Iron Deficiency:Iron deficiency is the most widespread form of nutritional deficiency globally. Iron is essential for creating hemoglobin, the molecule in red blood cells responsible for oxygen transport. A lack of iron leads to anemia. This deficiency is most prevalent among young children and women of childbearing age, particularly those who are pregnant. In pregnant women, insufficient iron levels heighten the risk of premature birth and delivering infants with low birth weight. In children, iron deficiency can result in developmental delays, behavioral issues, and increased susceptibility to infections. Treatment involves incorporating iron supplements and iron-rich foods into the diet. Sources of iron include meat, poultry, eggs, vegetables, and cereals, especially those fortified with iron. However, children should only receive iron supplements if advised by a physician.
