The older people tended to have more activity in several inflammation-related genes compared with the younger group — no surprise, since as people get older, inflammation throughout the body tends to rise. Chronic diseases of aging, like [diabetes](http://time.com/3329225/inflammation-diabetes/), hypertension, [heart problems](http://time.com/4631424/stress-heart-attack-stroke/), cancer, joint disorders and Alzheimer’s, are all believed to have [inflammation](http://time.com/3702053/inflammation-health-effects/) in common. “Most of the diseases of aging are not really diseases of aging, per se, but rather diseases of inflammation,” Furman says. The more active these genes were, the more likely the person was to have high blood pressure and atherosclerosis. What’s more, even among older people, those with lower levels of these factors were more protected against inflammation — and they had something else in common too. They all drank [caffeine](http://time.com/4194950/caffeine-heart-rhythm/) regularly. People who drank more than five cups of coffee a day showed extremely low levels of activity in the inflammatory gene pathway. Caffeine inhibits this circuit and turns the inflammatory pathway off, the researchers say. The goal isn’t to make every trace of inflammation disappear, the scientists stress. In fact, inflammation is an important function of the immune system, which uses it to fight off infections and remove potentially toxic compounds. But with aging, the process isn’t regulated as well as it is in a younger body. “Clearly in aging something is breaking down, and we become less effective at managing this inflammation,” says Mark Davis, director of the Stanford institute. “But now in this paper, we identify a particular pathway that was not associated with inflammation before. We are able to point, with a much higher resolution picture, at aging and the things that should be markers for inflammation.” The key will be to figure out when the inflammatory response starts to spiral out of control. In an upcoming study, Furman and others will soon investigate the immune systems of 1,000 people; he hopes to use that information to develop a reference range of immune-system components to tell people whether their levels are normal, or if they’re at higher risk for developing chronic conditions driven by inflammation. In the meantime, following the example of caffeine-drinking adults with lower levels of inflammation — by having a cup of joe or two — might be a good idea. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/4634553/is-coffee-bad-aging-caffeine/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/4634553/is-coffee-bad-aging-caffeine/"},"headline":"How Your Morning Coffee Might Slow Down Aging","datePublished":"2017-01-16T16:00:14.000Z","dateModified":"2026-02-23T02:43:34.979Z","description":"Researchers zero in on how caffeine appears to fight inflammation","url":"https://time.com/4634553/is-coffee-bad-aging-caffeine/","keywords":["Aging","Cancer","Heart Disease","Caffeine","Coffee","diabetes","Diet & Nutrition","inflammation"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blte5391bed48ad3f0f/698872135f570f2c70b1e715/50-healthiest-foods-coffee.gif?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blte5391bed48ad3f0f/698872135f570f2c70b1e715/50-healthiest-foods-coffee.gif?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"healthiest foods, health food, diet, nutrition, time.com stock, coffee","caption":"healthiest foods, health food, diet, nutrition, time.com stock, coffee","creditText":"Photograph by Danny Kim for TIME; Gif by Marysa Greenawalt for TIME","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/aging/","name":"Aging"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/4634553/is-coffee-bad-aging-caffeine/","name":"How Your Morning Coffee Might Slow Down Aging"}}]}] ```
