Nowadays, the dietary behaviour of consumers is an economic and societal concern. Affecting this behaviour remains consequently a challenge for the groups of influences. In this article, we focus on the influence that lobbies and NGOs can exert on the dietary behaviour of consumers. We provide a comprehensive overview and we link the theoretical and empirical economic literature to the influence strategies of these two actors. To be specific, three strategies are exposed and examined: information campaigns, labels and also the dissemination of misinformation. We conclude with a discussion on the consequences and the limits of those influence strategies on certain food sectors (meat, milk and sweet products).
