Rich sources of Iron



Causes of iron deficiency are : 
  • Reduced iron intake in food : Regular consumption of food that is low in iron content leads to deficiency of iron. This food can be low in iron content or may be containing low quality iron in food. The iron from meat is heme iron and it is absorbed better from food that non heme iron like that from plant and vegetable sources.
  • Inability to absorb iron from food : 
  • If food contains excessive tanins, caffeins then iron can not be absorbed into blood.
  • Food containing excess animal leads to reduced absorption of iron in blood leading to iron deficiency anemia.
  • Certain rare disease conditions that are genetic, the affected persons can not absorb iron from food to blood.
  • Increased need of iron in certain conditions like puberty, pregnancy : These conditions lead to increased need of iron to meet the increased demand of body. If iron storage in body is inadequate or food without inadequate iron content is taken then it leads to iron deficiency anemia.
  • Increased loss of iron like chronic loss of blood in stool, heavy menstruation, chronic epistaxis : 
  • ​Chronic blood loss in stool : like in worm infection, menstruation.
