Résumé
Consumer demand is constantly evolving, and in recent years plant-based diets are becoming moreappealing to the general public. However, consumers' preferences evolve at different speeds,integrating environmental concerns, health considerations, and ethical issues. It is thereforeimportant to be able to identify and separate trends in demand among the general public. Fromthe data collected through a survey of 1,715 respondents in France, concerning priorities,preferences, and drivers of change in food choice, we performed an in-depth analysis throughmachine learning techniques such as clustering and classification. While 40% of the interviewedreported that their current diet is different from their ideal, and 98% of them wished to reducetheir consumption of animal products, our analysis revealed several salient variables thatcharacterize different classes of individuals. For example, the willingness to change the diet isstronger for the younger population, while the main obstacles against adopting a plant-based dietare food pleasure, health concerns, and to a lesser extent social resistance and animal ethics. Fromthe analysis, it seems that environmental concerns are the main motivation especially for peoplethat reduce their consumption of animal products in a less radical way
