The role of iron in oxygen transport is well understood. The absorption, transport, storage and excretion of iron need to be taken into account when considering the development of iron deficiency and iron overload. Iron requirements vary widely at different stages of life.

Learning goals:

• Iron-containing proteins.
• Iron balance and status
• Sources in food: requirements.
• Reasons for and results of iron deficiency and iron overload.
