Is Tart Cherry good for inflammation?

The evidence points that way, though it's not yet conclusive. A systematic review and meta-analysis found tart cherry (typically Montmorency variety) supplementation modestly aids recovery from strenuous exercise, with a separate meta-analysis finding benefit for endurance exercise performance specifically. That's reflected in an evidence score of 52/100 for its role in inflammation, drawn from 8 studies (5 RCTs), with an estimated impact on longevity rated limited (32/100).
