Food systems generated US$6.1 trillion in global economic value in 2019, yet hunger still persists with 735 million people facing it in 2022. At the same time, consumer markets keep expanding with US$10.0 trillion in annual retail food and beverage sales in 2022, while out of home eating reaches US$3.1 trillion in 2023. This post pieces together those big, sometimes conflicting signals across production, trade, nutrition, and waste.
