Researchers at Kyoto University in Japan have found that abdominal aortic aneurysm developed less in the rats who drank more green tea ( Polyphenol), a major green tea component and that without treatment Abdominal Aortic Aneurysm gets ruptured and cause death 50 % of the time. Abdominal aortic aneurysms often go unnoticed because there are no symptoms until they burst,” Kenji Minakata, author of the study.
If a patient is lucky and bloating is found before rupture, it needs to be treated surgically, such as by transplanting an artificial blood vessel or inserting a stent graft. At the moment there are no pharmacological treatments,” said Minakata.
There are many health benefits of drinking green tea, it prevents cancer, cardiovascular disease, inflammation, and oxidation.
The type of polyphenol found in green tea has recently been shown to regenerate elastin, an essential protein that gives the artery its stretchy texture,” said lead author Shuji Setozaki.
“Considering that abdominal arterial aneurysms are caused by inflammation and the degradation of elastin components in the arterial wall, we thought drinking green tea may show promise for treatment,” said Setozaki.
They also saw less inflammation and more elastin production, protecting the artery from rupture.
“Japanese people have the longest lifespan in the world, and studies show that 80 per cent of the population drink green tea on a daily basis,” said study co-author Hidetoshi Masumoto.
“We believe daily intake of green tea should be considered as a new preventative strategy for abdominal aortic aneurysm; the focus of future studies will be to investigate optimal doses,” Masumoto added.
