In Class: how do you decide what to eat

I usually base my decision on what to eat by how I am feeling at the time with a sense of always trying to eat as healthy as possible. I like to know where the food comes from, however, this is tough in today's world. Being in college makes  choosing what to eat very difficult because we are limited in what we can choose to eat as a result of only being able to eat Sodexo. My values of trying to be healthy and sustainable inform most of my eating habits. This is a result of my long-term goals of being healthy so I can live a long and functional life.
