"Healthy Med diet can extend life", BBC News, April 8, 2005,

Scientists have produced powerful evidence that a Mediterranean diet
rich in vegetables and fruit and low in saturated fats can help us live
longer.
It has long been thought that the diet can help to improve general
health.
But a major pan-Europe study of 74,607 men and women aged over 60 has
shown closely following the diet can actually extend life by up to one
year.
The study, led by University of Athens Medical School, is published in
the British Medical Journal.
The researchers collected information on areas including diet,
lifestyle, medical history, smoking and physical activity.
The men and women were each given a score based on adherence to a
Mediterranean diet, with higher scores for those who ate the most foods
linked to such a diet.
The researchers found that overall a higher dietary score was linked to
a lower overall death rate.
They said that a two-point increase in the score was linked to an 8%
reduction in mortality.
A three-point increase was associated with an 11% drop in mortality and
a four-point increase was associated with a 14% drop.
This meant that a healthy man of 60 who stuck closely to a
Mediterranean diet could expect to live around one year longer than a
man of the same age who did not eat such a diet.
The researchers said the link was strongest in Greece and Spain -
probably because people in these countries followed a genuinely
Mediterranean diet.
UK lagging behind
Rebecca Foster, a nutrition scientist at the British Nutrition
Foundation, said diets in the UK were not as healthy as those followed
by many of their European counterparts.
"Although dietary surveys indicate that we are eating fewer calories,
less total fat and we are beginning to see a reduction in salt intake,
we are still not meeting the UK dietary guidelines, which are in line
with the characteristics of the Mediterranean diet.
"In particular, the Mediterranean countries such as Spain and Greece
eat a lot more fruit and vegetables and have a lower intake of
saturated fat."
However, she said the study findings could in part be down to genetic
factors, rather than simply diet alone.
Belinda Linden, of the British Heart Foundation, said: "Dietary studies
are often difficult to carry out as it is hard to define which
constituent of the diet provides the most benefit.
"But that should not put us off trying - it is vital that large and
in-depth dietary studies such as these are carried out to further our
understanding of the way different diets affect our health.
"This study adds detailed evidence to previous findings and confirms
that this type of diet, containing all the essential components of the
Mediterranean diet, can be linked with prolonged life.
"Importantly, however, the diet is only one part of lifestyle change
needed to reduce coronary heart disease and we must also aim to
increase our activity levels, control our weight and stop smoking."
