Slide 15

Global Burden of Micronutrient Deficiencies Iron insufficiency - all ages Chronic undernutrition – all ages Iodine lack – pregnancy Vitamin An inadequacy – youthful kids PEM – youthful kids Folic corrosive insufficiency – all ages 2 billion* 1 billion* 200 million** 200 million* 167 million* Unknown Source WHO

Slide 16

Iron Deficiency Commonest MND Affects survival, wellbeing and profitability Affects ladies in period of fruitfulness Affects pregnancy and infant Affects development and subjective advancement of newborn children and kids Interaction with vitamin C inadequacy
