Green tea is a common healthy drink around the world and it has been shown to reduce risk of chronic illness. Research has recently showed that this is not due to antioxidants as previously believed.
Researchers have found that green tea contains catechins belonging to a group of polyphenols that have been demonstrated to actually increase oxidative stress rather than lower it.
How is that a good thing? By increasing oxidative stress in the short term, it increases your body’s defensive capabilities. One cup a day is all that you need.
