Keep it out of your mind and you can actually come closer to G-d. Although our food has preservatives and worms will not generally get to our food by morning we can think about how G-d takes care of us constantly. Chovot Halevavot was written in Spain about a thousand years ago. This is found all over the place. He created water in many places because we need it less than air.
Food is needed even less than liquid so that requires a lot of preparation.
If you think about these things daily you can come as close to G-d as the Jews who wandered in the wilderness.
