Effects of Coffee and Tea on Arthritis

Excessive coffee drinking could increase your risk of developing rheumatoid arthritis (RA). But most people won't need to worry. You'd need to drink 11 or more cups of coffee per day. At that consumption rate, you are 15 times as likely to get RA. This is according to one Finnish study that monitored 6,800 people.

If you're concerned about arthritis, you should switch to tea. Studies have only been performed on mice, but the results are encouraging. Again, it's the polyphenols that seem to prevent the onset of disease. Mice were given either green tea or water, and the mice who drank the green tea were less likely to develop arthritis and those that did, had much milder symptoms.
