Babies in the womb smile at carrots, cry at cabbage
It is already known that babies react negatively to cabbage. Researchers at the University of Durham have now found out how early this aversion begins.
Already in womb According to a study, babies react positively or negatively to certain foods.
Fetuses would have shown a more "smiling face" after their mothers carrots ate, scientists from the University of Durham in north-east England report in the journal "Psychological Science". After enjoying cabbage flavors, on the other hand, the fetuses would have made a more "crying face".
It was well known that babies dislike cabbage. However, evidence has now been found for the first time that even fetuses reacted differently to different smells and tastes in the womb, according to the study. The fetuses probably develop taste when they inhale and swallow amniotic fluid in the womb.
4D ultrasound images
The researchers used 4D ultrasound to record the facial expressions of their babies in 100 women at 32 and 36 weeks of pregnancy. the mothers received a capsule containing around 400 milligrams of carrots or 400 milligrams of cabbage powder about 20 minutes before the scan and also did not eat anything that contains flavor for an hour beforehand. Fetal facial responses were compared to those of a control group that received neither carrots nor cabbage. Result: Even small amounts flavored with carrots or cabbage were enough to trigger a reaction.
Co-author Jackie Blissett of Aston University in Birmingham said repeated prenatal taste exposure could lead to food preferences after birth. "In other words, exposing the fetus to less 'popular' flavors, like cabbage, could mean becoming accustomed to those flavors in utero."
