5 Brain-Boosting Foods That Will Make You Smarter

Blueberries

This tiny but powerful berry helps protect the brain from oxidative stress and may reduce the effects of dementia. In a recent study, researchers gave a group of adults with mild cognitive impairment, a risk condition for Alzheimer’s, freeze-dried blueberry powder daily, while another group took a placebo. After 16 weeks, those who ate the blueberry powder (the equivalent of one cup of berries) had improved memory, better cognitive performance, and increased brain activity. Your everyday habits may also reduce your risk of Alzheimer’s.
