A Good Reason to Be Nuts About Walnuts

Or you have to be nuts to believe in antioxidants.

Sprinkle some walnuts on your salad this evening. Your heart will thank you.

When it comes to heart health benefits, roasted and raw walnuts rule the roost, a new study shows.

Researchers from the University of Scranton in Scranton, Pa., compared the amount of powerful antioxidants called polyphenols in nine types of roasted and raw nuts and two types of peanut butter. They also tested just how effective the antioxidants in the nuts are in regard to heart health using lab analysis.

Here are some of the effects of the killer antioxidants:

Vitamin A supplementation increases all-cause mortality risk.
β-carotene supplementation increases cardiovascular and all-cause mortality risks and does not prevent stroke.
Vitamin C supplementation does not prevent stroke.
Vitamin E supplementation increases all-cause mortality risk and does not prevent stroke.

"Nuts" to nuts, apparently.
