Goitrogenic vegetables, which are cruciferous foods, such as kales and broccoli, are considered bad for thyroid function. Goitrogenic is a name derived from goiter. Goiter refers to a swollen thyroid. Goitrogenic foods affect thyroid function in different ways.
Back to goitrogenic vegetables, they affect iodine intake by the thyroid gland. Iodine deficiency was considered the primary cause of hypothyroidism. Therefore, it was common belief that kales, broccoli, soy and other cruciferous vegetables cause thyroiditis and goiter. But modern medicine has proven this wrong.
Hypothyroidism treatment involved iodine and tyrosine supplements. These nutrients are vital in the synthesis of thyroid hormone. The iodine deficiency was solved by increasing iodine amounts in table salt. After some time, no one lacked iodine. However, that did not stop hypothyroidism cases. Hashimoto’s disease became prevalent.
The thing with iodine is that, lack of it causes hypothyroidism and too much of it causes hypothyroidism in Hashimoto’s. People require iodine in very precise doses. So adding iodine amounts solved hypothyroidism caused by iodine deficiency but increased cases of Hashimoto’s. Prevalence of Hashimoto’s is growing with each passing day. So iodine and goitrogenic vegetables are not responsible.
One should note that hypothyroidism caused by iodine deficiency requires that they stop taking goitrogenic foods as they inhibit the absorption of iodine. However, these vegetables are not an issue if the hypothyroidism is caused by Hashimoto’s. Actually, iodine in excess is linked to the increased Hashimoto’s prevalence. Hashimoto’s patients should take these vegetables. But they should ensure they are taking organic vegetables as non-organic vegetables have toxins as a result of the use of pesticides.
A legitimate concern is with soy. Soy is a goitrogenic food that interferes with thyroid function, by interfering with the Thyroid Peroxidase (TPO). TPO is an essential enzyme that facilitates the transfer of iodine to the thyroid hormones.
All hope is not lost
Inarguably, Hashimoto’s disease is a serious thyroid disease. Fortunately, it can be reversed. Unfortunately, most people do not know they have the conditions. Individuals with the symptoms discussed should go for testing.
