Struggling to manage high blood pressure or hypertension? Eating dark chocolate, grapes, or drinking tea might help, according to a new study.
Researchers from the University of Surrey, UK, found that naturally occurring compounds called flavan-3-ols found in cocoa, tea, apples, and grapes may improve blood pressure and the health of blood vessels.
The research, published in the European Journal of Preventive Cardiology, analyzed data from 145 randomized controlled studies. It found that regular consumption of flavan-3-ols can lead to reductions in blood pressure, particularly in individuals with elevated or high readings.
In some cases, the average blood pressure-lowering effects were comparable to those seen with certain medications, the researchers noted.
“The findings are encouraging for those looking for accessible ways to manage their blood pressure and support their heart health through enjoyable dietary changes,” said lead author Professor Christian Heiss, Professor of Cardiovascular Medicine at the University of Surrey.
“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,” he added.
Flavan-3-ols were also shown to improve the function of the endothelium, the inner lining of blood vessels, which plays a crucial role in overall cardiovascular health. Notably, this improvement occurred independently of blood pressure changes, suggesting broader circulatory benefits.
“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,” Heiss emphasized.
Hypertension, or high blood pressure, remains a major global health issue, affecting an estimated 1.28 billion adults worldwide. This common yet dangerous condition can lead to strokes, heart attacks, heart failure, kidney damage, and a range of other serious health complications.
Experts recommend lifestyle changes such as eating a healthier diet, quitting tobacco, and engaging in regular physical activity to help manage and reduce high blood pressure.-IANS
