Eating berries may activate the brain's natural housekeeper for healthy aging

ScienceDaily (2010-08-24) -- Scientists report the first evidence that eating blueberries, strawberries, and acai berries may help the aging brain stay healthy in a crucial but previously unrecognized way. Their study concludes that berries, and possibly walnuts, activate the brain's natural "housekeeper" mechanism, which cleans up and recycles toxic proteins linked to age-related memory loss and other mental decline.
