SO the legends go. Here's a good article about the Brassica or Cole Family of veggies and what's up with the rumors. Evidently you would need to eat 1-2 pounds of kale, broccoli, cabbage, Brussels, etc., every day to mess with the thyroid.

I had a pretty bad case of hypothyroid, and probably due to the interferon that i was on for 11 months. I am now on np thyroid 90mg.
Mayo Clinic has a good article on Hashimoto's hypothyroid.

I may have experienced some thyroid interference on the Harvoni, as I gained 10 pounds on treatment. I quit taking Harvoni in mid May, and have finally lost the weight 6 months later. I lost it in the last 6 weeks. I was thinking about getting my thyroid checked, but without any income until later this month, I had to take matters into my own hands. I fasted a couple of days, then began to drink tea and kombucha all day and not eat until dinner most days, unless I got hungry, then I would have a smoothie green drink for lunch.
It's working well for me. I'm actually not hungry in the morning when I get up, so having some jasmine or assam tea with nut milk is fine. I make 5-6 cups of tea and drink it while I go about my day, then for dinner have a green salad with homemade sauerkraut and some thick stew or stirfry etc.
I made 8 gallons of sauerkraut this summer and fall, from homegrown green cabbages and onions. I made one gallon adding a pound of ripe red bell peppers, and added onions to every batch as they help the fermentation and add probiotics. Nothing quite like fresh homemade sauerkraut, so healthy.
I was so tired but my thyroid levels kept coming back okay.
Then one day I was getting labs done for the new treatments and my thyroid levels were so high, they gave me too high of a dose of Synthyroid. I had a bad case of hypothyroidism (no one would listen to me) and finally now I take 75mg a day Synthroid brand name.
I will try generic later on again in the year. My energy levels really improved - shocking the difference it made. Wish I could eat Kale, but tummy does not like it at all......Pains....
