The aim of World Food Day, proclaimed in 1979 by the Conference of the FAO of the United Nations, is to heighten public awareness of the world food problem and strengthen solidarity in the struggle against hunger, malnutrition and poverty. The Day marks the date of the founding of the FAO in 1945. In 1980, the General Assembly endorsed observance of the Day in consideration of the fact that “food is a requisite for human survival and well-being and a fundamental human necessity” (resolution 35/70 of 5 December).
