So, are antioxidants to the rescue? Some say yes, and many scientific studies demonstrate the amazing ability of antioxidants to decrease free radicals in the body. One genetic study took copies of a human antioxidant gene, and inserted it into the genome of fruit flies. The result? The researchers increased the flies' life expectancy by 15-30%. Other studies show that organisms generating more free radicals have shorter life spans.

Whether motivated by altruism or money, scientists often attempt to isolate "the" compound or substance responsible for positive effects on humans. Drug companies continually try to put nature's goodness into pill form. The latest drugs all seem to mimic the properties of antioxidants, yet none has succeeded at stopping or reversing aging. And none have shown a greater effect than eating foods naturally rich in antioxidants. Sure, the antioxidants in the beets I ate last night are most likely scavenging through all the cells of my body absorbing excess free radicals. But I doubt that if I took the particular antioxidant found in beets as a pill it would have the same effect. One recent study shows that eating different types of whole fruits and whole vegetables synergistically leads to greater antioxidant activity in the body. Good old country wisdom reminds us that salubrious living includes a diet full of combinations of whole foods.

So eat your beets, load up on kale, and devour a bowl of cherries. Antioxidants are good for you, and the data show that they absorb those nasty free radicals. And for dessert? Chocolate with a glass of port wine - but only if you're over 21!
