Fetuses apparently like carrots, but kale? Not so much, ultrasounds show

Fetuses are big fans of carrots but not leafy green vegetables -- and show it in their faces, scientists said in a new study published Thursday.

Researchers at Durham University in northeast England said the findings were the first direct evidence that babies react differently to various smells and tastes before they are born.

A team of scientists studied 4D ultrasound scans of 100 pregnant women and discovered that babies exposed to carrot flavors showed "laughter-face" responses.
