Why do I crave ice?

Craving ice is a common symptom for iron-deficiency anemia, according to NationalHealthMag.com. The urge to eat substances that offer no nutrition, such as ice or dirt, is an eating disorder known as pica. Ice chewing is a form of pica due to anemia, meaning a lack of red blood cells.

There is little evidence as to why iron-deficiency anemia leads to ice cravings, but medical attention is recommended. Doctors can diagnose the disorder through a blood test.

The solution to iron-deficiency anemia is to take iron supplements. Iron can be difficult to acquire from food alone once anemia is present. Examples of foods that contain iron are spinach, soy and pumpkin.
