Food security is the primary goal of food policy in the 21st century. This means ensuring that everyone has access to enough safe and nutritious food to meet their dietary needs.

Climate change, population growth, and urbanization are all major challenges to food security in the 21st century. Climate change is making it more difficult to grow food, population growth is increasing the demand for food, and urbanization is leading to a loss of agricultural land.

Sustainable agriculture is a key component of food policy in the 21st century. It aims to reduce the environmental impact of agriculture, increase the productivity of agriculture, and improve the resilience of agriculture to climate change.

The Food Safety Modernization Act (FSMA), the Codex Alimentarius, and the Hazard Analysis and Critical Control Points (HACCP) system are all key food safety regulations in the 21st century. These regulations aim to protect consumers from foodborne illness.

Food policy plays a role in regulating the food industry in order to ensure that food is safe and nutritious, to promote fair competition in the food industry, and to protect consumers from deceptive marketing practices.
