A new study suggests that moderate consumption of coffee and caffeine may have a beneficial effect on cardiometabolic health, helping to prevent diseases such as type 2 diabetes, coronary heart disease, and stroke. People who drank 3 coffee drinks per day or 200 to 300 milligrams of caffeine a day had a reduced risk for new-onset cardiometabolic multimorbidity. However, it is important to note that there is no proven causal relationship between caffeine consumption and the prevention of cardiometabolic diseases.
The UK Biobank study data used in the research included various sources such as inpatient hospital data, death registry records, primary care history, and self-reported medical conditions. After analyzing the data, the researchers found that those who consumed moderate amounts of coffee and caffeine had a lower risk for new-onset cardiometabolic diseases compared to those who consumed little to no caffeine. This association could have a significant impact on preventing cardiometabolic multimorbidity, which is the co-occurrence of cardiometabolic diseases.
While other studies have examined the potential benefits of coffee, tea, and caffeine, the role of these beverages in preventing cardiometabolic diseases has not been definitively established. This study’s results suggest an association rather than a causal relationship. However, given the increased mortality risk associated with cardiometabolic diseases, the findings highlight the potential benefits of promoting moderate coffee or caffeine intake as part of a healthy diet to prevent cardiometabolic multimorbidity.
Caffeine is associated with adverse effects such as insomnia, depression, and stomach problems. People with type 2 diabetes may experience an increase in blood sugar levels after consuming caffeine, as it may impair insulin action. The Food and Drug Administration recommends limiting caffeine intake to 400 mg per day for healthy adults, which is roughly equivalent to 4 to 5 cups of coffee.
Experts note that the beneficial properties of coffee and tea extend beyond caffeine, as these beverages contain numerous bioactive compounds with antioxidant and anti-inflammatory effects. The protective benefits of moderate caffeine intake seen in the study may be attributed to these compounds in addition to caffeine itself. However, it is important to note that not all caffeinated beverages provide the same benefits, and certain populations, such as individuals with high blood pressure or anxiety disorders, should limit caffeine consumption.
Overall, the study suggests that moderate coffee and caffeine consumption may have protective benefits for the cardiometabolic system, potentially reducing the risk of cardiometabolic diseases. However, individuals should be mindful of their overall caffeine intake and consider the potential risks associated with excessive consumption. Choosing coffee over other caffeinated beverages and limiting added sugar and cream can be a healthier option based on the study’s findings.
