Gluten gluten gluten. 

If you have hypothyroidism and especially if you have Hashimoto’s, you’ve likely read or been told that you must avoid gluten. But why?

Written by Amie Hornaman, Functional Medicine Practitioner with a Masters in Clinical Nutrition.

You must avoid gluten, you must avoid gluten. I know you are so sick of hearing it by now, especially if you have autoimmune disease Hashimoto’s, but here’s the thing; as
humans we need to know the why behind our behaviours. When someone tells us what to do, our first instinctual question is… why?

In order to make a true behavioural health change we must understand, at least on some level, why we are making a change, why we are doing something that is so damn hard to do.

So, Let’s discuss!

Gluten will interfere with your thyroid functioning properly and you will gain more weight, be more tired, and lose more hair. Period.

I never said I was going to tell you what you want to hear, I’m going to tell you what you need to hear!

Now you want some details. OK let’s start with inflammation. Gluten is not tolerated by approximately 80% of all humans. I’m not talking about being Coeliac, I mean not tolerated at all. (Non-celiac gluten sensitivity to be exact)

Some call it gluten intolerance. Our bodies just weren’t cut out to process gluten so we experience inflammation, and oftentimes its not felt or experienced on a daily basis so we ignore it. However, ignorance is not bliss and this inflammation will do a few different things.

First, since conversion of T4 to T3 takes place in the liver and in the gut, eating gluten containing foods will inflame the gut lining, cause leaky gut and reduce the conversion. That equals a bad day and is the last thing you want.

We want and need that T3. T3 runs the show, gives us our metabolism and gets us out of bed in the morning. Our bodies crave it, our cells crave it, and without it, well you all know how it feels without it, you feel like garbage. Hold onto that thought for a moment…

Second, for those with Hashimoto’s or Graves’ Disease, did you know that the molecular structure of gliadin, the protein portion of gluten, closely resembles that of the thyroid gland? What does this mean for you?

When you eat gluten containing foods the gliadin enters the bloodstream via your broken down, inflamed gut lining that has been wearing down from years of eating gluten, and is then targeted for destruction by your immune system. The antibodies to gliadin also start attacking your thyroid gland. So, if you have autoimmune thyroid disease your immune system attacks your thyroid.

You have to be 100% gluten-free to prevent immune destruction of your thyroid. Unfortunately “mostly gluten-free” is not acceptable. That’s like being kind of pregnant.

You need to make a decision, what do you want more, to feel good and work a little harder at eating right or to feel like crap but get to eat what you want when you want?

The studies are in [1,2,3] and science is backing me on this…if you have ANY thyroid issue you must avoid gluten. I gave you the why, so now you have no excuse.

  1. Thank you for saying what I’ve been saying for years! No one believes me though. Sigh. People would rather eat whatever they want than be healthy. Cutting out gluten was the best thing I ever did!! It’s been 11 years. I do not miss it!
