Naturally occurring compounds called flavan-3-ols found in some food and drink may improve blood pressure and the health of blood vessels, according to a new study
A daily cuppa or a small chunk of dark chocolate could do wonders for your heart, according to new research from the University of Surrey. The study found that naturally occurring compounds known as flavan-3-ols – found in cocoa, tea, apples and grapes – may enhance blood pressure and the health of blood vessels.
The research, published in the European Journal of Preventive Cardiology, scrutinised data from 145 randomised controlled studies. It discovered that regular consumption of flavan-3-ols can lead to a reduction in blood pressure readings.
This was particularly true in people with raised or high blood pressure. In some instances, the average blood pressure-lowering effects were comparable to those seen with some medications.
Flavan-3-ols were also found to improve the function of the endothelium – the inner lining of blood vessels. This is vital for overall cardiovascular health.
This improvement occurred independently of blood pressure changes, suggesting a broader positive impact on the circulatory system. Professor Christian Heiss, lead-author of the study and Professor of Cardiovascular Medicine at the University of Surrey, said the results were “promising”.
He said: “The findings are encouraging for those looking for accessible ways to manage their blood pressure and support their heart health through enjoyable dietary changes. Incorporating small amounts of commonly consumed foods like tea, apples, dark chocolate, or cocoa powder into a daily balanced diet could provide beneficial amounts of flavan-3-ols.
“While not a replacement for prescribed medications or medical advice, including more flavan-3-ol-rich foods in a daily routine could be a valuable addition to a healthy lifestyle, especially for those with higher blood pressure. These are findings that, although promising, require ongoing investigation.”
