I wonder if it would be possible for e.g. asteroid material to work as an indirect source of nutrition? I.e. carry a specialized yeast on board that can "eat" the asteroid, and, sort of like sourdough, use the yeast's excess growth as food for humans... Sounds nasty now that I say it out loud haha.

Starmite!

Asteroids which enter a planet's atmosphere will probably yield even better food, because they will be a little meteor.

My 3 year old used to think the dinosaurs are gone because a meat eater killed them all.

The Dodo bird could probably be considered a dinosaur, not entirely wrong...

Earlier quoted context omitted.

Isn’t there a requirement for lots of fibre in the diet as well as vitamins, protein, carbohydrates and fats. As well as the psychological effect of eating good food and not mush.

If I'm in a fragile metal bubble in the deep black vastness of space, the texture of my nutrisludge will be the least existential of my worries.

If Rimworld (the game) is to be believed, people that eat too much nutrisludge will eventually snap and eat the people around them.

Soluble fiber is broken down partially in the gut by bacteria/fermentation. Lots remains. Insoluble fiber passes through mostly unchanged. You see where this is going. You need only minimal new inputs and the rest can be recycled.

To extend D Rumsfeld

there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don't know we don't know.

And now things that we know and wish that we didn’t (ie spaceship recycling)

We're the scary aliens other ETI's make sci-fi horror movies about.
