Abstract The improvement of the global food system requires a thorough understanding of how specific measures may contribute to the system’s transformation. Here we apply a global food and land system modelling framework to quantify the impact of 23 food system measures on 15 outcome indicators related to public health, the environment, social inclusion and the economy, up to 2050. While all individual measures come with trade-offs, their combination can reduce trade-offs and enhance co-benefits.

Transformation to healthier and more sustainable diets in China can generate measurable benefits for nutrition, the environment and food affordability. Integrating multidimensional sustainability goals into China’s dietary guidelines can help to align food policy with long-term societal and environmental improvements.

Abstract The transition to more sustainable diets is critical to achieve the Sustainable Development Goals and meet the Paris Agreement commitments. In China, this transition is particularly urgent due to the double burden of malnutrition and environmental degradation. In this study, we explored the potential of alternative diets in China to enhance public health, ensure food affordability and reduce adverse environmental impacts.
