When it comes to tongues, melting chocolate is better than a passionate kiss, BBC News Online reports scientists as having found.
Couples in their 20s had their heart rates and brains monitored while they first melted chocolate in their mouths and then kissed.
Chocolate caused a more intense and longer lasting “buzz” than kissing, and nearly doubled volunteers’ heart rates.
Dr. David Lewis, formerly of the University of Sussex, and now of the Mind Lab, carried out the research.
“There is no doubt that chocolate beats kissing hands down when it comes to providing a long-lasting body and brain buzz,” Lewis said. “A buzz that, in many cases, lasted four times as long as the most passionate kiss.”
He said substances in chocolate were already known to have a psychoactive effect, but that allowing it to melt on your tongue could be the secret to maximizing the buzz.
Although kissing set the heart pounding, the effect did not last as long as that seen with the chocolate, which increased heart rates from a resting rate of about 60 beats per minute to 140.
The study also found that as the chocolate started melting, all regions of the brain received a boost far more intense and longer lasting than the excitement seen with kissing.
The researchers used 60 per cent cocoa dark chocolate.
