Want to live longer? Don't smoke. Eat 5 servings of vegetables and fruits daily. Get moderate exercise. Drink between 1 and 14 glasses of wine or half pints of beer per week. A study of over 25,000 people in Norfolk county UK published in Plos Medicine found that people who smoke, do not get enough fruits and vegetables, do not get enough exercise, and do not drink moderately die 14 years sooner on average than people who are the opposite on these lifestyle characteristics.
What Did the Researchers Do and Find?
Between 1993 and 1997, about 20,000 men and women aged 45–79 living in Norfolk UK, none of whom had cancer or cardiovascular disease (heart or circulation problems), completed a health and lifestyle questionnaire, had a health examination, and had their blood vitamin C level measured as part of the EPIC-Norfolk study. A health behavior score of between 0 and 4 was calculated for each participant by giving one point for each of the following healthy behaviors: current non-smoking, not physically inactive (physical inactivity was defined as having a sedentary job and doing no recreational exercise), moderate alcohol intake (1–14 units a week; a unit of alcohol is half a pint of beer, a glass of wine, or a shot of spirit), and a blood vitamin C level consistent with a fruit and vegetable intake of at least five servings a day. Deaths among the participants were then recorded until 2006. After allowing for other factors that might have affected their likelihood of dying (for example, age), people with a health behavior score of 0 were four times as likely to have died (in particular, from cardiovascular disease) than those with a score of 4. People with a score of 2 were twice as likely to have died.
What Do These Findings Mean?
These findings indicate that the combination of four simply defined health behaviors predicts a 4-fold difference in the risk of dying over an average period of 11 years for middle-aged and older people. They also show that the risk of death (particularly from cardiovascular disease) decreases as the number of positive health behaviors increase. Finally, they can be used to calculate that a person with a health score of 0 has the same risk of dying as a person with a health score of 4 who is 14 years older.
A Danish study also published today found the same benefits from moderate alcohol and moderate exercise in over 11,000 Danes.
People who drink moderate amounts of alcohol and are physically active have a lower risk of death from heart disease and other causes than people who don’t drink at all, according to new research. People who neither drink alcohol nor exercise have a 30-49 per cent higher risk of heart disease than those who either drink, exercise or both.
The research, which was published in the European Heart Journal  today (Wednesday 9 January), is the first to look at the combined influence of leisure-time physical activity and weekly alcohol intake on the risk of fatal ischaemic heart disease (a form of heart disease characterised by a reduced blood supply to the heart) and deaths from all causes.
Between 1981-1983 Danish researchers obtained information on various health-related issues (including exercise and alcohol intake) from 11,914 Danish men and women aged 20 or older, who were taking part in the larger, Copenhagen City Heart Study.
Want to do more? Add some fish for an added health benefit. Eat even more than 5 servings of fruits and vegetables per day and some nuts too. Also, reduce your red meat consumption and lower your dietary glycemic index.
