or are we just talking fat overeaters who try to climb and trash their tendons?
There is a lot of talk about inflamatory reactions and autoimmune-related issues being related to possible food reactions. Usually, soy and gluten are pointed out as big factors; but fortunately, there are many foods mentioned that do the opposite and are suggested to be included in your diet.
Google will provide lots of links for you; do a search and you will find many interesting hypothoses about diet's impact on your tendons and joints. I have tried following a couple of different regimens to alleviate discomfort from tendonitis and arthritis. I don't know if I believe the stuff 100%; but it doesn't do me any harm to experiment with some folks' recommondations (i.e. by removing soy from my diet for 6 months, eating more cayanne pepper to reduce inflamation, or something equally simple and straightforward) to see if there is a difference.
