Definition: A blood condition with an abnormal reduction in red blood cells or haemoglobin.
Causes:

- Folic Acid deficiency (found in orange juice and liver)
- Iron deficiency (poor absorption, medication, diarrhea, intestinal disease)

- Chronic kidney disease
- Smoking (women)

Plant Sources of Iron

Non-heme iron
Found in whole grains, cereals
Absorption affected by phytates, tannins, oxalates (found in certain vegetables)
Calcium reduces absorption of non-heme iron.

Animal Sources of Iron

Heme iron
Found in red meat, offal
Absorption rate is relatively low compared to non-heme iron

Tiredness

Headaches
Loss of appetite
Shortness of breath
Pale skin
Thirst
Irritability

Treating Anemia

Nutritional supplements (iron)
Medical procedures (serious cases)
Well-balanced diet
