Micronutrient status of Indian population.

Micronutrients play an important role in the proper growth and development of the human body and its deficiency affects the health contributing to low productivity and vicious cycle of malnutrition, underdevelopment as well as poverty. Micronutrient deficiency is a public health problem affecting more than one-fourth of the global population. Several programmes have been launched over the years in India to improve nutrition and health status of the population; however, a large portion of the population is still affected by micronutrient deficiency. Anaemia, the most common form of micronutrient deficiency affects almost 50 to 60 per cent preschool children and women, while vitamin A deficiency and iodine-deficiency disorders (IDD) have improved over the years. This review focuses on the current scenario of micronutrient (anaemia, vitamin A, iodine, vitamin B12, folate, ferritin, zinc, copper and vitamin C) status in the country covering national surveys as well as recent studies carried out.
