CHICAGO - Long known as late-night outposts of roller hot dogs and greasy pizza, convenience stores now also want to sell you healthier food, preferably lots of it.
This shift in the $550 billion industry was on display at the National Association of Convenience Stores trade show in Chicago this month, a massive and labyrinthine convention of grab-and-go commerce. What began as a few bananas by the cash register is now a full-blown movement aimed at selling healthier fare to consumers - and millennials in particular.
There are practical reasons for this change: Sales of soda, cigarettes, and fuel - longtime pillars of the convenience store business - are in decline. And the rise of e-commerce threatens all brick-and-mortar retail.
"It is a constant evolution. If you think today's model is going to work, you're done," said Jeff Lenard, vice president of strategic industry initiatives for the National Association of Convenience Stores.
The addition of healthier offerings means more choices for consumers. The salad custom-made by a robot - yes, that's a thing that exists - won't replace the roller dogs but might serve as an alternative. More high-protein packaged products like upscale jerky and plant-based protein bars might also be accompanied with more made-to-order food that's marketed as fresh.
The industry shift also means big opportunities for relatively small companies like New York-based Terrafina, which produces nuts, dried fruit, and trail mixes. Just last year, the 12-year-old company began selling its products to convenience stores in small plastic tubs that fit into cup holders and discovered a relative gold mine.
"C-stores are looking for alternatives to tobacco and soda and gas," said Paul Miller, Terrafina's vice president of sales.
"And even alternatives to your regular peanuts," interjected James Locke, CEO of the company.
"And even your processed food products from the 1990s," Miller said. "C-stores are definitely more of a growth opportunity than grocery stores."
At the trade show, protein seemed to be everywhere, marketed in all forms possible. Samples of Soylent, Silicon Valley's darling meal-replacement drink, were doled out just a few booths down from Powerful Yogurt's protein drinks.
"Protein is the new energy," Lenard quipped.
Big Food is getting in the game, too, though. ConAgra Brands - parent company of Slim Jim - recently acquired the maker of Duke's meat snacks and Bigs Seeds. Kraft Heinz has invested in its P3 Portable Protein Packs of meat, cheese, and nuts.
And at the trade show, Hillshire Brands introduced its Small Plates with contents such as apple chardonnay flavored pork and Gouda cheese.
Last year, the convenience store industry saw fuel sales tank 9.2 percent - from $349 billion in 2015 to $316.8 billion in 2016, according to data from the National Association of Convenience Stores. Meanwhile, inside-store sales increased 3.2 percent, from $225.8 billion to $233 billion, with strong growth in healthier food and beverages, according to the trade group.
