Moderate coffee consumption may help reduce the risk of developing diabetes and cardiovascular diseases, according to a recent study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism. The study found that individuals who consume between 200 to 300 mg of caffeine per day, equivalent to about 2-3 cups of coffee, have a 40% lower risk of developing cardiovascular diseases and type 2 diabetes compared to those who consume little or no caffeine daily.

Experts confirm that coffee and tea contain numerous beneficial bioactive compounds, such as flavonoids and polyphenols, which have antioxidant and anti-inflammatory effects, supporting glucose and lipid metabolism in the body. These compounds may provide long-term health benefits that are not solely attributed to caffeine. However, it is crucial that consumption remains moderate, as excessive coffee intake can lead to unwanted side effects such as insomnia or anxiety.
“The findings from this study suggest that moderate coffee consumption can bring significant benefits in preventing cardiovascular diseases and type 2 diabetes,” according to Dr. Chaofu Ke, the lead author of the study from the School of Public Health at Suzhou University, China.
Previous studies have examined the effects of caffeine and coffee on cardiovascular health, but the results have not clearly established a relationship between coffee consumption and a reduced risk of cardiovascular and metabolic diseases. However, this study, based on data from over 360,000 participants using information from the UK Biobank, showed that moderate coffee drinkers reduced their risk of developing multiple cardiovascular diseases by 48.1%.
One important point that researchers emphasize is that coffee is not the only method for preventing these diseases. Other caffeinated beverages, such as sodas or energy drinks, do not provide the same health benefits due to their high sugar content. Therefore, opting for black coffee without sugar could be a better alternative to sugary drinks or those with additives.

The study also warns that, while coffee may have health-protective benefits, for some individuals, especially those with difficult-to-control cardiovascular diseases, hypertension, anxiety, or digestive issues, consuming too much caffeine may not be suitable. Therefore, people should adjust their coffee consumption to match their individual health needs.
“Adopting the habit of moderate coffee consumption can be a simple but long-lasting step in reducing the risk of diabetes and cardiovascular diseases.” However, an overall healthy lifestyle, including a balanced diet, regular exercise, and stress management, remains the most important factor in maintaining health.
