According to Mary Roach in her book "Gulp: Adventures on the Alimentary Canal," both breast milk and amniotic fluid contain flavors influenced by the mother's diet. This direct connection enables infants to experience various tastes even before they are born. As a result, flavors they are exposed to during pregnancy and breastfeeding can shape their palate later in life.

Research suggests that this early exposure helps babies develop a more accepting attitude towards the diverse flavors they encounter as they grow. Thus, the tastes experienced in utero and through breast milk can play a significant role in influencing children's future food preferences.
