Positioning a food as a better4you snack is something brand marketers should consider as data shows that between 1977 and 2006, snacking in the American diet has evolved into a fourth meal, averaging about 580 each day.  Americans like to snack and data suggests workers are heading to vending machines more frequently.  The Institute of Food Technologists say this could be good since more better for you options are now widely available as a growing segment of consumers want healthier options to satiate their appetite during the day.
