#1 The first step to fridge love is to appreciate the gift of modern refrigeration. We have the infrastructure and technology to make the healthiest foods possible, and we take this for granted.

#2 Refrigeration is only about 150 years old. Before that, drying, smoking, salting, slathering foods with honey, pickling, and fermenting were the predominant ways to preserve food.

#3 The first icehouses and refrigeration were in desert civilizations, where getting your hands on some chilled wine or a cool breeze on a stifling day was largely reserved for royalty and the wealthiest citizens. By the early 1800s, American businessmen were jumping into the budding natural ice business.

#4 The first fridges were huge, hulking machines that required trained technicians to operate. They contained chemicals known to be poisonous, and tended to spontaneously explode. It would take over one hundred years of experimenting to find the right combination of gas and machinery.
