Sweet potatoes are an excellent source of vitamin A (in the form of beta-carotene). They are also a very good source of vitamin C, manganese, copper, pantothenic acid, and vitamin B6. Additionally, they are a good source of potassium, dietary fiber, niacin, vitamin B1, vitamin B2, and phosphorus. Be sure to add these wonderful naturally sweet vegetables to your meals throughout the year.

Sweet potatoes are native to Central and South America and are one of the oldest vegetables known to man. There is often much confusion between sweet potatoes and yams. They are completely different foods, belonging to different plant families.

There are different varieties of sweet potatoes which are orange, yellow, pink, white and deep purple in color. Sweet potatoes should be stored in a cool, dark and well ventilated place, where they will keep fresh for up to ten days.

Choose sweet potatoes that are firm and do not have any cracks, bruises or soft spots. Avoid those that are displayed in the refrigerated section of the produce department since cold temperature negatively alters their taste.  

If you purchase organically grown sweet potatoes, you can eat the entire tuber, flesh and skin. Yet, if you buy conventionally grown ones, you should peel them before eating since sometimes the skin is treated with dye or wax; if preparing the sweet potato whole, just peel it after cooking.

As the flesh of sweet potatoes will darken upon contact with the air, you should cook them immediately after peeling and/or cutting them. If this is not possible, to prevent oxidation, keep them in a bowl covered completely with water until you are ready to cook them.
