Quick Answer
At least two billion people globally regularly consume insects, a practice known as entomophagy, providing a sustainable and nutritious food source. Insects are rich in protein and are a significant part of diets in Asia, Africa, and Latin America. The UN views entomophagy as vital for future food security due to its efficiency and environmental benefits, requiring less land, water, and feed compared to traditional livestock.

Quick Answer
At least two billion people worldwide regularly consume insects, a practice referred to as entomophagy, providing a sustainable and nutritious food source.
TL;DR
- Globally, over two billion individuals include insects in their diets.
- Insects offer significant protein content, often comparable to conventional meats.
- Their production is highly efficient, demanding less land, water, and feed.
- Entomophagy dates back centuries, particularly in Asia, Africa, and Latin America.
- The UN views insects as vital for ensuring future food security.
Why It Matters
Integrating insects into our diets could revolutionise global food systems, delivering sustainable nutrition for an expanding global population.
A Global Dietary Staple
The notion that over two billion people consistently eat insects isn't merely a point of interest; it reflects a deeply established dietary pattern across much of the world. This habit delivers essential nutrients and forms a key aspect of numerous cultures.
The UN's Food and Agriculture Organisation (FAO) highlights entomophagy as a crucial component of global food security initiatives. Their 2013 report, "Edible Insects: Future Prospects for Food and Feed Security," emphasised the widespread nature and potential advantages of insect consumption.
Where Insects Are Consumed
Entomophagy is prevalent in diverse regions:
- Southeast Asia: Crickets and silkworms are popular street foods.
- Sub-Saharan Africa: Mopane caterpillars support a multi-million-pound industry.
- Latin America: Chapulines (grasshoppers) are a seasoned snack in Mexico.
This broad acceptance demonstrates how the Western aversion to insects is a cultural exception. For many, insects are simply part of their local cuisine.
Tracing Our Ancestral Diet
Eating insects is not a modern innovation; it is a time-honoured practice. Evidence suggests that our early human ancestors were insect eaters long before hunting larger animals became commonplace.
The Historic Significance of Insects
- Reliable food source: Insects provided a consistent supply of fat and protein.
- Lower risk: Gathering insects was far safer than hunting dangerous prey.
- Accessible: All community members, regardless of age, could participate in foraging.

The Agricultural Transition
In some regions, particularly Europe, the advent of organised agriculture reduced insect consumption. As societies began cultivating crops and domesticating livestock, insects largely shifted from being a food source to being considered pests. This change in perception led to the cultural taboo still observed in many Western societies today.
Nutritional Powerhouses
Insects are remarkably efficient and packed with nutrients. This makes them an attractive option for future food supplies.
Protein Equivalent
- Many insects, such as crickets, offer protein levels comparable to beef.
- They also provide essential amino acids, healthy fats, and vital micronutrients like iron and zinc.
A study published in the journal PLoS ONE indicated that yellow mealworms contain similar levels of protein, fat, and minerals to beef or chicken.
Environmental Advantages
Farming insects requires significantly fewer resources than raising traditional livestock.
- Less land: Insect farms operate in compact spaces.
- Less water: Insects need minimal water compared to cattle.
- Less feed: Crickets, for example, require six times less feed than cattle for the equivalent protein output, according to the FAO.
- Reduced emissions: Insect farming generates substantially lower greenhouse gases.
These factors position insects as a highly sustainable protein source.
Practical Applications and Future Trends
The global interest in entomophagy is growing, pushing insects beyond traditional diets.
Innovative Food Products
- Protein bars: Many companies now incorporate cricket flour into energy bars.
- Insect-based flours: Used in baking and cooking to boost nutritional content.
- Whole roasted insects: Available as snacks in adventurous markets.
These products are slowly making their way into mainstream supermarkets, particularly in regions like Europe and North America.
Policy and Research Efforts
Organisations worldwide are investing in insect farming research and development. The European Union, for instance, has approved certain insects for human consumption, paving the way for a new industry. This includes species like the mealworm and the migratory locust.
The challenge now is to overcome cultural biases and encourage broader acceptance. For perspectives on mastering social challenges, see Master Your Social Vocabulary: A 3-Word Micro-Challenge for Natural Sophistication.
Connections to Broader Sustainability Goals
The role of insects in our diet is intrinsically linked to larger environmental and economic discussions.
Circular Economy Potential
Insect farming can contribute to a circular economy. Insects can convert organic waste into high-quality protein for both human consumption and animal feed, reducing food waste and reliance on conventional feed sources. This aligns with principles of What "The Best Way Out Is Always Through" Means (and What People Miss), tackling challenges head-on.
Global Food Security
As the world population approaches 10 billion, finding sustainable protein sources is critical. Insects offer a viable solution, especially for developing regions where food insecurity is a pressing issue. Their ease of farming and high nutritional value make them a powerful tool in combating hunger.
Key Takeaways
- Over two billion people routinely eat insects, a widespread global practice.
- Insects are highly nutritious, providing protein, essential amino acids, and micronutrients.
- Their cultivation is environmentally superior to traditional livestock farming.
- Entomophagy is an ancient dietary habit, particularly prevalent in many non-Western cultures.
- The UN considers insect consumption vital for ensuring future food security and sustainability.
