Harvard researchers analyzed how different aspects of a healthy lifestyle affect the expected lifespan (Life Excpeccy). The most effective measures were healthy nutrition, regular physical activity, unfortunate smoking, as well as body weight control and alcohol consumed. Work is published in the Circulation Journal.
Scientists analyzed the data of two long-term research: Nurses’ Health Study and Health Professionals Follow-Up Study. 123 219 medical workers took part in them, they regularly passed the inspections of specialists for three decades.

For those who did not comply with any of the rules, the life expectancy was an average of 76 years (in men) and 79 years old (in women). Those who adhered all five principles, this period was 87 and 93 years old, respectively. According to scientists, supporters of a healthy lifestyle by 82% less often died from cardiovascular diseases and 65% less often – from cancer.
