In keeping with many of the other posts in this thread, I draw the line at balut, live bugs, organs, feet, things that stare back and genitalia, though I'd probably try fried/cooked bugs and brains (cooked, please, and not diseased). But as for "normal" foods, there are three that spring to mind that I just can't stomach - the first two are any type, flavor or variety of beer and most red wines. The smell alone from a cabernet or a merlot can make me nauseous at 6 feet. I'm hoping to try port soon to see if the addition of brandy makes any difference. The third? Kraft Macaroni and Cheese. I'm sorry, but that doesn't qualify as cheese, pasta or food. The cheese-food just tastes... weird. And plasticky.
