"Something wonderful, something hidden. A gift unique to you. Find it." - Emmerson

 

This summer, the Audubon Nature Institute is opening another museum in New Orleans. Its restaurant will offer everything from soup and main courses to desserts. But the foods will contain ingredients U.S. diners would usually complain about finding on their plates: bugs.

We’re talking about grasshoppers, the worm-like larvae of wax moths, ants — even the occasional dragonfly.

Although unusual as food items, bugs do make sense here because this is the Insectarium (in sek TAIR’ ee um). As its unusual name implies, the entire museum will be devoted to the world’s six-legged species.

Want chocolate chip cookies? They’ll come topped with toasted crickets. And yes, they’re the same kind that chirp in yards and parks all summer long. Make no mistake, these bugs are not just there for looks. You’re supposed to eat them, explains Audubon chef Zack Lemann. The crickets, for instance, “taste kind of nutty,” he notes.

The restaurant will be named Bug Appétit. It’s a play on the French phrase — Bon Appétit (BOHN’ ap pay TEET’) — which means “enjoy your meal.”

Lemann and his Audubon team realize that “eewww” or “gross” may be the first reactions many people will have at seeing bugs in food. But the Audubon center hopes its visitors will leave the restaurant with a better understanding that much of the rest of the world is not turned off by bugs. Indeed, bugs are eaten by choice. What’s more, many insects are actually quite nutritious.

Why Not Eat Bugs?

In America and Europe, most people accept crustaceans such as crab, lobster, and shrimp as food items. In fact, diners often view these foods as special, tending to pay far more for them than for chicken, pork and most beef, or serving them on special occasions. Yet crustaceans are “the ocean equivalent of insects,” says David Gracer.

In fact, crustaceans belong to the same part of the animal family tree as insects do.

When people argue that eating grasshoppers or beetle larvae is yucky, Gracer points out that lobsters tend to “eat trash and dead things.” And Insects? Most of them dine at nature’s salad bars. Knowing that, he asks, “Which would you rather eat?”

Gracer’s primary job is teaching writing to college students. However, in his off hours, he holds workshops on edible insects. He also performs cooking demonstrations to introduce Americans to bug-based recipes. He’s even started a company in Providence, R.I., called Sunrise Land Shrimp. It supplies frozen and dried insects to chefs and other individuals.

Besides pointing out that insects are good food, Gracer also argues that insects can be “a better choice” than most meats — at least ecologically.

It takes a lot of natural resources — land, water, feed and energy — to create a pound of beef or chicken. Those resources are not only costly, but can also be damaged or polluted by livestock operations. By contrast, insects can be grown on low-quality plants — even weeds, sometimes — and often using little water.

The environmental resources associated with bringing every pound of insect protein to market, therefore, are far fewer than for an equivalent amount of regular meat.

That’s why Gracer argues that “cows and pigs are the SUVs of the food world. And bugs — they’re the Priuses, maybe even bicycles.”

Good for the Body

The muscle tissue in conventional livestock — such as cattle, hogs, chicken, and fish — is what we think of as meat. It’s made primarily of protein. By eating protein, we give our bodies a nutrient needed to build structural materials, including muscle.

Insects are tiny animals. And studies have shown that their protein typically has higher quantities of minerals and vitamins than occur in many conventional meats that people eat. That finding was a surprise to Sandra G.F. Bukkens, an independent nutrition scientist based in Barcelona, Spain. While she was working in Italy, several years back, she was asked to survey what scientists around the world had published on the nutritional value of bugs.

“I was pleasantly surprised,” she reports. “Insects were far more healthy than I expected.” Gene R. DeFoliart isn’t surprised by Bukkens’ assessment. His research over the years has shown that the protein in insects tends to be at least as nutritious as that in conventional livestock meats. Sometimes, the insect protein is even better, he says. DeFoliart is an entomologist (en toh MOL’ oh jist), a scientist that studies insects. Although now retired, he worked at the University of Wisconsin–Madison for many decades.

His studies have shown that people throughout much of the world eat insects. Many cultures have eaten them for thousands of years. Although many people in wealthy Asian nations, like Japan, will snack on certain bugs, most insect dining takes place in poorer countries. Insects are popular, for instance, throughout India, much of Asia and Africa, and in South America’s rural populations.

In Mexico, however, insect dining remains common among all classes of people. As a result, insects can be purchased from street stalls or at expensive five-star restaurants, says Julieta Ramos-Elorduy of the National Autonomous University in Mexico City. Indeed, she notes, “I served them at my daughter Mariangela’s engagement party.” And from adults to small children, everyone ate her insect-laden foods, Ramos-Elorduy recalls.

Then again, Ramos-Elorduy knows how to make such meals especially tasty. Over the years she has collected recipes, tried them out, and packaged the best in a picture-filled cookbook, Creepy Crawly Cuisine: The Gourmet Guide to Edible Insects.

Most insects are eaten before they become adults, she told Science News for Kids. The reason: “Their nutritional value is greater, because they have not wasted nutrients while forming such things as wings.” In some instances, people eat the eggs of insects. More frequently, people eat the grub or caterpillar stage of butterflies, beetles and moths. Even young bees, ants and wasps may be added to improve the nutritional quality of food. Altogether, she’s found, some 1,700 different species of insects are eaten in Mexico.
