Researchers identify neuronal mechanisms that control food cravings during pregnancy

Many people have felt the sudden and uncontrollable urge to eat a certain food. These urges --known as cravings-- are very common, especially during pregnancy. During this time, the mother's body undergoes a series of physiological and behavioral changes to create a favorable environment for the embryo's development. However, the frequent consumption of tasty and high calorie foods -- derived from the cravings -- contributes to weight gain and obesity in pregnancy, which can have negative effects on the baby's health.
