It is common for athletes - especially runners - to be diagnosed with iron-deficiency anemia. But why does that matter and what do you do now?
What
Is It?
Iron is a trace
mineral that the body needs to obtain from food for proper function of key
biological processes. Iron carries oxygen in the blood and delivers it to the
lungs and muscles. It is also important for the proper function of the immune
system. Each red blood cell that you have in your body contains a protein
called hemoglobin (what gives red
blood cells their color) that iron is attached to.
Why
Do I Need It?
Getting the
right amount of iron is important because it determines how much oxygen gets to
the rest of the body. If iron is low, the body starts making fewer red
blood cells—leading to fatigue, feelings of coldness, decreased physical
performance and anemia. Both vegetarian and female athletes are at an increased
risk of developing iron deficiency anemia.
