The New Scientist reports on a Finnish study that seems to show consumption of chocolate by pregnant mothers makes for happier babies. The BBC adds a more cautionary note: “Nigel Denby of the British Dietetic Association [...] warned mums-to-be against over-indulging in chocolate. ”

The lead researcher Karti Raikonnen of the Dept. of Psychology with the University of Helsinki, has done previous work on the psychology of well-being, relating to risk factors for heart disease. So does the stress relief from chocolate consumption make up for the risks from extra fat?
