Antioxidants in Green Tea Help Rheumatoid
According to a study on mice from Case Western Reserve University's School of Medicine, antioxidants in green tea may protect from rheumatoid arthritis and reduce the severity of the symptoms. The study was published in the "Proceedings of the National Academy of Sciences."
Antioxidants in green tea, known as polyphenols, may protect the body from the oxidative stress that causes the disease. Oxidative stress is caused by free radicals, which are like chemical “bullets”. Antioxidants are like “bullet-proof vests”. Some of the polyphenols in green tea possess much more potent antioxidant activity than more well-known antioxidants like vitamin C and vitamin E.
The polyphenols were
given to mice with a type of arthritis similar to rheumatoid in humans. Of the
18 mice that were given the green tea extract, only eight (44%) developed
arthritis. The mice that received green tea polyphenolsbut got arthritis, had a less severe form of
arthritis. All but one of the mice getting the green tea-extract (94%)
developed arthritis. The extract given to the mice was an equivalent dosage to
that of a human consuming four cups of green tea each day.
