The current Migaku evidence database contains 2 reusable source documents for Blackcurrant Visual Performance Meta-Analysis. This answer focuses on safety, limits, and clinician-discussion contexts. - Purpose Despite equivocal human study data, anthocyanin-rich blueberries are associated with positive glycaemic effects which could benefit satiety and other cardiometabolic outcomes. [Ellis LR (2026); evidence level 2] - Conclusion Wild blueberry effects on postprandial glucose and appetite hormone responses were evident at anthocyanin doses of 300 mg and above but did not impact other outcomes in healthy adults. [Ellis LR (2026); evidence level 2] - The objective of this study was to examine the dose-dependent effects of freeze-dried wild blueberries on postprandial glucose response simultaneously with changes in satiety, blood pressure and cognitive function. [Ellis LR (2026); evidence level 2] - Across the six included studies, most consistently demonstrated a positive association between higher fruit and vegetable (FAV) intake and improved cognitive performance among adolescents and young adults. [Soans JS (2025); evidence level 3] - This review demonstrates that increased fruit and vegetable consumption is consistently linked to improved cognitive function in adolescents and young adults. [Soans JS (2025); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
