Brocolli is low on carbs, but tough on the thyroid (as well as cabbage and califlower) - SOOOO if you have any thyroid issues, you might want to avoid it.
Low-carb diets can sometimes be tough on the thyroid too, which is where the carb load comes in.
Easiest way to check is to take your temperature a couple of times a day, and average it out and compare it to normal. If you come out kinda cold, brocolli may not be for you.
I understand that eating all three cooked is preferable (thyroidwise) to raw.
