This research looks at how changes in China's agriculture and food systems impact food security. The study finds that as more meat is eaten, China relies on imported feed grains like soybeans, which lowers its ability to grow enough food. The connection between these agriculture changes and having enough food is becoming weaker, meaning food security is at risk. To tackle this, China can focus on consuming more grain-efficient poultry and reduce food waste to ensure there's enough food for everyone. These strategies could help other developing countries facing similar challenges with their food systems.
