Potatoes are underground tubers that grow on the roots of a plant called Solanum tuberosum. The world's favourite root vegetable, the potato comes in innumerable varieties. Its shapes vary from small potatoes to large and round types. Most have pale brown skins and cream or yellow flesh, but some speciality varieties are differently coloured, like the Purple Peruvian. Cooked potatoes with skin are a good source of many vitamins and minerals, such as potassium and vitamin C.
Potatoes are stuffed with phytonutrients, which are organic components of plants that are thought to promote health, according to the USDA. Phytonutrients in potatoes include carotenoids, flavonoids and caffeic acid. The vitamin C in potatoes acts as an antioxidant. These substances may prevent or delay some types of cell damage, according to the National Institutes of Health. They may also help with digestion, heart health, blood pressure and even cancer prevention.
