During the tests, experts led by professor of cardiology Verena Stangl (Verena Stangl) confirmed that the use of black tea helps maintain normal blood pressure and protects against hypertension.

The researchers linked this effect to the substances contained in tea called catechins. It turned out that these components contribute to the formation of nitric oxide, which in turn leads to the expansion of blood vessels.

When milk is added, the casein proteins contained therein reduce the concentration of catechins in tea, blocking its positive effect on the vessels, Stangle.

Meanwhile, tea with the addition of milk is the favorite drink of the English. According to statistics, 98% of UK residents prefer this way of brewing tea.

"The results obtained by us can serve as an explanation for the fact that tea is insufficiently effective in preventing heart disease among UK residents - and it is there that it is customary to drink tea with milk," summed up Stangle.
