While 13 percent perishes or is discarded before it even reaches supermarkets or restaurants (so-called food loss), consumers, retail and food service businesses leave another 17 percent unused (referred to as food waste). The UN and the FAO have been tracking food loss since 2015 and have found that its levels have not changed much. As of 2022, food waste per capita varied little between high income, upper-middle income and lower-middle income nations. While sufficient data lacked on low income nations overall, country-level data shows that even among this group of nations, food waste amounts varied significantly. Households are the biggest culprits for food waste as they are responsible for around 60 percent of it.
