Hopefully, this category can morph into a tool I can use and have access to from anywhere. Or possibly it needs to be a journal entry that can be done with the iTouch. I’m going to start here:
From Dr. John McDougall Forum:
(From discussion on flaxseed as thyroid hormone inhibitor)
Almost every food there is can act as a goitrogen. I contacted the USDA about soy and they sent me back an email saying that it isn’t a problem unless you are not getting enough iodine.
But they said beware of lettuces because of thiocyanates. So I looked into that and they are in just about everything. Plus the lettuce I was buying at a norther California farmers market was actually being grown down in perchlorate valley aka southern California and the perchlorate is a big problem for the thyroid.
Then I read some studies that that iodine is now considered the most common cause of hypothyroidism and that there are multiple studies showing that keeping daily intake below 100mcg will prevent and reverse hypothyroid and conversely that communities started seeing more cases of hypothyroid when iodine supplementation was started.
So I figure that you can have too much or too little iodine and that either one can be a problem depending on the rest of my diet. It’s all a balancing act.
Since I eat a lot of foods that have the thiocyanates and phytoestrogens, I don’t worry about consuming iodine, but I also don’t eat a lot of high iodine foods.
That seems to work fine. (posted by Bren)
Dr. John McDougall recommends levothyroxine.
