Differences in perspectives on sustainability attributes of dietary protein sources between reduced animal-based dieters and nondieters

This study investigates the perceived sustainability of eight common protein sources among reduced animal-based dieters (RABs) and nondieters (NDs) in Hungary. A cross-sectional online survey (n=541) measured demographic data, food consumption frequency, perceived healthiness, and environmental friendliness. Conjoint analysis assessed the importance of sustainability attributes (nutritional score, ecological score, price, product category). Results showed that RABs underestimated the healthiness of animal-based products, while NDs underestimated their environmental impact. Plant-based foods and nutritional scores positively affected choices for both groups, while all animal-based sources negatively impacted RABs' choices. The study highlights the need for tailored communication strategies to promote sustainable food choices among diverse dietary groups.
