Abstract Extensive research has elucidated that dietary factors are pivotal in influencing both human health and the ecological stability of the planet. Suboptimal dietary patterns are implicated in over 10 million annual fatalities attributable to non-communicable diseases. Concurrently, the agricultural sector, a major component of food production, contributes significantly to environmental degradation. This sector is responsible for more than a quarter of global greenhouse gas emissions and utilizes approximately 50% of the planet’s habitable land. Moreover, it accounts for over 70% of global freshwater consumption and is a primary contributor to marine ecosystem disruption through nutrient runoff leading to ocean eutrophication. Despite these critical linkages, current global trends related to dietary practices show little alignment with the improvements needed to achieve the Sustainable Development Goals set for 2030. The existing policy framework and interventions lag considerably in addressing these concerns. Historical and ongoing discussions have repeatedly highlighted these issues, yet the allocation of resources necessary to counteract the pervasive influence of industry-driven marketing promoting less healthful dietary choices remains markedly inadequate. There is an urgent need to intensify dialogues and enhance the conceptual framework regarding the role of diet in sustaining global health and environmental integrity among public health professionals. Such measures are crucial for facilitating a shift towards more sustainable and health-promoting dietary habits globally. The EUPHA Food and Nutrition Section, the Chronic Diseases Section, in collaboration with the World Health Organization (WHO) Regional Office for Europe, aim to propose a joint workshop to share innovative research and activities held in the context of diet and environment. The workshop aims to provide new findings and stimulate the debate about the projections for the future of human and planetary health. Key messages • Human health and environmental preservation require an adaptation of dietary habits globally: are we going in the right direction? • Current evidence suggests that there is an wide area of intervention to improve actual dietary habits, reduce the environmental impact, and improve human health.
