Abstract: In the context of polysemic crisis, the question of full cost must be at the heart of food policies. The hidden costs are induced by negative externalities on human health, the environment, and the economy. According to various estimates, the “true” price of food is twice the price paid by consumers. Even partial inclusion of these costs in market prices poses the dual problem of consumer willingness to pay and food insecurity. Therefore, market mechanisms must be complemented by regulatory mechanisms.
