I guess one might say no chicken as per religious requirements. Other than that, not really anything.

Can’t eat lava because it isn’t food.

I don’t like bones and cartilage. Only meat I eat is ground.

Mushrooms are disgusting. Keep that fungus away from my plate.

Beyond that and a few unusual organs/bugs, I’ll eat pretty much anything.

Low sodium diet for my heart - which is shockingly hard to do. In the US at least, it seems like everything has added salt. It’s absurd how much salt is in a can of beans or soup. I do my best to stay away from premade or processed food.

The saddest thing is that I don’t salt my meals when I cook, at least not really. I love to cook but that really hampers the taste in many many things.

Gluten free. It’s not confirmed fully, but I probably have Celiac as one of my parents does and a DNA test said I was a carrier of at least one known mutation. In Japan, there’s not treatment so getting it fully verified would involve adding gluten back to the diet for weeks, being miserable, and getting nothing but higher life insurance premiums. I miss good bread.

I also don’t drink much dairy as it upsets my stomach in large doses. Cheese is mostly fine (at least for ones without a ton of lactose). I pay for, but still sometimes eat, ice cream on occasion.

Other than that, I try to avoid most processed things. Not 100%, but a lot of what I eat is single-ingredient or homemade.

I’m on a all animal products diet for gut and health reasons. I started doing keto for hypertension, once that cleared up I found full carnivore much easier to maintain. The benefits to my health have been pretty amazing. If I cheat, or go off the food plan, I feel it pretty quickly.

If I eat something with sugar now, I can feel my heart rate increase. If I eat some plant products, I can feel my gut bloating.

It does make eating out a little tricky, but most restaurants have a good option on the menu (poached eggs, grilled chicken, etc)

I can’t have too much salt because I have Menieres disease. It’s a degenerative inner ear problem which means too much salt makes me dizzy, more salt makes my inner ear swell, that leads to feeling like there’s something in my ear and vertigo.

I’m one of the “lucky” ones. I can control it with diet (at least so far) but, other people can’t. That means they live in constant fear of a vertigo attack or even what they call “drop attacks” which makes you feel like you’re pinned to the ground. Often there’s no warning before they hit.

40% or more of my daily calorie intake within an hour of waking up in the morning.

i have some kind of dairy intolerance (untested, lactase only partially alleviates symptoms), threw up eggs recently and now want nothing to do with them, think gelatin and honey are just gross, and am too cheap/worried about contamination to buy meat and fish

all of this adds up to me being basically some kind of mostly vegan but i can’t take ethical credit for it lol

As a lactose intolerant person, I’d have to say it isn’t too hard.

Good quality butter, cheese and yogurt are still in the menu. For me at least, anything were the lactose is broken down sufficiently.

I have no strict lines I draw, but generally I lean towards eating low amounts of beef and cold cuts, for both climate and health reasons.

My philosophy is broadly one of harm reduction, where I don’t necessarily cut anything fully out, but try to choose options that are better for my health and the environment when possible. This basically translates to leaning towards high-protein legume based alternatives as staples - the lunch I eat most frequently is falafel in pita with a variety of vegetables, sauces and hummus: all vegan and pretty respectable with regards to protein - and choosing chicken when I eat meat over other types of meat.

Vegan. Almost four years now and it’s the best thing I ever did for myself.

I’m veggie because it’s so much healthier, cheaper and kind to animals. It’s not hard to stick to, and I’ve no regrets

I have celiac - so no gluten for me. Animal products don’t make me feel great, so I mostly don’t eat those. Sometimes soy is bothersome, so if I can, I avoid that too.
