James Hamblin, writing for The Atlantic:
Among people of all ages, she notes, several small studies have now found deterioration in quality of life after the switch. For children especially, imposing a gluten-free diet can be socially isolating. In the journal Pediatrics, kids with celiac disease who attended a week-long gluten-free camp, where every food was gluten free by default, “demonstrated improvement in well-being, self-perception, and emotional outlook”—which seemed to be because the environment “alleviate[d] stress and anxiety around food and social interactions.”
There’s bona fide difference between people who can’t digest gluten and those who adopt the condition to cure unspecified somatic complaints. You can entertain yourself with quackery, but you shouldn’t do that to your kids.
