Yeah, count me in on the same problem with broccoli causing doubled-over, nauseated cramps. I only experience it with broccoli, not with any other food around the world I've ever tasted. It's even happened when it was cooked into something I ate and I didn't recognize it until after the fact.
I know this is a bit of a stale thread, but does anyone have a method/food/medicine for reducing the impact of the reaction when you have eaten broccoli (accidentally)? Some was snuck into my meal last night and I'm looking around for options. Thank you.
