ELI5: Why Gluten-Free diets are so popular now

Is it a fad? Outside of celiac disease, are there any benefits?
gpt
Eating a gluten-free diet is both extremely strict and generally devoid of foods that the average American binge eats. Most of the success of the diet isn't specifically due to the absence of gluten, but due to the dieter's restricted calorie intake and avoidance of nutrient-deficient foods.

Basically, you aren't healthy being gluten free because of the gluten- you're healthy because you stopped eating so much crap.
