A study from Japan raises green tea a powerful anti aging food to new and higher levels. Men and women in the study who drank 7 cups of green tea a day lowered their risk of heart disease by a whopping 75%. The study was done at the University of Japan by Etsuji Suzuki. Involved were 12,250 people and they were analyzed to estimate the various associations between green tea drinking and all cause mortality, cancer and heart disease.
This suggests that seven cups of green tea a day over time may massively reduce the risk of death from heart disease and colorectal cancer, compared to people who drank only one cup a day. This kind of disease reduction is truly amazing and the consequences could be massive. The study was followed up 5 years later and showed that the seven cup drinkers had a 55% lower risk of death by any cause making green tea a anti aging food.
The study also showed that people who drank the seven cups of green tea a day reduced their risk of colorectal cancer by 31%. This was compared to those that only drank three cups per day. Suzuki stated, “To our knowledge this is the first cohort study that shows an inverse association between green tea and colorectal cancer mortality.
The people used in this study were between the ages of 65 and 84. These results said the researchers “may be due to long term high consumption green tea”. Other research shows green tea to be a disease prevention tool in cure cancer diets.
The antioxidants in green tea are from the polyphenols and much research has shown that polyphenols will help prevent many major diseases. Green tea is extra ordinarily high in water extractable polyphenols. Black tea on the other hand has only 3% to 10%. The primary polyphenols for the scientific minded are epigallocatechin gallate (EGCG), epigallocatechin (EGC) epicatechin gallate (ECG) and epicatechin (EC).
