Four-dimensional ultrasound has proven that people react to taste and smell even in the womb.

The study involved a hundred women at 32-36 weeks of pregnancy. On the day of the study, the women were not allowed to eat or drink flavored beverages before visiting the doctor. 20 minutes before the scan, they received a capsule of carrot or cabbage powder. After that, doctors took pictures of the facial expressions of as yet unborn children. Scientists believe that the mother's diet during pregnancy can affect the taste preferences of children. Also, the right diet of a woman is able to form healthy eating habits for a child.
