Totally not true. An iron deficiency would make you weak and lightheaded among other things...Not make you want to crunch ice.

I was told that cruching on ice is a sign that you are sexually frustrated. I am not. I don't think that is true.

Actually, it is true - but not for everyone. Some people chew ice because they are nervous or just want something crunchy. But in some instances, anemic individuals will chew ice - its a condition called pica. Some people with pica even crave dirt. It's a very strange, yet fascinating condition.

This is actually true! I just found out a week ago that I had Iron defienciency Anemia. I am truelly addicted to ice so I decided to do the research and this condition is known as pica, a "disorder" associated with anemia.
