Soy-rich foods and soybeans contain phytoestrogens that may prevent the enzyme that generates thyroid hormones from functioning. A study conducted on women who took soy supplements concluded that their chance of developing hyperthyroidism was three times higher, explains Healthline.

The lack of enough iodine can lead to some types of hyperthyroidism. Under such circumstances eating foods rich in iodine or using iodized salt can be helpful. However, too much iodine can have a negative effect because it can affect the activity of the thyroid gland, according to Healthline.

Doctors recommend diets rich in fiber. However, too much fiber can affect the way the body absorbs thyroid medication, says Healthline.

As a goitrogen, kale does not let the thyroid get enough iodine. A person getting enough iodine should not have problems with kale. However, if a person has low iodine levels, kale can lead to thyroid problems. Other vegetables that can lead to a similar problem include Brussels sprouts, cabbage, cauliflower and broccoli, explains WebMD.

Organ meats such as liver, kidneys and heart can lead to an increase in lipoic acid. Excess lipoic acid can affect the way the thyroid functions and have an effect on thyroid medication, says WebMD.
