Curiosity about Insect-Based Foods Grows

If you’ve been a bit skeptical about trying insect-based foods, maybe a recent taste test will change your perspective.

Researchers from Beira Interior University in Portugal explored how people react to these foods by examining brain activity and heart rates while participants sampled insect-based products, alongside traditional surveys.

The study involved 38 adults who had never tried such foods before, asking them to taste both an insect protein bar and a regular cereal bar.

The results were shared at the Eating Behavior Research Association’s annual meeting.

“The researchers assumed participants would prefer the cereal bars and be generally unaware of insect-based options,” a news release explained, “but we found that curiosity and openness were more prevalent than expected.”

Interestingly, some participants were informed of the bar’s ingredients, while others were told they were just eating a cereal bar, not realizing it contained insects.

Physiological responses indicated participants became noticeably more alert while trying the insect-based bars. Plus, heart rates increased, suggesting heightened engagement even when they didn’t know what they were eating.

The researchers concluded that most participants actually preferred the insect-based bars to the cereal ones. It seems that, perhaps, curiosity can indeed override our initial discomfort with such foods.

This aligns with previous surveys indicating that many Americans might be more open to insect products than commonly believed. A YouGov survey from 2021 found that 25% of Americans were willing to try insect ingredients, and 18% were open to eating whole insects.

“In the 21st century, we really need to get innovative to ensure people are nourished, and this study hints at our willingness to explore new food options,” said Dr. Andreia CB Ferreira, the study’s lead author.

Ferreira noted that the study’s findings were unexpected, especially given prior literature suggesting that consumers typically reject novel food sources. It highlights the effectiveness of taste tests in introducing alternatives.

The insect-based food market is on the rise, with projections suggesting it could expand from $1.73 billion in 2025 to $13.23 billion by 2034. This growth is spurred by the increasing interest in sustainable food sources and resource efficiency.

Looking ahead to 2025, beetles are expected to make up the largest share of the insect food market, representing about 33%. Other highly regarded options include yellow and brown mealworms, while crickets and grasshoppers are gaining popularity rapidly.

Dr. Ashley Gearhart from the University of Michigan expressed enthusiasm about consumers possibly embracing these nutrient-rich alternatives.

Insects are already becoming mainstream in some foods, like Chirps Chips made from cricket flour, and various brands are offering protein powders and snack bars featuring cricket ingredients. Even some pet food, such as Jiminy’s grain-free dog cookies, includes crickets and larvae.

In some cultures, insects are not uncommon as street food, and their incorporation into American cuisine is slowly expanding.

Ferreira emphasized the importance of promoting insect-based foods as both nutritious and sustainable.

The study indicates that introducing people to unfamiliar foods through sampling can significantly alter their perceptions. Participants initially voiced anxiety and surprise about eating insects, yet many reported positive experiences after tasting them.

However, the researchers cautioned that this was a small-scale study, indicating the need for larger and more diverse research to gain more reliable insights.
