For me, it was a fear driven response to anti-science rhetoric. I think anti-vaccine narrative really convinced me the extent to which people act irrationally about personal health. I observed parents self-diagnosing their children with all kinds of made-up conditions solved only by avoiding certain categories of food like GMOs. As someone with immediate family members with autism, people claiming that removing wheat and dairy from their child's diet would "fix" their "autism" was offensive to me. I trust doctors for the most part to be a superior model to the mommy blogger/anti vaccine crusade. GMOs are another example of misinformation and fear mongering trumping science. I have since learned the value of genetic self awareness and how little we understand about health and diet issues, especially chronic ones, and so have reversed my position towards people with food sensitives, made up or otherwise, to empathize with the fact that we probably don't understand a given issue well enough yet to fix all of the eating problems people have and so people can do whatever they want.
