My little brother loves the idea of eating suckers with crickets inside of them, along with insects inside of candy in general. Anytime we have gone to a place that sold them, he has asked if he can get one. Every time I think about it, I shudder because I am not the biggest fan of seeing bugs, let alone eating them. But then I think about how there are some nutritional benefits to it, which leads me to wonder: are insects beneficial enough for us to actually add them into our diets? Should we try to get more people to eat them?
Cricket powder and other insect-based ingredients are starting to become more popular in Western culture as people look for alternate ways to produce protein without taking up large tracts of land or causing environmental problems. Other sources of protein farming– most significantly cattle ranching– use up a large amount of land, water, and food and produce a high amount of waste, including methane gas. Farming insects such as crickets, mealworms, and beetles utilizes vastly fewer resources to produce the same amount of protein. Bug farming is a quickly growing industry. However, many companies, such as Ynsect in France, have faced huge opposition from a population that generally loves their meat and dairy and is not ready to give it up yet. This article provides interesting insight into the benefits of insect farming and how it has been received poorly by the general public in France.

The most common form of bug ingredient, cricket flour, cringe-worthy as it may sound, has already made it into a variety of products, sold both online and in stores. Insects have even invaded the chip aisle! So what’s with all the bug food? Briefly put, insects can be just as valuable a food source to us as other species, if not more so. Insects make up an enormous proportion of the species on earth, making them a sustainable choice for our lifestyles in the long run. Thus, the future of food may very well look a little different. With insect products playing a larger role in our diets, meat could very well take a backseat. However far off that time may be, it is important to begin shaping the attitudes of people toward that future beginning today. After all, it will not be easy to change the public perception from creepy to tasty.
“University Student Perspectives of Entomophagy: Positive Attitudes Lead to Observability and Education Opportunities” brings up a big question: how can we change the attitudes of people towards entomophagy–that is, the practice of eating insects as a staple of one’s diet? In the study, Matthew Petersen and his colleagues prove that with a bit of further education, we can accomplish this! I believe the authors intended for us to take away from the article that frequent exposure to entomophagy fosters a more accepting and positive attitude toward it. This message is an interesting one because it allows us to connect with other cultures who practice entomophagy in their daily lives.

The researchers tested just how true the theory “college students will eat anything” is. Through a campus survey and a course survey, nearly 100 students were asked to taste two brownies, one with cricket powder flour and one without. Students in a biology course (course level) and campus-wide (campus level) took a survey describing their familiarity with and attitude toward entomophagy and guessed which brownie had the cricket powder. Those who were part of the campus survey also listened to a short presentation about eating insects before tasting the brownies and answering the questions. The course survey participants were presented with the brownies in an Insect Biology class but were not given an overview of entomophagy beforehand.
The results from these two surveys are quite surprising. For the campus survey, 69 people preferred the brownies with cricket flour while 4 people preferred the traditional brownies, whereas 29 people in the course survey preferred the cricket brownies while 19 people preferred the regular brownies. Participants in both surveys were asked to guess which brownie they thought contained crickets. In the course survey, 34 people guessed correctly while in the campus survey, only 18 people guessed correctly. At the end of the survey period, students in both sections were asked how likely they were to eat insect products in the future, and many of them said they were “extremely likely.”
Additionally, students were asked how likely they were to purchase insect products based on taste, environmental concern, and nutritional value (shown as light gray, black, and dark gray in Figure 5, respectively). As the graph reveals, concern regarding the environment was the most influential contributing factor to the likelihood that students would purchase cricket powder and similar products in the future.
So, what does this mean for us? Should we run to the store in search of cricket flour? For those looking for an experimental change in tastes, sure! On the whole, though, the study reveals that, when we are confronted with insect products in our food, we can seldom differentiate them from the product with which we are already familiar. Beyond that, repeated interaction with entomophagy can lead us to a more positive outlook on the practice as a whole. As revealed in the research, students who already had prior experience with ingesting insects were more willing. Further, after learning about the sustainability of the practice, the attitude shift was by and large positive. This message is an interesting one to contrast with the initial reaction we might have had to the practice of entomophagy. Rather than being disgusted or fearful, these researchers found that students were more than receptive to at least trying the brownies, some even going so far as to say they might seek the experience out again. Not to mention, America is not the first country to indulge in insects as a food source. There are cultures and practices all over the world known for eating insects, and in many places it is not only normal, but a valuable source of nutrition.
That being said, no one is forcing you to add crickets to your cookies this holiday season. However, it is interesting to see the changing attitudes surrounding insects as a sustainable food source in the United States. While presumably not any time soon, there could very well come a time when insects serve as a predominant source of protein, becoming valuable to our health in a way we cannot comprehend yet. The best way we can prepare for that future is to start thinking about it now. The sooner we realize that our creepy crawly friends could very well become precious to our health, the sooner we will be ready for a greener future.
So, the next time you see that scary, buggy corner in the candy shop, maybe you will think twice before wrinkling your nose up. Thanks to Petersen and his colleagues, we might be one step closer to a brand new attitude towards bugs.
