It is also required for the formation of haemoglobin. This is present in red blood cells and helps them transport oxygen around the body.
Sources
There are two types of iron – haem and non-haem.
Haem iron comes from animal sources, which are more easily absorbed by the body. These include:
red meat
liver
eggs
fish
Non-haem iron comes from plant sources, and is more difficult for the body to absorb. In fact, it needs vitamin C to help absorption. Sources of non-haem iron include:
green leafy vegetables – such as broccoli and cabbage
fortified breakfast cereals
wholegrains
Deficiency
Iron deficiency is called anaemia. This is common in teenage girls as they begin menstruation.
