Why so many people find eating insects disgusting

Many people around the world continue to find the idea of eating insects deeply unappealing, despite insects being a traditional and nutritious food source in several cultures. Experts say this reaction is largely driven by cultural conditioning rather than taste or safety, with insects often associated with dirt, pests and disease, particularly in Western societies.

Psychologists explain that feelings of disgust and fear of unfamiliar foods play a major role in shaping eating habits. The appearance and texture of insects can trigger instinctive rejection, even when people are aware of their nutritional value. Studies show that repeated exposure and presenting insects in processed or unrecognisable forms can help reduce this aversion.

Supporters of insect-based diets argue that they offer significant environmental and health benefits, including high protein content and a lower ecological footprint compared to traditional livestock. However, overcoming cultural resistance remains a major challenge, as food choices are strongly influenced by tradition, upbringing and social norms.

As global demand for sustainable food sources grows, experts say changing perceptions around insect consumption may be key to addressing future food security challenges.
