“Food and nutrition security exists when all people at all times have physical, social and economic access to food, which is consumed in sufficient quantity and quality to meet their dietary needs and food preferences, and is supported by an environment of adequate sanitation, health services and care, allowing for a healthy and active life.”

‘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.

Food security can be measured by calories to digest out to intake per person per day, available on a household budget.[12][13] In general, the objective of food security indicators and measurements is to capture some or all of the main components of food security in terms of food availability, accessibility, and utilization/adequacy. While availability (production and supply) and utilization/adequacy (nutritional status/anthropometric measurement) are easier to estimate and, therefore, more popular, accessibility (the ability to acquire the sufficient quantity and quality of food) remains largely elusive.[14] The factors influencing household food accessibility are often context-specific.
