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.
It should be noted that it is also possible to consume too much iron; toxicity levels begin at about 45 milligrams per day. In an average diet it is very unlikely that cooking with cast iron will bring a person to this level. Low iron is more likely to be a problem, and cooking with cast iron can be less expensive and more fun (at least more hunger satisfying!) than taking iron supplements. If you do use cast iron you should consult your doctor before taking other iron supplements.
Cast iron is much beloved by serious chefs, and lasts nearly forever if you take care of it. Seasoning cast iron cookware is necessary to ensure a non-stick surface and to prevent the pot or pan from rusting. If seasoned correctly your cookware can last a lifetime and more.
