The evidence is "incontrovertible" and bears repeating, says Dr. Jeffrey Blumberg of Tufts University: Free radicals contribute to the onset of age-related diseases, and antioxidants neutralize free radicals.
Everyone should take a combination of antioxidants through diet and supplementation, he asserts. (There's more on supplements later in the article.) To get that antioxidant boost, Blumberg advises eating dark-colored vegetables like tomatoes, carrots, squash and spinach for carotenoids and blue and purple berries for flavonoids. Because foods contain many classes of antioxidants that work synergistically, they are the superior source of antioxidants, says Blumberg.
