I am treating my Hashimoto's naturally through diet - no gluten, dairy, yellow corn, soy, and low sugars, plus lots of lean organic protein and veggies. My thyroid swelling is gone. I am also taking thyroid hormone because by the time I discovered this diet, my thyroid was mostly dead. Read my journal for more.
MacMillian Nelson avoided RAI and is feeling great by following the blood type diet. If you send him questions, he will be happy to share his story.
