For many women, cravings during pregnancy are normal. Cravings for particular foods during pregnancy can be both good and bad. If you crave foods that are nutritious and healthy, eat them in moderate amounts. If you crave foods that are high in sugar and fat, and loaded with empty calories, be very careful about eating them.
No one knows why some women develop cravings during pregnancy, especially cravings for foods they might not normally eat. But many believe it is because of the hormonal and emotional changes that occur during pregnancy. It's not uncommon during pregnancy to be nauseated by foods you love to eat normally.
The hormones of pregnancy have a significant impact on the gastrointestinal tract, which can affect your reaction to certain foods.
