We all know our lifestyle habits impact both our physical and mental health. But, what are the proofs? According to a new study led by Harvard School of Public Health, maintaining five healthy habits—eating a healthy diet, exercising regularly, keeping a healthy body weight, not drinking too much alcohol, and not smoking—during adulthood may add more than a decade to life expectancy. Yes, A DECADE MORE! Not to mention a much higher quality of life during these years!
Researchers also found that U.S. women and men who maintained the healthiest lifestyles were 82% less likely to die from cardiovascular disease and 65% less likely to die from cancer as compared with those with the least healthy lifestyles over the course of a roughly 30-year study period.
This study is the first comprehensive analysis of the impact of adopting low-risk lifestyle factors on life expectancy in the U.S. It was published online April 30, 2018 in Circulation (1).
Americans have a shorter average life expectancy—79.3 years—than almost all other high-income countries. The U.S. was ranked 31st in the world for life expectancy in 2015. The new study aimed to quantify how much healthy lifestyle factors might be able to boost longevity in the U.S.
Harvard researchers and colleagues looked at 34 years of data from 78,865 women and 27 years of data from 44,354 men participating in the Nurses’ Health Study and the Health Professionals Follow-up Study respectively. The researchers looked at how five low-risk lifestyle factors— (i) not smoking, (ii) low body mass index (18.5-24.9 kg/m2), (iii) at least 30 minutes or more per day of moderate to vigorous physical activity, (iv) moderate alcohol (for example, up to about one 5-ounce glass of wine per day for women, or up to two glasses for men), and (v) a healthy diet—might impact mortality.
For study participants who didn’t adopt any of the low-risk lifestyle factors, the researchers estimated that life expectancy at age 50 was 29 years for women and 25.5 years for men. But for those who adopted all five low-risk factors, life expectancy at age 50 was projected to be 43.1 years for women and 37.6 years for men. In other words, women who maintained all five healthy habits gained, on average, 14 years of life expectancy and men who did so gained 12 years as compared with those who didn’t maintain healthy habits.
Further, when compared with those who didn’t follow any of the healthy lifestyle habits, those who followed all five were 74% less likely to die during the study period. The researchers also found that there was a proportionate relationship between each individual healthy lifestyle behavior and a reduced risk of early death, and that the combination of all five healthy behaviors was linked with the most additional years of life.
At Karviva, we encourage everyone to adopt a healthy lifestyle via compassion to yourself as well as others. By living a healthy lifestyle, you will inspire others through how you look and how you act. We believe a healthy diet should emphasize balanced, nutrient -dense superfoods rather than paying attention to transient diet fads.
