What affected me adversely was that my 'grassfed' meat was not actually grass fed. It was fattened with grains. As soon as I stopped eating it, my symptoms went away. If I were you, I would eat only fish for a while just to see if it is the meat that is tainted. Make sure the fish is not farmed. Also I found that sunflower products gave me cracks at the sides of my mouth. Grains are one of the main contributing factors of thyroid problems. In the book, What Doctors Don't Tell You by Lynne McTaggart, she says that most tests are unreliable at best. Paleobest, Susan
