Are blueberries food for the brain? Definitely yes, according to a new study revealed in the Daily Mail giving blueberry powder capsules, versus placebos. Adults with pre-dementia (MCI) had improvements in memory, back up by measured increase in brain activity when given MRI scans, compared to those on plalcebos. This is quite remarkable, given the relatively short timeframe. I eat blueberries, and drink Blueberry Active. Blueberry capsules, as given in the study, are available from CherryActive. They are certainly one of the best superfruits to eat.
