Crawling Towards the Table: Why Humans Aren't Eating More Insects for Protein and Energy

Human dietary preferences have shifted over millennia, and in recent times, the inclusion of insects as a significant food source has been slow to gain traction. This article delves into the reasons behind this reluctance and explores the potential benefits of insect consumption.

Why Isn't Insect Consumption Soaring?

There are several factors that influence human behavior regarding insect consumption.

Eating Habits: Many individuals find insects unappetizing and prefer the cleaner, more palatable taste and texture of aquatic animals. Insects like shrimp and prawn, which are more easily accepted, are still a far cry from terrestrial insects. Physical Appearance: The general aversion to insects may stem from their appearance. Creepy-crawly insects can be off-putting and difficult to swallow, even for those who would not mind the taste. Insect Safety: Some insects, such as those that feed on rotting material, are not considered the safest to consume. The safety and hygiene of insect farming will need to be rigorously addressed to overcome this concern.

Our Inborn Aquatic Instincts

The human species has a long history of consuming aquatic creatures. Our ancestors were adept at hunting and consuming fish, shellfish, and other marine animals, which played a crucial role in survival.

Survival Strategies: Waters served as a refuge and a reliable source of food. Areas rich in aquatic creatures offered a sustainable food source as humans adapted to their aquatic environments. Cultural and Dietary Shifts: The migration of humans from aquatic environments to terrestrial ones coincided with significant cultural and dietary changes. This shift is evident in the global cuisine, with a significant proportion of food sources still being marine-based. Nutritional Benefits: Aquatic creatures are rich in omega-3 fatty acids and other essential nutrients, contributing to a balanced diet.

The Case Against Insects for Protein

While insects can be a valuable source of protein and energy, several factors make their consumption less favorable.

Efficiency: Catching insects can be more labor-intensive than the energy they provide. For example, an anteater can consume up to 30,000 ants in a day, but humans, being much larger and more energy-consuming, would struggle with such high volumes. Hygiene: Insects that feed on decaying matter may not be the cleanest options. Proper sanitary practices and insect farming techniques are needed to ensure that insects are a safe and healthy food source. Energy Cost: Relying solely on insects for protein could be more energy-intensive than traditional land-based animals, especially for large populations.

Conclusion

The reluctance to consume insects for protein and energy is deeply rooted in cultural and biological factors. However, as sustainability becomes a critical concern, the potential of insects as a nutritious and environmentally friendly food source cannot be ignored. Efforts to improve the palatability and safety of insect products may eventually lead to a significant shift in dietary habits.
