Durham University study links prenatal flavor exposure to childhood taste preferences

Researchers at Durham University have found that a child's future flavor preferences may be influenced by the food consumed by their mother during pregnancy. The study suggests that flavors and aromas from maternal diet can reach the fetus through amniotic fluid, which the unborn baby swallows.

In the study, pregnant women were given capsules containing carrot or kale powder. Researchers observed subtle differences in fetal facial expressions in response to these flavors via ultrasound. Follow-up observations of the children at age three showed that those exposed to carrot during pregnancy tended to react more positively to the scent of carrots and less to kale, while the opposite was true for those exposed to kale in the womb. Lead researcher Nadja Reissland suggests this may indicate an early memory of tastes or smells, making certain flavors more familiar to the child later in life.
