Food and Nutrition Security/Insecurity
The basic pillars of Food and Nutrition Security are the availability, accessibility, acceptability and consumption and biological utilization of food. Food, of adequate quality, should be available in sufficient amounts to 100 percent of the population. For certain groups, however, the condition of food insecurity is determined by the unavailability of adequate food quality. In other populations these foods may be available, but not everyone has access to them due to financial constraints, distribution and others. Besides the availability and accessibility there are cultural, social, educational and biological factors that affect acceptability, consumption and biological utilization of food.
Considering the close relationship of dependency between the links of this nutritional food chain, from the availability, accessibility, acceptability and consumption to the biological utilization of food, it can be concluded that they are all necessary but not sufficient alone to ensure the nutritional adequacy of individuals.
