There are issues where someone takes something and adds unhealthy options. There are also services the campus offers to help students eat healthy. Fitness is a pretty clear goal, but many students don't know how to get there. Physical trainers at the Rec can help you maintain goals. There are ways to eat healthy off-campus.
Many places indicate healthier choices on menus.
A lot of it is common sense. Look at what you are adding to meals in addition to how it's prepared by the server. Eating three meals a day is important. The drink you choose may not be as healthy as it looks. For students still unhappy about the eating options on campus there are ways to voice concerns.
