Has anyone else read the Anthony William books? There are 3 - Medical Medium, Life Changing Foods and Thyroid Healing. He claims that the root cause for so called autoimmune diseases including thyroid problems, is NOT the body turning on itself, but our immune system fighting a virus. The virus theory is unrecognised by current medial communities, but I feel his information is worthy of consideration. The virus can lay dormant usually in our organs (not blood) and when stress and trauma come into our lives, the immune system is suppressed and the virus comes out to cause havoc for us. There are many different strains of the virus (EBV) and they can mutate and multiply over years and generations. Fascinating information for anyone motivated to try something different to regain their health.
