I've had to experiment with tightening my food choices over the last year, after an ongoing battle with chronic tendinitis in my shoulder. As much as I'd like it not to be true, foods that I thought I could get away with? Corn and rice here and there, ample mayo and commercial salad dressings? Well, let's just say I don't get away with them anymore.
