People who drink a little, exercise, give up
smoking and eat five servings of fruit and vegetables each day live on average
14 years longer than people who have none of these behaviors, researchers said
on Tuesday . A collection of evidence has shown that these things contribute to
healthier and longer lives, but the new study actually proved their mixed
effect, the British team said.
“These results may provide further support for the idea
that even small differences in lifestyle may make a big difference to health, ” the researchers
wrote in the journal PLOS Medicine.
Between 1993
and 1997 the researchers questioned 20，000 healthy British men and women about their
lifestyles. They also tested every participant’s(參與者) blood to measure vitamin C intake, an
indicator（指標(biāo)）of how much fruit and vegetables people ate.
Then they
assigned(分配,分派)the participants---aged 45-79 a score of between 0 and 4，giving
one point for each of the healthy behaviors. After allowing for age and other
factors(因素) that could affect the likelihood of dying, the
researchers found people with a score of 0 four times as likely to die.
The
researchers, who tracked deaths among the participants until 2006，also
said a person with a health score of 0 had the same risk of dying as someone
with score of 4 who was 14 years older.
The lifestyle
change with the biggest benefit was _____________________ ,which led to an 80
percent improvement in health, the study found. This was followed by eating
fruits and vegetables. Drinking a little and keeping active brought the same
benefits, Kay-Tee Khaw at the University of Cambridge said. Do you have the
four healthy living habits?
