I'm deciding whether to migrate this question from Seasoned Advice or just close it as off-topic:
What is responsible for the recent (last 5-10 years) increase in attention to gluten-free foods?
It's not a poorly-written question, and this is probably the closest site for it, but it might not be close enough. I know that you guys are not crazy about nutrition questions - frankly, neither am I - but it is in the site's title and I thought it might be better to ask.
Regardless of the answer, I'd also like people's thoughts on whether or not we should be migrating nutrition questions in general (assuming that they aren't total crap, but don't relate to fitness either). Is the F&N community interested or not really?
