Having more than four cups of coffee a day is linked to a higher mortality rate for people under 55 years of age according to the New York Daily News.
"We're not saying that coffee is the cause of death; we just noticed coffee is associated with increased risk of death," New Orlean's Ochsner Medical Center Department of Cardiovascular Diseases Director Carl Lavie told the Daily News.
Lavie said consuming less than four cups didn't show any positive or negative health effects.
"The low doses seem to be very safe," he said. "And that's still a fair amount of coffee.
"I do think it would be reasonable to use some caution at doses of four cups a day and above, and realize that a cup is probably a 6- to 8-oz. cup and not the grandes and supergrandes that are now available. It appears to be safe in small to moderate amounts, and there may even be some benefits," he said.
The study also found that those under 55 years of age who consumed 28 cups of the beverage a week, or about four per day, were associated to a 21 percent higher mortality or death rate in men and women of all ages the Daily News reported.
A study of 40,000 people in the Mayo Clinic Proceedings Journal found people under 55 years old had a 50 percent higher rate for death.
The findings are based off data analysis from an Aerobics Center Longitudinal Study cohort that tracked a group of men and women who were over the age of 16 between were between 20 to 87 years old and asked to provide an estimate about how much coffee they consumed each week the Daily News reported.
According to the study, those who consumed the beverage heavily had a greater possibility of dying from any cause than those who had the beverage in a moderate amount or not at all.
