Access : Connecting obesity, aging and diabetes : Nature

Access : Connecting obesity, aging and diabetes : Nature:

"Obesity accelerates the aging of adipose tissue, a process only now beginning to come to light at the molecular level. Experiments in mice suggest that obesity increases the formation of reactive oxygen species in fat cells, shortens telomeres—and ultimately results in activation of the p53 tumor suppressor, inflammation and the promotion of insulin resistance (pages 1082–1087).

Obesity accelerates the aging of adipose tissue, leading to inflammation and insulin resistance.

As technology has improved hygiene, the food supply and living standards overall, there has been a rise in such age-related illnesses as cardiovascular disease, cancer, degenerative diseases of the brain and other organs, and metabolic disorders such as diabetes. Age-related disorders have become widespread throughout the world, replacing infectious diseases as the leading cause of death in developed countries."
