Green Tea: Health Articles
Database - Green tea research has shown it has an effect on variety of health conditions. The ability to lower blood sugar, chelate iron and control the production of nitric oxide are all especially |
important. This ancient beverage seems custom-made to protect health and delay aging. To find how green tea benefits different organs and conditions click a specific topic from our article database below:

Anti-Inflammatory Properties of Green Tea Date: 01-01-2003 |
Green tea polyphenols are also effective anti-inflammatory agents. Chronic inflammation has been linked to serious degenerative disorders associated with aging, including cardiovascular disease, cancer, and Alzheimer's disease. An important part of the inflammatory process is the excess production of nitric oxide, which in turn leads to the production of carcinogenic nitrous compounds. Epigallocatechin gallate has been found to inhibit the enzyme nitric oxide synthase, thus reducing the production of inflammation-related NO. Tumor necrosis factor alpha also plays a pivotal part in inflammation. It has been found that green tea polyphenols downregulate the gene that causes the release of tumor necrosis factor alpha. Thus, it can be concluded that green tea reduces the inflammatory response by controlling the production of nitric oxide and tumor necrosis factor alpha.
Antioxidants in green tea may prevent and reduce the severity of rheumatoid arthritis, according to a study from CWRU's School of Medicine study published in the April 13 issue of the Proceedings of the National Academy of Sciences.
The study examined the effects of green tea polyphenols on collagen-induced arthritis in mice, which is similar to rheumatoid arthritis in humans. Polyphenols are chemicalsthat occur naturally in certain foods, including green tea, and many work as antioxidants to protect the bodyfrom oxidative stress that causes disease.
In each of three different study groups, the mice given the green tea polyphenols were significantly less likely to develop arthritis. Of the 18 mice that received the green tea, only eight (44 percent) developed arthritis. Among the 18 mice that did not receive the green tea, all but one (94 percent) developed arthritis. In addition, researchers noted that the eight arthritic mice that received the green tea polyphenols developed less severe forms of arthritis. Although there is no epidemiologic data, anecdotal evidence indicates that people in countries where green tea is consumed are far less likely to have rheumatoid arthritis, said the study's senior author, Hasan Mukhtar, professor of dermatology.
