Washington: Scientists took 4D ultrasound scans of 100 pregnant women to see how their unborn babies responded to flavours from foods eaten by their mothers. The research team scanned some mothers to see fetal facial reactions to the kale and carrot flavours. A study led by Durham University's Fetal and Neonatal Research Lab, UK, took 4D ultrasound scans of 100 pregnant women to see how their unborn babies responded after being exposed to flavours from foods eaten by their mothers.
Researchers looked at how the fetuses reacted to either carrot or kale flavours just a short time after the flavours had been ingested by the mothers. Fetuses exposed to carrot showed more "laughter-face" responses while those exposed to kale showed more "cry-face" responses. Their findings could further our understanding of the development of human taste and smell receptors.
