Slide6Human MalnutritionMarasmusEnergy and protein deficiency Kwashiorkior
Deficiency of protein (quality or quantity)
Goiter
Iodine deficiency
Anemia
Deficiency of iron, vit. B12, or folic acid
Slide7Kwashiorkor
Slide8Preparation of Casava
Slide9H. H. Stein
Nutritional Value of Casava
Slide10Kwashiorkor
Slide11Protein RequirementsIs a requirement for indispensable AA
AA are needed for maintenance, growth, and milk protein synthesis
Greatest requirement (as % of diet) in children, teenagers, and pregnant and lactating women
No storage of excess AA – needed every day
