Many vendors have found that revenue is unaffected by implementing healthy vending: and some vendors have even experienced an increase in sales when they increased healthier options. The transition will go more smoothly with nutrition education, taste tests, promotions, and changes to pricing. More and more people are interested in healthier snacks. According to a 2010 study by the Snack Food Association, about 74% of consumers are trying to eat healthier, with about 65% eating specific foods to lose weight. Sales of healthier snacks are outpacing traditional snack foods by 4 to 1 and contribute to increased sales growth and profits for food companies.
