For the better part of our time here on earth, ice cream did not exist. Neither did sodas, iced tea or even, beer. Enter the refrigerator, and our relationship with food changed dramatically—from being able to store food longer without spoilage to developing an unnatural taste for chilled foods (behold the Jell-o mold!). These foods that now define our culture, like soda, beer and ice cream, simply aren’t the same product without refrigeration. Imagining warm beer, flat soda and runny Ben & Jerry’s makes the absurdity of the situation even more obvious. Refrigeration is certainly a helpful tool in our evolution, but it has led the way to what some experts suggest is actually an unhealthy addiction to cold foods, which also has negative consequences for our health.
