In reply to the discussion: The Dark Side Of Kale (And How To Eat Around It [View all]kentauros
(29,414 posts)20. In fact, what seems to be fueling the fear in this article
has nothing to do with moderation. From further down in the article content not posted:
Very high intakes of cruciferous vegetables
have been found to cause hypothyroidism (insufficient thyroid hormone) in animals (68). There has been one case report of an 88-year-old woman developing severe hypothyroidism and coma following consumption of an estimated 1.0 to 1.5 kg/day of raw bok choy for several months. Two mechanisms have been identified to explain this effect. The hydrolysis of some glucosinolates found in cruciferous vegetables (e.g., progoitrin) may yield a compound known as goitrin, which has been found to interfere with thyroid hormone synthesis. The hydrolysis of another class of glucosinolates, known as indole glucosinolates, results in the release of thiocyanate ions, which can compete with iodine for uptake by the thyroid gland. Increased exposure to thiocyanate ions from cruciferous vegetable consumption or, more commonly, from cigarette smoking, does not appear to increase the risk of hypothyroidism unless accompanied by iodine deficiency. One study in humans found that the consumption of 150 g/day (5 oz/day) of cooked Brussels sprouts for four weeks had no adverse effects on thyroid function.
(emphasis mine)
And for those that don't remember their metric conversions, 1 kilogram (kg) is 2.2 pounds!
Really now, I see nothing to worry about at all.

I love all of those vegetables, except for the brussel sprouts, and I eat them

Probably because few people have access to fresh sprouts or know how to cook them

I read this yesterday. Interesting, but I'm not sure it's applicable to most people who eat kale.

kale, chard, and spinach salads have been a big part of how I have lost 20 lbs in the last
