blueberries (and strawberries) was linked to delays in
cognitive aging by up to 2.5 years.^3 And while a recent
review found no association between general fruit intake
and dementia risk in humans, berries were found to be
associated: they protected the brain against cognitive loss.^4
How to buy and consume: Fresh blueberries are great,
but don’t be afraid to buy frozen blueberries, which are
often much cheaper (and more widely available) than fresh.
Always opt for organic. Blueberries are great in smoothies
and salads or eaten as a snack.
Pro tip: All berries are likely helpful to the brain, though
they vary in terms of the specific beneficial compounds
found in each. When you want to mix things up,
blackberries, bilberries, raspberries, and strawberries may be
used in place of blueberries.
