Top Worst Foods for an Underactive Thyroid

Top Worst Foods for an Underactive Thyroid

The thyroid gland as a metabolic powerhouse directly regulates your metabolism and has a huge impact on your ability to lose weight. Decreased thyroid function makes gaining weight easy and losing weight nearly impossible. When the thyroid gland “engine” has trouble running, every process in the body suffers. The concomitant reduction in metabolic rate is a tremendous factor in weight‐loss.

Certain foods contain goitrogens and should be avoided if you have an underactive thyroid. Goitrogens are substances that disrupt the production of thyroid hormones by interfering with iodine uptake in the thyroid gland.

Foods to Avoid for Underactive Thyroid

White Bread

White bread does not contain significant nutritional value and for some people can contribute to difficulties with insulin resistance and hormonal problems.

Caffeine

Examples include, but are not limited to, coffee, soft drinks, hot cocoa, chocolate and some herbal teas. All of these delicious comfort foods and drinks will depress proper thyroid function and make your underactive thyroid symptoms worse.

Broccoli

Don’t eat this raw or cooked. Broccoli is considered a goitrogenic food, which means that consuming broccoli can increase the likelihood that you’ll develop a goiter somewhere on your body. This would be due to decreased thyroid hormone production.

Other goitrogenic foods: cabbage, rutabagas, coleslaw, sauerkraut, soybeans, kale, white turnips, horseradish, walnuts, peaches.

Peanuts

Yes, they are salty, crunchy and delicious, but they aren’t the best snack choice for someone with an underactive thyroid as they interfere with the production of thyroid hormones.

Fluoride

This is found in toothpaste and drinking water that comes from the tap. Fluoride essentially blocks iodine receptors in the thyroid gland which causes reduced iodine‐containing hormone production.

Chlorine

Not only for pools, it is found in pretty much everyone’s drinking water that comes directly from the tap. Like fluoride, chlorine also blocks iodine receptors in the thyroid gland, causing reduced iodine‐containing hormone production. So drink plenty of distilled or purified water.

Soy

Soybeans are off limits, as they have an anti‐nutrient that contains a chemical which reacts with iodine. Since iodine is critical to make the thyroid hormone, this food should be avoided if you have an underactive thyroid. Soy milk, soy flour, and tofu are also foods to add to the do not eat list.

Garlic

It may keep vampires away and it’s great in spaghetti sauce, however, garlic also reduces iodine uptake in the body.

White Flour

In the same family as white breads, this is a food that can, for some people, contribute to difficulties with insulin resistance and hormonal problems. White flour is a refined and over‐processed food and has little, if any, nutritional value at all.

Eliminating these foods from your diet and you’ll begin the path to returning your thyroid function to normal and begin to make weight loss an easier thing to do.
