Blueberries

Anthocyanins give blueberries their colour and drive most of the claims. Randomised trials report modest improvements in blood pressure, vascular function and some cognitive measures, which is more than most individual fruits can show. The trials are small, run for weeks rather than years, measure surrogate outcomes, and a large share are funded by growers.

How this list was built

We searched Europe PMC for English-language papers published since 2010 whose title contains “blueberry” or “blueberries”, kept meta-analyses, systematic reviews, trials and observational studies, because a diet or exposure like this cannot be randomised for long and its outcome evidence lives in cohorts, then ranked them by study design first, then recency and citations. Retracted papers are removed.
