Survey on food preferences of university students: From tradition to new food customs?

Humankind currently consumes more resources than our planet is able to generate. In our web survey, we investigated insects and earthworms, as a possible future food source. We targeted the survey to university students, as the possible future consumers and trendsetters of new food. A total of 3556 university students (18–29 years old) completed it. The aims of this study were to evaluate participants’ food preferences and their willingness to taste foods containing terrestrial invertebrates. Data were processed using Cronbach’s alfa to assess the reliability of each constructs. The food preferences showed pizza-focaccia and pasta at the highest rankings, followed by fruit and vegetables. Males have a higher preference for any kind of animal protein source. Gender influenced food preference and willingness to eat food with insect or earthworm ingredients. The results indicated that students were prone to consider novel food into the Italian diet and to familiarize with them in the future. Insects/earthworms were more accepted in salty snacks. Highlighting the essential amino-acids daily requirements of a snack with earthworm meal did not improve the willingness to taste it. Information and awareness of future global food demand can play a fundamental role in accepting new food.
