Comparison of food recommendations varying in sustainability: Impact on dietary intake and motivation to follow recommendations

Food recommendations increasingly focus on sustainability in addition to nutritional value. By providing participants with standard versus sustainable (plant-based) dietary recommendations for 3 weeks, the present research tested the impact of recommendations on dietary compliance. Furthermore, predictors of food intake were tested across food categories. Participants in the sustainable diet condition complied less with recommendations as compared to those in the standard diet condition and were less motivated to continue complying after the intervention. Taste was the main predictor of intake across food categories. Together, this stresses the importance of considering factors stimulating consumers' compliance when formulating food recommendations.
