Your thyroid is a small, butterfly-shaped gland in your neck with a massive impact on your health. It produces hormones that regulate how your body uses energy, influencing nearly every organ system.
When the thyroid isn’t functioning properly, it can lead to issues like fatigue, weight changes, and digestive trouble. And what you eat plays a big role in how well your thyroid performs.
Three Foods That May Harm Your Thyroid
Certain foods can make thyroid problems worse, especially if you’re already struggling with symptoms. The main culprits? Gluten, sugar, and dairy. These ingredients can increase inflammation and interfere with thyroid function.
Gluten: Hidden in More Than You Think
Gluten is a protein found in grains like wheat, barley, and rye. It’s the reason bread holds its shape and has that chewy texture. While gluten is most commonly associated with wheat, it’s found in many unexpected packaged and processed foods. The protein gliadin—part of gluten—is especially troublesome for thyroid health.
Important Points About Gluten:
- It’s commonly found in wheat, barley, rye, and processed items.
- Gliadin, one of its proteins, is particularly disruptive.
- Cutting out gluten may support better thyroid function.
Here are some common sources of gluten to avoid:
- Wheat, barley, rye
- Regular flour and baked goods
- Spelt, farro, couscous
- Most commercial breads, snacks, pastas, cakes, and pastries
Watch out for hidden gluten in packaged sauces, salad dressings, and even condiments like ketchup. Going gluten-free can make a big difference if your thyroid is struggling.
