Here's another reason to include blueberries, strawberries and walnuts in your diet: the polyphenols these foods contain appear to be good for the brain. In fact, these micronutrients seem to reverse an age-related decline in the process by which brain cells remove and recycle biochemical debris that could interfere with brain function. Investigators with the U.S. Department of Agriculture Human Nutrition Research Center on Aging in Boston found that the polyphenols in these berries seem to help maintain the process by which specialized brain cells do their "housekeeping." Researcher Shibu Poulose, Ph.D., noted the study provides further evidence of the benefits of eating foods rich in polyphenols. In addition to berries and nuts, fruits and vegetables with deep red, orange or blue colors also pack an antioxidant punch. Dr. Poulose emphasized the importance of consuming the whole fruit and noted that frozen berries, available year round, are also good sources of polyphenols.
