To clarify the conceptual connotation of plant-based diets and to provide theoretical guidance for research and practice related to plant-based diets.
Literature related to plant-based diets were systematically searched in databases including CNKI,Wanfang Data,VIP,CBM,PubMed,EMbase,Web of Science,and Scopus,with the search period ranging from the inception of each database to December 30,2024.Concept analysis of plant-based diets was performed according to the Walker and Avant method.
A total of 48 articles were included.Plant-based diets encompass three defining attributes:primary food sources being plant-based,diverse food choices,and potential restriction or exclusion of animal products.Antecedents include personal factors,social factors,and economic factors;consequences include health benefits,potential health risks,and environmental impacts.
The conceptual attributes of plant-based diets were clarified through concept analysis.Future research should focus on the positive impacts of plant-based diets to enhance public acceptance,and conduct more systematic and in-depth studies on personalized interventions for plant-based diets.
