4. Iron Requirements of Elderly
30 mg of iron is required for
elderly female and 38mg
of iron is required to meet
the daily requirements
of body.

5. Healthy Hemoglobin Levels
Age Group Healthy hemoglobin level
(Hb g/dl)
Children (5-11 years) >11.5
Children (12-14 years) >12
Girls and women (>15
years)
>12
Boys and men (>12 years) >13
Pregnant women >11

10. Classification of Anemia
• Etiologic classification :
 Blood loss
 Poor diet
 An inability to absorb enough iron from food.
• Morphologic classification:
 Macrocytic anemia
 Microcytic anemia
 Normochromic normocytic anemia

11. Etiologic classification:

13. Morphologic anemia
Microcytic Macrocytic Normocytic
Iron deficiency Megaloblastic anemia-B12
or folic acid deficiency
Hemolytic anemia
Thalassemia Non-megaloblastic anemia Acute blood loss
Anemia of chronic disease Mixed deficiency
Lead poisoning
Sideroblastic anemia

18. TYPES OF IRON
There are two types of iron in food:
 Heme iron, derived from the hemoglobin and
myoglobin found in meat tissue
 Non-heme iron, derived mainly from cereals,
legumes, fruit and vegetables.

19. HEME IRON
 Heme iron is found only in animal foods. The iron in
meat is approximately 40% heme iron and 60% non-
heme iron. Plant foods do not contain any heme iron .
 Heme iron is well absorbed and relatively
unaffected by other factors .
 It is influenced to some extent by the body’s iron
stores.The average absorption of heme iron in meat is
about 25%.

20. NON-HEME IRON
 Non-heme iron is found in plant foods.
 It is not as well absorbed as heme iron and is affected
by both the iron status of an individual, and components
in foods eaten at the same time.
 Absorption of non-heme iron can vary from under 1% in
an individual with replete stores to 20% in an individual
with depleted iron stores .
 Generally non-heme iron absorption is less than 5%.

22. Absorption of iron
• Heme iron is absorbed better than non-heme iron,
and its absorption is not affected by other things
you eat. You absorb 15-35% of the heme iron you
eat!
• Non-heme iron is not absorbed by the body as
well as heme iron. Only 2-20% of
non-heme iron is absorbed because
many factors hinder the absorption
of non heme iron
