If you are an athlete... you do! Your sweat contains powerful minerals and vitamins that keep your body competing at an optimal level. When you sweat them all out... what is left?
No big deal, you say? Let me share with you a piece of information my friends. I f we are not replacing all that is lost we will, over time, break down. The bone density, the ligaments, the soft pliable bursa that cushions our bones during movement, will break down. Arthritis is not genetic. Any "-itis" is the body telling us that there is inflammation that needs to be discovered and dealt with.
Continue asking your doctor "why". There is ALWAYS a root cause for any inflammation. You may not like it, and quite frankly your doctor probably doesn't know. The poor medical business doesn't allow them the time to figure it out let alone treat it with pure, clean unaltered food and nutrients. So if your doctor doesn't know, visit a Dr. of Naturopathic medicine. 9 times out of 10 the root cause will be found.
