A study found that a compound found in pomegranates improved heart function by up to 80%.

What it means

This reports on a study showing that urolithin A, a compound produced by gut bacteria after consuming pomegranates, improved heart function by up to 80% in experimental models of heart failure with preserved ejection fraction (HFpEF), a type of heart failure with limited treatment options. The improvement was seen in the heart's ability to relax, reduced scarring, and limited enlargement. The study is preclinical, not yet in humans.

Accuracy & sourcesGrounded

The claim comes from a press release by King's College London, summarized by Science Daily. The primary source is a peer-reviewed study (likely published in a journal), but the reporting is secondary. The 80% figure is from experimental models, so it is a solid claim about those models but not directly translatable to human outcomes.
