Millennials have high ethical expectations for the snacks and grab ‘n go foods they eat, according to a new study.

Sixty-four percent of consumers under 35 say there aren’t enough ethically produced snacks available to them, compared to 57 percent of all consumers, according to “Ethics on the Go,” a new study from Chicago-based Culinary Visions Panel’s Mindful Dining Initiative project.

The study also found that 67 percent of millennials say they’d be willing to pay more for ethically produced grab ‘n go foods, compared to 55 percent of all consumers. Three out of four consumers under 35 called ethical efforts made by restaurants “trendy.”

"From sustainable farming to free-range eggs, consumers do not want their dining choices to have unintended negative consequences," says Sharon Olson, executive director of Culinary Visions Panel. "Whether it's rewarding a company's Fair Trade labor practices or their zero-waste policies, we found that millennials are the most serious about ethically-sourced grab-and-go foods.”
