Coffee Reduces Risk of Diabetes - Decaffeinated Form Cuts Chance of Type-2 By 33 Percent

Coffee Reduces Risk of Diabetes - Decaffeinated Form Cuts Chance of Type-2 By 33 Percent

6 Cups of Coffee Better

Researchers from the University Of Minnesota School Of Public Health say that drinking coffee may reduce the risk of developing type-2 diabetes by up to 33 percent compared to women who don’t drink coffee.  The researchers used 28,812 postmenopausal women who did not have type-2 diabetes or cardiovascular disease as part of the Iowa Women's Health Study (1986-1997) to evaluate the risk.

Over the 11 year period, 1,418 women reported being diagnosed with the disease. The researchers then looked at the coffee intake.  Of the 28,812 women, about half (14,224) drank one to three cups of coffee per day; 2,875 drank more than six cups; 5,554 four to five cups; 3,231 less than one cup; and 2,928 none. 

 

The researchers took into account other risk factors and found that women who drank more than six cups of any type of coffee (caffeinated or decaffeinated) per day were 22 percent less likely than those who drank no coffee to be diagnosed with diabetes. The women who drank more than six cups of decaffeinated coffee per day had a 33 percent reduction in risk compared with those who drank none.

Mark Pereira PhD said “The risk reduction associated with coffee is independent of factors such as weight and physical activity.  There appears to be great potential for coffee to help reduce the risk of diabetes. Identifying the mechanism responsible for this should definitely be the subject of further research." Mark Pereira was the study lead author and associate professor at the University Of Minnesota School Of Public Health.

It is not completely clear what the relationship is, but the researchers say that caffeine intake did not appear to be related to diabetes risk.  This suggests that some other ingredient in coffee was responsible. 

 

The researchers said that “Magnesium, for which coffee is a good source, could explain some of the inverse association between coffee intake and risk of type 2 diabetes mellitus through known beneficial effects on carbohydrate metabolism.”

It is possible that the other minerals and nutrients found in coffee contribute to the protection.  These compounds include polyphenols that have also been shown to help the body process carbohydrates and antioxidants that may protect cells in the insulin-producing pancreas.

Pereira says "Having a healthy diet, controlling your weight, and exercising are essential to preventing the onset of diabetes, but drinking coffee has the potential to further reduce risk of diabetes. It may be necessary to rethink the idea that drinking coffee does more harm than good."

 

High coffee intake has already been associated with lower body mass index (BMI) and rates of hypertension, as well as increased rates of alcohol consumption and smoking. Interestingly, women who drank more coffee also ate less fruit and low-fat dairy products.

Over 20 million Americans have diabetes, with 6.2 million of those cases being undiagnosed. People who have the illness either do not produce enough insulin for the body to process sugar or their cells ignore the insulin that is produced.

The research is published in the June 26, 2006 issue of Archives of Internal Medicine.
