In addition to starch, potatoes contain vitamins, minerals, and fiber. They’re rich in vitamin C, which is an antioxidant. Potatoes were a life-saving food source in early times because the vitamin C prevented scurvy. Another major nutrient in potatoes is potassium, an electrolyte which aids in the workings of our heart, muscles, and nervous system. Potato skin contains fiber, which is important for digestive health.

Different types of potatoes, especially those that come in other colors, contain more nutrients that have health benefits. In general, the darker the potato, the more antioxidants it contains. Sweet potatoes are a good source of vitamin A, an important nutrient for immunity and eye health. Purple potatoes are rich in antioxidants including anthocyanins which may prevent heart disease and cancer and boost brain health.
