What is the most pratical/feasible method to replace the human digestion apparatus?

+0
−0

Objective: Replace the human digestion apparatus (stomach, guts etc)

From my basic understanding the human body needs food, because it needs ATP (energy unit, some kind of sugar(?)) or you could say high enough (but not too high) blood sugar at most points in time, correct?

Assume you have sufficent technology to rebuild greater parts of the human body (extract organs, rebuild pathways etc), with what would you replace the digestion apparatus?

-> The mouth would be used to talk and breath, nothing more.

What would a theoretical device inject or introduce into the human body?

a Minor idea by me:

Use enriched blood with everything the human body needs. A device enriches the blood by "sci-fi" means and introduces this blood back into the bloodcycle.
Problems:
- The logistics may be a challenge, the device would need a store of vital substances.
- An energy outage would result in quick starvation / brain damage

Would the blood idea be feasible? Do you have a better proposal?

Aspects to ignore:
-> Eating like we do now is obviously the more flexible approach
-> We need to chew etc. to prevent teeth / jaw detoriation.

You have far-future tech to fulfill this objective.

Clarifications:
-The objective is also to make the logistics (for the food recipent) of the whole process as hassle-free as possible. Something like public food pellet dispensers.
- the method of feeding is actually a limitation for the main character to overcome, having undergone this modification "not entirely" voluntary :).
