Is It Safe to Eat Goitrogens if I Have Hashimoto’s?


Should you eat Goitrogens if you have Hashimoto’s?

A myth surrounding thyroid health is that goitrogens, substances found in cruciferous vegetables like cabbage, broccoli, cauliflower, bok choy, kale and turnips, suppress thyroid function.


Goitrogens have the ability to block iodine absorption, which is critical for thyroid function.  Low iodine was a concern in the 1950’s when iodine deficiency was a major concern, but iodine deficiency is now a thing of the past. 


In fact, excess iodine is a common problem now!  Excess iodine can result in overproduction of hydrogen peroxide and cause oxidative damage to the thyroid gland.


The Verdict?


Cruciferous vegetables do contain goitrogens, but it is unlikely your thyroid condition is due to low iodine and therefore normal consumption of goitrogens would not worsen your thyroid function.  In fact, they have the ability to upregulate detox pathways and protect against thyroid damage which can be extremely beneficial!


The perfect way to detox this summer is with a refreshing smoothie.
