Coffee Consumption Proves Potential in Reducing Type 2 Diabetes Risk

Aug 7, 2015

Coffee may play a role in decreasing inflammation and thus have an association with lower diabetes incidences…

A recent study sought to investigate any associations between coffee drinking, diabetes development and measured inflammatory and oxidative biomarkers.

Scientists have suggested there is an inflammatory process involved in the development of type 2 diabetes by showing an increase in serum amyloid in type 2 diabetes patients. Moreover, other studies have suggested coffee may improve cognitive function and decrease heart disease–disorders associated with inflammation.

In this observational study, 3,042 total patients were given questionnaires to assess their coffee drinking habits, as well as, lifestyle and dietary factors. Diabetes incidence was documented. Inflammation and oxidative stress was also evaluated. Patients were placed into three groups based on coffee consumption: abstinent, casual or habitual coffee drinkers.

Ten years from the beginning of the study, 191 patients had developed type 2 diabetes. With adjustments, individuals who consumed 1.5 cups of coffee per day (habitual drinkers) had 54% lower odds of developing diabetes when compared to abstainers.

Interestingly, those with higher coffee consumption tended to have lower serum amyloid levels in the study. While this observational study cannot pinpoint cause and effect, we can see a potential association between coffee drinking, lower diabetes risk and lower inflammation.

Clearly, this study does not replace the well-known fact that exercise and diet remain the key most important factors in diabetes prevention. Nonetheless, the positive findings of coffee consumption and reduced diabetes risk is promising.

Practice Pearls:

  • Coffee drinking has been shown to play a role in reducing inflammation, which may prove important in managing chronic conditions.
  • Drinking 1.5 cups of coffee per day showed great odds reductions in the development of type 2 diabetes.
  • This observational study brings light to promising information, but does not replace the importance of diet and exercise in the prevention of type 2 diabetes.
