Cruciferous Vegetables Like Broccoli and Cauliflower 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.
People worried about broccoli and other vegetables in the brassica family can safely consume them as they do not cause hypothyroidism or goiter, according to research.
It's not good for thyroid as cruiciferous vegetables such as broccoli interfere with how your thyroid uses iodine.
Foods that have been identified as goitrogenic include cruciferous vegetables such as bok choy, broccoli, brussels sprouts, cabbage, canola, cauliflower, Chinese cabbage, coy sum, collard greens, horseradish, kai-lan, kale, kohlrabi, mizuna, mustard greens, radishes, rapeseed, rapini, rutabagas, and turnips.
Goitrin is an active goitrogen present in plants of Rutabaga, turnip and Brassicae seeds. However, cooking destroys the enzyme responsible for activation of progoitrin to goitrin thus negating its anti-thyroidal potency.
That said, kale, broccoli, and other goitrogens (with the exception of soy and canola) are wonderful greens and foods that help our bodies to detoxify! Remember, most cruciferous vegetables and goitrogen-containing foods are safe for those with Hashimoto's.
Cook Your Kale
The goitrogenic properties of kale become dramatically lessened when kale — or any other cruciferous vegetable — is cooked.
Cook goitrogenic vegetables: Steaming, cooking, or fermenting can reduce the levels of goitrogens. 1 If you like fresh spinach or kale in smoothies, try blanching the veggies and then storing them in the freezer for later use.
Broccoli and other cruciferous vegetables like cauliflower, kale and cabbage are not inherently “bad” for the thyroid – but they may need to be limited – or at least thoroughly cooked – by people with goiter or hypothyroidism.
Cruciferous vegetables, such as kale, Brussels sprouts, radishes, and cauliflower. Also known as goitrogenic foods (foods that can help lower thyroid hormone production), they may inhibit your thyroid gland's ability to process iodine and produce thyroid hormones—potentially easing symptoms of hyperthyroidism.
Carrots are an excellent side dish for those with hypothyroidism as they are an excellent source of vitamin A which supports thyroid function.
Cruciferous vegetables – Vegetables such as broccoli, cabbage, kale and Brussels sprouts can inhibit the production of thyroid hormone. This is especially common in those who have an iodine deficiency. Digesting these vegetables can block the ability to absorb iodine, which is needed for normal thyroid function.
“Cooking cruciferous vegetables lessens their goitrogenic properties,” says Rustveld. “It reduces the effect of goitrogens on the thyroid, so they don't cause any problem” in normal quantities. But you don't have to overcook your veggies until they're mushy; normal cooking or steaming should do the trick.
The enzymes required for production of goitrogens in the plant are destroyed by cooking. Goitrogens are also lost through leaching into cooking water.
ANSWER: Although you may find many claims about foods you should and shouldn't eat to ensure thyroid health, in general there are no specific foods you must avoid if you have hypothyroidism — including kale and spinach.
Medicinal mushrooms have shown to be beneficial to thyroid gland health, by helping to restore balance to the related hormones and cells (known as cytotoxic T cells). Chaga can help to reduce thyroid antibodies, increase natural killer cell response and activate immune pathways.
A: Generally, the more nutrient-rich the diet, the better for thyroid sufferers. White potatoes are highly nutrient-dense in their cleanest, most natural form. Potatoes provide several essential minerals that support the thyroid, including Vitamin C, B6, potassium, magnesium, iron, and iodine.
Some non-goitrogenic fruits to eat include mangoes, citrus fruits, blueberries, dark-skinned grapes, pomegranates, guavas, cherries, apricots, apples, pineapples, and kiwis.
Destroy that — sulforaphane can't form. A study by Jeffery that compared boiling, microwaving, and steaming found that steaming broccoli for up to five minutes was the best way to retain its myrosinase. Boiling and microwaving broccoli for one minute or less destroyed the majority of the enzyme.
Cruciferous vegetables, namely broccoli, cauliflower, cabbage, brussels sprouts, mustard greens, turnips, and kale are often not prescribed to thyroid patients as they are believed to interfere with thyroid function.
