According to the United States Agency for International Development (USAID), food security means having, at all times, both physical and economic access to sufficient food to meet dietary needs for a productive and healthy life (2). Put more simply, families are able to afford and obtain enough nutritious food. A family is food secure when its members do not live in hunger or fear of hunger (2).
The World Health Organization (WHO) defines three main aspects of food security.
The first is food availability,having a sufficient supply of food available on a consistent basis (3).
The second aspect of food security is food access, having sufficient resources to obtain appropriate foods for a nutritious diet (3).
The final aspect of food security is known as food utilization, or consuming a nutritious diet. This means that people make appropriate use of food, based on knowledge of basic nutrition and care, and have access to water and sanitation for preparing food and maintaining proper hygiene (3).
