About this symptom
Food Aversion
A large majority of women will experience some kind of food aversion during pregnancy, and very often in the first trimester. Food aversions may have many causes, including hormonal changes, increase sense of smell and nausea. Some experts believe some aversions are the result of the body attempting to protect the fetus by preventing the mother from eating foods that may be contaminated with food bourne pathogens such as seafood, or preventing them from eating or drinking unhealthy foods like coffee and alcohol. Although many women also experience aversions to healthy foods such as protein and vegetables. These aversions generally diminish after the first trimester but may not completely disappear until the baby is born.
