Study finds flavonoid-rich foods improve vascular health AI illustrationhow this picture was made

A meta-analysis examining flavonoid-rich foods and vascular function in healthy adults is listed on PubMed. The entry was logged 5 October 2026 ^[1]. The work appears in Food & function. It is a systematic review and meta-analysis of randomised controlled trials, with a stated total sample of 561 participants. Authors reported a statistically significant improvement in flow-mediated dilation for the flavonoid intake group compared to control. The reported mean difference was 1.58%, with 95% confidence interval 0.90 to 2.27% and P < 0.0001. Carotid-femoral pulse wave velocity also showed a statistically significant improvement in the intervention group. Reported mean difference was -0.28 m s⁻¹, with 95% confidence interval -0.52 to -0.04 m s⁻¹. The analysis returned an I² value of 75.7%.
