The dietary and health impacts of ultra-processed foods can be understood across the nutri-biochemical, food and dietary pattern levels. Each level reveals distinct dimensions and characteristics that can inform our scientific analysis and policy responses accordingly.
The practice by which international actors consider and engage with negotiations that influence the food system — food systems diplomacy — has the potential to reframe the global food governance narrative to balance the health, social, environmental and economic domains of food systems.
Few microbiome-based solutions for agricultural productivity, food processing and human nutrition have been successfully commercialized. A systems-based approach that considers the ecology of microbial communities may help finetune extant tools to increase their reliability while promoting innovation and greater adoption.
In every country, a clear national strategy, goals and metrics are needed to end hunger, improve nutrition, reduce diet-related diseases and create a just, sustainable and equitable food system. We identify six policy domains where real change can be made to deliver this vision in the United States.
The Ukraine–Russia war will impact global food security over months if not years. In the wake of COVID-19 and in the face of increasing climate change, we propose responses to a multi-layered global food crisis that mitigate near-term food security risks, stabilize wheat supplies and transition towards long-term agri-food system resilience.
