A new textbook, "Introduction to the U.S. Food System: Public Health, Environment, and Equity" is an anthology of problems faced by the US food system.

The first comprehensive textbook of its kind, Introduction to the U.S. Food System: Public Health, Environment, and Equity, edited by Roni Neff, fills what has long been a conspicuous gap in interdisciplinary academic studies: It integrates the biological, ecological, social, and public health implications of our intricate food system by both informing and challenging the reader to consider how the many components of our food system affect individual and community life. Readers will come away well-equipped to engage in the integrated and interdisciplinary approaches needed to create a sustainable and healthy future.

The textbook quotes writer and environmental activist Wendell Berry to answer why understanding—and consciously participating in—this food network matters: “Eaters … must understand that eating takes place inescapably in the world, that it is inescapably an agricultural act, and how we eat determines, to a considerable extent, how the world is used.”

Comprised of contributions from 106 food system experts including Neff, the 18-chapter, 576-page work was a project of the Johns Hopkins Center for a Livable Future (CLF) at the Johns Hopkins Bloomberg School of Public Health. According to CLF, the textbook exists in response to a growing demand for material at the advanced undergraduate and graduate levels on the multi-layered externalities of the food system.

Chapter One describes the landscape of the American food system: It serves a population of 314 million, selling more than US$1.8 trillion in goods and services each year—including 9 billion livestock. The U.S. food system is responsible for 80 percent of consumptive water use, 52 percent of U.S. land use, 16 percent of energy use, one-fifth of U.S. private sector jobs (about one and a half times that of healthcare), and more than 13 percent of U.S. gross domestic product (GDP). Meanwhile, more than 36 percent of American adults are obese and 15 percent of all Americans are food insecure, according to the textbook.

The text covers issues on public health, ecological impact, implications for communities, equity, and society related to the U.S. food system. Stories and examples of supply, demand, cost, stakeholder interests, history, power, politics and policy, ethics, and culture provide knowledge on transforming policy ideas into legislative realities, chicken farming, food writing, and more.

This textbook is an anthology of problems faced by the U.S. food system. The scope of challenges is presented in an unintimidating manner, for any reader, and in the hope that students will receive much-needed answers in order to advance the U.S. toward a more livable future.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
