Navigating the Global Dietary Transition and Its Impact on Planetary and Human Health: The Role of Middle-Income Countries

Abstract This case study examines global dietary transitions and their impact on environmental sustainability, nutritional well-being, and socio-economic inequalities, focusing on middle-income countries (MICs) like China, India, Brazil, Turkey, and Mexico. As economic expansion, urbanization, and cultural shifts drive changes in eating habits, MICs encounter both advantages and disadvantages. The study explores how socio-economic transformation influences dietary preferences, resulting in increased consumption of processed foods and animal-based products, linked to rising non-communicable diseases and environmental impacts such as greenhouse gas emissions and resource depletion. It delves into the influence of cultural heritage and social norms on dietary practices, alongside the impact of Western dietary patterns and media. Additionally, the case study underscores the role of governmental strategies in fostering sustainable and nutritious diets through policies that support local agriculture and public health. It also investigates contributions from the private sector and emphasizes the significance of community-driven and grassroots movements in promoting sustainable dietary habits and reinforcing food security. This study aims to provide insights into the interconnection between dietary transitions, their environmental and nutritional impacts, and the socio-economic drivers and disparities within and across MICs, offering guidance for sustainable development and public health improvement.
