For years studies have shown a link between a woman’s licorice consumption and lower IQs in their offspring.
The problem is thought to originate with the compound glycyrrhizin that is found in licorice.
A recent Finnish study has confirmed that finding, and has also linked licorice consumption during pregnancy to an increased risk of children developing Attention Deficit Hyperactivity Disorder (ADHD).
On average, a mother’s high consumption of licorice reduced a child’s IQ by seven points. It also tripled the risk for the child developing ADHD, and in girls, led to an earlier onset of puberty.
