Study Finds Link Between Moderate Level Coffee or Caffeine Intake and Risk Of Multiple Cardiometabolic Diseases

Consuming moderate amounts of coffee and caffeine regularly may offer a protective effect against developing multiple cardiometabolic diseases, including type 2 diabetes, coronary heart disease and stroke, according to new research published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Researchers found that regular coffee or caffeine intake, especially at moderate levels, was associated with a lower risk of new-onset cardiometabolic multimorbidity (CM), which refers to the coexistence of at least two cardiometabolic diseases.
“Consuming three cups of coffee, or 200-300 mg caffeine, per day might help to reduce the risk of developing cardiometabolic multimorbidity in individuals without any cardiometabolic disease,” said the study’s lead author Chaofu Ke, M.D., Ph.D., of the Department of Epidemiology and Biostatistics, School of Public Health at Suzhou Medical College of Soochow University, in Suzhou, China.
The study found that compared with non-consumers or consumers of less than 100mg caffeine per day, consumers of moderate amount of coffee (3 drinks per day) or caffeine (200-300 mg per day) had a 48.1% or 40.7% reduced risk for new-onset CM.
Ke and his colleagues based their findings on data from the UK Biobank, a large and detailed longitudinal dietary study with over 500,000 participants aged 37-73 years. The study excluded individuals who had ambiguous information on caffeine intake. The resulting pool of participants included a total of 172,315 individuals who were free of any cardiometabolic diseases at baseline for the analyses of caffeine, and a corresponding 188,091 individuals for the analyses of coffee and tea consumption.
The participants’ cardiometabolic diseases outcomes were identified from self-reported medical conditions, primary care data, linked inpatient hospital data and death registry records linked to the UK Biobank.
Coffee and caffeine intake at all levels were inversely associated with the risk of new-onset CM in participants without cardiometabolic diseases. Those who reported moderate coffee or caffeine intake had the lowest risk, the study found. Moderate coffee or caffeine intake was inversely associated with almost all developmental stages of CM.
“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,” Ke said.
