Changing our eating habits is so fraught because eating is about far more than food.

Ancient humans must have decided, once their bellies were full, that there was more to life than mere survival and staring mortality in the face. They went on to build things in which they could find distraction, comfort, recreation, and meaning. They built cultures in which death became another rite of passage, not the end of everything. They made structures to live in, wrote songs to sing to each other, and added spices to their food, which they cooked in different styles. Humans are supported by a self-created system of meanings, symbols, rituals, and etiquette. Food and eating are part of this.

The act of ingestion is embroidered with so much cultural meaning that, for most people, its roots in spare, brutal survival are entirely hidden. Even for people in extreme poverty, for whom survival is a more immediate concern, the cultural meanings of food remain critical. Wealthy or poor, we eat to celebrate, we eat to mourn, we eat because it’s mealtime, we eat as a way to bond with others, we eat for entertainment and pleasure. It is not a coincidence that the survival function of food is buried beneath all of this—who wants to think about staving off death each time they tuck into a bowl of cereal? Forgetting about death is the entire point of food culture.
