Food and Nutrition Security Theory.

Background: Food and nutrition insecurity continue to affect societies in both developed and developing countries even in years of bounty harvest. This confirms that availability of food does not automatically translate to food and nutrition security (FNS). Even when food is available it may not be accessible to everyone who needs it, and sometimes available and accessible food may not provide all the nutrients required to nourish the body to develop, grow, resist diseases, and meet ordinary physiological demands. Sometimes, food is plenty and accessible but not acceptable or sustainable. All such instances constitute potential food and (especially) nutrition insecurity. Objective: We intend to establish a theoretical framework for investigating food and nutrition security. Method: This is a theoretical paper drawing on previous publications within the scope of food security and nutrition security. Results: The review found that it is imperative to consider carefully the definition of FNS to ensure the two concepts (food security and nutrition security) are adequately and sufficiently addressed in the implementation of food policies and strategies without sacrificing one concept over the other. This balance can be achieved through a thorough needs assessment analysis following the livelihood and the vulnerability approaches to FNS. The analysis should take into account the four conceptual dimensions to FNS to holistically cover every aspect of FNS. Conclusions: The information gathered from the analysis will help prioritize and focus food and nutrition support efforts to the people who really need it, yielding impact measured in public health indicators, education, productivity and the broader national/regional economy.
