A new study from Japan found that drinking green tea may be beneficial to the body's main artery and could help prevent its stretching or bloating, also known as abdominal aortic aneurysm. Scientists from Kyoto found that rats that were given green tea polyphenols were less likely to develop the condition. They also experienced less inflammation and more elastin production, making the artery more elastic and less prone to rupture. Abdominal aortic aneurysms eventually rupture and lead to death in 50% of the cases. They are also very hard to detect, since patients do not exhibit any outside symptoms. There are currently no pharmacological treatments for the condition that occurs more than 3 million times in the US each year, making this discovery especially significant.
