Moderate Coffee Intake Reduces Risk of Diabetes
There is growing evidence on the benefits of drinking moderate amounts of coffee, and among these is its positive influence in the prevention of type 2 diabetes. A recent report, which summarized epidemiological studies suggesting the link between moderate coffee intake and diabetes, was presented at the 2012 World Congress on Prevention of Diabetes and Its Complications. The report highlighted research showing that drinking 3-4 cups of coffee daily may lower the risk for diabetes by 25% compared to drinking none or fewer than two cups daily. Another study showed that there is a dose-dependent relationship between daily consumption of coffee and decreasing risk for diabetes.
While most studies showed an association between coffee drinking and reduction in diabetes risk, none demonstrated a cause-and-effect relationship. However, one clinical trial which evaluated glucose and insulin responses after an oral glucose tolerance test with decaffeinated coffee, chlorogenic acid, trigonelline, or placebo demonstrated that chlorogenic acid and trigonelline contribute to the supposed beneficial effect of coffee by reducing early glucose and insulin responses. This prospective randomized controlled trial provided evidence that major ingredients of coffee (chlorogenic acid and trigonelline) may reduce one’s risk for diabetes by regulating one’s glucose and insulin responses.
The report also pointed out that moderate coffee consumption does not seem to increase the risk of hypertension, stroke, or coronary heart disease, and that patients with cardiovascular disease have a reduced risk of heart failure. However, the authors note that coffee consumption is often linked with some unhealthy habits such as smoking and low levels of physical activity, an effect that may be counter intuitive.
