The Cleveland Clinic, a premier U.S. heart hospital, has recommended the sweet potato as one of the 40 most powerful foods for heart health.
Sweet potatoes are loaded with the heart-healthy antioxidants beta-carotene (the plant form of vitamin A) and anthocyanin.
Compared with a russet potato, a sweet potato has:
-- nearly as much potassium
-- a bit more vitamin C
-- a bit more fiber (if you eat the skin)
-- more than a day's worth of vitamin A (russets have no vitamin A)
-- the same number of calories (about 100 for a medium potato)
The most popular sweet potatoes in the United States are the moist, orange-fleshed garnet, jewel, and Beauregard varieties, but several others are available.
For the most part, different varieties can be used interchangeably in recipes, although the moist, orange-fleshed ones generally are a little sweeter and take a little longer to cook. Ask your local grocers which ones they sell or look for the more unusual varieties at farmer's markets.
Buying tip: The vegetable may be labeled as sweet potatoes at one grocery store and yams at the next, but officially, they're all sweet potatoes. A real yam is hard to find, unless you go to an ethnic market.

Sweet Potato Tips
We asked experts to share their tips for buying, storing, and enjoying sweet potatoes.
Pass up sweet potatoes with soft or sunken sports or sprouts, says Jason Tucker of The Sweet Potato Council of California.
Store sweet potatoes loose in a cool (55-65 degrees F), dark place. "Refrigerated sweet potatoes will develop an off-taste, a hard center, and won't be as sweet," says Sue Johnson-Langdon, executive director of the North Carolina Sweet Potato Commission.
"Leftover cooked sweet potatoes work great in recipes such as quick breads or soups," says Holly Clegg, national spokeswoman for the Louisiana Sweet Potato Commission.
Store leftover cooked sweet potatoes in a zipper-lock bag in the refrigerator or freezer, depending on how quickly you plan to use them.
Ordering at restaurants:
Be sure to check how the sweet potatoes are prepared and how large the serving is before you order, says Marsha McCulloch, M.S., R.D., Heart-Healthy Living staff dietitian. You may want to split it with a companion. Avoid toppers such as marshmallows and choose baked sweet potatoes over sweet potato fries, which restaurants often deep-fat fry.
