The sunflower gets more attention than its edible progeny, sunflower seeds. Y et, these black-striped, tear drop-shaped shells housing grayish seeds are amazing in their own right. Naturally rich in heart-healthy polyunsaturated oils, sunflower seeds are very high in the powerful antioxidant, vitamin E -- a 1/4-cup serving provides over 90 percent of the Daily Value (based on 2,000 calories/day.) These nutty seeds also provide protein, B vitamins and important minerals, such as manganese, magnesium and selenium. And that's not all -- sunflower seeds are one of the best sources of phytosterols, a compound known to lower blood cholesterol levels.
