PHILADELPHIA (CBS) – We constantly talk about the value of red wine, but it is often at the expense of grape juice.

French researchers have looked at the issue closely and they have found the grape can help the heart.

Polyphenols in concord grape juice activates cells called endothelial cells and help them produce nitric oxide which helps protect against cardiovascular disease.
