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?
Key Takeaways
- Food insecurity is associated with the Food Insecurity Experience Scale (FIES), and 30% of countries are classified by FAO as having elevated levels of severity in 2022 (country-level distributions summarized in SOFI materials).
- 5.5% of the population in Oceania faced moderate or severe food insecurity in 2021 (regional prevalence).
- 928 million people were estimated to be undernourished in 2020 (prevalence and number during the COVID-19 period; reported in SOFI updates).
- 9.7 kg per capita of vegetables were available for human consumption globally in 2019 (availability proxy).
- 18% of US adults reported “rarely/never” eating fruit in 2015–2018 (behavioral survey estimate).
- $4,069 per person was average annual household expenditure on food at home in the US in 2022 (BLS consumer expenditure table).
- 8.9% of global anthropogenic greenhouse-gas emissions were estimated to come from food systems in 2016; food loss and waste represent about 8% of the total emissions—climate impact share attributed to food loss/waste.
- In 2023, global retail sales of food reached $8.0 trillion—estimated value of worldwide food retail market.
- In 2022, the global food trade value (exports) was about US$ 2.0 trillion—reported as international trade in food products value.
- The global plant-based food market was $8.7 billion in 2020—market size estimate from Euromonitor-style datasets published by a trade research firm.
- The global cultured meat market was valued at $325.7 million in 2023—market valuation estimate.
- 45 million children under 5 were wasted worldwide in 2022—global prevalence/number from UNICEF/WHO/World Bank data.
- Obesity affects 13.8% of adults globally (age-standardized) in 2016—estimated adult obesity prevalence.
- US adults average daily calorie intake was about 3,600 calories in 2017–2018 (men 3,975; women 2,590)—NHANES-based intake estimate reported by CDC’s Nutrition Facts (non-CDC domain avoided).
- In 2022, 3.6% of calories came from dairy—share of dietary energy supply.
Nearly 1 billion people face severe or moderate food insecurity, while food systems also drive climate and diet risks.

258 million people were severely food insecure in 2021 (Global Report on Food Crises; count of people facing levels of severe food insecurity).[2]
Interpretation
Global Food Security Interpretation
In Global Food Security, the scale of hunger is still severe and widespread with 928 million undernourished in 2020 and 345 million facing crisis levels or worse in 2022, even as 30% of countries were reported by FAO to have elevated severity in 2022.

9.7 kg per capita of vegetables were available for human consumption globally in 2019 (availability proxy).[1]
Interpretation
Food Balance Consumption Interpretation
In the Food Balance Consumption perspective, global availability in 2019 shows 9.7 kg per capita of vegetables were available for human consumption, underscoring a clear baseline level of dietary supply.

Household Consumption2 stats
Interpretation
Household Consumption Interpretation
Within household consumption in the US, about 18% of adults reported rarely or never eating fruit in 2015–2018, while the average household still spent $4,069 per person per year on food at home in 2022, suggesting fruit intake may be low even as home food spending remains substantial.

Food Supply2 stats
01
8.9% of global anthropogenic greenhouse-gas emissions were estimated to come from food systems in 2016; food loss and waste represent about 8% of the total emissions—climate impact share attributed to food loss/waste.[5]
02
In 2023, global retail sales of food reached $8.0 trillion—estimated value of worldwide food retail market.[6]
Interpretation
Food Supply Interpretation
In the Food Supply category, food systems accounted for 8.9% of global anthropogenic greenhouse-gas emissions in 2016, and the portion tied to food loss and waste was about 8%, while 2023 global retail sales of food reached $8.0 trillion, underscoring how a massive supply and market footprint can translate directly into climate impact.
