I used to think of the supermarket as a nutritionally neutral space, where customers could buy everything from carrots to candy and shelf space was allotted according to consumer demand. But it turns out that, at grocery stores, not all foods are equal. A recent study found that, on average, sugary drinks appear in 25 different places and unhealthy foods in 40 different places in stores. Forgot to buy bell peppers? You won’t see them again once you leave the produce section. But if you skip the soda aisle, you‘ll keep running into soda. End-of-aisle shelves, displays, and checkout lanes keep reminding you to put some in your cart.
