We know that drinking tea (in moderation!) Is excellent for your health. Thus, several studies have already shown the interest of green tea against superbugs, cognitive decline and even certain pathologies (such as rheumatoid arthritis); black tea, meanwhile, would be a good ally against overweight, bone decalcification and ovarian cancer.
According to a new study by the University of California – Irvine (in the United States), black tea and green tea are also excellent antihypertensives, which means that they help lower blood pressure.
Antioxidants that “relax” blood vessels
How it works ? American researchers (who published their work in the specialized journal Cellular Physiology and Biochemistry) explain that tea, whether green or black, contains flavonoids – and in particular epicatechin gallate and epigallocatechin gallate.
These molecules (which are natural antioxidants) would be able to activate a specific protein: KCNQ5. Located in the wall of our blood vessels, this protein would have the effect of reducing cellular excitability and relaxing the veins and arteries …
To prevent high blood pressure, what if we had tea? A little warning: according to a survey carried out by the association 60 million consumers in 2017, tea bags often contain pesticides. The best is therefore to buy in bulk (at the supermarket or organic grocery store) … by regularly varying the pleasures.
