Two books trace the social and historical impacts of food

Salt is one of the cheapest, most commonplace items: It sells for less than a loaf of bread, and during winter, we scatter it liberally on roads and sidewalks. However, there was once a time when salt was considered rare and valuable. In Salt, Mark Kurlansky argues that throughout much of human history, salt was a precious commodity—one that significantly shaped civilizations.

In this guide, we’ll present Kurlansky’s history of salt, describing the role it played in nourishing our ancestors, driving innovation, building empires—and even provoking rebellions. You’ll learn why salting food isn’t just about improving its flavor, why salt harvesting causes sinkholes, and how salt played an important role in several independence movements. Throughout this guide, we’ll supplement Kurlansky’s history of salt with relevant concepts in chemistry, food science, and geology. We’ll also update the book’s ideas with recent research on how we harvest and use salt today.

Think back to your US history classes—how much time did you spend studying Native American perspectives? According to some experts, it probably wasn’t much. History professor and activist Roxanne Dunbar-Ortiz fills that knowledge gap with An Indigenous Peoples’ History of the United States. Published in 2014, this book is a retelling of US history that makes two major arguments: First, the US’s global success can be traced directly to its genocide of Native Americans. Second, indigenous resistance holds the key to a more peaceful future.

In this guide, we’ll discuss life in precolonial America and explain what led Europe to colonize the Americas. Then, we’ll explain how patterns of genocide and resistance have played out over the course of US history. Our commentary will provide additional information and alternative ideas about the historical events Dunbar-Ortiz covers. We’ll also explore social issues related to colonization, explain how Native American resistance efforts intersect with other movements, and provide an update on US-indigenous relations in the 21st century.

The Omnivore’s Dilemma by Michael Pollan explores how we answer the question, “What should we eat.” It traces four types of food chains from a food’s origin to the dinner table. He focuses on how food production in the U.S. has evolved from small farms to a mass production system of huge corn and animal farms operated on factory-based principles. This system has produced cheap, tasty but less healthy foods, while making it difficult for us to make better choices by obscuring our food’s origins and ingredients.

We have a viable alternative in true organic food, but to make better choices and influence change we must do the work of educating ourselves and giving up our addiction to convenience and unhealthy foods.

American society is inundated with food. There are thousands of options of what to eat and a myriad of ways to eat it. So why does food need defending? In In Defense of Food, Michael Pollan distinguishes between real food and processed food and how the reliance on the latter leads to a society plagued by Western diseases.

From our reliance on industry and science to dictate what we should and shouldn’t eat to the loss of traditional food cultures, the Western diet has wreaked havoc on Americans and created one of the unhealthiest societies in the world. But we can reverse the damage if we repair our relationship with food and support the health of the food chain.
