Flavanol-rich Foods like Tea and Berries May Lower Blood Pressure
A study involving over 25,000 people in the UK showed a significant inverse association between flavanol intake and blood pressure. Researchers objectively measured flavanol intake using nutritional biomarkers instead of participants reporting their diet. Their findings suggest that if the general population ate a healthier diet with more flavanols (present in tea and some fruits, especially berries), there could be an overall reduction in heart disease.
High blood pressure is a leading disease risk factor globally, and cardiovascular disease (CVD) is a main cause of death. Therefore, the primary prevention of CVD remains of utmost importance, and changes in dietary factors have an important role. Accumulating evidence from dietary intervention studies shows that the intake of flavan-3-ols improves vascular function in healthy adults. Flavan-3-ols are a major class of dietary bioactives, belonging to the group of polyphenolics, commonly found in tea, pome fruits, berries, cocoa-derived products and nuts.
