Thyroid: Minimize Goitrogens for Optimal Metabolism + Weight

Here is a great list of foods that slow down your thyroid. They are also known as goitrogens. Isn’t that a weird word?

It’s best to avoid these foods in their raw form – lightly cooked is a better option.


Frequently, my clients say to me: “Dr. Sara, what gives? You are the Queen of Greens. Aren’t they good for my estrogen metabolism?!”

Yes, dark leafy greens and members of the Brassica family (such as cabbage, kale, spinach, chard, and Brussel sprouts) are good for making more of the good estrogens and less of the bad estrogens, but the effect is that of a sea-saw. When you help estrogen metabolism, you slow down the thyroid. If you are a fast metabolizer, you may not even notice. But if you’re like me and tend toward an unforgiving metabolism, you may just notice that your metabolism has slowed down a notch. Your weight has creeped up a bit. You may be a little more bloated or constipated. You might be slightly more fatigued…all signs of a slower thyroid.

Get a More Forgiving Metabolism

Minimize or avoid these foods if you have a thyroid issue. If you have some of these symptoms, ask your doctor for thyroid blood test, such as a TSH (Thyroid Stimulating Hormone) and a free T3 (active thyroid hormone). Extra credit for a reverse T3.

Get your thyroid on your side, working for you, not against you.

As always, let me know if you have questions or comments with your experience with goitrogens and your lovely thyroid.
