Adopting insect-based foods as a norm faces the challenge of the “disgust factor,” a study suggests.
Due to their high protein content, insects could be an eco-friendly alternative to cattle farming, which is a significant source of greenhouse gas emissions.
The prospect of using insect farming to tackle issues of obesity and undernutrition is gaining interest, with many in Asia, Africa, and Latin America already consuming insects in their diets.
Western acceptance of this dietary choice may parallel the increased popularity of sushi over time.
“Insect farming, offering rich protein and nutrients, could address the dual challenge of obesity and undernutrition,” mentioned Dr Lauren McGale of Edge Hill University in Lancashire.
“In comparison to traditional livestock, insect proteins like ground crickets or mealworms are not only more affordable and sustainable but also lower in fat.”
Nonetheless, taste and appearance preconceptions hinder widespread acceptance.
The research indicates that insects ground into powder are more palatable for many people.

Dr Maxine Sharps of De Montfort University highlighted the success of fortifying rice with cricket or locust flours in some regions.
However, just 13% of 603 UK participants express willingness to make insects a regular part of their diet.
Close to half of the respondents remained reticent, and 40% were uncertain.
Many anticipate insect-based food to be crunchy (82%), salty (64.6%), and bitter (62.4%), with a mere 24% believing they would enjoy the taste and only 14.1% thinking it would appear appetizing.

An inverse relationship was observed between age and willingness to try insect-based food, with the likelihood to reject such foods increasing by 2% for every year decrease in age.

“Addressing the disgust factor is paramount,” expressed Dr Sharps.
Given the pressures of climate change and global population growth, alternative food sources like insects might become necessary.
The findings of the study are being shared at this week’s European Congress on Obesity (ECO) in Venice.
FAQ Section
Why are insect-based foods considered environmentally friendly?
Insect farming typically requires less space, water, and feed compared to traditional livestock, and produces significantly lower greenhouse gas emissions.
Are insects a good source of nutrients?
Yes, insects are high in protein and can also provide essential vitamins and minerals, making them a potentially valuable part of a healthy diet.
What is preventing insect food from becoming mainstream in Western cultures?
The primary barrier is the ‘disgust factor,’ which is related to preconceived notions about the taste and appearance of insects as food.
Can insects be incorporated into the diet in a more appealing way?
Yes, insects are more palatable to many people when ground into a powder and used in fortified products, such as cricket-flour-infused rice.
Are there any demographic trends in acceptance of insect-based foods?
Younger individuals tend to be more resistant to trying insect-based foods. Acceptance appears to decrease with each decreasing year of age.
Conclusion
Insects offer a sustainable and nutritious alternative to conventional meats, with potential benefits for both health and the environment. Overcoming the cultural aversion to insect consumption, particularly in Western societies, is crucial for this alternative food source to gain traction. As the findings indicate, while there is resistance, acceptance could potentially increase with strategies that reduce the visibility of insects in their whole form. The evolution of dietary habits—motivated by environmental concerns and an expanding global population—may pave the way for insects to become a more common element on menus worldwide.
