Role of Micronutrients in Diet of Preschooler
There are several nutrients that have a role in maitaining health and preventing disease. Each nutrient has a particular function in the body and some nutrients are needed in larger quantity as compared to others. Individual requirement of each nutrient is related to age, gender, level of physical activity and state of health for e.g., in a preschooler (child between 1-3 years of age), protein requirement does not increase much but there is an increased need for all vitamins, iron, calcium, phosphorus as well as all other minerals (1) because children are active and growing rapidly. Poor nutrition in the first two years can slow a child's physical and mental development for the rest of his/her life. Apart from adequate proteins and energy, children need micronutrients to prevent illness and protect their physical and mental abilities. It has been found that children with isolated vitamin A and iron deficiency have vision difficulty and impaired physical and mental development respectively and these two are the commonest isolated nutrients deficient in both industrialized and resource poor countries.(2) Deficiencies of vitamin D and zinc are also common in young children. Other micronutrient deficiency is seen frequently with Protein energy malnutrition (PEM) or other systemic diseases. Iodine deficiency, selenium deficiency, vitamin C & B deficiency are seen in specific circumstances.(3)

Several trace elements and vitamins have an essential role in key metabolic pathways in the body. Common vitamins required are
Common minerals and trace elements required by the body are

  •   Sodium
  •   Potassium
  •   Chloride
  •   Iron
  •   Zinc
  •   Copper
  •   Selenium
  •   Iodine


Preschoolers and children are highly vulnerable to micronutrient deficiencies as they have low body stores of these nutrients, they may have low intake due to improper feeding practices and increased losses due to intercurrent infections.(3)
