Overview

• A meta-analysis of 145 randomized controlled trials shows flavan-3-ols, found in tea, dark chocolate, apples, and grapes, can lower blood pressure and improve endothelial function.
• The study, published in the European Journal of Preventive Cardiology, found effects comparable to some medications, particularly in individuals with high blood pressure.
• Flavan-3-ols enhance endothelial health independently of blood pressure changes, suggesting broader cardiovascular benefits.
• Researchers emphasize flavan-3-ols are not a substitute for prescribed medication but can be integrated into a balanced diet for additional heart health support.
• Further clinical trials are needed to confirm long-term effects and determine optimal intake levels of flavan-3-ols.
