Caffeine and Diabetes

Although researchers in Japan are saying those who drink coffee or green tea have reduced risk of diabetes; caffeine remains a concern as a higher risk for diabetes. The Japanese study focused on drinkers of black, green, or oolong tea that were between the ages of 40 and 65.

These researchers are confident that those who drink at least three or more cups of caffeine each day are able to reduce their risk of diabetes by 33 percent. However, other substances in coffee affect the metabolism, and cause other health problems.

Most research shows that avoiding caffeine is the answer to reducing the risks of diabetes. Researchers from a well-known university medical center found a strong tie between caffeine intake at a meal, with increased levels of glucose and insulin among people who have Type 2 diabetes.

Insulin and Caffeine

Insulin is needed by the cells to convert glucose into energy. Having caffeine with a meal hinders the ability to metabolize the meals that are eaten, and should be avoided. Fasting subjects who took part in this research saw no significant change in glucose or insulin levels.

The goal for diabetics is to keep the blood glucose level down. With eating a healthy diet and getting the proper exercise, diabetics should also consider cutting out caffeine.

How does caffeine affect our bodies? Diabetes is the inability to control sugar levels in the blood, either because of the body not producing enough, or having a hormone that resists insulin. Laboratory mice are often fed a chemical called alloxan.


Alloxan is used in the mice to poison the cells that produce insulin and creating the conditions for diabetes. Scientific literature tells us that alloxan is produced in our body from caffeine. Theories are that caffeine produces this toxic substance in our bodies and either causes diabetes, or make existing diabetes worse.

We Americans love our caffeine, and consuming beverages with caffeine is at an all-time high. We may be getting massive doses of alloxan if we drink large amounts of coffee, tea, or sodas that contain caffeine.

Why does alloxan hurt our body? A free radical generator damages our pancreas and can result in pancreatic cancer. A free radical will cause aging, diseases, and especially cancer.

Society and Caffeine

Caffeine is popular with most people today; it gives us the little extra burst of energy we think we need to get through the morning or the day. Some people drink large amounts of caffeine during the day. The cola industry encourages consuming caffeine and some are targeting the younger market.

The 15-21 year old age group is supporting the high caffeine levels by buying products that have abnormally high levels of caffeine. Even a well-known tea company is promoting a high-powered tea with high amounts of caffeine in it. Some juices and bottled waters have caffeine added to them.

Caffeine is a contributor to many diseases including depression, pancreatic cancer, and diabetes. Those that are at a high risk for developing diabetes should avoid caffeine. Caffeine is not only found in coffee, tea, and sodas, but also in chocolate. Even decaffeinated products have a form of caffeine that produces the deadly alloxan.
