Caffeine and Diabetes

By Phillip Blunzon | June 11, 2007

Diabetes is a disease that has long plagued patients around the world; yet despite the history and prevalence of the condition, it continues to mystify doctors, researchers and patients. One mystery is the correlation between diabetes and caffeine.

Researchers in Japan have claimed that people who drink coffee or green tea can reduce their risk of diabetes. On the other hand, medical experts also claim that caffeine poses a higher risk for diabetes. A study was conducted on people between the ages of 40 and 65 who drank green, black or oolong tea. These researchers found that, based on the study, those who drank at least three or more cups of caffeine each day were able to reduce their risk of diabetes by 33 percent. However, other substances in coffee can have a negative effect on metabolism, causing other health problems.

Most modern research shows that avoiding caffeine is still advisable for those wanting to reduce the risk of diabetes. Researchers from a well-known university medical center found that drinking caffeine with meals caused an increase in glucose levels and insulin among people suffering Type 2 diabetes. Insulin is a component required for cells to convert glucose into energy. When a person with diabetes drinks caffeine with a meal, the caffeine can hinder the ability to metabolize the meals that are eaten. Fasting subjects who took part in this research saw no significant change in their glucose or insulin levels.

Diabetes patients know that it’s important to lower blood glucose levels. Healthy levels can easily be maintained by eating the right foods and exercising regularly. Now, these new medical findings suggest that reducing or eliminating caffeine is another way to control diabetes.

When a patient suffers from diabetes, his or her body does not have the ability to control sugar levels in the blood. Many patients are also faced with the body’s inability to produce sufficient insulin. Others have a hormone that resists insulin. All of these patients must be concerned with the amount of tea and coffee they ingest, as caffeine has been shown to have a direct negative effect on insulin levels.

A chemical called alloxan is a known cause of diabetes. This theory was proven in lab tests where mice fed with alloxan developed diabetes. Alloxan is a free radical generator that not only poisons our insulin-creating cells, but can also cause aging and disease. Alloxan causes damage to the pancreas, including pancreatic cancer. Caffeine causes the natural creation of alloxan in the body, therefore increasing the chance of developing diabetes, or making an existing condition worse.

Even though the consumption of caffeine can contribute to many health concerns and diseases, people around the world continue to thrive on it. Caffeine is present in tea, coffee, soft drinks, chocolate and many diet and energy supplements. People who drink several cups of coffee, tea or soft drinks on a daily basis are taking in massive doses of harmful alloxan. Even decaffeinated beverages contain some caffeine and, therefore, certain levels of alloxan. Everyone should limit their caffeine intakes, particularly those at risk of, or suffering from, diabetes.

Caffeine intake used to be a health issue reserved for older patients. Now, younger people are facing the same dangers. The soft drink industry is, sadly, marketing “power drinks” with dangerously high levels of caffeine to consumers in the age 15-21 demographic. Some juices and even bottled waters are infused with caffeine, and even respected tea manufacturers are producing “high-powered” teas that are packed with caffeine.

If you are interested in preventing the onset of diabetes, consider lowering your caffeine intake. If you already suffer with the disease, speak with your doctor about the correlation between caffeine and diabetes. For your good health, take steps to reduce caffeine. For optimal health, eliminate it from your diet altogether.
