Pomegranates may be all the rage lately, but the health benefits of this supposedly hot new item have been available in your produce aisle all along.

With a flavor both tart and sweet, the pomegranate contains clusters of small edible seeds with juicy red fruit. Pomegranate seeds are often used in salads and cooked dishes.

Like all fruits and vegetables, pomegranates are a good source of a variety of phytochemicals, including polyphenols, which seem to provide protection against heart disease.

Studies on both mice and people show pomegranates may help prevent the process that results in LDL -- or bad -- cholesterol contributing to clogging arteries. Pomegranates may also help maintain blood flow, keeping your blood vessels healthy.

The buzz about pomegranates is based on evolving science but adding pomegranates -- either fresh or in juice form -- to your shopping list can improve variety in your diet and possibly your health.
