re: Have you ever snuck in an ingredient that someone "didn't eat"?

I have a friend who is legitimately allergic to gluten. He has been for at least the 15 years I have known him. If he eats it he gets a head ache and feels sluggish and generally like shite the rest of the day. I know "gluten free" is a trendy thing right now, but it is a legitimate allergy.

It's better not to risk poisoning someone just to prove that you are more self righteous than they are.
