15 Reasons Sweet Potato Is A Staple Food For Diabetics.

Posted on March 30, 2015 at 4:35 PM

Sweet potatoes belong to the Convolvulaceae or morning glory plant family, are dicotyledons (or “dicots” for short, with the prefix “di” referring to the fact that they have two embryonic seed leaves), and are known by the scientific name of Ipomoea batatas.



Sweet but not really a Potato:

Sweet potatoes, though resembling in appearance to yams or the common potato, belong to an entirely different food family, so when you choose sweet potatoes as a dietary root vegetable, you are getting a truly unique type of potato that is nutritionally different from other types. The skin and flesh of the sweet potato which comes in 400 odd varieties, may be almost white, cream, yellow, orange, pink, or deep purple, although white/cream and yellow-orange flesh are most common.



The intensity of the sweet potato’s yellow or orange flesh color is directly correlated to its beta-carotene content, which is referred to as “Provitamin A” as our bodies can typically produce vitamin A from it.


Purple-fleshed sweet potatoes, on the other hand, are a fantastic source of anthocyanins (especially peonidins and cyanidins) and have outstanding antioxidant activity, more than even blueberries.



History of Sweet Potato:

Sweet potatoes are native to Central and South America and have been consumed since prehistoric times (10,000 years ago). Christopher Columbus brought sweet potatoes to Europe after his first voyage to the New World in 1492. By the 16th century, they were brought to the Philippines by Spanish explorers and to Africa, India, Indonesia and southern Asia by the Portuguese. Around this same time, sweet potatoes began to be cultivated in the southern United States, where they still remain a staple food in the traditional cuisine.
