A new study by the Stanford University School of Medicine has found that caffeine may help address a chronic inflammatory problem in older people that can lead to cardiovascular problems.
“More than 90 percent of all noncommunicable diseases of aging are associated with chronic inflammation.” Furman added that inflammation can contribute to many cancer, Alzheimer’s and dementia, heart disease, and even depression. Furman is a consulting associate professor at the Stanford Institute for Immunity, Transplantation and Infection. Chronic inflammation is caused by
metabolites in the blood; according to researchers, caffeine and its metabolites may help counter the effects of inflammation-causing metabolites.
Researchers noted that this may be a reason why people who drink coffee tend to live longer on average than those who don’t. “It’s also well-known that caffeine intake is associated with longevity,” Furman said. “Many studies have shown this association. We’ve found a possible reason for why this may be so.”
Mark Davis, PhD, a professor of microbiology and immunology and the director of the Stanford Institute for Immunity, Transplantation and Infection, and a senior author of the study, said, “What we’ve shown is a correlation between caffeine consumption and longevity.” Davis did point out that the findings don’t necessarily indicate a causal link.
In June 2016, the World Health Organization announced that it no longer considers coffee a carcinogen, reversing a 25-year position on the subject.
