Most women get cravings at one time or another.
Sometimes, it means your body is needing something nutritionally so by craving a certain food, you'll satisfy that need. Normally, just go ahead and satisfy your craving. You'll feel better.

Eating too much of one thing doesn't allow you to fullfill all of your nutritional needs.
