Can Food Allergy Testing Help Hashimoto’s Hypothyroid

By Adem Lewis / in , , , , , , , , , , , , , , , /

Hey, everyone. This is Dr. Ruscio. Let’s talk about food allergy testing, and
if food allergy testing can help those with Hashimoto’s, with thyroid autoimmunity. And I’d like to thank Dr. Nick Hedberg for
making me aware of this study. I’ll put the abstract of this study up here
on the screen. This study was entitled Evaluation of Correlations
Between Food-Specific Antibodies and Clinical Aspects of Hashimoto’s Thyroiditis. So, the question here really is, is if you
have thyroid autoimmunity, which is the most common cause of hypothyroidism, might you
have higher levels of food allergies, and could a food allergy test tell you those food
allergies, and then could avoiding those foods help reduce your thyroid autoimmunity, and
thus help with the function of your thyroid and hopefully, your symptoms? According to this study, no. And let me quote a few pieces from the study. There was no significant correlation between
any of the 12 increased food-specific antibodies, including gluten, and clinically important
phenotypes such as thyroid hormone levels or thyroid antibody levels or symptoms. So essentially, what they found, to state
that more clearly, is that there was an equal elevation in healthy controls as there was
in those with thyroid autoimmunity. So, those with Hashimoto’s had some elevations
of certain food allergens, and healthy controls had certain elevations of food allergens. And here’s how the allergens skewed, in
terms of most common allergen, all the way down through the least common allergen. Milk was the most. Milk and eggs, followed then by grains, followed
then by nuts, followed then by legumes, followed then by fruits, or fruits and vegetables,
and then finally, by fish, then seafood, then meat, and then coffee and tea. So, what we see here, milk, eggs, grains,
nuts, and legumes were the most common food allergens detected. But there was no difference, meaning there
were not any more food allergies detected in those with thyroid autoimmunity. Now, what’s funny about this, and what you
may have heard me say previously is, that I don’t use food allergy testing because
we’ve figured out, meaning the scientific and dietary community at large has figured
out, what the most common food allergens are. And these are depicted in one of a handful
of readily available diets, one of which is a Paleo Diet. So, one could go on a Paleo-like diet, and
depending on the version of Paleo Diet that you do, you would be cutting out milk, maybe
eggs, definitely grains, and legumes, and potentially nuts, depending on if you do kind
of your regular Paleo or the more strict, more avoidant version of the Paleo Diet known
as the Autoimmune (or AI) Paleo Diet. And both of these are fairly easy to obtain
a food list for on the Internet, or in my book. It’s not like … If you’re not familiar
with these things, they’re not hard to find and figure out what to eat and what not to
eat. Now, here’s something that I think is important. We have evidence showing that essentially,
a Paleo-like diet was used in one clinical trial, and did show the ability to lead to
a 40 to 44% reduction in thyroid peroxidase and thyroglobulin antibodies. So, we do have documentation that avoiding
foods that are commonly known to be problematic can improve thyroid autoimmunity. But, you don’t need to do an expensive blood
test to document a food allergy to justify avoidance of the food. By the time you went to the doctor’s office
or the lab, drew the blood, waited for the results to come back, and then started your
diet, you could already be three weeks into a trial on a Paleo-like diet, and ostensibly,
feeling better. So, skip the testing. Go right to an elimination diet to see if
you feel better avoiding some of these foods. Now, it’s also important to mention that
in this same study that I mentioned a moment ago that showed the 40 to 44% reduction in
thyroid antibodies on a Paleo-like diet, there was also a suggestion that these patients
may have suffered from a degree of carbohydrate malabsorption. And now, what does that mean? It means you don’t absorb carbohydrates
well, just as the label implies. So, this opens the door to the possibility
that these Hashimoto’s patients may also do well on a lower FODMAP diet, which reduces
foods that feed bacteria. And there is a fairly impressive initial body
of data, preliminary data, showing a correlation between small intestinal bacterial overgrowth
and thyroid autoimmunity. Also, one study showing a correlation between
H. pylori and thyroid autoimmunity. But I think there’s more impressive data
looking at the association and documenting the association between small intestinal bacterial
overgrowth, SIBO, which will make you sensitive to FODMAPs, and thyroid autoimmunity. So, if all that seems like a lot, what do
you do? It’s actually not that complicated. What you want to do is heal your gut. Because if you can heal your gut and improve
the health of your gut, then you can arguably, improve the health of your thyroid. Is it a guarantee? No. But we know that the gut is very impactful
on your immune system because you do harbor the largest density of immune cells in your
entire body in the small intestine. So, if you can fix your gut, as this one study
has shown with the utilization of a Paleo-like diet, you may see a 40 to 44% reduction in
thyroid antibodies. Now, to build on that, perhaps if you go low
FODMAP, that can help you even more. And perhaps if you treated H. pylori or SIBO,
or just went through an antimicrobial protocol to help clean out any excess or imbalanced
bacteria, you may improve further yet, still. And certainly, that’s something I see in
the clinic somewhat frequently. I’ve seen that enough now, I’ve seen enough
patients who, after improving the health of their gut and treating some type of dysbiosis,
or bacterial overgrowth, some patients, and we’ve even documented some of this on a
clinical newsletter, have been able to reduce the dose of their thyroid medication, but
feel better at the same time. So, a lot here, I’m giving to you, kind
of in rapid fire. But it all comes down to this – the bottom
line in optimizing your thyroid health is improving the health of your gut. And the book that I’ve written, Healthy
Gut, Healthy You is the most comprehensive roadmap I could offer you in improving your
gut health, and it tends to improve your thyroid health. So, remember that if you’re confronted with
a decision to perform a food allergy test, I would save that money and just go right
into a dietary trial, again, my book will help you with knowing how to perform these
dietary trials. And that could again, keep money in your pocket
and get you to the end result more quickly. So, yes, there is an association between gut
health and the thyroid. But no, you don’t need to spend money on
expensive food allergy testing to obtain the benefits of the diet-gut-thyroid connection. This is Dr. Ruscio and hopefully, this information
helps you get healthy and get back to your life. Thanks.

  1. Good info. I almost paid $400 for a consult with a dr datis kharrazian affiliate from his website, it included labs. I just thought that was too much $$ bcz i have dr datis book.

  2. Dr. Ruscio, I am already on AIP and Low Fodmap diet and I reach my macros pretty well. I feel very fatigued and foggy.
