For years, beans have suffered from an image problem. They've been called "the poor man's meat," joked about for causing gas, and often relegated to the side of the plate. Yet for thousands of years, beans, lentils, chickpeas, and peas—collectively known as pulses—were among the most important foods on Earth. If bread supplied the calories that built cities, beans supplied much of the protein that sustained them. Long before protein powders and high-protein snack bars, civilizations from Rome to India relied on pulses as an everyday source of nourishment. The Roman laborer's bowl of puls—a hearty porridge often enriched with legumes—was far more representative of daily life than the lavish banquets of emperors. Across the Mediterranean, dishes like pasta e fagioli reflected a simple truth: grains and legumes together formed a remarkably nutritious meal. Modern science has largely caught up with what history already knew. Beans are rich in protein, but they're also packed with dietary fiber, resistant starch, folate, magnesium, potassium, and a remarkable collection of plant compounds that support both heart and metabolic health. Their fiber nourishes the trillions of bacteria living in our colon, producing short-chain fatty acids that help maintain the health of the intestinal lining and may reduce inflammation throughout the body. Perhaps most remarkable is that cultures around the world independently discovered the same dietary pattern. Italy has beans and pasta. India has dal with flatbread. Latin America combines beans with rice or corn. The Middle East gave us hummus. These weren't accidents. They were elegant nutritional solutions developed centuries before anyone knew what an amino acid was. Beans also improve the soil they grow in. Through a partnership with nitrogen-fixing bacteria living on their roots, legumes enrich the earth for future crops. Few foods nourish both the people who eat them and the land that produces them. Today, beans are enjoying a well-deserved renaissance. Heritage producers such as Rancho Gordo have reminded us that beans have flavor, texture, and personality. They're no longer just pantry staples—they're ingredients worthy of the center of the plate. In this week's Fork U podcast, we'll explore how one humble family of plants helped build civilizations, why modern nutrition keeps rediscovering their value, and why the "poor man's meat" may actually be one of the richest foods in human history. Sometimes the greatest superfoods aren't new discoveries. Sometimes they've been quietly simmering in the pot all along.

With all the spices we have access to, it is amazing how bland recipes have become. I have many cookbooks, some from great chefs, television personalities, and friends. What I am always surprised by is how bland the food has become. People seem to think a bit of salt, pepper, maybe onions, and garlic provide the spices one needs. Perhaps it is because some associate spice with heat. Mostly because many have never experimented with some of those great warm spices available. A pinch of coriander, some freshly ground cumin, a little cardamom, or a touch of cinnamon can turn an ordinary dish into something remarkable. And the most astonishing part is that these spices financed voyages around the world, built cities, created fortunes, and caused people to kill one another. Without the spice trade, it is safe to say that the United States, as we know it, would be vastly different from what it is now. The money loaned to the United States, when we were a fledgling country, came from the wealthy spice merchants from what was considered one of the great hyperempires of the world, based in Amsterdam. But before we go to the birth of the United States, let me take you to the meatball.
Tea: The Drink That Built an Empire—and Helped Break One China had the tea. Britain had the appetite. John Hancock had a business to protect.
MesoAmerica and Chocolate In our series looking at foods that built civilizations, today we are going to stay in the Americas with chocolate. Chocolate has been used as currency, consumed by kings, incorporated into religious ceremonies, and prescribed as medicine. Today, it is a multibillion-dollar industry that wants you to believe that eating chocolate is an act of preventive cardiology. I mean, why not? They convinced us to give chocolate to people we love, eat it when we are happy, when we are sad, when only the dog understands us. Don’t feed chocolate to your dog. And we have done all this with a bitter seed that most of us would probably spit out if we tasted it straight from the tree.
I’ve been doing a series about foods that built civilizations. In this episode, we are talking about the potato. It is difficult to imagine that thousands of years ago, people constructed large buildings, managed rivers, built monuments, and created art. We have glimpses of these civilizations through stories, archaeology, and the structures they left behind, but much of their history has been lost. Imagine, we don’t even know where Cleopatra or Alexander the Great are buried, yet we know their stories. As European powers conquered Indigenous peoples, their languages, cultures, and oral traditions were suppressed. When a language disappears, so are the stories preserved within it. Our clues come from archaeology when we uncover a monument, a building, or an ancient settlement. In the Andes, the potatoes they cultivated were not the Russets, Yukon Golds, or fingerlings you find in the store today. Different colors, shapes, and textures. Adapted to survive the elevations, temperatures, and growing conditions. Biodiversity protected their food supply against frost, disease, and changing environmental conditions. If one variety failed, another might survive. The ancient wisdom of diversity that Andean farmers developed over thousands of years was lost when the potato eventually reached Ireland.
In our series about foods that built civilization, we talked a lot about grains, from wheat to corn to rice. Today, we are taking you to the ocean, with the civilizations that salmon built. From California to the interior of Alaska, salmon, a staple, allowed people to settle into villages, develop complex social networks, art, and trade routes. Those trade routes are as large as the ones in the Mediterranean. Some tribes built communal homes and developed complex art and language. Some were Seafaring tribes with canoes up to 60 feet long that traveled across oceans. All because there was a fish that would return in large numbers to streams and rivers, reliably, predictably. So predictable, the people could build their lives around salmon runs. So much so that some built a calendar not only with lunar cycles, but also with the return of the salmon. Civilizations have always gathered around food and water. The Mediterranean connected people who grew wheat and olives, giving people time to make wine, mine copper, build ships, trade with their neighbors, and occasionally go to war with them. Asia had rice and grain near the great river systems. The reliable calories from rice and grains allowed villages to become cities and to travel by water to trade. Today we are going to my home, from the Ventura River in California to my home state of Alaska.
