"Investigators at the University of Michigan have demonstrated that EGCG reduces the production of specific molecules that contribute to inflammation and joint damage in people with rheumatoid arthritis. The research focused on a type of cell called a synovial fibroblast, which helps to lubricate the lining of our joints. Normally, this lining keeps our joints moving smoothly and pain free. But in some rheumatic disorders, molecules like interleukin-1b stimulate synovial fibroblasts to produce other molecules that start or extend a process of joint inflammation and destruction.
Here’s where the green tea comes in. When the investigators pregrewsynovial fibroblasts in a dish, treated them with EGCG , and then stimulated them with interleukin-1b, they found a significant reduction in the production of bone-eroding molecules.
Other recent research suggests that if you have diabetes, then green tea just might be your drink—at least if you're a rat. Researchers at the Karolinska Institute in Sweden compared the effects of EGCG with those of the antidiabetes drug Avandia in rats with diabetes. EGCG improved the animals' glucose levels as well as the amount of insulin they made in response to a glucose load. EGCGwasn ’t as potent as Avandia , but it did have some of the same beneficial effects."
What about the practical use however? How much green tea can we really hope to drink in a day?
On average I'd say to aim for at least 2-4 cups of green tea a day.
Why? is it backed by some amount of research?
Nope but it's real world.
People don't really care that they need to be getting X amount of a nutrient in their body daily. With a job, family and life it's hard.
However it's very easy to replace the 2-4 cups of coffee or tea a day with green tea. You don't need to go out of your way to add it.
My biggest suggestion is to either replace your current drink with green tea or buy the pills and take them. Either way it pays to start adding green tea into your life.
