Food Consumption Statistics

Food Consumption stats bring hunger and climate costs into the same frame, with 30% of countries flagged by FAO as having elevated severity in 2022 and food systems responsible for about 8.9% of anthropogenic greenhouse gas emissions. You can compare what people eat and what it costs, from 54.3% of US calories from ultra processed foods to $4,069 average annual US household spend on food at home.

Food consumption is shaping health and climate in ways that show up fast, even when the datasets change by the year. In 2023, global food retail reached $8.0 trillion, yet hundreds of millions of people still face crisis level or worse hunger. How can spending and supply volumes rise while food security, nutrition quality, and emissions burdens move in such uneven patterns across countries and diets?
