Climate, diet and health are closely connected. The food system is one of the largest contributors to climate change, making it crucial to address dietary choices. This review summarises the current dietary state in Denmark with emphasis on climate and health. Adhering to Danish dietary guidelines or the EAT-Lancet diet not only reduces carbon footprint significantly, but also minimises the burden of disease and pressure on the public health sector. To achieve public health improvements and meet climate targets, it is essential to implement these diet guidelines through comprehensive structural and political measures.
