I get a newsletter from in my inbox regularly and today's issue concerns me personally as well as my sister, because of the thyroid and gluten:

Here is an excerpt from it, and you can read the whole article on their website at

The connection between thyroid health, soy and gluten:

Some studies have shown that the isoflavones in soybeans can decrease thyroid hormone output by blocking the enzyme responsible for adding iodine to thyroid hormone. This means if you have low iodine in the body, the soy isoflavone may be taking what iodine you do have, leaving an inadequate amount for thyroid hormone production. The good news is, if you have sufficient iodine in your body, eating soy will most likely not be a problem. And I’ve seen soy help so many women with menopausal symptoms that it would be a shame not to consider it as an option.

Soy isn’t the only goitrogenic (meaning food or chemical that can interrupt thyroid function) food out there. The isothiocyanates found in the Brassica family of vegetables — broccoli, cauliflower, cabbage, Brussels sprouts, and so on — can reduce thyroid hormone in the same way.

Goitrogenic compounds have also been found in very small amounts in numerous other foods — from peaches and peanuts to strawberries and spinach! But, again, if you get enough iodine in your diet, as well as other micronutrients essential to thyroid function, I would not recommend cutting these healthy foods out. Simply pair these foods with the iodine-rich and micronutrient-rich foods listed in the chart above, or consider steaming them to counter the negative effects.

On the other hand, gluten is one food that I would recommend avoiding if you have a thyroid condition. There is a strong connection between celiac disease, gluten intolerance, and autoimmune thyroid issues, and many of my patients find that when they remove gluten-containing foods, they feel much better and notice less of an impact on their thyroid. For more information on any of the above, see my article on goitrogens and thyroid health.

Also, some important news about Rest: Your thyroid deserves a break — sit and enjoy!

This is perhaps one of the most overlooked pieces of advice in our modern lives: sit and enjoy your food! As women in today’s world, we are expected to do and be so many things that eating while standing at your kitchen counter, while driving, or while seated at your computer seems like the norm. But as you may have read in my article on hypothyroidism in menopause, the thyroid is very sensitive to stress. Give your mind, your body, and your thyroid a break by sitting in a comfortable space while you eat. Enjoy your meals in peace with friends and family, and talk, laugh, and let the nutrition you consume feed your thyroid, too. You deserve this break, and your body will thank you for it!

hope you find this useful,
