Extreme iron deficiency can cause anemia. Women are more prone to iron deficiency because of the loss of blood through menstruation. Because iron can also be lost through perspiration, athletes can also be subject to low iron. It is also known that the excessive consumption of tea or coffee can inhibit the absorption of iron by the body. I wonder what's considered excessive these days, what with a coffee shop on almost every corner - yikes! That might be a small exaggeration, but I imagine we probably consume more coffee and tea than ever before.
