The college life doesn't lend itself to traditional meal times, proper portions or basically anything that will benefit a healthy eating lifestyle. Classes can be held at breakfast, lunch and dinner times, which means snacking in between is highly probable. So if you can't avoid eating a few snacks before you head off to class, then choose snacks that will actually help fill you up and keep you healthy at the same time.
Instead of snacking on things like cookies or potato chips try replacing them with some baby carrots or non-fat yogurt. Nutrition Specialist, Dr. Melina Jampolis, recommends college students snack on apples, string cheese, peanut butter and jelly sandwiches, or even mini cans of tuna as alternatives to unhealthy choices. The idea isn't to give up having a quick snack option, because that's probably not realistic, but to replace the bad choice with something much better for you [source: Jampolis].
Some people suggest applying the 35/10/35 rule to your snack habits. This means your snack should be comprised of less than 35-percent fat, 10-percent saturated fat and less than 35-percent sugar per 100 calories. You can apply the same rule to picking your classes: An instructor should require reading less than 35-pages of each book assigned, the final should only be about 10-percent of your grade and there should be a 35-point curve added to every exam. But maybe that's just wishful thinking.
