Freshman Patrick Turner's typical weeknight snack consists of multiple doughnuts, Pop Tarts and other sugary confections in the wee hours of the morning.
"I don't pay attention to what I eat at all," he said.
Although some students are aware of the benefits of healthy eating habits, the majority are not concerned with what they eat, said Jenny Favret, a registered dietitian and nutritionist at the Center for Healthy Student Behaviors.
There are more opportunities for social eating in a college environment, and many students eat unhealthy foods because that's what others are eating or they associate it with studying rather than with actual hunger.
She said the wide variety of foods offered in college dining halls, in contrast to a home environment in which parents dictate food choices, can be a problem as well.
A recent UNC study highlighted that a dramatic rise in soft drink consumption can have enormous health detriments.
In September, Barry Popkin, a UNC professor of nutrition, and Samara Joy Nielsen, a nutrition graduate student, conducted a study of beverage consumption that showed a 135 percent increase in soft drink consumption between 1977 and 2001.
The study also suggested that the increased soft drink consumption is a factor in obesity among Americans.
"I was a little surprised that soft drink consumption continued to go up," Popkin said. "This survey shows that students are consuming more soft drinks more often. This leads to increased calorie consumption, which is not healthy."
