Wow, very interesting. I am having a similar experience. 2 months ago I had food poisoning from bad apple juice at McDonald's. Well, ever since then every time I eat anything with Red Dye #40 I get extremely nauseas with bad heartburn. Depends on how much I intake, but I had cheesies one night, and I love these things, and 5 hours later I woke up and puked all morning. Then the next week I had licorice and I felt so sick with bad sharp gas pains in my stomach. All food I use to eat beforehand without problems. I can't imagine being in so much discomfort all the time. I've read that in adults food intolerances can be triggered by an illness or gastrointestinal infection, ie Food Poisoning.
