I am wondering, out of pure curiosity, whether with current medical & biological science, (or indeed with accepted probable future developments in those areas), in theory, would it be possible to create an injection of vitamins, minerals, sugars etc so that eating was no longer necessary, and in fact, an average life with average energy usage could be continued?
I am not a biological professional nor academic, so apologies if this is on the wrong Stack Exchange site, however I thought this was closest to the mark. If there is somewhere more appropriate please direct me, and I shall delete the question and post it there.
Also, if no, would there be certain parts that you couldn't replicate in an injection or something of the like?
NB: This doesn't have to be an injection, any simple method of ingesting or attaining everything the body needs. This could be a pill, or anything. I simply used an injection as an example.
Thank-you very much.
Edit: Having found this question, Has there ever been an attempt to create nutritionally tailored food for adult human consumption? I would like clarify. This has given me a lot of information, however, I am looking for any method APART from food. Thanks.
