Food Security

The World Food Summit of 1996 defined food security as existing "when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life". Commonly, the concept of food security is defined as including both physical and economic access to food that meets people's dietary needs as well as their food preferences. In many countries, health problems related to dietary excess are an ever increasing threat, In fact, malnutrion and foodborne diarrhoea are become double burden.

Food security is built on three pillars:

• Food availability: sufficient quantities of food available on a consistent basis.

• Food access: having sufficient resources to obtain appropriate foods for a nutritious diet.

• Food use: appropriate use based on knowledge of basic nutrition and care, as well as adequate water and sanitation.
