange-fleshed). The orange-fleshed potatoes are known as “yams”, which is a mistake since true yams are large root vegetables that predominantly grow in Africa and Asia.
