ATLANTA (CBS Atlanta) – Numerous studies have, in the past, warned people of the negative effects of drinking caffeinated beverages such as coffee.

The Partnership At describes caffeine as a psychoactive stimulant on their website, citing the Centers for Disease Control and Prevention in Atlanta and the National Institute on Drug Abuse as sources of information on the matter.

“Caffeine is addictive,” the site notes. “Tolerance and dependence may develop after prolonged caffeine use. This reduces the chemical compound’s perceived stimulant effects.”

But while excessive consumption of caffeine comes with some negative consequences, drinking coffee may have at least one positive effect – preventing a rare autoimmune disease that affects the liver.

A new study, run by researchers at the Mayo Clinic in Rochester, Minn., examined three groups of patients, Medical News Today is reporting. One group was healthy, while one had primary sclerosing cholangitis and a third had a similar disease called primary biliary cirrhosis.

The team reportedly found that most PSC patients had never consumed coffee, or did so at rates that paled in comparison to the healthy group. Coffee did not, however, have a preventative effect for PBC patients.

Craig Lammert, a gastroenterologist and hepatologist at the Clinic who was involved with the study, will be presenting the findings of the study the annual Digestive Disease Week conference, the website learned.

He additionally described the study as “a novel environmental factor that also might help us to determine the cause of this and other devastating autoimmune diseases.”
