I'll tell you why I care. I'm coming from the perspective of someone that DOES have a rare and strange immune system reaction to a common food. I've seen doctor after doctor for years and no one can tell me what it is. I've tested it over and over and over and my doctors all agree with my assessment. But for some reason, I have to deal with a lot of people that tell me I'm wrong because read something on the internet about it being a fad. Why is everyone so damn certain they have complete knowledge of someone's digestive system and immune system?
