Special Issue Information

Dear Colleagues,

The need for more prudent eating behaviours that support human and planetary health is well documented. In recent years, these two areas of research have converged considerably. Primary food production and food manufacturing account for a major proportion of global emissions, in addition to land and water usage. With the comprehensive review predicted to take place in 2025 predicting that limited progress towards the United Nations Sustainable Development Goals has been achieved, a Special Issue exploring current research in this area is warranted.

We seek high-quality, original articles and reviews that align with this convergence of both human and environmental health challenges. The scope of this Special Issue includes (but is not limited to) the following:

  • Observational or interventional studies evaluating behaviour change towards more environmentally sustainable and prudent dietary habits.
  • Cosumer-centred studies aimed at understanding perceptions and beliefs around diet and human/plantary health.
  • Studies focused on improving food systems or supply chains for human and environmental health.
  • Emerging interventional evidence evaluating the outcomes aligned with human health and sustainability.
  • The development of novel foods or food products targeting the benefits to human health and the reduced environmental impact of production.

Manuscripts that only focus on one aspect are unlikely to fall within the scope of this Special Issue.

Background/Objectives: Health consciousness has emerged as a key driver of healthy food purchase decisions in the post-pandemic era. Despite growing interest in health-oriented products, the psychological mechanisms through which health consciousness influences purchase intentions remain understudied. This research examined how health consciousness impacts healthy food purchase intentions through multiple psychological pathways, integrating the Theory of Planned Behavior with additional constructs. Methods: Data were collected through an online survey of 573 Peruvian consumers. Healthy foods were operationalized based on their nutritional quality, including a high nutrient content, low saturated fats and added sugars levels, and minimal processing. Structural equation modeling was employed to test the hypothesized relationships between health consciousness, attitudes, perceived behavioral control, self-identity, moral norms, and purchase intention. Results: Health consciousness demonstrated significant direct effects on all psychological mediators (attitudes: β = 0.643; perceived behavioral control: β = 0.593; self-identity: β = 0.638; moral norms: β = 0.613) and purchase intention (β = 0.163). However, only perceived behavioral control (β = 0.261) and self-identity (β = 0.107) significantly influenced the purchase intention, while the effects of attitudes and moral norms were non-significant. Conclusions: The findings challenge traditional assumptions about the primacy of attitudes in consumer decision making and highlight the importance of perceived behavioral control and self-identity in translating health consciousness into purchase intentions. Successfully promoting healthy food consumption requires strategies addressing both practical barriers and identity-related aspects of food choice, providing valuable insights for food marketers and public health initiatives.
