The World Food Summit in October, 1996 has defined food security as Food security exist 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 lifestyle (Food and Agriculture Organization of the United Nations, 2001, p. 4) and this definition has been kept within the aspects of food security such as the availability of staple foods, stability of suppliers and access for all to the supplies (Food and Agriculture Organization of the United Nations, 2001).
