Babies 'taste' the food their mothers consume from the womb

A study published in the latest issue of Psychological Science shows that between 32 and 36 weeks, fetuses smile or frown in response to the food their mother eats.

Based at Durham University's Fetal and Neonatal Research Laboratory, the study's research team used 4D ultrasound scans, which create three-dimensional videos of fetuses in the womb, to see how the unborn children of 100 pregnant women reacted to food consumed by their mothers.

Depending on the food, some fetuses responded with pursed lips and "laughing" expressions, while others had "crying" facial expressions.

Senses and facial expressions develop throughout pregnancy

Taste buds appear at eight weeks of gestation in human fetuses and can detect taste molecules in amniotic fluid around week 14. In the 24th week, fetuses also develop their sense of smell.

Meanwhile, the fetus's facial muscles are developing and their facial expressions become increasingly complex during pregnancy. From the second trimester, their expressions resemble the smiles and frowns they will make after giving birth.

Food choices during pregnancy can influence the future preferences of the baby

This study is the first to prove that fetuses still in the womb react to different tastes and smells.

Not only do these results give us a better understanding of the timeline for fetal sensory development, but they also show that the mother's diet during pregnancy is one way babies are introduced to new tastes, which can have a long-term impact on the child's nutrition. preferences. A baby who enjoys kale quite often in the womb may be less likely to reject it when it is fed after birth.
