Eating Promiscuously: Adventures in the Future of Food

Rate this book
The human practice of farming food has failed. There are 7,500 known varieties of domesticated apples; we regularly eat about five. Seventy-five percent of the world’s food derives from five animals and twelve plants. Factory-farmed meat is a major source of greenhouse gas emissions (about 14 percent, larger than transportation) and consumes 75 percent of the water in drought-prone regions such as the West. We are stuck in a rut of limited choices, and the vast majority of what we eat is detrimental to our health and the welfare of the planet. But what if we could eliminate agriculture as we know it? What if we could start over?


James McWilliams’s search for a more expansive palate leads him to those who are actively exploring the fringes of what we can eat, a group of outliers seeking nutrition innovation outside the industrial food system. Here, we meet insect manufacturers, seaweed harvesters, road kill foragers, plant biologists, and oyster farmers who seek to open both our minds and our mouths—and to overturn our most basic assumptions about food, health, and ethics.


Eating Promiscuously generates hope for a more tasteful future—one in which we eat thousands of foods rather than dozens—with a new philosophy that could save both ourselves and our planet.

Very cool ideas about our food system and alternatives of what we're used to, and the impacts of our current system on our health

This book talks about the dangers of eating a non-diverse diet. McWilliams discusses that as a culture the western world eats about 12 grains and 4 meats and doesn't branch out enough into other foods which is harming our health and the environment. He talks about a bunch of different types of diets and mentions that in his other books he kind of got it wrong. While there's a lot of good information and some useful advice in the conclusion, there's no real easy answer and so it left me feeling like I was doing everything wrong and even if I change it won't be enough because the rest of the world needs to change with me.

An interesting set of thoughts, observations and ideas around diet and where the author thinks we might be able turn to rather than our current diet...
The author has written other works that I didn't agree with much... I don't know... seems like an interesting thought experiment but highly impractical on a massive scale.

For those interested in rethinking food systems, this book offers a fun introduction. If you can get through the first chapter, the book touches on a handful of food alternatives that McWilliams envisions can help make the world a more sustainable place or at least challenge our current ways of thinking.

This is a well written and thoughtful book about the way in which we look at food. It provides much to think about but in the end I did find it a bit depressing because such a sweeping change to the way we eat is pretty unrealistic. Overall, though, I liked it.

A real eye opener. It challenges food habits. It challenges to think about the restaurants and grocery stores they frequent and how they could eat a more diverse range of foods. More than what is actually available.
