Some members did not drink black tea in any respect, however for the reason that knowledge got here from the UK, there additionally have been loads of individuals who drank it commonly — and a few who drank as much as 10 cups a day, stated lead examine creator Maki Inoue-Choi, an epidemiologist on the Nationwide Most cancers Institute within the US.
The Biobank adopted up about 10 years after the unique survey, and researchers discovered that individuals who drank two or extra cups of tea every day within the interim have been much less more likely to have died from causes akin to heart problems, ischemic coronary heart illness and stroke, in line with the examine.

What concerning the milk and sugar?
For a lot of tea drinkers, the method of creating their tea is essential.
What temperature does the water have to be? Do you are taking it black? Do you add milk? Sugar? How a lot?

Folks should not depend on the outcomes from a single examine for these sorts of modifications, she stated, and extra analysis is required to spherical out the findings.
“This examine doesn’t show that tea consumption reduces mortality, but it surely does counsel that if you’re at the moment consuming tea — and particularly black tea, which was the tea kind of selection within the UK — you may proceed to take action,” Sesso stated.
