Sticking with five well-known behaviors, eating a plant-rich diet, exercising regularly, keeping weight in the healthy range, limiting alcohol and never smoking, does more than prolong life. It pushes back the onset of the big three chronic illnesses (heart disease, type 2 diabetes and cancer) by almost a decade for women and about eight years for men after the age of 50.
Harvard researchers followed more than 111 000 U.S. adults for up to 34 years. Each extra healthy habit raised the odds of living longer without those diseases; meeting four or five habits delivered the biggest benefit. Women who embraced them enjoyed roughly 34 disease-free years after 50 versus 24 for their peers with no healthy habits. For men the comparison was 31 versus 23 years.
No single habit dominated, the gains were additive, so adopting even one or two habits still helped. Because participants began the study at age 30 or older, the authors stress that “it’s never too late to change.” Beyond personal benefit, more years spent healthy could cut healthcare costs for whole populations.
Healthy lifestyle and life expectancy free of cancer, cardiovascular disease and type 2 diabetes: prospective cohort study – BMJ Study, 8 January 2020
Researchers analyzed two long-running U.S. cohorts and found that, at age 50, adults who adhered to four or five low-risk lifestyle factors could expect 8–11 extra years of life free from the major chronic diseases compared with those meeting none.

Earlier work by the same team showed the five habits could extend overall life expectancy by 12–14 years, highlighting their long-term impact.
