Consumers switching to vegan diets_a systematic review_IAPNM 19th.pdf

The omnivorous diets have several negative impacts on public health, environment sustainability and animal welfare. Switching to more responsible consumption choices such as vegan, vegetarian or plant-based (veg*an) are healthier, sustainable, and ethical dietary alternatives. There is a growing interest in studying veg*anism and veg*an diets. However, veg*anism continues being overlooked in research, especially within the domain of social-psychology and consumer behavior. Consequently, knowledge toward adhering veg*an diets remain very limited. This paper aims to review and synthesis the related literature on how consumers shift to and maintain veg*an diets. A systematic literature review is conducted through the following four phases: search strategy, exclusion criteria, inclusion criteria, and data extraction. Total of 33 papers were reviewed. Results of synthesized studies showed the process of switching to veg*an diets started by awareness, continued by attitude development, fueled by various motivations, and supported by social and physical factors. These factors could be assessed by more representative and larger samples of consumers in the future.
