Foods which you have to be careful with most revolve around soy-related products and ingredients, as well as certain cruciferous veggies, nuts and some fruits
Now luckily for the owner of this site, chocolate is NOT considered a Goitrogenic food. But here are foods that ARE:

Also included in the goitrogen category, even if mildly, are:

But, don’t panic, and there are two reasons why! Cooking does appear to help minimize or inactivate the goitrogenic compounds found in these foods, since they are heat sensitive. Also, just because you eat these foods uncooked does NOT mean you will have problems…if you remember the word “moderation”. The owner of this site eats a few strawberries in her Greek plain yogurt several mornings a week. She also enjoys spinach a few times a month (because she can’t stand most other vegetables) as well as peanuts. And with soy being added to many products, it’s hard to avoid. The key is to not eat any goitrogens excessively, pay attention to those labs for hidden soy, and use moderation.
(And now you know why those of us “in the know” cringe when we see the heavy emphasis on soy products in the supermarket, including infant soy formulas! )
Even resveratrol, found in grape skins and wine, plus peanuts, can be a problem to your thyroid if you consume too much.
There are also certain chemicals which can have a goitrogenic effect on your thyroid function. They include:
Amiodaronecarbamazepineiopanoic acidLithiumphenobarbitonephenytoinpotassium perchloratepropylthiouracilrifampinsulfadimethoxineSSRI’s like Celexa and others
Iodine and goitrogens: Dr. Brownstein states that taking more iodine will counteract eating some goitrogenic foods. And fluoride, chlorine and bromides are goitrogens too. www.iodine4health.com www.optimox.com)
