We can't find evidence that holds up here. Proponents are reasoning from mechanism or analogy rather than direct human data, and the most credible skeptics raise objections we can't dismiss.
so forth a and will compete with iodine at the level of the thyroid and that is the collateral damage of these plant molecules
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
the glucosinolates for instance they are scavengers of iodine they are called goitrogens if you eat enough broccoli Sprouts you will become you can easily become iodine deficient
collards brussels sprouts and some russian kale contain sufficient goitrin to potentially decrease iodine uptake by the thyroid
isothiocyanates like goitrin clearly found in brussels sprouts inhibit the absorption of iodine and level the thyroid this to me is a good example of a net negative compound that has not been clearly shown to have a net positive benefit in humans
there are levels of other isothiocyanates other than sulforaphane like goitrin that can significantly inhibit iodine uptake at the thyroid
goitrin is another isothiocyanate found in things like uh brussels sprouts or chard and in levels that most people consume uh in one salad or easily on a daily basis they can affect radioactive iodine uptake at the level of the thyroid
there are levels of other isothiocyanates other than sulforaphane like goitrin that can significantly inhibit ionic uptake at the thyroid
the most goitrogenic substance in these Foods appears to be a compound called goitrin goiter is the enlargement of the thyroid gland that happens when we become hypothyroid due to inadequate amounts of iodine in the human diet or these compounds in Plants robbing us of the ability to absorb these things but this paper is suggesting that in amounts commonly consumed by humans there is sufficient amount of goitrin to significantly affect the iodine uptake at the level of the thyroid
Kale mustard cauliflower. It has compounds in it called isothiocyanates, which are goitrogens. They block the absorption of iodine. And I would rather use all of the bioavailable iodine I'm getting from my animal foods and dairy to make the hormones that control my biology, give me healthy libido, healthy metabolism. So I'm not looking to tank my thyroid, guys. I don't think it's worth it.
