British researchers said Monday they were stunned to discover that people get more of a buzz from eating chocolate than passionately kissing their lovers.
"These results really surprised and intrigued us," said
psychologist David Lewis, who led a study that recorded brain
activity and heart rate from volunteers who tasted pieces of dark
chocolate or kissed their partners.
Beats kissing hands down
"There is no doubt that chocolate beats kissing hands down when
it comes to providing a long-lasting body and brain buzz - a buzz
that, in many cases, lasted four times as long as the most
While researchers expected chocolate, especially dark chocolate,
to raise heart rates, he said, "both the length of this increase
together with the powerful effects it had on the mind were
something none of us had anticipated."
The 12 volunteers, all aged in their 20s, wore heart monitors
and had electrodes attached to their heads as each placed a piece
of dark chocolate on the tongue and, without chewing, indicated
when it started to melt.
Couples were later invited to kiss each other in the same way as
they would do normally.
The study found that - at the point chocolate melts in the
mouth - all areas of the brain are stimulated far more intensely
and for longer than from kissing.
Made the heart beat faster
Chocolate also made the heart beat faster, according to the
study supervised by Lewis, a former University of Sussex
psychologist who now runs a private research company called The
Some people saw the number of heart beats per minute rise from a
resting rate of about 60 to as high as 140. Kissing also made the
couples' hearts pound, but not for as long.
Both sexes showed the same responses in the tests. – (Sapa-AFP)
