Healthier Snacks
Getting people to wait before pushing the button gets them to pick healthier vending options.
To qualify as "healthy," snacks had to meet 5 out of 7 criteria, such as packing fewer than 250 calories, 350 mg of sodium or 10 mg of added sugars per serving, containing no transfats or getting less than 35 percent of their calories from fat. (Some might quibble with that last point.)
