What's in a Name? Entomophagy vs. Insectivory
The scientific term for a person who eats insects is an entomophage. The practice of eating insects is known as entomophagy, derived from Greek words meaning "insect" and "to eat". This dietary habit has been part of human culture for thousands of years globally. It's distinct from insectivore, which describes animals primarily or exclusively eating insects. While humans can be entomophagous, few are strictly insectivorous.
The Rich History and Global Presence of Eating Insects
Entomophagy has long been a practical source of nutrition for humans. Archaeological findings indicate ancient ancestors consumed insects. Many cultures, like pre-Hispanic Mesoamericans, heavily featured insects in their diet, a tradition continuing today.
Currently, eating insects is common in tropical areas with abundant insect populations. Notable regions include:
- Africa: Termites and mopane worms are widely consumed.
- Asia: Countries like Thailand and China consume insects such as bamboo worms and crickets.
- Latin America: Mexico has over 450 species on the menu, including grasshoppers (chapulines).
In Western societies, the practice declined due to agricultural shifts and cultural perceptions but is seeing a resurgence due to sustainability concerns.
The Benefits and Challenges of Edible Insects
Nutritional Powerhouses
Insects are a highly nutritious food, offering a healthy alternative to traditional meats. They are typically rich in protein, healthy fats, vitamins, and minerals. Crickets are particularly known for vitamin B12, iron, and fiber content.
Environmental Sustainability
Raising insects is significantly more sustainable than traditional livestock. Benefits include:
- Efficiency: Insects convert feed to protein very efficiently, using less water and land.
- Reduced Emissions: They produce less greenhouse gas than livestock.
- Waste Utilization: Some insects can consume organic waste, aiding in waste management.
Comparison of Insect Protein vs. Conventional Meat
| Feature | Crickets | Beef | Chicken | Fish (Salmon) |
|---|---|---|---|---|
| Protein Content | ~60-70% (dry weight) | ~50% (dry weight) | High (comparable to insects) | High |
| Feed Efficiency (FCR) | Very High (e.g., 1.7 kg feed/kg edible meat) | Very Low (e.g., 10 kg feed/kg edible meat) | Moderate (e.g., 2.5 kg feed/kg edible meat) | High (requires less feed than beef) |
| Water Use | Very Low | Very High | High | Moderate |
| Land Use | Very Low | Very High | Moderate | Low (aquaculture varies) |
| GHG Emissions | Very Low | Very High (large methane producer) | Moderate | Low to Moderate |
| Edible Portion | Up to 80% | ~40% | ~58% | High |
What Kind of Bugs Do Entomophages Eat?
Entomophages consume a wide variety of insects, with preferences varying by culture. Popular choices include:
- Crickets: Often used whole or as flour in various products.
- Grasshoppers and Locusts: Enjoyed fried or seasoned, particularly in Mexico and Asia.
- Mealworms: Known for a nutty flavor.
- Ants: Some types offer a citrusy taste.
- Beetles and Weevil Larvae: Frequently consumed in their larval stage.
- Sago Worms: A delicacy in parts of Southeast Asia.
- Termites: A protein-rich food source in Africa.
Safety Considerations for Eating Insects
While generally safe, there are important safety aspects of eating insects.
Allergies
Individuals with shellfish allergies may experience cross-reactions with insects due to similar proteins. Avoiding insects is recommended for those with this allergy.
Contamination
Insects from the wild risk contamination. Sourcing from reputable commercial farms ensures safety and hygiene.
The Future of the Entomophage
Entomophagy is expected to grow as a food source due to population growth and resource strain. Advancements in insect farming are making insect-based foods more appealing and available. As sustainability becomes more crucial, the term entomophage may become increasingly common, representing an environmentally conscious and nutritious dietary choice. The FAO has highlighted the potential of edible insects for sustainable food systems.
Conclusion
A person who eats bugs is called an entomophage, and the practice is entomophagy. This is a traditional dietary habit for billions globally, driven by cultural history and necessity. Edible insects are gaining recognition as a nutritious and sustainable protein. While allergy and sourcing concerns exist, modern farming improves safety and accessibility. Embracing insects in our diet could contribute to a more sustainable global food system.
