Bugs are a staple in diets in parts of Asia, Africa, and Latin America, and are also consumed in trendy eating spots across the world. The United Nations' Food and Agriculture Organization reports that about 2 billion people globally already eat insects to supplement their diet. Insects are a rich source of protein, vitamins, and minerals, and can be farmed with less environmental impact than livestock. While the idea of eating bugs may be unappealing to some, it is important to note that the FDA has deemed the presence of bugs in certain foods, such as coffee, broccoli, and chocolate, to be safe for consumption. Additionally, bugs may crawl into your body, particularly through your ears, attracted by earwax, but this is rare and an infection is the worst that can happen.

What You'll Learn
Bugs are already in your food
The notion of intentionally eating bugs may make some people squeamish, but it's not a new concept. Entomophagy, or the practice of eating insects, is common in many parts of the world, with 2 billion people worldwide already including insects in their diets. In fact, the United Nations' Food and Agriculture Organization (FAO) has endorsed the idea, highlighting the nutritional and environmental benefits of entomophagy. According to the FAO, insects are a good source of high-quality protein, nutrients, and fatty acids, comparable to meat and fish.
So, how did bugs end up in your food? It's important to understand that farming and food production are not sterile processes. Insects can crawl or fly onto crops in the field or during harvesting and packaging. They can also infest stored food products, especially dried goods like flour, cereal, and grains. Pantry pests, as they are often called, can lay their eggs in these products, and the insects can hatch and multiply, spreading to other stored foods. While measures are taken to control insect contamination, it's challenging to eliminate it completely.
The good news is that consuming small amounts of bugs is generally considered safe. The Food and Drug Administration (FDA) in the United States, for example, sets "action levels" for maximum insect contamination in various food products. These limits ensure that consumers are not at risk of harm from unknowingly ingested bugs. For instance, the FDA allows for up to 50 aphids, thrips, and/or mites per 100 grams of spinach, and 2,500 aphids per 10 grams of hops used in brewing beer. While the idea of eating bugs may seem unusual to some, it's important to recognize that it's already a part of our diets, and with proper regulations in place, it's not something to be too concerned about.

Bugs are nutritious
The idea of eating bugs may sound strange to Westerners, but entomophagy, or the practice of eating insects, is common in many parts of the world. Indeed, around 2 billion people worldwide already include insects in their diets. The United Nations' Food and Agriculture Organization (FAO) has endorsed insects as a nutritious and sustainable food source in its 2013 report, "The Contribution of Insects to Food Security, Livelihoods, and the Environment".
Insects are a rich source of high-quality protein and nutrients comparable to meat and fish. They are particularly important as a food supplement for undernourished children, as they are high in fatty acids similar to fish. Insects are also a good source of fibre and micronutrients, including essential minerals like iron, zinc, calcium, and magnesium. The protein content of edible insects ranges from 35 to 60 percent dry weight (after being processed) or 10 to 25 percent fresh weight, which is often higher than plant-based sources and can even exceed that of meat and eggs. The fat content of insects varies widely, from 10 to 60 percent, and it is mostly healthy, unsaturated fats.
In addition to their nutritional benefits, insects are also a sustainable and environmentally friendly food choice. They can be raised in small spaces and have a lower environmental footprint than livestock farms. For example, crickets can be raised vertically in climate-controlled facilities, allowing for year-round production. Insects also pose a low risk of transmitting zoonotic diseases, such as bird flu and mad cow disease.
While the idea of eating whole bugs may be off-putting to some, using insects as ingredients in familiar dishes is becoming an increasingly popular way to incorporate them into one's diet. Insect-based products such as cricket flour, cricket powder, and even chocolate-covered bugs are becoming more widely available and can be used in baking or as a protein-rich addition to smoothies or porridge. Celebrity chefs like Jose Andres are also helping to normalize insect-based dishes by including them in their menus, such as tacos with chapulines (roasted grasshoppers) or black ant guacamole.

Bugs are safe to eat
Eating insects, or entomophagy, is a common practice with a long history. Insects have been a regular part of the diet for many human cultures, with over 2 billion people worldwide consuming them regularly. They are particularly popular in Asia, Latin America, and Africa, where they are considered a delicacy and are consumed for their taste.
So, are bugs safe to eat? The answer is yes, for the most part. While it is unlikely that any symptoms will occur, people with shellfish allergies should exercise caution when consuming insects due to the potential for cross-reactivity. Several proteins identified in both shellfish and insects can trigger allergic reactions in sensitive individuals, ranging from mild to severe. A serious reaction known as anaphylaxis can be life-threatening and is characterized by symptoms such as trouble breathing, wheezing, feeling faint, throat or facial swelling, clammy skin, and a rapid heartbeat.
When introducing edible insects into your diet, it is important to purchase them from reputable suppliers. The Food and Agriculture Organization of the United Nations (FAO) recommends following basic food safety guidelines, including cleaning, separating, cooking, and chilling. It is always important to wash hands, utensils, and surfaces that come into contact with raw food. Additionally, it is crucial to use different cutting boards for meat, vegetables, and ready-to-eat foods to prevent cross-contamination. Insects should be cooked thoroughly, and leftovers should be refrigerated within one to two hours.
Bugs are not just safe to eat, but they can also be nutritious and environmentally friendly. They are a good source of high-quality protein, nutrients, and fatty acids comparable to meat and fish. Insects are also rich in fiber and micronutrients. Additionally, they have a lower environmental footprint than livestock farms, as they can be raised vertically in climate-controlled facilities.

Bugs are disgusting
Despite the "ick" factor, eating bugs has several benefits. For one, bugs are nutritious. They are a great source of protein, fat, and minerals. Grasshoppers, for instance, are high in protein and fat but low in carbohydrates. They are also among the most antioxidant-rich insects, containing 5 times more antioxidants than fresh orange juice. Other bugs like crickets are also high in protein and low in carbs. The protein content of edible insects ranges from 35 to 60% dry weight or 10 to 25% fresh weight, which is higher than plant protein sources like cereals, soybeans, and lentils, and can sometimes even be greater than meat and eggs. Bugs are also a good source of healthy, unsaturated fats, fiber, and micronutrients.
In addition to their nutritional benefits, bugs are also good for the environment. Insects can be raised in small spaces with minimal work, and they grow and reproduce quickly, providing a regenerating food source. They can be raised in layers in climate-controlled facilities, leaving a smaller environmental footprint than a livestock farm. Consuming insects could help address food access, cost, and environmental issues, and they pose a low risk of transmitting zoonotic diseases.
Despite these benefits, the idea of eating bugs is still met with hesitation and disgust by many people in Western societies. This may be due in part to long-held stigmas and negative perceptions of insects as dirty or unclean. However, as people become more aware of the benefits of entomophagy, the practice of eating bugs may become more common and accepted, even in Western countries.

Bugs are an ethical food source
Bugs are a traditional food source in many parts of the world, with over 1,900 insect species considered edible. They are a staple in diets in parts of Asia, Africa, and Latin America, and are consumed for their taste. For example, mopane caterpillars are considered a delicacy in southern Africa, while weaver ant eggs are a treat in parts of Southeast Asia.
The future of nutrition may very well include bugs, as they are rich in protein, healthy fats, fiber, and micronutrients such as iron, calcium, and B vitamins. According to the Food and Agriculture Organization of the United Nations, some insects contain up to 80% protein, making them a potent source of plant-based protein. Bugs are also a good source of monounsaturated and polyunsaturated fatty acids, and essential amino acids.
The consumption of bugs is also considered more ethical and sustainable than the consumption of conventional meat. The mass rearing of insects can be done with a lower environmental footprint than livestock farming, as they can be raised in layers in climate-controlled facilities, operating year-round. Bugs also pose a low risk of transmitting zoonotic diseases, such as bird flu and mad cow disease.
However, some people may have psychological barriers to consuming bugs, as they are not traditionally consumed in Western societies. There are also concerns about the animal welfare implications of mass insect farming, as insects are capable of feeling pain and distress, and the potential for similar issues of animal cruelty and exploitation as seen in factory farming.
Ultimately, the decision to consume bugs as an ethical food source depends on individual ethical beliefs and values.
