The research, published in the Journal of Agricultural and Food Chemistry, found that participants who drank blueberry juice showed significant improvement on learning and memory tests. “These findings are encouraging and suggest that consistent supplementation with blueberries may offer an approach to forestall or mitigate neurodegeneration,” said the authors of the report. more …
