Being a food based approach FF has several advantages over other interventions as it does not necessitate a change in dietary patterns of the population, can deliver a significant proportion of the recommended dietary allowances for a number of micronutrients on a continuous basis, and does not call for individual compliance. It could often be dovetailed into the existing food production and distribution system, and therefore, can be sustained over a long period of time. If consumed on a regular and frequent basis, fortified foods will maintain body stores of nutrients more efficiently and more effectively than will intermittent supplements. Fortified foods are also better at lowering the risk of the multiple deficiencies, an important advantage to growing children who need a sustained supply of micronutrients for growth and development, and to women of fertile age who need to enter periods of pregnancy and lactation with adequate nutrient stores. The limitations of FF are also well known: FF alone cannot correct micronutrient deficiencies when large numbers of the targeted population, either because of poverty or locality, have little or no access to the fortified food, when the level of micronutrient deficiency is too severe, or when the concurrent presence of infections increases the metabolic demand for micronutrients. In addition, various safety, technological and cost considerations can also place constraints on FF interventions. Thus proper FF programme planning not only requires assessment of its potential impact on the nutritional status of the population but also of its feasibility in a given context. Further, it needs to be controlled by appropriate legislation.
