Putting food and water between space and interplanetary astronauts is a popularly-discussed option.

I think you may have been down-voted on your tone. This is an optimistic, bleeding-edge project. Unless you are an expert, it is more appropriate to ask why something isn't a problem than to prematurely declare it as unsolved or unsolvable.
