For a healthy thyroid, knowing what foods to avoid is just as important as knowing what to eat. Some foods can make your thyroid work less well. This guide will tell you about three types of foods that might not be good for your thyroid. If you have thyroid problems, or want to keep your thyroid healthy, it's smart to be careful with these foods.
Eating the right foods and avoiding others can help your thyroid work better, which is good for your overall health. Let's look at thyroid what foods to avoid to keep your thyroid working its best.
1. Gluten
This limitation primarily applies to people with celiac disease or gluten intolerance. Research from 2021 suggests a significant connection between celiac disease and autoimmune thyroid conditions like Hashimoto's thyroiditis and Graves' disease.
This relationship, known as the thyroid-gut-axis, indicates that gut microorganisms can influence the immune system, nutrient absorption, and thyroid function. While it's uncertain if a gluten-free diet alone can treat thyroid disease, those diagnosed with celiac disease should strictly avoid gluten to manage their symptoms effectively.
2. Processed Foods
Increasing your intake of salty, processed foods in an attempt to consume more iodine is not advisable. Manufacturers rarely use iodized salt in their products, meaning you may consume excess sodium without the benefits of iodine. High sodium intake can lead to health issues such as high blood pressure and heart disease.
3. Fast Food
Like processed foods, fast food chains are not required to use iodized salt. The American Thyroid Association (ATA) recommends avoiding restaurant foods as it's difficult to determine which establishments use iodized salt.
A study by the United States Department of Agriculture (USDA) found that fast food hamburger patties contain less iodine than non-fast food ground beef patties. Specifically, a fast food hamburger patty contained 3.3 mcg of iodine per 100g, while a non-fast food ground beef patty contained 8 mcg of iodine per 100g.
