Could This Popular Drink Lower Your BP reading?
Resveratrol in Drinks like Red Wine
HIGH blood pressure could be lowered by a molecule in a certain popular beverage, a new study has claimed. Should those with the condition try to lower their bp reading by enjoying the drink?
High blood pressure could be lowered by red wine, a recent study published in the medical journal Circulation revealed. A molecule found in red wine causes a drop in high blood pressure. Resveratrol is a compound found in the skin of certain fruits, such as grapes, that acts as self-defense against insects, bacteria, and fungi. It is also found in peanuts. The compound has long been touted as a panacea to several diseases including cancer, dementia, and heart and circulatory diseases but these claims are mooted.
In the study, mice with induced high blood pressure of 320mg/kg were fed resveratrol for 15 days.
Compared with mice eating a normal diet, the blood pressure of mice fed resveratrol in high quantities experienced a considerable drop in their blood pressure.
The finding offers hope that resveratrol could someday play a role in developing a new class of high blood pressure drugs.
The study is far from conclusive because they did not experiment on human subjects.
Commenting on the finding, Associate Medical Director Professor Metin Avkiran of the British Heart Foundation said: “Unfortunately, this isn’t the all-clear to open a bottle of merlot. To get the human equivalent dose of resveratrol used here, you’d need to drink an impossible amount of red wine every day.”
According to Prof Roger Corder, Emeritus Professor of Experimental Therapeutics, Queen Mary University of London, it would be the equivalent of consuming more than 3000 liters of wine.
It is a significant finding nonetheless, as Avkiran explained: “This study reveals the surprising way in which resveratrol works and opens up the possibility of new blood pressure drugs which work in a similar way. The findings bring us a step closer to tackling this ‘silent killer’ which puts people at risk of having a devastating stroke or heart attack.”
