People who drink three cups of coffee a day have less chance of developing simultaneous heart and metabolic conditions, according to a new study published Tuesday in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

The study categorized drinking three cups a day as moderate and found that people who did so were 48.1% less likely to have an onset of cardiometabolic comorbidity, which means the coexistence of two such conditions, compared with people who didn’t drink coffee or don’t intake too much.

Most adults can have about 400 milligrams of caffeine a day safely, equivalent to “two to three 12-fluid-ounce cups of coffee,” the Food and Drug Administration says on its website.

The study used data from Britons ages 37-73, 188,091 for tea and coffee analysis and 172,315 for caffeine analysis. The cardiometabolic diseases used for the study were type 2 diabetes, coronary heart disease and stroke.

“The findings highlight that promoting moderate amounts of coffee or caffeine intake as a dietary habit to healthy people might have far-reaching benefits for the prevention of CM,” lead author Chaofu Ke of Soochow University in Suzhou, China, said.
