How This Simple Flag Keeps Your Food Fresh Forever — You Won’t Believe the Science In a world filled with advanced food preservation technologies, one of the simplest tools for keeping your meals fresh has flywheeled into the spotlight: the clever food flag. If you’ve ever wondered why refrigerated food stays better longer—beyond just the fridge itself—you’re about to discover the surprising science behind this everyday hero. ### What Exactly Is the Food Flag?
