What dietary requirements do you have and why?

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

Can't eat lava because it isn't food.
- you could eat lava once

Mostly vegetarian, but fish once a week and sometimes can't say no to a good steak. Besides that no added sugar or generally no HPF. Favorite sweet is date with strawberry-powder. Well one could consider that processed but shut up 😁

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.
- Have you tried hummus grated carrot and sultana wraps? Winning combo.
  
  I have not, but I generally eat out for lunch and don't do the primary cooking at home, so it might be a while before I get a good chance to try.
  In fact, the thing I cook the most is microwaved oatmeal, which I flavour with banana milkshake whey and some milk. Not a particularly culinarily sophisticated meal, but healthy and in the very least vegetarian.

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.
- Yep it's hard. I cook from scratch and avoid salt... I try to compensate with heavy flavours like curry spices, oregano etc. You get used to it

40% or more of my daily calorie intake within an hour of waking up in the morning.
- Crikey that's a big percentage, must fill you up for the day though. How hard is it?
  
  I don't know any other way to live.

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 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.
- starting to see chickpea, pumpkin seed, etc. "tofu" popping up in stores and am excited for my friends who can't have soy but would still like to have crispy protein cubes
  
  I love the alternative tofus popping up! I'm eating pumfu right now 😄

Vegan. Cause I think its wrong to harm and kill animals just for taste if we have the possibility to eat plant based. Beside that it's cheaper, healthier and a lot better for the environment.
- Vegan as well. Just learned how to make seitan and it feels like straight up magic.
  
  You're saying you're learning... seitanic magic? 😈
  
  Ohh I tried it myself last year for a BBQ, but I didn't managed the seasoning so it tastes very blank. But I think if you let it soak the marinade for few hours it would taste great! Do you have a quick tip for me?
- And there are some amazing subs now! First time I had a beyond burger I had to check it wasn't meat.
  I couldn't stick to vegan, so stayed veggie. I use soy milk and vegan marge but I've really struggled trying to reduce animal products further. Any tips?
  
  Ohh yess the beyond pattys are pretty solid!
  Which "products" give you a hard time? What helped me, was trying a lot of different products. Took me about 1 year to completely ditch every non vegan food. But you have to learn that you don't need to finde THE product which 100% matches the "original" but rather look for products that you like. Try to realign your eating habits rather than translate your old habits. I have learned to love so many new dishes and foods that I never ate before.
  It may sound a bit silly, but when your in the supermarket and want to buy animal products, always think about what your purchase means for the animals. Think about it for 5 seconds and you immediately don't want it anymore.
- What you said, though in my european country it's not necessarily cheaper. In fact, some vegan foods are crazy expensive. As an aside (not food); i used to buy non-leather shoes pretty cheaply. Then marketing worldwide figured out to call them 'vegan shoes' and bam, expensive shoes...
  
  If you're specifically getting specifically "vegan" products like fake meat or the like it can get expensive, but staples like rice and beans are cheap, vegan, and nutritious.

IBS-M here. I'm intolerant to 4 out of the 6 FODMAP groups, alcohol, fatty foods and gluten are also not well tolerated by my gut. It's pretty frustrating, I can't eat most fruit and all alliums. I can't go vegetarian/vegan either, so I have to adapt a lot and eat pretty much the same 4 things cooked differently. I take probiotics daily to mitigate the symptoms, but it definitely takes a toll. The easiest one to deal with is lactose, because of lactase, but the rest is pretty much no go, or I have to endure days of pain and mood problems.

I don't eat sugar. Well, I guess it's almost impossible to avoid all sugar completely but I don't eat sweets, pastries, jam or any kinds of food with high sugar content. I don't add sugar to any food I make and I always go for the product options with no added sugar if available.
Once you wean yourself off sugar it's actually not that hard to stay away from it, it's funny how that works. I have such low sugar tolerance now that eating candy makes me basically feel ill.
- I try and avoid sugar which is hard cos I love it, I'm down to 3 small things of chocolate per week. My tolerance is deffo down, if I eat chocolate that day I can't stomach any more sugar the entire day
- I'm with you on this. I even switched my SNACKING away from sugary anything.

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

vegan
also found out relatively recently (~7 years ago) that i'm mildly allergic to coconut, i thought the itchy mouth after eating it was normal lol
oh, and a wine allergy, it just gives me a headache very soon after drinking any
- sulfates are the usual cause of wine headaches, it may be worth looking into de-sulfated wine if you otherwise enjoy it

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

I don't eat beans, soy, peanuts, and most derivatives of. Without going into details, let's say that my bowels doesn't handle them well.
e.g. soy sauce and oil are OK, but tofu makes my body scream murder.

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'm somewhat sensitive to lactose. I can take small amounts, like, say, a small ice cream bar twice or thrice a week, but past that ... things go very wrong.
Blood products taste fine to me (blood sausage, black pudding, blood "tofu", etc.) but my stomach rebels when it hits.
I won't touch raw flesh: not steak tartare, not raw fish in sushi, nothing. This is just me hating the taste and texture.
Oh, and rum. Love the taste. Does to me what blood does.
- Crikey there's blood tofu? I've never heard of it!
  
  Well it's not really tofu of course. But it's given the name 鸭血豆腐 (duck blood bean curd) or just 血腐 (blood curd) because, well, it looks and has the vague texture of tofu. (Cheaper alternatives are made with pig or cow blood, but the real thing is duck blood.)

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

Currently im doing 6 weeks of keto. I have picked up my training again and also picked up my fight training. So in order to get that fighter body im on a keto diet.
Also gave me a new appreciation of meat and it supports my local Butcher ^^ I find that it also helps alot with my ADHD and focus :D
