"Goitrogenic foods—which interfere with thyroid function—include cruciferous veggies like broccoli, cauliflower, Brussel sprouts, kale, kohlrabi, mustard, turnips, rutabaga, and cabbage, as well as soy products and millet. Strawberries, peaches, and spinach are also somewhat goitrogenic. You don’t have to give up these foods completely (crucifers in particular have some great anti-cancer compounds), but definitely scale back on them if they’re currently a large part of your diet, especially if you already have hypothyroid symptoms." --Denice Minger
I currently eat about 600 calories of steamed vegetables (especially brussel sprouts, cauliflower, broccoli). I LOVE steamed vegetables; but is this too much? I am a 21-year old woman, 5'9", 145lbs. I'd like to get down to 135lbs (my racing weight) and veggies help a lot to scale back on calories. But if having too many of these vegetables will disrupt my thyroid function, then that's not good...any advice? Ideas? Am I overdoing it?
Unless you already have thyroid issues it shouldn't be a major problem. If you are steaming the foods it should help inactivate the goitrogenic compounds to some degree. Eating raw or juicing large amounts of these foods would pose more of a problem. That being said, mix it up and maybe not just eat mainly crucifers every day: zucchini, summer squash, and bok choy are some others you may enjoy steamed.
This is my own anecdotal experience:
I am hypothyroid, and am treated with just 1 grain of a natural porcine-based prescription (Nature-Throid). If anything, I have been consuming way more of these veggies after going Paleo (about 6 mos ago) however, I've been being treated for hypothyroidism for 2 years. I haven't noticed a change over the last 6 mos, nor has my lab work - my numbers are fantastic. Conversely, many of the nutrients found within those veggies actually support thyroid function.
Do you feel as though you are having adverse symptoms? You could get your thyroid levels checked, perhaps? Just make sure you find a functional medicine doctor who doesn't just treat numbers, but also takes into consideration your symptoms. Stop the Thyroid Madness is a fantastic website which gave me the knowledge I needed to get another opinion on my "within range" thyroid numbers.
