For all domestic animals, and for all animals kept in laboratory, complete and precise composition of perfect food is figured out (cat food, dog food, cattle, rats, laboratory monkeys and apes) -- which contains precise composition of carbs, fats, proteins, aminoacids, minerals and vitamins. Everything is known. Convenient dry cat/dog food contains exactly that. Animals are healthy on this food.

The composition is also known for human babies. This is manufactured as "baby formula". Everything baby's organism needs to be healthy (and to grow).

How let's take human adults.

Was ever attempt made to create "dry human 'dog-food'"? This sounds stupid, but there are emergency situation in which such food can come very useful.

So my question is, is there anything special in human biology that prevents creation of complete "dry human food" that contains everything our organism needs to be healthy ?

Or it was created but tasted so disgusting that nobody would eat it ?

Or it actually exist somewhere ? Just curious.
