Young Adults’ Knowledge, Attitudes and Practices towards Sustainable Nutrition: A Qualitative Study

Abstract

A sustainable diet encompasses a range of environmental, economic, and social goals. Rising dietary shifts have intensified environmental and health pressures, making sustainable food practices a global priority. This qualitative study aimed to assess knowledge, attitudes, and practices towards sustainable nutrition among young adults aged 18 to 25 years, identifying them as pivotal stakeholders in shaping sustainable food systems. Participants were recruited through purposive sampling. In this study, 20 in-depth, semi-structured interviews were conducted face-to-face, audio-recorded, transcribed verbatim, and analysed using thematic data analysis. The results revealed a lack of sensitivity and knowledge regarding sustainable diets and practices. However, an interest in learning more about the habits and behaviours contributing to a sustainable diet was evident. The dominant factor guiding participants’ food choices was personal health benefits. The environmental impact of food production and consumption was poorly understood and largely excluded from dietary considerations. The research highlights a clear gap in both the comprehensive understanding and the practical application of sustainable dietary behaviours.
