I don't think that this is the reason. The gluten in grains and casein in
milk (and sugar and all the rest) have made it a probability that iron will
either go dangerously up - hemochromatosis, or down - anemia. (in a nutshell)

 It is now considered a good idea for men to donate blood
>occasionally to reduce their iron levels.

A good paleo diet will help and is less invasive.

All the best,
