What kings of food cravings are normal?
Many pregnant women crave sweet or salty foods. Cravings for non-food items such as dirt, soap, ash, or coffee grounds are different. A phenomenon called pica, which has shown up in medical literature since the sixth century, results in strange cravings that can cause serious problems for a pregnant mother and her un-born baby. If you have a craving to eat clay, ashes, laundry starch, or other unusual substances, seek medical attention right away.
