Multiple randomized controlled trials have shown that kids do significantly better on executive function and memory performance tests (but not reading) in the hours immediately following the consumption of the equivalent of about one and a half cups of wild blueberries compared to placebo. In a randomized, double-blind, placebo-controlled study, researchers found that cognitive performance improved “across all measures” for kids consuming blueberries, and the more berries they had, the better. The researchers tested the equivalent of one cup and two cups of fresh blueberries, as well as a placebo, and cognitive improvements were found within hours of just one meal with the berries. Sounds like great brain food, especially for breakfast before heading off to school. Do the cognitive benefits of blueberries also translate to adults? When adding the equivalent of one daily cup of blueberries to the diets of older adults, researchers found improvements in their long-term memory and some ...
