Abstract
Iron deficiency is the most prevalent nutritional disorder worldwide, especially in developing countries. It occurs when iron absorption cannot compensate iron requirements and losses. Requirements are especially high in pregnant women, infants, young children and adolescents who run a higher risk of being iron-deficient. In developing countries, the main cause of iron deficiency is the low iron bioavailability of the diet. The consequences of iron deficiency are many and serious, affecting not only individuals’ health but also the development of societies and countries. The prevention and the control of iron deficiency anemia in all groups of a population with different iron requirements imply to coordinate different interventions. Anemia, according to the World Health Organization is a condition in which the number of red blood cells or their oxygen-carrying capacity is insufficient. It is mainly caused by iron deficiency and is associated with fatigue, weakness, dizziness and drowsiness. More than 1.6 billion people, almost a quarter of the world’s population, are anemic. Despite considerable economic and scientific advancement during recent decades, there has been, at best, only marginal reduction in the global prevalence of anemia The World Health Organization (WHO) estimates that worldwide, 42% of pregnant women, 30% of no pregnant women (aged 15 to 50 years), 47% of preschool children (aged 0 to 5 years), and 12.7% of men older than 15 years are anemic. The mechanism of hemi iron such liver absorption is regulated by body iron.
