High blood pressure? Dark chocolate, tea may help, says study

A groundbreaking study from the University of Surrey reveals that common foods like dark chocolate, tea, and grapes could help manage high blood pressure naturally. Researchers discovered that flavan-3-ols, naturally occurring compounds in these foods, can significantly reduce blood pressure readings and improve cardiovascular health. The study analyzed 145 randomized controlled trials and found dietary changes could potentially rival some medication effects. While not a complete replacement for medical treatment, these findings offer an encouraging, accessible approach to heart health management.

High blood pressure? Dark chocolate, tea may help, says study
New Delhi, May 17: If you are finding it hard to control hypertension or high blood pressure then eating dark chocolate, grapes, or drinking tea may help you, according to a study.

Key Points

1

Natural compounds called flavan-3-ols can reduce blood pressure readings

2

Dietary changes may rival medication effects for hypertension management

3

Study analyzed 145 randomized controlled trials

4

Improvements seen in blood vessel function and cardiovascular health

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 our blood vessels.

The research, published in the European Journal of Preventive Cardiology, analysed data from 145 randomised controlled studies, and found that regular consumption of flavan-3-ols can lead to a reduction in blood pressure readings, particularly in people with elevated or high blood pressure.

In some cases, the average blood pressure-lowering effects were comparable to those seen with some medications, said the researchers.

"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,” Heiss added.

Flavan-3-ols were also found to improve the function of the endothelium -- the inner lining of blood vessels -- which is crucial for overall cardiovascular health.

This improvement occurred independently of blood pressure changes, suggesting a broader positive impact on the circulatory system.

"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 said.

Hypertension, or high blood pressure, is a major global health concern, affecting an estimated 1.28 billion adults worldwide.

This common, deadly condition leads to stroke, heart attack, heart failure, kidney damage, and many other health problems.

Lifestyle changes like eating a healthier diet, quitting tobacco, and being more active can help lower blood pressure.

Finally some good news! As someone with family history of BP issues, I'm happy to know our favorite chai might actually be helping. Just need to cut down on the sugar now 😅

Interesting study but we should be careful - dark chocolate is expensive in India and many can't afford it regularly. Our traditional foods like amla and tulsi also help BP control.

My grandmother always said kadha with tulsi and ginger is best for blood pressure. Now science is proving our home remedies right! Modern research + traditional knowledge = perfect combo 🙏

Good to know but I hope people don't start overdoing dark chocolate thinking it's medicine. Moderation is key - remember it still has calories and sugar. Stick to small portions!

As someone who switched from milk tea to green tea for BP, I can confirm it helps! Also walking 30 mins daily made big difference. Our busy Indian lifestyles need these simple solutions.

The study is promising but we need more research focused on Indian population. Our diet patterns and genetics are different from Western countries where most such studies happen.
