Whoever talked about freaking breeding people out of the gene pool with diseases like this, I want to subscribe to your newsletter.
I dated a guy whose sister was allergic to poultry. I was unaware you could even be allergic to it; I'd never heard of that before.
Fast forward to a year or so later when she had a kid, and bam. Kid is literally allergic to EVERYTHING. Has Celiacs, peanut allergy, all kinds of ridiculous stuff. They're at least nice about it; they bring their own food to restaurants for her if they know it would be difficult to get food, and just in general make sure she is taken care of so she's not a burden.
When I found out how the BF and his sister were raised, it made a lot more sense. Their parents never made them eat anything they didn't want to; so anything that was actually good for them or things that most old school parents make their kids eat was just totally ignored. And that's how the two of them were raised, and so on and so forth.
With the way new allergies keep cropping up, it's insanity. I cannot remember a single person back in elementary school who was allergic to peanuts in anyway that was life threatening. Now, a pretty decent % of kids are allergic to it. There has to be a correlation between shitty food trends or diet fads and more allergies popping up. Or maybe it's simply as someone else said; now that we have more information and whatnot about these things we can avoid it and people will live longer, passing their shitty genes on.
Anyways, yea it's a real thing but honestly the only people I've seen who need to follow gluten free to the letter are also allergic to a billion other things too. The people that I've seen who just choose to be gluten free I am almost certain are following a fad diet, OR, they simply feel better when not eating it. Whether that's legit science or just a state of mind thing, who knows.
