Is Caffeine Really Bad For Type-2 Diabetes? Caffeine is a very interesting item that can be found not only in coffee but also in tea and many soft drinks. Some experts praise it due to its beneficial effects to our body yet others are against it as a result of its harmful effects for us. Researchers at the Duke University Medical Center in Durham, North Carolina found that cutting down on caffeine could actually help people with the most common form of diabetes (Type-2 diabetes) to have better control on their blood sugar levels. Their findings were published on January 28, 2008 in the journal Diabetes Care. Diabetes occurs when a person’s blood glucose levels are too high. Such condition can damage the eyes, kidneys and nerves. Diabetes can also lead to heart disease, stroke and limb amputations. There are 2 types of diabetes and Type-2 diabetes is the form that is closely linked to obesity. In the study, a small group of people with Type-2 diabetes that caused their levels of blood sugar to rise through the day, especially after meals, was given caffeine. They observed that caffeine appears to disrupt glucose metabolism in a way that could be harmful to people with Type-2 diabetes.
This finding seems to be contradicting with the previous research about diabetes and caffeine. Earlier studies indicated that coffee can help people reduced risk of Type-2 diabetes and those who drank more had the lowest risk. One of them can be found in the following page: http://www.howtopreventheartdisease.com/coffee-can-help-diabetes.html Other articles on caffeine are available by clicking HERE. The researchers used new technology, a tiny glucose monitor embedded under the abdominal skin, so that they could monitor the glucose levels continuously in 10 people with an average age of 63. What the researchers discovered is that on days when the participants were given 4 tablets containing caffeine equivalent to 4 cups of coffee, their average daily sugar levels rose 8 percent, compared to days when the same people were given 4 placebo tablets. The results indicated that the coffee consumed by regular coffee drinkers with Type-2 diabetes actually produces an elevation in their glucose throughout the day and the level is above what it should be if they do not consume caffeine. Therefore, they suggested that people with diabetes should avoid coffee and other caffeinated drinks so as to keep their glucose levels low. But why does caffeine raise blood sugar level? The researchers cited 2 possible explanations. Firstly, caffeine may interfere with the process that transports glucose from the blood into muscle and other cells in the body to be burnt as fuel. Secondly, caffeine may also trigger the release of the hormone adrenaline, which can elevate blood sugar levels.
