My concern is the risk
of goitrogens in consuming large amounts of daily cruciferous vegetables in a raw condition, and I think there's enough evidence — mechanistic, animal, and human (both controlled and case reports)-- to suggest this is a bit of a concern.
Personally I believe that there is a dietary etiology, that is, some type of
goitrogen in the diet.
Don't Eat Raw Cruciferous Vegetables — Cruciferous vegetables like: broccoli, cauliflower, brussel sprouts, kale, collard greens, bok choy and cabbage
contain goitrogens which is a chemical that suppresses the function of the thyroid gland by disrupting and blocking the enzyme that lets your thyroid use the iodine in your body to make the thyroid hormone.
DIM is the concentrated extract of cruciferous vegetables which can act
as goitrogens which basically means that they block the uptake of iodine, iodine being one of the nutrients that's required to make thyroid hormone.
Avoid eating them in large quantities raw (such as in green smoothies or juice), as cooking decreases
goitrogen content by 30 %.
Maca root is very rich with fiber and it contains
goitrogens which might have effect thyroid gland and is very difficult for our stomachs to digest.
Soy contains substances
called goitrogens which are potent anti-thyroid compounds that can lead to endocrine disruption and thyroid disorders.
Many people are concerned about the natural occurring
goitrogens found in dark leafy greens and cruciferous vegetables however no human study has ever shown that consuming cruciferous vegetables can induce hypothyroidism.
One of the last paragraphs says «most people with Hashimotos should be able to eat
most goitrogens, even in their raw state.»
In addition, this group
avoided goitrogens (compounds that interfere with thyroid function), legumes, eggs, dairy products, and gluten.
I have hypothyroidism, or a slow thyroid, so I try my best to avoid raw
goitrogens like cruciferous vegetables and soy.
It's important to know about the role of
goitrogens for thyroid patients trying to lose weight.
These foods include rapeseed (used to make canola oil); the Brassica vegetables (cabbage, Brussel sprouts, broccoli, Chinese vegetables such as Bok choy, etc, and cauliflower), all which contain
natural goitrogens, chemicals that cause the thyroid gland to enlarge by interfering with thyroid hormone synthesis.
Goitrogens do block iodine uptake in the body but cooking vegetables and continuing to eat sea vegetables allow for the thyroid to have all the iodine it needs to thrive.
Goitrogens block your Thyroid from taking in Iodine, which causes Thyroid disruption and affects various aspects of PCOS.
Raw Goitrogens: Goitrogenic foods include broccoli, peanuts, soybean, cabbage, spinach, kale, Brussels sprouts, cauliflower, kohlrabi, turnips, radishes, rutabaga, millet and watercress.
If these veggies should be cooked to
neutralize goitrogens and then the water DISCARDED, shouldn't we not use them in soups, or cook them first, then add to soup?
Women are particularly vulnerable to soy phytoestrogens and isoflavones as they are
potent goitrogens leading to impaired thyroid health, fatigue and infertility
Steaming
decreases goitrogen content by 30 %, boiling and keeping the water by 65 %, and boiling and discarding the water by 90 %.
Be especially careful about raw juicing - some of the most popular ingredients are also thyroid -
slowing goitrogens, and juicing concentrates them in large quantities.
Scratching eggs, dairy, nuts and seeds off my list, along
with goitrogen vegetables, wouldn't leave much.
Bloating I find only gets bad when I happen to eat nightshades, gluten, and some of your
general goitrogens like kale and broccoli.
Soy has been linked to the development of autoimmune
thyroiditis Goitrogens are substances that suppress the thyroid gland by interfering with thyroid hormone production.
Those involved in animal husbandry have known for quite some time that it is a bad idea to forage their animals on cruciferous vegetables; unless low -
goitrogen strains have been selected for grazing.
Boiling cabbage for just five minutes results in a 35 percent loss of
goitrogen activity; thereafter, each additional five minutes results in another five to ten percent loss.
Goitrogens work by preventing your thyroid from getting the necessary amount of iodine.
Glucosinolates are not actually goitrogenic themselves but are precursors to the
active goitrogens and to other toxins.15
This is especially beneficial for anyone with a thyroid condition
because goitrogens can diminish our body's production of thyroid hormones by blocking the thyroid's iodine uptake.
Since the thyroid is over stimulated eating foods that are high in
goitrogens helps slow down the hyperactivity.
And for goodness sake, don't eat broccoli raw — it can be very difficult to digest raw (read: gas and bloating), and it contains thyroid -
suppressing goitrogens that are deactivated when cooked.
