REQUIREMENTS AND ALLOWANCES
Iron requirements spring from:
- Basal losses
- Menstrual losses (large variations, oral contraceptives decrease loss, intrauterine device increase loss)
- Growth (linear growth, pregnancy)

Traditionally, some groups would receive more iron from their diet than others, e.g. as a result of their occupation or status.
[Ref 16]
In Norway the basal iron requirements for most population groups can now be met through a varied diet.
