The potato is a root vegetable native to the Americas, a starchy tuber of the plant Solanum tuberosum, and the plant itself is a perennial in the nightshade family, Solanaceae.
Wild potato species, originating in modern-day Peru, can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated by indigenous peoples of the Americas independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Potatoes are nutrient-dense, non-fattening and have reasonable amount of calories. Include them in your regular meals so that the body receives a good supply of carbohydrates, dietary fibers and essential minerals such as copper, magnesium, and iron. In India, potatoes are probably the second-most consumed vegetables after onions.
