You get Cravings for Non-Food Sources
Pica is a disorder that causes a person to crave things that are not food. It often occurs in people who are iron-deficient. Pregnant women may also experience pica. Some of the things that you may crave if you have pica include dirt, ice, paint and clay. The reason that you experience unusual cravings when you are iron-deficient is because your body is trying to replenish the nutrient.
