Researchers have been studying green tea’s effect on everything from cholesterol to the risk of definite cancers, with mixed results thus far. Green tea encloses antioxidant chemicals that may assist to deflect the cell damage that can lead to disease.
For the recent study, published in the American Journal of Clinical Nutrition, researchers determined to observe the question of whether green tea drinkers have a lower risk of infirmity and disability as they grow older.
Yasutake Tomata of the Tohoku University Graduate School of Medicine and his colleagues followed almost 14,000 adults aged 65 or older than three years.
They found those who drank the most green tea were the least expected to develop functional disability, or struggle with daily activities or basic needs, like dressing or bathing.
Particularly, almost 13 per cent of adults who drank below a cup of green tea per day became functionally disabled, compared with just more than 7 per cent of people who drank at least five cups a day.
Tomata and his colleagues wrote, “Green tea consumption is significantly associated with a lower risk of an incident functional disability, even after adjustment for possible confounding factors.” The study did not verify that green tea alone kept people agile as they grew older.
Green-tea lovers usually had healthier diets, comprising more fish, vegetables and fruit, with more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more generally active and have more friends and family to trust.
However, in spite of those factors accounted for, green tea itself was united to a lower disability risk, the researchers said.
People who drank as a minimum five cups a day was one-third less expected to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 per cent lesser risk.
While it’s not obvious how green tea might recommend a buffer against disability, Tomata’s team did note that one latest study found green tea extracts emerge to boost leg muscle strength in older women.
Although green tea and its extracts are considered safe in small amounts, they do enclose caffeine and small amounts of vitamin K, which means it could hamper with drugs that prevent blood clotting.
According to a Japanese study, aged adults who frequently drink green tea benefits may stay more lively and autonomous than their peers over time…
