Flavonoids are a compound found in many plant-based foods including fruit, vegetables, chocolate and tea.
Previously known as vitamin P, flavonoids are high in antioxidants and can help your body fight diseases and toxins.
Berries, apples, pears and red wine are rich in a form of flavonoids called anthocyanins which have been linked to heart health.
The lead author Professor Aedin Cassidy said in a statement from Queens: “Our gut microbiome plays a key role in metabolising flavonoids to enhance their cardioprotective effects, and this study provides evidence to suggest these blood-pressure-lowering effects are achievable with simple changes to the daily diet.”
