In the context of unsustainable food choices and consumption patterns, transition to plant-based diets is considered a pathway to reducing greenhouse gas emissions. The youths, and university students in particular, represent a distinctive demographic group with great potential to follow plant-based diets, but limited knowledge concerning the prevalence and motivations of plantbased diets exists in the Global South. The aim of this study this research was to examine the prevalence of, motivations for and barriers to plant-based diets among Rhodes University students in South Africa. A total of 300 students responded positively to an online questionnaire survey. About 31% of the survey students followed a plant-based diet but this figure dropped to 18% when flexitarians were excluded from the analysis, with more females than males reporting so. The leading motivation for following plant-based diets was animal welfare concerns, followed by environmental sustainability, personal health, influence of family and friends, taste preference, saving money and sensory issues. There was a significant positive association between values relating to the environment -respecting the earth and protecting the environment and following a plant-based diet. Key barriers to plant-based diets reported included perceived high costs and lack of knowledge on plant-based diets. Interventions for promoting plant-based diets should make explicit, links between plant-based diets and the values people consider important and focus on removing constraints to encourage uptake of plant-based diets.
