I haven't read anything in WH40K, but I looked at this list and it occurred to me I've eaten a lot of similar stuff on camping trips:
Bread
Cheese
freeze-dried buckwheat porridge
corn crackers
self heating tinned soup
canned fish
heat-treated milk
net-wrapped dry sausage
vacuum-packed soya bars
Dehydrated bean cube soup
Bland meat substitute
Reconstituted broth
Tinned Meat
Tea leaves
Pickled Bell Chilli and Peppers
Rehydrated rice
Fish broth and bread
Fish stock gruel with root vegetables and rye bread
Cold protein gruel with reconstituted fruit juice (half pint daily)
Protein gruel or overcooked meat with sloppy soup
Which leaves stuff that I don't think I've eaten before:
Brown gluey meat product (meat extract with other additives?)
(WTF? Sounds like natto, except natto is from soybeans. But it's definitely brown and gluey. And come to think of it, I have eaten the stuff)
Fish and Starch pudding (piquant)
(This actually sounds somewhat like my great aunt Pearl's gefilte fish. If so, it tastes better than it sounds, particularly with horseradish on top.)
Grey Slop twice a day
(more WTF?)
What's listed isn't wonderful food, but it will keep you going in the field for awhile and if you're hungry you'll eat it. Add the proper vitamins and minerals to the mix and you can probably live on it indefinitely. It's not
ideal nutrition, but hey, there's a war on, right?
I was looking for discussion like
1. Advanced killing tech but lousy basic nutrition
All this feeding of chemical laden food can't be good for a human.
All food is chemicals. All cooking is chemistry.
2. Why in the Grim Future is so much of sci-fi food bland?
Less likely to cause tummy upset.
3. For those with prior service in the military, maybe now you can look on your Combat Ration with some relief your not getting Grey Slop
I do wonder, though, if the military still serves Shit on a Shingle, though...
I know from Titanicus that the Orestes PDF storehouses contain something called "Munitorium-issue reprocessed meat product" in sealed cans. Whatever it is it doesn't sound too appetizing.
Sounds rather like our contemporary
"mechanically separated meat" which, yes, is animal in origin but if you know how it's made I'd question if you'd consider it meat. If you've eaten hot dogs you've eaten this stuff, and it's found in various other products as well.
