How Entomophagy Works

Entomophagy -- the practice of eating insects -- is common outside of Europe and North America. Despite cultural taboos, you've probably eaten insects without knowing it. Check out our HowStuffWorks podcast to learn more about entomophagy.

Topics Discussed

Episode Summary

Executive Summary: The transcript is a stitched promo reel built around a comedic Stuff You Should Know segment on entomophagy, the eating of insects. The hosts discuss its history, global cultural acceptance, FDA “defect” tolerances in foods, nutritional benefits, and safety tips, while multiple iHeart podcast ads interrupt the flow. The insect-eating discussion argues that bugs are common, nutritious, culturally normalized in many places, and often less taboo than Western listeners assume.

Main Topics: Entomophagy as a global practice (Priority: 5/5): The hosts explain that eating insects is common across many regions, especially outside Europe, Canada, and the U.S., and is shaped by local availability and culture. Historical and religious precedent (Priority: 4/5): They reference biblical dietary rules, the Old Testament, and examples from Greece, Rome, Australia, and Mexico to show insect consumption has deep historical roots. Cultural taboo vs. acceptable foods (Priority: 4/5): The discussion contrasts Western disgust with the acceptance of insects and compares them to other arthropods and seafood like lobsters and crabs. FDA food defect standards (Priority: 5/5): The hosts highlight federal allowances for insect fragments, rodent hairs, and other unavoidable contaminants in packaged foods, using the FDA handbook as a gross-out example. Nutritional value of insects (Priority: 5/5): They argue insects can be high in protein, iron, and vitamins, with caterpillars singled out as especially nutrient-dense and comparable to salmon. Safety and survival guidelines (Priority: 3/5): Practical advice is given for collecting edible insects, including avoiding brightly colored species and being cautious about pesticide exposure. Podcast advertisement interludes (Priority: 2/5): The transcript repeatedly cuts away to promos for other iHeart shows, especially Hey Jonas, A Slight Change of Plans, Rebel Spirit, and We the Unhoused.

Key Arguments: Insects are widely eaten around the world because they are abundant, cheap, and nutritious. The practice has historical legitimacy, appearing in biblical, Greek, Roman, Aboriginal, and other traditions. Western disgust is cultural rather than objective; people readily eat other arthropods like lobster and crab. The FDA permits small amounts of insect fragments, rodent hairs, and other contaminants in food because they are unavoidable and not usually harmful. Insects can provide strong nutrition, including protein and iron, with some species rivaling salmon. If collecting insects to eat, consumers should avoid brightly colored species and be mindful of contamination from pesticides.

Data Points: Edible insect species: More than 1,400 - The hosts note there are over 1,400 edible insect species. Edible beetle kinds: Close to 350 - They mention nearly 350 kinds of beetles alone are edible. Cultural groups consuming bugs: About 3,000 ethnic groups - The transcript cites roughly 3,000 ethnic groups around the planet that eat bugs. Cricket nutrition: 121 calories per 100 grams - Nutritional content cited for 100 grams of crickets. Cricket protein: 13 grams per 100 grams - Protein amount in 100 grams of crickets. Cricket iron: 75 milligrams per 100 grams - Iron amount in 100 grams of crickets. Caterpillar protein: 28 grams per 100 grams - Protein content used to illustrate caterpillars as a high-protein insect. FDA broccoli contamination: 60 or more aphids and/or mites per 100 grams - Example of allowable insect presence in frozen broccoli. FDA cinnamon contamination: 400 or more insect fragments per 50 grams - Example of allowable contamination in ground cinnamon. FDA macaroni/noodle contamination: 225 insect fragments and 4.5 rodent hairs per 225 grams - Allowable contamination in macaroni or noodle products. FDA pepper contamination: 1 milligram or more of mammalian excretia per pound - Allowable defect level cited for peppercorns. FDA popcorn contamination: 1 or more rodent excretia pellet per subsample - Allowable defect level cited for popcorn.

Pivotal Quotes: "Eat a bug." — Josh Clark: The hosts jokingly introduce the idea of entomophagy and their personal discomfort with it. "black, green, brown, wolf it down." — Chuck Bryant: A survival rule of thumb for which insects are safer to eat based on coloration. "If day-old chickens had no bones, hair instead of feathers, and were the size of a newborn sparrow, they might taste like tarantulas." — Peter Menzel: Quoted description used to help listeners imagine the taste/texture of tarantulas.

Implications: For listeners, the segment reframes insects as a legitimate food source rather than a novelty, emphasizing nutrition, cultural context, and food-system realities. It also shows how media interruptions shape podcast listening.
