Study Shows Blueberries, Strawberries, and Acai Berries Are Good for Your Brain’s Health

Aug. 23, 2010 — Compounds found in various berries and possibly in walnuts may slow down natural aging processes in the brain, new research indicates.

What’s more, blueberries, strawberries, and acai berries may help the aging brain in a crucial but previously unrecognized way, according to a study presented at the National Meeting of the American Chemical Society in Boston.

Scientists say they have found evidence that compounds in the berries and maybe walnuts activate the brain’s natural “housekeeper” mechanism that cleans up and recycles toxic proteins, which have been linked to age-related mental decline and memory loss.

“The good news is that natural compounds called polyphenols found in fruits, vegetables and nuts have an antioxidant and anti-inflammatory effect that may protect against age-associated decline,” Shibu Poulose, PhD, a scientist with the U.S. Department of Agriculture-Agriculture Research Service’s Human Nutrition Research Center on Aging, says in a news release.

Poulose says previous research has suggested that one factor involved in aging is a steady decline in the body’s ability to protect itself against inflammation and oxidative damage, which can leave people vulnerable to degenerative brain diseases, cancer, and heart disease.

He says research he’s done in the past has shown that old laboratory rats that were fed for two months on diets containing high-antioxidant strawberry, blueberry, or blackberry extract showed a reversal of age-related declines in nerve function and behavior involving learning and memory.
