I had lots of knee pain from age 12-46 even when I wasn't fat. And also joint pain in a couple of my fingers, wrists & elbows. Removing the inflamatory foods from my diet (processed high carbs; processed vegetable oils; all grain, dairy & legume proteins) has eliminated those pains, and allergy-induced asthma and chronic sinusitis. On the rare times I indulge in these inflammatory foods, it all comes back rapidly, sometimes in as little as 30 minutes. Ganglia/inflamed bursa pop up in my previously injured or over-stressed joints and it takes 3-7 days for the pain and other ailments to dissipate after returning to clean eating.
