Dietary choices, as the types and amounts of foods that individuals consume, are a major determinant of human health and environmental sustainability. From a marketing perspective, it becomes imperative to identify and understand the factors that motivate consumers to adopt a sustainable diet and purchase healthy food. This research is an attempt to contribute to the literature by revealing the major driving forces leading to healthy food consumption and identifying its underlying mechanism. Based on a survey of the diets and lifestyles of 307 Chinese consumers in several cities of the Jiangxi and Guangdong provinces, our empirical results indicate that consumer health consciousness is a major predictor of the intention to purchase healthy products. Such a relationship is explained by the psychological benefits associated with the consumption experience and the perceived naturalness of the product. Moreover, a high perceived nutritional value will enhance the mediation influences of the psychological benefit and the perceived naturalness on purchase intention while a low perceived nutritional value tends to negate such an impact.

In recent years, with the rapid development of live-streaming commerce, the social dynamics and psychological impact of such online activities merit further discussion. In this study, we investigate the sensory experiences of viewers watching live streaming and examine how these online experiences influence consumer well-being. We developed a conceptual model to understand this mechanism based on the relationship between social presence, shopping enjoyment, familiarity, and consumer well-being. The results of 410 samples indicate that (1) social presence in live-streaming commerce has a significant positive effect on consumer well-being; (2) shopping enjoyment plays a mediating role in the process of social presence predicting consumer well-being; and (3) familiarity plays a moderating role in the second half of the indirect effect of social presence on well-being. This study examines the relationship between social presence and consumer well-being in the context of live-streaming marketing, expanding the research scenario of consumer well-being and clarifying the psychological mechanisms and boundary conditions of the effect of social presence on consumers well-being, which has important implications for online interactive marketing enterprises to enhance social presence and promote consumers long-term well-being.
