Fetuses in the womb scowled after their mothers ate kale but smiled after they ate carrots, according to a new study of around 100 pregnant women and their fetuses in England.
The study offers a rare look at how fetuses respond to flavors in real time.
The researchers gave the participating women capsules containing powdered versions of the two foods. Thirty-five women consumed the equivalent of one medium carrot, and 34 women consumed the equivalent of 100 grams of chopped kale. The remaining 30 women didn’t consume either.
