Food is essential for living as air is for breathing.According to the definition of UN's Food and Agriculture Organization (FAO) food security exists "when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life." 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.
