If you have hyperthyroidism, you should be aware of the foods that can contribute to your condition and avoid them. Here, we discuss some of the foods to avoid if you have hyperthyroidism.

Seafood

Seafood is the most important dietary source of iodine and should be the first food to consider when it comes to hyperthyroidism. Crab, lobster, oysters, mussels, and clams are all high in iodine and should be avoided if you have hyperthyroidism. Other seafood such as shrimp, cod, salmon, and tuna should be eaten in moderation.

Dairy Products

Dairy products like milk, cheese, and yogurt are high in iodine and should be avoided if you have hyperthyroidism. The iodine content of dairy products varies depending on the type of animal and the type of feed given to the animal. For example, dairy products from cows that are fed iodine-fortified feed are higher in iodine than those from cows that are not fed iodine-fortified feed.

Egg Yolks

Egg yolks are another source of iodine and should be avoided if you have hyperthyroidism. Egg whites are low in iodine and can be eaten in moderation.

Iodized Salt

Iodized salt is a common source of iodine and should be avoided if you have hyperthyroidism. Instead, you should consider using sea salt or Himalayan pink salt, both of which are low in iodine.

Iodized Water

Iodized water is another source of iodine and should be avoided if you have hyperthyroidism. If you live in an area where the water is iodized, consider using a water filter to remove the iodine.

Some Food Colorings

Some food colorings, such as those containing carmine, are high in iodine and should be avoided if you have hyperthyroidism. Instead, you should look for food colorings that are free of iodine, such as those made from fruits and vegetables.

If you have hyperthyroidism, it’s important to be aware of the foods that can worsen your condition. Seafood, dairy products, egg yolks, iodized salt, iodized water, and some food colorings are all sources of iodine and should be avoided if you have hyperthyroidism.
