Why do astronauts eat freeze dried food i space

The astronauts  had to eat dried food because they didn't know when their food was going to spoil or when they would get more. Its like living of a weeks worth of  groceries for a few months. It took the station a long time to send food because of all the light years ( how many years it takes light to go through space) it takes to get to the space ship with hungry astronauts.
