asynchronous week 5 micronutrient malnutrition

describe and evaluate factors related to iron deficiency: how much we need, dietary sources, who is at risk, consequences, how can we detect

how much needed:

dietary sources: liver, beef, pork, blood, dried beans fruits, iron fortified foods (cast iron), spinach

who is at risk: children, mothers

consequences: children’s learning, premature birth, maternal deaths, lowers productivity = loss of GDP

how can we detect: biochemical blood test etc, clinical pale conjunctiva

identify describe and evaluate strategies that could reduce iron deficiency and improve iron status

change diet to increase iron intake and absorption

• iron in animal tissue

  • 40% heme 60% non heme

• iron in plant foods

  • 100% non heme

• HEME more absorbable

• vitamin C

fortification

• add iron to wheat flour

• micronutrient powder MNP packets

control hookworm

• wear shoes

identify and justify WHO reccomendations for zinc supplementation during acute diarrheal episodes in children; evaluate one approach to increase adherence to this reccommendation in rural Zambia

10-14 days zinc supplementation

• piggy backig on coca cola supply chain to get ORS and zinc into rural zambia

• the actual success came from an effective value chain, not promoted through coke distribution

describe causes and consequences of iodine deficiency at different stages of life

pregnancy: leads to 20 million infacts per year born with cognitive and growth impairments

children: cretinism (stunted physical and mental growth)

goiter: swelling of thyroid gland 90% caused by iodine deficiency

describe and evaluate the impact of fortification as a strategy to reduce the global prevalence of iodine deficiency

iodine in table salt (only ¾ of the world using it)

• fortification programs aren’t always mandatory

• levels of fortification may vary

Uk has never regulated iodization of salt and it is limited
