Heart disease rates could be reduced by 10% if everyone took to drinking large amounts of tea, a study has suggested.
Researchers found sipping eight cups of black tea a day lowered blood pressure. They estimated that in the general population this would result in a
10% reduction in high blood pressure prevalence and a 7% to 10%
reduction in the risk of heart disease.
A group of 95 men and women aged 35 to 75 were given three cups of
powdered black tea solids each day for six months, or a flavour-matched
non-tea “placebo” drink. Each tea drink contained 429 milligrams of polyphenols, plant chemicals that are said to have health benefits.
A regular cup of black leaf tea contains up to 150mg of polyphenols,
so the total dose consumed by the volunteers was equivalent to 8.58
cups of tea a day. Participants had normal to high blood pressure readings at the start of the study.
