New study finds too much black licorice during pregnancy could affect a baby’s brain.

Babies who mothers ate the most licorice while pregnant had lower IQs than the children whose mothers ate little to no licorice during their pregnancy, according to the study, which was published in the American Journal of Epidemiology.

In addition, girls born to mothers who consumed high amounts of licorice during pregnancy reached puberty earlier than those born to mothers who ate little to no licorice, the researchers found.

“The present findings suggest that pregnant women should be informed that consumption of licorice and other food products containing [a chemical found in licorice called] glycyrrhizin may be associated with harm for their developing offspring,” the researchers wrote in the study, which was led by Katri Räikkönen, a professor of psychology at the University of Helsinki in Finland.

Glycyrrhizin blocks the activity of an enzyme that helps protect the fetus from high levels of cortisol, which is sometimes referred to as the stress hormone. High levels of cortisol may affect the neurological development of a fetus, the researchers wrote.

The researchers noted, however, that they could not determine in the study a specific cut-off amount for how much licorice is safe for a pregnant woman to eat, or if there was a specific time during pregnancy that women should avoid the candy.

In addition, the researchers cautioned that licorice may not be the only factor in the study that affected development. It’s possible that other, unmeasured factors may have played a role, they said.

  • Could is the key word in this article. The article and the study seem to contradict the claims? I am somewhat perplexed – this seems quite confusing. There are so many factors in all of these studies and without all of the details they can cause more alarm than good.

  • Another good reason not to eat licorice is it tastes nasty

  • Don’t know if this study is very trustworthy, but I can imagine licorice/ any form of candy is not the type of food you want to eat when pregnant as a healthy diet is important especially at that time.

  • I wonder how much research was actually done and over how many years. Was it US wide or only 1 or 2 states?

  • An interesting article, and if I were pregnant I’d avoid licorice because of the study. These studies are not always 100% correct though.
