There is one very important thing I need people without major dietary restrictions to understand: the distress caused by allergies, celiac disease, and other food restrictions is largely not about the food.
Do I miss some foods I can't eat anymore without getting sick? Sure, but that's not what really bothers me. What bothers me is being excluded from a huge portion of human social life of which food is a crucial component. What bothers me is the stress and social stigma of trying to figure out what I can safely eat. What bothers me is the amount of extra work and cost that is required of me to identify, obtain, and prepare safe foods. What bothers me is people treating my needs like a nuisance, as though I chose to be like this - as though their brief inconvenience to check an ingredients list is unreasonable, when I deal with this every day of my life forever.
I don't miss the food that much. I miss not having to worry about what I eat. I miss freedom. I miss when trying new foods and new restaurants was fun instead of a minefield. I miss not having to plan my entire life around the need for safe foods.
Food is such a basic human need, and a lot of people don't really need to think about it. When your danger foods can be anywhere and everywhere, suddenly your entire life revolves around avoiding them, and it massively sucks. You get used to it and it's not a big deal most of the time, but then you go to a new restaurant, or your office has a potluck, or you've been invited to a party and suddenly it feels just as miserable and exhausting as it ever has.
