people who drink a little, exercise, quit smoking and eat five servings of fruit and vegetables each day live on average 14 years longer than people who adopt 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 qualified 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 blood to measure vitamin C intake, an indicator（指标）of how much fruit and vegetables people ate.

Then they assigned 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 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 a health 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?
