At the San Juan market in Mexico City, one of the city’s most famous marketplaces, visitors and locals alike stop to study the stalls offering a vivid array of foods. The display includes edible insects, small arthropods, and items like fried aphids, worms, tiny spiders, and chocolate-covered scorpions. There is a growing menu built around native insects and other unusual species, including Madagascar cockroaches. This scene signals a broader conversation about entomophagy and its potential role in future diets.
Globally, about 1,681 invertebrate species are considered suitable for human consumption. Mexico accounts for roughly a third of these. Biologist José Manuel Pino Moreno of the National Autonomous University of Mexico (UNAM), who has researched entomology for more than four decades, notes that his catalog lists as many as 605 edible insect species. His long-standing work highlights how the country sits among the world’s richest regions for edible insects.
For years, the Food and Agriculture Organization of the United Nations (FAO) has recommended insects as a nourishing food source, especially in contexts of hunger and socio-economic stress. The climate crisis intensifies threats to food security worldwide, with droughts and floods disrupting supply chains, particularly in lower-income regions.
In recent research, including a January issue in Science, insect farming is described as a strategy that can ease food-security pressures while supporting developing economies. Europe has moved to regulate edible insects, granting permissions for production and commercialization. In many parts of Asia, Africa, and Latin America, entomophagy remains a traditional practice integrated into local cuisines. In Mexico, the practice is deeply rooted, with insects such as bed bugs, moths, ants, wasps, and termites used in sauces, salts, dressings, and even ice cream, according to Pino Moreno.

Advocates say insects are a plentiful, clean, tasty, safe, and nutritious protein source. They require relatively little space and resources to raise, compared with conventional livestock, and they contribute to a diversified diet when integrated thoughtfully into meals.
An environmental and health-oriented alternative
Keeping intensive agricultural and livestock systems can disturb ecosystems. Breeding insects with high nutritional value, which need minimal land and water, produces fewer greenhouse gases and aligns with traditional eating habits in many regions. In Mexico, for example, grasshoppers, maguey worms, and other insects appear in regional flavors and dishes, and some communities even produce products that showcase these ingredients in sauces, salts, and confections.
Large-scale animal farming demands vast amounts of space, feed, and water. Experts from UNAM argue that ongoing conventional industrial practices carry a substantial environmental footprint. A growing body of research notes the carbon impact associated with meat production, underscoring the need to consider low-cost, sustainable food paths as the global population rises toward 2050. Insects offer a potential supplement to vegetables within a balanced diet, delivering significant protein, fats, vitamins, minerals, and calories. Some comparisons show 100 grams of insects providing notably higher protein levels than certain traditional staples.
Unlike traditional livestock farming, insect farming is characterized by lower greenhouse-gas emissions, reduced space requirements, and lower feed needs. Studies in controlled settings have also highlighted the fatty acids present in several insect species, which can support health when consumed as part of a varied diet. Certain insects boast B vitamins and minerals that differ from other food groups; for example, some varieties provide calcium or phosphorus, while others offer iron and zinc in meaningful amounts. In Mexico, the central and southern regions, including Oaxaca, stand out as traditional hubs for insect collection and year-round sale.
Edible insects and regional culinary traditions
Mexico’s diverse culinary landscape embraces edible insects as part of rural and urban diets. Grasshoppers, maguey worms, chicatana ants, and other insects appear in sauces, salts, and mezcal pairings, and some communities even savor beetle eggs or other insect-based delicacies. This regional richness demonstrates how entomophagy blends nutrition with cultural heritage.
Implications of a growing industry
While the FAO supports insect consumption as part of food strategies, it also stresses strict hygienic controls for production and marketing. Without careful regulation and labeling, consumer safety can be at risk. Experts caution that identifying the source, composition, and handling of edible insects is essential for maintaining trust and safeguarding public health. Contaminants and allergens are possible concerns if standards are not followed throughout the supply chain.
There are practical considerations to manage as production scales. If crops used to feed insects carry pesticides, residues can transfer into insect products. Industry leaders emphasize the need for robust oversight to balance growth with safety and quality. As researchers observe, sustenance from insects should complement, not replace, a well-rounded diet, and it is important to understand each species’ nutritional profile within diverse meals.
In the broader market outlook, some analysts anticipate continued growth in edible-insect commerce, and ongoing innovations in processing and product development are likely to expand consumer options. Careful extraction, handling, and regulation will play a key role in ensuring the sector can contribute responsibly to food security while supporting livelihoods. The topic remains the subject of ongoing, multidisciplinary dialogue that includes nutrition science, environmental policy, and agricultural economics.
