Food Justice Defined:

Food justice asserts that no one should live without enough food because of economic constraints or social inequalities. Food justice reframes the lack of healthy food sources in poor communities as a human rights issue. Food justice also draws off of historical grassroots movements and organizing traditions such as those developed by the civil rights movement and the environmental justice movement. The food justice movement is a different approach to a community's needs that seeks to truly advance self reliance and social justice by placing communities in leadership of their own solutions and providing them with the tools to address the disparities within our food systems and within society at large.

Two commonly used definitions of food security come from the UN's Food and Agriculture Organization (FAO) and the United States Department of Agriculture (USDA):

• Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. (FAO)
• Food security for a household means access by all members at all times to enough food for an active, healthy life. Food security includes at a minimum (1) the ready availability of nutritionally adequate and safe foods, and (2) an assured ability to acquire acceptable foods in socially acceptable ways (that is, without resorting to emergency food supplies, scavenging, stealing, or other coping strategies). (USDA)[21]
