Great question! Steel cans help fight food waste a few ways. First, cans keep food at peak freshness for a long period of time, unlike the fruits and vegetables that you buy in the produce section, which wilt and spoil if you don’t eat them quickly (oh, the guilt). Second, many recipes call for can-sized quantities, minimizing leftover food. And third, the can size has built-in portion control, which also minimizes leftover food that will need to be eaten quickly or else goes bad.
