Coffee can jump start your morning, but it may have adverse effects on your kidneys.

In a recent study published in the Clinical Journal of the American Society of Nephrology, researchers from Johns Hopkins found that select metabolites associated with coffee could negatively affect kidney health and contribute to chronic kidney disease.

Chronic kidney disease is found in one in seven adults in the United States with the majority of them over the age of 65, according to the Centers for Disease Control.

The study, which examined metabolites 372 metabolites in more than 4,000 people with an average age of 48 years, found a metabolite that can help kidney health, but two that can contribute to CKD. A metabolite, according to the National Cancer Institute, is a substance created during the process of metabolism.

Previous studies have suggested that metabolites in coffee could lead to better kidney health, but the findings in the study suggest that, while there is a metabolite that can help the kidneys, there is a higher health risk than previously thought.
