Food security exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. The four pillars of food security are availability, access, utilization and stability. The nutritional dimension is integral to the concept of food security and to the work of CFS. The reform proposals made in this document are the results of deliberations between the CFS Bureau and an open Contact Group established to advise the Bureau on all aspects of CFS reform.
