Abstract

Plant-based diets have gained attention in recent years due to potential benefits for human health and the environment. One concerning aspect of plant-based eating is the potential link to “diet culture”. The purpose of this study is to explore the theory that consumption of a plant-based diet is associated with diet culture beliefs.

This study involved a national survey of 2750 rural adults and interviews with 28 plant-based adults in Vermont. Survey responses were collected July-November 2023 and focused on dietary motivations and diet culture. Responses were analyzed using chi-square and binary logistic regression models. Qualitative interviews were conducted in July-September 2022 and focused on perceptions of and experiences with plant-based diets. Transcripts were thematically coded and analyzed for diet culture attitudes and behaviors.

Plant-based eaters were more likely to be motivated by health than omnivores. Flexitarians were more likely to be motivated by weight. Semi-vegetarians were more likely to agree with the diet culture statements than omnivores. References to diet culture were evident in 75% (n=21) of the interviews. Processed foods and animal products were described as “unhealthy”, and participants promoted restrictive diets and weight loss.

Compared to omnivores, semi-vegetarians but not strict vegetarians or vegans were more strongly motivated by the desire to restrict “unhealthy” foods. For these individuals, the dietary pattern appears to align with the moralization of foods under the guise of pursuing health or environmental goals. Further research with more diverse samples is needed to confirm and extend these findings.
