They add tang and crunch to breads, cereals, yogurt . . . and they do a little something for your brain, too. We're talking about berries and walnuts.

Turns out that the polyphenols in walnuts and berries help quell the inflammation and oxidative stress that can injure the brain and lead to memory problems over time.

Potent Brain Protection
In fact, the polyphenols in berries and walnuts -- as well as in grape juice -- are so powerful, some research suggests they might even help reverse cognitive decline once it occurs. For example, in one study of older adults with mild dementia, the subjects performed better on memory tests after Concord grape juice was added to their diets. So sprinkle some nuts and berries on your breakfast cereal, serve it with a side of grape juice, and let brain-boost begin.
