Here’s more to green tea. Latest study from Japan further supports previous evidences, confirming that drinking green tea can have cardiovascular benefits.
A study conducted on elderly people from Shizuoka, revealed that regular green-tea drinkers have considerably lower levels of cardiovascular mortality, than those who rarely drank the beverage.
Etsuji Suzuki and colleagues at Okayama University, studied 12,251 individuals for six years, all of whom were questioned about frequency of green tea consumption. An inverse association was noticed between green tea consumption and all-cause and cardiovascular mortality, but not cancer mortality.
All-cause mortality was 62 percent per 1000 individual during these years, among those consuming less than one cup of green tea a day. However, the mortality rate was only 14.4 percent per 1000 people among those drinking more than 7 cups a day.
During the entire period of study, there was 76 percent reduction in comparative risk for cardiovascular mortality, associated with highest versus lowest level of green tea consumption among all participants, with men at 70 percent risk reduction, while women were at 82 percent risk reduction.
It has been noted that magnitude of risk reduction for cardiovascular mortality are larger than those seen in previous studies in Japan. The current study offers comparatively more evidence about the protective effects of green tea on cardiovascular disease mortality, resulting in significant implications for public health, the team concludes.
On the whole, about seven cups of green tea a day can help in massive reduction in risk of death from colorectal cancer and heart disease, the new study suggests.
There have already been several clinical trials that showed beneficial effects by green tea such as its antioxidant properties and favourable influence on LDL cholesterol and hypertension.
Recently scientists at the Chinese University of Hong Kong had also reported that cells of regular tea drinkers have shown younger biological age, than cells from non-tea-drinkers.
