Consuming large amounts of liquorice while pregnant can increase the risk of delivering the baby prior to full-term, according to scientists from the University of Helsinki , in Finland. In a report, published in the June issue of American Journal of Epidemiology (2001; p153: pp1085-1088), the researchers explained that pregnant women who ate at least 250g of black liquorice every week were over twice as likely to go into labour before 38 weeks, an average of 2.5 days earlier than women who ate little or no liquorice.
