Micronutrients Impact

Micronutrient deficiencies can cause several serious health issues. A lack of iron, folate and vitamins B12 and A can lead to anaemia.  Anaemia is a condition in which there is a reduced number of red blood cells or haemoglobin concentration, causing fatigue, weakness, shortage of breath and dizziness.  This can further lead to difficulties in functioning in work, education and community engagement. An estimated 42% of children under 5 years of age and 40% of pregnant women worldwide are anaemic. 

Severe iodine deficiency can lead to brain damage and during pregnancy can cause a number of issues including stillbirth, spontaneous abortion and congenital anomalies. Less severe iodine deficiency may still cause mental impairment that reduces intellectual capacity.  The preferred strategy for the control of iodine deficiency remains universal salt iodization, which requires that all food-grade salt used in household and food processing be fortified with iodine. UNICEF estimates that 66% of households globally have access to iodized salt.

Vitamin A deficiency is the leading cause of preventable blindness in children and increases the risk of disease and death from severe infections such as diarrhoeal disease and measles. Vitamin A deficiency may also occur in women during the last trimester of pregnancy in high-risk areas. Breastfeeding is the best way to protect babies from vitamin A deficiency and, in areas where vitamin A deficiency is a public health problem, vitamin A supplementation is recommended in infants and children 6-59 months of age
