Could An Unhealthy Diet and Lack of Exercise Make Us Age Faster?

Researchers at Mayo Clinic believe there is a link between these modifiable lifestyle factors and the biological processes of aging. In a recent study, researchers demonstrated that a poor diet and lack of exercise accelerated the onset of cellular senescence and, in turn, age-related conditions in mice. Results appear today in Diabetes.

Senescent cells are cells that contribute to diseases and conditions associated with age. Researchers from the Mayo Clinic Robert and Arlene Kogod Center on Aging found that exercise prevents premature senescent cell accumulation and protects against the damaging effects of an unhealthy diet, including deficiencies in physical, heart, and metabolic function, equivalent to diabetes.

“We think at both a biological level and a clinical level, poor nutrition choices and inactive lifestyles do accelerate aging,” says Nathan LeBrasseur, Ph.D., director of the Center on Aging’s Healthy and Independent Living Program and senior author of the study. “So now we’ve shown this in very fine detail at a cellular level, and we can see it clinically. And people need to remember that even though you don’t have the diagnosis of diabetes or the diagnosis of cardiovascular disease or the diagnosis of Alzheimer’s disease today when you’re in midlife, the biology underlying those processes is hard at work.”
