In a study, mothers ranging from the thirty-second to the thirty-sixth week of gestation participated, and one of the foods they were given to eat was kale. Their babies didn’t seem to enjoy this choice though since they would raise the upper lip, press both lips, and make crying faces. The scientists used 4D ultrasound scans to capture the fetuses’ reactions, and they couldn’t be more clear about their feelings about kale.

When the mothers were given carrots and carrot juice, the babies showed a completely different reaction. They would pull the corners of their lips and make a laughing face, something that showed they were enjoying the taste. This distinction between flavors was all the proof scientists needed to show that fetuses do understand different flavors from the belly.

The reason they think carrots were more favorable is because of their sweeter taste. It’s higher in sugar content, and it can sometimes feel like it has a “fruity” taste. On the other hand, kale is more bitter and that is solely the reason it was chosen for this experiment.
