The Study
Effect of walnut consumption on markers of endothelial function in adults: A systematic review and meta‐analysis of randomized controlled trials
This study combines results from several experiments where people were randomly given walnuts or not to see how their blood vessels work. It found that eating walnuts might help blood vessels relax better, but doesn’t prove it for sure. Other signs of blood vessel health didn’t change much.

Key takeaways
Summary
Based on the study abstract and findings.
- 1A better FMD means blood vessels can relax better, which is good for heart health.
- 2The other markers didn’t change, so walnuts may only help certain aspects.
- 3Walnuts improved one blood vessel test (FMD) by 0.94%.
- 4They did not change ICAM-1, VCAM-1, or SARM levels.
