Sweet Potatoes

Sweet potatoes and potatoes are not closely related and do not belong to the same family
Additionally, sweet potatoes have a much lower glycemic index compared with white potatoes - 45 compared to 75-100 - and they are richer in antioxidants than potatoes
Sweet potatoes are one of the most nutritious vegetables around - they are high in vitamin A, vitamin C and manganese as well as a good source of copper, dietary fiber, vitamin B6, potassium and iron
Purple sweet potatoes, are an excellent source of fiber and vitamins and are especially prized, for their high levels of an antioxidant known as anthocyanin which is responsible for the brilliant purple color of the flesh - it is the same pigment that gives blueberries, red grapes and red cabbage their color

The darker/brighter the color of the sweet potato the more antioxidants and the skin is as nutritious than the flesh
They can be stored in a cool dark place for about a week, however, they lose their flavor when stored in the fridge
Steaming or baking sweet potatoes can double their antioxidant value, however, boiling them reduces it
Including some fat (like avocado) when eating sweet potato significantly increases the uptake of the beta-carotene
