Why Do We Eat Meat? A Look at Our Evolving Relationship with Food
Do Humans Need Meat to Survive? A Historical Perspective
For thousands of years, meat has been central to human diets, shaping our evolution and cultural practices. From the hunting traditions that emerged around 1.8–2 million years ago to the protein- and fat-rich diets of early humans, meat played a crucial role in survival and social bonding. While recent research revisits the exact role of meat in human evolution, its cultural and nutritional significance across history is undeniable.
Biological and Evolutionary Reasons for Eating Meat
Meat is a powerful source of essential nutrients—think protein, iron, and B-vitamins—that are crucial at every life stage. For many, some of these nutrients are difficult to obtain solely from plant sources. Our digestive systems reflect this omnivorous adaptation, optimized for a diet that includes both plant and animal sources.
Are Humans Built to Eat Meat?
Humans are classified as omnivores, positioned between animals that don’t eat meat like chimpanzees and true carnivores. Carnivores typically have smaller stomachs and shorter intestines, as they consume nutritionally dense foods that require faster digestion. Herbivores, on the other hand, have larger and longer digestive systems to maximize nutrient absorption from fibrous, less nutrient-dense plant material.
This extended digestive time allows them to extract as many nutrients as possible from their food. Humans show a mix of these adaptations, reflecting an evolutionary reliance on both plant and animal foods. Certain features of human anatomy and digestion diverged from other primates, indicating that our bodies adapted to regularly include meat as a substantial part of the diet.
Cultural and Social Aspects of Meat Consumption
Throughout history, meat has represented much more than just food. It can symbolize power, masculinity, and social identity. In various cultures, it has been linked to class distinctions and social status, with its consumption evolving dramatically over time. For instance, in France, meat was once associated with nobility, but today, its consumption patterns reflect broader societal changes. This complexity shows that our relationship with meat is steeped in cultural narratives and shared experiences.
The Science of Craving: Why We Like the Taste of Meat
Our ability to taste starts with our taste buds, located mainly on our tongue, but also on the roof of our mouth and throat. Each taste bud contains up to 100 receptor cells that respond to five basic tastes: sweet, sour, salty, bitter, and umami (savoury). These signals are processed by the brain, combining with sensory inputs like smell and texture to create the full flavour experience.
Our love for meat is driven by the interplay of taste, smell, and cultural influences. The main reason meat tastes so good is the umami flavour, combined with the richness of fat. When these compounds combine, they create a flavour explosion often referred to as a “u-bomb.”
The Maillard Reaction, which occurs during cooking, enhances these flavours, releasing irresistible aromas that trigger cravings. In fact, the grilling of meat releases one of the most intense aromas of all foods when cooked.
As we navigate our food choices, our early experiences and cultural backgrounds continue to shape our preferences, reinforcing our deep-seated desire for meat.
The Rise of Plant-Based and Sustainable Meat Alternatives
As environmental and health awareness grows, many are shifting toward plant-based and flexitarian diets. Plant-based alternatives have surged, appealing to consumers who want to lower their meat intake without sacrificing flavour. Reducing meat intake has substantial environmental benefits—one study indicates that if people in the UK reduced their meat consumption to under 30g per day, it could match the climate impact of removing 8 million cars from the road. Sustainable choices like these also help conserve water, improve air quality, and reduce greenhouse gas emissions.
