NEW YORK (CBSNewYork) -- If you drink a lot of coffee a new study may kill your caffeine buzz.
Men and women who drank 28 cups of coffee a week had a 21-percent higher death rate than non-coffee drinkers. Those younger than 55 had more than a 55-percent increased risk of death, according to the study published in the Mayo Clinic Proceedings.
Study: Too Much Coffee Could Increase Your Risk Of Death
The study followed more than 40,000 men and women. For the purposes of the study a single cup of coffee was considered 8 ounces.
Coffee drinkers told CBS 2's Cindy Hsu on Thrusday that they weren't surprised by the results.
"Everything in moderation. Too much caffeine, too much this, too much that, you get in trouble," Gary Drake said.
Medical experts explained that the results of the study should cause panic and that negative health consequences could be avoided by limiting intake to two small cups of coffee per day.
"We don't know whether they had other bad health habits, how strong their coffee was, did they put a lot of high-fat cream into their coffee as well," Saint Luke's and Roosevelt Hospitals' Dr. Merle Myerson said.
Some drinkers said they had already started to cut back.
"It's not too bad. I still drink some tea. So, I get the caffeine that way," Shana Goldstein said.
Others said that the results of the study were enough to make them change their habits.
"I don't see a problem with disciplining myself, cutting down on coffee. Actually, I'm going to start today," Nick Parra said.
Everybody responds to caffeine differently, experts said. Concerned coffee drinkers are advised to speak with a doctor.
