IDA is the final stage of different processes, where two main (which
finally affect iron balance) causes can be identified: Inadequate iron
supply and Abnormal Iron looses
a) Inadequate iron supply can be due to poor iron content in the diet or due to diets with insufficient bioavailable Iron (presence of inhibitors of iron absorption or low level of enhancers).
During the periods of life with rapid growth rates and with high requirements, as infancy, early childhood, adolescence or pregnancy, it is likely to occur a negative balance, which can lead to ID.
Sources of dietary iron have been discussed earlier, as well as the role played by different constituents of the diet modifying iron absorption. Having discussed these interactions it is possible to know that iron bioavailability will be higher in a mixed diet taken with orange juice than one taken with tea.
