Well, read this my friend: Beware of coconut/coconut oil/flour if your are hyperthyroid!! About three months ago I started pulling oil with coconut oil for twenty minutes every morning. It cleaned the plaque off my teeth and gave me fresh breath. I was so pleased. I was also from time to time baking with coconut flour, which I had never done before.... this on the recommendation of an endocrinologist whom I had consulted about my thyroid. At the time I started pulling coconut oil I was hypothyroid with a goiter. Now I am severely hyperthyroid per blood tests lasat week. As I started losing weight uncontrollably I began researching to find what elements in my diet/daily routine could cause such rapid weight loss. I found information that coconut oil can raise thyroid function 20%. So I have switched to olive oil for oil pulling and I no longer include any form of coconut in my diet. My doctor tells me I may have to have my thyroid killed with radioactive Iodine or have it surgically removed.
