Japanese cardiologists have proved that drinking large amounts of green tea can significantly reduce the likelihood of premature death in people who have suffered strokes and heart attacks. “Our observations show that drinking one to six cups of green tea per week reduces the chances of death for stroke and heart attack victims by 27%, while drinking seven or more cups reduces these chances by 60%. It is important to understand that green tea is usually consumed without sweeteners in Japan, while coffee is taken with milk and sugar,” said Hiroyasu Iso, a professor at Osaka University.
ISO and his colleagues monitored the health of more than 46 thousand people in Japan as part of the JACC monitoring project aimed at studying the risk factors that contributed to the development of cancer.
The participants of this initiative, whose age ranged from 40 to 79 years old, underwent regular examinations and were under constant medical supervision. Over two decades of JACC work, its members have experienced 9.2 thousand strokes, heart attacks and other serious failures in the work of the heart and blood vessels threatening human life.
Professor Iso and his colleagues used this data to assess how the diet of JACC participants affected their likelihood of dying after they had had their first stroke or heart attack. This analysis showed that the frequency of consumption of two types of drinks, green tea and coffee, greatly influenced the life expectancy of people with heart diseases and people who did not previously suffer from cardiac problems. In particular, drinking very large amounts of green tea, more than seven cups a week, reduced the chances of premature death by 60% for those Japanese who had suffered strokes or heart attacks in the past. However, tea was not so useful for people who did not suffer from heart disease; its use had almost no effect on their life expectancy.
