As a graduate of New York’s French Culinary Institute and former chef, I’m obsessed with great food. I can remember the first time I tasted chocolate mousse, pine nuts, and avocados. Years, even decades later, I can recall the succulence of fresh prawns on the Pacific coast of Guatemala, and the fiery savoriness of street food in India. All these moments were shared with family or friends, which made them especially memorable. Breaking bread with others is part of what it means to be human, and the act is wrapped up in emotional well-being, especially love.

Some of my most cherished moments include my mom greeting me on Christmas morning with oven-warm chocolate-chip cookies, or learning at her elbow how to make a proper chicken curry, or watching contentment spread across my partner Michelle Fawcett’s face when I whip up her nostalgia food in the form of salmon teriyaki and rice.

But it’s increasingly uncommon for Americans to eat meals home-cooked from scratch. Instead, 19 percent of us eat fast food several times a week and fully 80 percent eat it once a month or more. The food we eat at home is mostly a matter of heating up food from a factory.

And that’s true even though 76 percent of us say that fast food is unhealthy-testimony to the effect of writers like Michael Pollan, Marion Nestle, Eric Schlosser, and Frances Moore Lappé, who have shown how industrial food is laced with toxins, designed to be as addictive as crack, and chock-full of worker exploitation, animal cruelty, and climate change.

So why do we keep eating junk? The conventional wisdom is that we’re all pressed for time and money, and industrial food is quick and cheap. At least when it comes to cost, that’s not necessarily true. Feeding a family of four at McDonald’s can set you back $25. If you went shopping and cooked at home you could feed four people a hearty, healthy meal at half the price.

And time is not really a problem. Americans on average watch television five hours a day, plus surf the web, play with smart phones, and update Facebook. And if you eat out, not only is it much more expensive than cooking at home, it’s just as time-consuming.
