Cruciferous vegetables, such as broccoli and cabbage, are full of fiber and other nutrients, but they may interfere with the production of thyroid hormone if you have an iodine deficiency. So if you do, it’s a good idea to limit your intake of Brussels sprouts, cabbage, cauliflower, kale, turnips, and bok choy, because research suggests digesting these vegetables may block the thyroid's ability to utilize iodine, which is essential for normal thyroid function.
A pituitary injury may result after brain surgery or the blood supply to the brain has decreased. When the pituitary gland is injured, hypothyroidism results in low TSH blood levels because the thyroid gland is no longer stimulated by the pituitary TSH. Usually, hypothyroidism from pituitary gland injury occurs in together with other hormone deficiencies, since the pituitary regulates other processes such as growth, reproduction, and adrenal function.
Choose foods that offer nutritional support for your thyroid. The production of thyroid hormones requires iodine and omega-3 fatty acids; converting the inactive T4 to the active T3 requires selenium; and both the binding of T3 to the receptor on the nucleus and switching it on require vitamins A and D, as well as zinc. You will find these nutrients in a whole-food, clean, organic diet. To get therapeutic levels of these nutrients, please use the supplement protocol in strategy 4.
Whether you take these minerals in a multivitamin or alone, calcium and iron supplements may counteract the medication you take to treat your underactive thyroid. These supplements may affect your ability to absorb levothyroxine, the synthetic thyroid hormone found in medications such as Synthroid and Levothroid, according to the Mayo Clinic. “There’s a very strict way to take thyroid medication,” Blum says. You take it the same way every day, at least one hour before food and never with calcium, iron or other minerals. Blum recommends taking your thyroid medication as soon as you wake up and consuming the mineral supplements with food at dinnertime or before bed.
If you have been diagnosed with both hypothyroidism and iodine deficiency, there are some things you can do to make these vegetables less harmful. Cooking them can reduce the effect that cruciferous vegetables have on the thyroid gland, and limiting your intake of these (cooked) vegetables to 5 ounces a day may help as well, since that amount appears to have no adverse effect on thyroid function.
