Sometimes when I over-indulge in tea I get pain in my joints and tendons, particularly black tea. I am concerned about the long-term effects on my joint and bone health. I understand green tea is anti-inflammatory so it's good for arthritis. But on the other hand, I have read black tea increases risk of arthritis. Also I know caffeine leaches some calcium from the bones, so I try to get plenty of calcium in my diet. Finally, I am slightly concerned about fluoride, which can cause joint pain through skeletal fluorosis, although I believe this is somewhat rare. I do try to drink good quality loose leaf teas to reduce the fluoride exposure.
Is the temporary pains and aches I feel from too much tea just exhaustion from the caffeine? Or perhaps a pre-existing condition worsened by the caffeine or other components in tea?
