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

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

Global Burden of Iron Deficiency Source WHO

Benefits of Preventing Iron Deficiency Benefits to kids Improved behavioral and intellectual improvement Improved kid survival (where extreme paleness is normal) Benefits to teenagers Improved psychological execution Better iron stores for later pregnancies (females)

Benefits to Pregnant Women and Their Infants Decreased low birth weight and perinatal mortality Decreased maternal mortality and obstetrical inconveniences (where serious weakness is normal) Benefits to all Individuals Improved wellness and work limit Improved cognizance Increased resistance Lower bleakness from irresistible ailment

Preschool kids School age youngsters and teenagers Non-pregnant ladies Pregnant ladies Adult men

Epidemiologic Revolution 1960s-1980s Risk elements for endless ailment Health field idea Health for All Declining mortality from stroke and CHD, injury Advances in medications and diagnostics Control of irresistible sicknesses Rapid increment in expenses of care: wellbeing framework change

Nutrition Interactions Iodine Deficiency – psychomotor hindrance Iron Def Anemia and irresistible illnesses Iron advances development and advancement Vitamin An and irresistible ailments e.g. measles Vitamin An advances development Folic corrosive counteracts birth surrenders Folic corrosive with CVD, Alzheimer's Disease Nutrition and malignancy Nutrition and cardiovascular sickness Nutrition and diabetes Nutrition in illness administration

Folic Acid and Heart Disease High homocysteine levels related with overabundance CHD, birth imperfections, Alzheimer's Disease Folic corrosive decreases high homocysteine Flour stronghold viable in bringing FA step up in populace Clinical trials of folic corrosive and CHD in progress New worldview in general wellbeing sustenance

Osteoporosis Aging of the populace Vit D creation in skin occasional Sun changes via season and scope even in sunny nations Fortification of calcium advanced Vitamin D ailing in crude drain Calcium, vitamin D, fluoride co-elements Fortifying milk items with Vit D required
