The social dimension of sustainable diets, which addresses the impacts of food value chains on people, animals and communities, is under-represented in the food systems field. We present a definition of the social dimension of sustainable diets, clarify its boundaries and propose corresponding outcomes. Three case studies highlight the connectivity of social outcomes with the health, environment and economic dimensions of sustainable diets. The continued development of social metrics, data and methods and the implementation of integrated solutions co-developed with affected communities are needed to transform systems and structures that perpetuate unjust and inequitable food systems outcomes. The social impacts of food supply chains on people, animals and communities need to be integrated into sustainable dietary transformations. Here the social dimension of sustainable diets is defined and explored through case studies. Solutions are proposed to support just dietary transformations.

Food Compass is a nutrient profiling system used to assess the healthfulness of diverse foods, beverages and meals. Here we present a revised version of Food Compass (Food Compass 2.0) incorporating new data on specific ingredients and the latest diet–health evidence. Food Compass 2.0 has been validated against health outcomes in a population from the United States and demonstrates enhanced ability to characterize foods and beverages based on their healthfulness. Nutrition profiling systems inform nutritional and health policies to prevent disease and promote health. This study presents a revised version of the Food Compass nutrient profiling system that incorporates the latest evidence linking diet and health—and which has been validated against health outcomes in a US population.

Indigenous peoples are frequently denied the right to own, control and use their traditional lands and resources. Using the example of the Burdekin plum, we explore how this undermines resource access and benefit sharing with Indigenous peoples and hinders scientific research in food innovation.

The bioaccumulation of methylmercury in fish and its biomagnification through the food chain is a major public health concern. Differences in fish methylmercury concentration observed between China and the United States highlight the need for a better understanding of region-specific factors that drive its formation and biological uptake.

The framework presented in the Dublin Declaration has generated controversy by advocating for maintaining or increasing livestock numbers. The serious and acute harms associated with global livestock production today bring the goals of the declaration into dispute.

Fish consumption is a major route of human exposure to mercury. Now, an analysis suggests that human activities have an important role in shaping geographic variations in total mercury and methylmercury concentrations in fish. Although managing mercury contamination is a global issue, local policies are important for more effective mercury management.

Food systems drive human and environmental change, reflect diverse cultural and ecological contexts, and, in their diversity, can bolster nutrition and planetary health. Ignoring structural inequities in food system transformations risks offsetting potential gains. We summarize current evidence on the context-dependent implications of EAT–Lancet goals and propose six priority areas to guide equitable food system transformations, targeting food and nutrition security, just sustainability and cultural diversity. Priority areas—namely, diverse and nutritious food access, food industry regulation, climate-resilient food production, localized, small-scale food systems, cultural diversity and social well-being—can be achieved through public, private and civil society action. The EAT–Lancet Commission has offered recommendations to achieve healthy and sustainable diets, but how to operationalize these recommendations for an equitable food system transformation is unclear. This Perspective proposes six areas under food and nutrition security, just sustainability and food cultural diversity to help ensure equity is set as a priority.

Nitrogen (N) management is the key to achieving food security and environmental sustainability. Here we analyse N flows using a localized N management model for wheat, maize and rice in 1,690 Chinese counties, with a breakdown of multiple reactive N (Nr) loss pathways. Results show that the total N input for producing these three staple crops in China was 22.2 Tg N in 2015, of which 7.4 Tg N was harvested as grain N and 4.0 Tg N was Nr losses in the forms of NH3 (47%), NOx (10%), N2O (3%), and leaching and runoff (40%). By assuming a production level equivalent to that of the top 10% of counties with the highest N use efficiency and yields surpassing the regional average, we reveal the possibility of achieving national staple crop production targets while improving net ecosystem economic benefit in 2050 through a 49% reduction (10.4 Tg N) in synthetic N fertilizer inputs and a 52% decrease (2.9 Tg N) in Nr losses. Staple crop production in China involves high levels of synthetic fertilizer use and losses to the environment. Using a localized nitrogen management model for wheat, maize and rice, this study estimates the environmental and economic benefits of improving nitrogen use efficiency at the county level.

Fish consumption is a major route of human exposure to mercury (Hg), yet limited understanding of how anthropogenic activities drive geographic variations in fish Hg worldwide hinders effective Hg pollution management. Here we characterized global geographic variations in total Hg (THg) and methylmercury (MeHg), compared THg and MeHg levels between the United States and China, and used a structural equation model to link the geographic variability of MeHg in fish to human activities. Despite previously reported higher Hg emissions in China, Chinese fish have lower THg and MeHg levels than fish in the United States owing to a lower trophic magnification slope, shortened food chains and shorter fish lifespans. The structural equation model revealed strong impacts of human activities on MeHg levels in fish. In the future, China may face elevated MeHg levels in fish with the ongoing recovery of food web ecology, highlighting the importance of local policies. Mercury exposure from fish consumption poses a risk to human health, and effective mercury management is hampered by uncertainty about how human activities affect mercury levels in fish. This study presents global geographic variations in total mercury and methylmercury levels in fish and quantifies the impact of human activities.
