Coffee can lower risk type 2 diabetes mellitus

Several large prospective studies have reported an inverse association between coffee consumption and risk of type 2 diabetes mellitus. High coffee consumption has been associated with better glucose tolerance and substantially lower risk of type 2 diabetes mellitus in diverse populations in Europe, U.S., and Japan. The inverse associations between coffee intake and diabetes risk were stronger for decaffeinated coffee than for regular (caffeinated) coffee.

The major diterpenes in coffee are cafestol and kahweol, which make up approximately 1% (wt:wt) of coffee beans. Both cafestol and kahweol increase insulin secretion and glucose uptake in muscle cells.

Cafestol is universally present in Coffea species. Researchers have found that cafestol – a bioactive compound present in coffee – increased insulin secretion, reduced fasting glucose levels, and improved insulin sensitivity in mice.

Previous studies have shown that moderate coffee consumption may prevent the development of type 2 diabetes mellitus and confirmed that caffeic acid and chlorogenic acid have the potential to decrease the risk of type 2 diabetes mellitus.

The differentiation between filtered and boiled coffee may be relevant for risk of type 2 diabetes mellitus. It was observed that for the same amount of coffee, risk was lower for people who consumed filtered coffee.

Health benefit of coffee: antidiabetes

A significant reduced risk of diabetes among coffee drinkers is consistent with many studies. It was concluded that habitual coffee consumption is associated with a substantially lower risk of Type 2 diabetes (Van Dam, and Hu, 2005).

Harvard investigators followed more than 126, 000 subjects for up to 18 years and found that men who drank more than six cups (48 ounces) of coffee daily reduce they diabetes risk by more than 50% (30% for women). The effect faded with fewer than three cups per day.

Salazar-Martinez and colleagues’ study suggests that long-term coffee consumption is associated with a significantly lower risk for type 2 diabetes mellitus.

In the Pizarra study, a crosssectional study of 1226 randomly selected adults from a small town in Spain, persons who drank coffee at least once per day had a lower risk for diabetes mellitus and impaired glucose tolerance (odds ratio, 0.66 [95% CI, 0.48 to 0.92]; P 0.02) than persons who drank coffee only occasionally, after adjustment for age, sex, obesity, and smoking.

Coffee, caffeine and diabetes

Caffeine can be found in tea, some soft drinks, chocolate, coca and many other the counter medicines. Coffee is the main contributor to caffeine consumption.

Coffee is a complex mixture of chemicals that provide significant amounts of chlorogenic acid and caffeine. In research findings published in mid 2004 in Diabetes Care, researchers at the Duke University Medical Centre in North Carolina found that caffeine interferes with blood sugar controlled, they found strong correlation between caffeine intake at mealtime and increased glucose and insulin levels among people with type 2 diabetes.

Many other studies have shown that excessive caffeine raises blood sugar. Caffeine inhibits glucose metabolism and thereby raise blood sugar levels which is dangerous for people with diabetes.

According to 2008 study published in Diabetes Care, the participant wearing a glucose monitor for seventy two hours revealed that when participants drank coffee (two cups of coffee daily), their blood sugar elevated by 8 percent.

Caffeine consumption also exaggerated the rise in their blood sugar after meals: by 9% after breakfast, 15% after lunch and 26% after dinner.

The findings are significant enough that the researchers recommend that people with diabetes consider reducing or eliminating caffeine from their diets.

Coffee consumption reduced the risk of diabetes

According to a study from the University of California at San Diego coffee drinkers are less to develop pre-diabetes and type 2 diabetes than those who don’t sip.

Drinking as little as one cup of coffee daily reduced the risk of type 2 diabetes by 60 percent compared to people who never drink coffee.

Published in the November 2006 issue of Diabetes Care, the study revealed that coffee offered protection at the same, significant levels for those beginning the study with high fasting glucose levels, indicating pre-existing glucose intolerance, as it did for those with normal levels.

In fact, those with elevated glucose levels showed a lower risk of developing diabetes than those starting out with normal glucose tolerance.

In another study by University of Minnesota in 1997, the experts suspected that compounds and mineral in coffee beans may improve the sensitivity of insulin receptors and help the body process bloods sugar more efficiently.

Please note that these studies pertain to preventing diabetes. Unfortunately most people consume their coffee loaded with sugar and cream that are likely to raise blood sugar as well.

Uncovering the first evidence that coffee also reduces diabetes risk among pre-diabetics, the risk level came in even lower, at 0.31, for the subgroup with impaired glucose. That means pre-diabetics reduced their risk of developing the disease by almost 70%.

Diabetes is the fifth leading cause of death by disease in the United States. Diabetics are also at higher risk for heart disease, blindness, kidney failure, extremity amputations and other chronic conditions.

For diabetics 
However there’s a caffeine caution: caffeinated beverages can spike blood sugar for thirty minutes after consuming them, so some experts suggest to switching to decaf coffee if you have diabetes, of drinking tea which has considerably less caffeine than coffee.

In research findings published in mid 2004 in Diabetes Care researchers at the Duke University Medical Center in North Carolina found that caffeine interferes with the blood sugar control; they found a strong correlation between caffeine intake at mealtime and increased glucose and insulin levels among people with type 2 diabetes.
