The results may not be immediate but a recent study indicates that purple grape juice has long-term health benefits and can help combat major illnesses, like heart disease and cancer.

A study at Glasgow University measured levels of antioxidants -- thought to have a protective effect against cancer -- in a range of popular juice drinks. Purple concord grape juice came out on top, with the highest levels and range of antioxidants. Incidentally, this juice has the same level of these compounds as Beaujolais red wine.

It's recommended that we add a glass of grape juice to our daily diet and count it as one of our five daily fruits and vegetables.

Researchers caution, though, that studying antioxidants in the lab is different than studying their effect in the body.

"The problem is that we don't know what happens when they enter the body and are dissolved," one researcher says. "Obviously, eating a lot of fruit and vegetables has been shown to be good for your health, but it is not known for sure which compounds are responsible for this effect."

Still, it's not a bad idea to down that glass of juice every day -- unless, of course, you are worried about sugar content like me.
