For years now, I've heard the "experts" insist that goitrogenic vegetables are FINE as long as you cook them! I mean -- vegetables are S0-0-0-0-O good for you! It would be dangerous to restrict non-starchy vegetables (even though the paleoids snicker at those who insist that GRAINS are important sources of nutrition and shouldn't be limited).
Experience proves the contrary. Which is why I respect doctors who present and stick by what they find to work in clinical practice ... but not "the other kind."
I was doing great, "coming down" from my nutritional excesses in N'Orleans! Within a very few days I was in ketosis again. THEN a neighbor invited us over for a group dinner and I "sinned" again (why do some people actually take pride in "making" us eat things that are bad for us?). I felt really (physically) horrible for a day or so, but some fasting brought me back to the place I was before, and I am now solidly back in ketosis. J cooked the main course at dinner last night (an Indian dish of cod with a yogurt sauce), but "let" me cook the cauliflower, which needed to be used. I made my faux Party Potatoes dish, and it WAS delicious. But he put a huge mound of it on my plate, and I STUPIDLY finished it.
NEWS FLASH: cauliflower and the rest of its tribe are goitrogens. They're goitrogenous raw. They're goitrogenous cooked. They're REALLY goitrogenous fermented. Short version, they're FUCKING GOITROGENS.
I woke up this morning after sleeping the clock around. I was cold. I was dopey. I was suffering from a big hairy nightmarish lack of thyroid function. I ate ONE CUP OF COOKED CAULIFLOWER, and did nothing else that would have lowered it.
So don't listen to gurus who proclaim, SURE you can eat all the leafy green vegetables you want! They're healthy! They're low-carb! They're loaded with vitamins and minerals and antioxidants and all those lovely dietician-approved phytochemicals that everyone wants to sell you in pill form!
In fact, thiol-containing vegetables cause more problems than they could possibly resolve. Not just for people with "thyroid trouble" -- anyone who benefits from a low-histamine or failsafe diet is well advised to stay the hell away from cruciferous vegetables aka brassicas. Especially, don't eat them fermented! I grit my teeth every time broscience recommends home-made sauerkraut or kimchee....
