Determinants of willingness to eat insects in the USA and India

One of the major, if not the major impediment to large scale increases of human insect consumption, is the strong rejection of insects as food by most of the world's population. In an effort to understand this aversion, we surveyed online samples of adults living in the USA and India to participate in a study on 'attitudes toward food'. A substantial proportion of both Americans (72%) and Indians (74%) were at least willing to consider eating some form of insect food. Men were more willing to try eating insects than were women, especially in the USA. Disgust seems to be the most common reaction of both groups at the prospect of eating insects. The most common perceived benefits of eating insects were related to nutrition and environmental sustainability, and the most common risks related to risk of disease and illness. Both groups find ants the most palatable of a set of seven possible insects, and cockroaches the most unpalatable. In both samples, participants were most amenable to eating low levels of insect flour in a favourite food, and most averse to consuming whole insects. The best predictors of insect acceptance were disgust at the thought of eating insects, beliefs about the benefits of eating insects, sensation seeking, and the enjoyment of telling others about consumption of unusual foods.
