Thyroid Nutrition
Thyroid Nutrition
If you have been following me, or if you have read about my health story, you will know that I have suffered from autoimmune Hashimoto’s Thyroiditis. It caused a lot of my health problems until I began treatment and making changes in my diet. I have learned to control my symptoms and get the disease under control by diet and lifestyle. While I am more than willing to share with you what has worked for me, the truth is, everyone is different and what works for one may not really work for another.
Registered Dietitian Nicole German specializes in thyroid so I asked her to share information with us. Here are her suggestions on the basics for thyroid nutrition.

Hashimoto’s Diet: Learn the Basics
June 14, 2019 By ngerman8
The most common question I get asked is, “what should I eat?” for a Hashimoto’s Diet.
I never have a clear, exact answer since each person is so unique and has a completely different medical and social history. It takes me a good hour long session with someone to understand their background and be able to give clear and specific recommendations. However, there are a few key foods or food groups that are more likely to help or hinder the thyroid condition.
Hashimoto’s Diet
Next, what I am about to describe are generalities and should not be thought of as a diet therapy. The foods mentioned below are the foods that we currently have the most research on regarding autoimmune nutrition and thyroid nutrition. Always check with your own healthcare provider before beginning a new plan.
Foods I Avoid
Soy
Research explains that soy may interfere with thyroid hormone, and overall be likely to cause lower T3 levels in those who consume soy consistently. I generally avoid soy protein fortified foods, processed fake “meat” soy products, edamame, and tofu. In addition, soy is a food that may carry much higher levels of pesticide residues which may impact thyroid health.
Gluten
This a controversial topic. Some practitioners theorize that gluten appears similar to thyroid tissue, and the body may falsely recognize it as thyroid tissue and increase the autoimmune attack. For some, gluten may be a food that generally causes inflammation as it is a common food allergen. Other research and health experts argue that gluten deteriorates the health of the intestinal tract, and avoiding it may help improve the health of the intestinal tract, and therefore, improve an autoimmune condition. In addition, a small percentage of people who have Hashimoto’s may also have Celiac disease. So, I recommend Celiac testing before going 100% gluten free to rule this out. I highly recommend this article and video about Dr. Fasano’s point of view on gluten to learn more on the topic. Here is an article on gluten and Hashimoto’s.
I continue to avoid gluten, and it has taken my body a long time to heal after 25+ years of gluten ingestion.
What do I often tell my clients? At the least, trial a gluten free diet for 30 days. Journal and record symptoms and what you eat. Ideally, do this under the care of a Registered Dietitian who can help guide you with this. The majority of my clients report they feel significantly better and do not want to go back to eating gluten.
Added Sugar
I strive to avoid added sugar daily. I make conscious decisions. Why? Because excess sugar leads to excess inflammation. Limiting excess sugars can help promote better blood sugar balance and more optimal insulin levels which promotes longevity and lessens inflammation as well. This also helps to manage cravings and supports a healthier intestinal tract!
What counts as added sugar? Check food labels for one of these: cane sugar, anything with the word “syrup” like corn syrup and brown rice syrup, honey, maple syrup, brown sugar, agave. I continue to stevia to sweeten a few things here and there like a smoothie or a recipe.
Millet
Research has shown that millet, a type of gluten free grain, lowers thyroid hormone. Millet also does not contain much nutrition.
Foods to Use Caution With
Dairy
This is a common food allergen and/or intolerance for many people in the general population. Some have sensitivities, in particular, to the casein protein in dairy (dairy is made up of casein and whey protein). Others have lactose intolerance to some degree which can cause issues with digestion and nausea. Do you feel you are sensitive? You can get tested with MRT LEAP, or keep a food symptom journal as you eat to see if you notice a trend of increased symptoms with dairy consumption.
Many functional medicine practitioners recommend avoiding dairy for autoimmune thyroid conditions, however, I am on the fence. I do not believe that it is a must avoid. I believe it should be avoided on a case by case basis. Why? I know that I am able to tolerate dairy and still feel my best. However, I do not eat excessive amounts. And, I recommend the same for many of my clients: maximum of 2-3 servings of dairy per day, and choose high quality dairy from grass fed animals and organic varieties.
Less than 4 cups of raw cruciferous veggies daily
There is anecdotal research that more than 4 cups of raw cruciferous veggies may impact the thyroid enough to cause thyroid enlargement due to goitrogens. And, if we cook cruciferous veggies, the goitrogens are reduced. Cruciferous vegetables include brussels sprouts, kale, broccoli, cauliflower, and bok choy, for example. That being said, I highly recommend eating these veggies since they contain many amazing health benefits, but not overdoing it on the raw form.
Nuts and Seeds
The main issue here is that I find nuts and seeds can be a common allergen or food sensitivity. Or, they can be difficult to digest for those with more severe bowel disease. However, they provide excellent nutrients and excellent healthy fats and should not be avoided if there is no allergy issue. I did not discover I was extremely sensitive to almonds until I was tested! So, this is one area where you may want to test and not guess.
Foods to Eat More of
Sweet Potatoes
These days it seems everyone is on a form of a low carb diet. However, this is one starchy veggie not to skimp on as it contains loads of vitamins, minerals, great fiber, and phytochemicals that are all healthy for thyroid support. One neat fact about the sweet potato is that is is less likely to raise blood sugar as much as other refined carbohydrates like white rice!
Carrots are another excellent food to include as vitamin A in this food form may help improve thyroid levels!
Spinach
Especially organic varieties… Spinach is not a goitrogen, and contains loads of nutrients like iron which I find many women with thyroid conditions may run a little low on. This leafy green is easy to eat in salad form, cooked as a side with garlic and olive oil, and tossed into a smoothie for added nutrients.
Pineapple
Pineapple contains bromelain which is a nice enzyme that aids in digestion in our stomachs. Those of us with autoimmune thyroid conditions can get all the help we need for our digestion! Last but not least, pineapple adds a nice sweetness to meals when we are avoiding the added forms of sugars as well!
High Quality Proteins
Next, proteins like non-processed chicken (pasture raised is ideal), turkey, grass fed beef in moderation, eggs (if not sensitive), low mercury fish like salmon, and plant proteins (quinoa, sprouted legumes) provide excellent vitamins and amino acids to support thyroid function and to help maintain nice lean muscle mass to support optimal health. A Registered Dietitian can also help give you specific recommendations on how much protein you need in a day.
Thus, there are many more foods that I encourage eating, but it depends on the individual and their health history.
Avoid Extreme Low Carb Diets

Conclusion
In conclusion, this is not the end of the list or a complete guide for how to eat. However, I hope that this gives you are starting point for where to look next in your quest for optimal eating and optimal health!
