For centuries, humans have included insects in their diets, consuming everything from beetles to caterpillars, locusts, grasshoppers, termites, and dragonflies. This practice, known as entomophagy, likely began when early hunter-gatherers observed animals foraging for protein-rich insects and decided to follow suit. As human societies evolved, bugs became both a staple food and a delicacy. In ancient Greece, cicadas were considered luxury snacks, while Romans found beetle larvae to be particularly tasty.
So, why have we lost our taste for bugs? The answer lies in history. Around 10,000 BC, in the Fertile Crescent—a key region in the Middle East where agriculture was born—our nomadic ancestors began to settle. As they learned to cultivate crops and domesticate animals, their attitudes shifted, and this change spread to Europe and the Western world. With the rise of farming, insects were increasingly seen as pests that threatened crops. As urbanization took hold, the connection to our foraging past weakened, and people gradually forgot their bug-rich history.
Today, for those unaccustomed to entomophagy, insects are often viewed as nuisances that sting, bite, and infest our food. The “ick factor” associated with bugs leads many to feel disgusted at the thought of cooking and eating them. However, nearly 2,000 insect species are consumed worldwide, forming a significant part of the diet for two billion people, particularly in tropical countries where cultural acceptance is higher. In these regions, insects are abundant, diverse, and often found in swarms, making them easy to harvest.
In Cambodia, for instance, large tarantulas are collected, fried, and sold in markets. In southern Africa, the mopane worm is a dietary staple, often simmered in spicy sauce or eaten dried and salted. Meanwhile, in Mexico, jumiles are toasted with garlic, lemon, and salt. Bugs can be consumed whole or processed into flour, powder, or paste to enhance other foods.
Beyond taste, insects offer significant health benefits. Scientists suggest that entomophagy could be a cost-effective solution for food insecurity in developing countries. Insects can contain up to 80% protein, essential for building the body’s tissues, and are rich in energy-providing fats, fiber, and micronutrients like vitamins and minerals. Many edible insects boast higher iron content than beef, addressing the widespread issue of iron deficiency.
Mealworms, for example, are native to America, easy to farm, and packed with vitamins and minerals. They can contain up to 50% protein, nearly matching beef. Cooking them is simple: sauté in butter and salt or roast with chocolate for a crunchy treat. Overcoming the “ick factor” can lead to nutritional and flavorful rewards. Mealworms taste like roasted nuts, locusts resemble shrimp, and crickets have a popcorn-like aroma.
Insect farming is also environmentally friendly, producing fewer greenhouse gases and requiring less space, water, and food compared to traditional livestock farming. Socioeconomically, insect production could benefit developing countries, as insect farms can be small-scale, highly productive, and relatively inexpensive to maintain. Insects can also be transformed into sustainable livestock feed and reared on organic waste, reducing landfill contributions.
Despite these benefits, many still recoil at the thought of eating insects, imagining legs and feelers getting stuck in their teeth. Yet, consider the lobster—a creature with legs and feelers once deemed inferior and repulsive, now a delicacy. Could a similar shift in perception occur for bugs? Perhaps it’s time to give it a try. Pop that insect into your mouth and savor the crunch.
Research and find a recipe that includes insects as an ingredient. Try to recreate the recipe at home with your family or friends. Document the process with photos or a video, and write a short reflection on your experience. Did you enjoy the taste? How did others react?
Form two groups in your class. One group will argue in favor of entomophagy, highlighting its nutritional and environmental benefits. The other group will argue against it, focusing on cultural perceptions and potential drawbacks. Prepare your arguments and hold a structured debate. Reflect on what you learned from the opposing side.
Imagine you are starting a small insect farm. Research the requirements for farming a specific type of edible insect, such as mealworms or crickets. Create a business plan that includes the costs, potential profits, environmental benefits, and marketing strategies. Present your plan to the class.
Research the nutritional content of various edible insects and compare them to traditional protein sources like beef, chicken, and fish. Create a chart or infographic that highlights the protein, fat, vitamin, and mineral content of each. Share your findings with the class and discuss the potential health benefits of incorporating insects into our diets.
Choose a country where entomophagy is common, such as Mexico, Cambodia, or southern Africa. Research the cultural significance of eating insects in that country, including traditional recipes and how insects are harvested and prepared. Create a presentation or poster to share your findings with the class, including images and interesting facts.
