Type 2 Diabetes, the most common form of diabetes, has been an increasing global health problem, as pointed out by Joe Vinson, PH.D. Almost 26 million Americans currently battle the disease. Vinson recently led the research on green coffee and its effect on blood sugar levels.
Vinson says on the subject, “A simple natural pill or capsule that would both help control blood sugar and foster weight loss at the same time would be a major advance in the treatment of type 2 diabetes. Our own research and studies published by other scientists suggest that such a treatment may, indeed, exist. There is significant epidemiological and other evidence that coffee consumption reduces the risk of type 2 diabetes. One large study indicated a 50 percent risk reduction for people who drank seven cups of coffee a day compared to those who drank only two cups a day. I am trying to make the coffee and diabetes story as clear as possible for the public. The evidence points to chlorogenic acids as the active ingredients in coffee that both prevent diabetes and improve glucose control in normal, pre-diabetic and diabetic people.
Chlorogenic acids are naturally found in fruits and vegetables like apples, cherries, plums, and others. Due to the popularity of coffee as a beverage, Vinson points out that it is a major dietary provider of these substances as large amounts of chlorogenic substance exist in unroasted green coffee beans. However, roasting breaks down the acids.
Vinson has found in previous studies that obese people who took an extract like that of green coffee lost an average of 10 percent body fat in 22 weeks. This new study’s goal was to document the effects of different doses in commercial green coffee on the blood sugar levels of 56 men and women with normal blood sugar. The patients were given a glucose tolerance test to see how their bodies reacted to sugar, then took 100, 200, 300, or 400 mg’s of the extract in capsule form over time. Their reactions were then documented.
Vinson reports, “There was a significant dose-response effect of the green coffee extract and no apparent gastrointestinal side effects. All doses of green coffee extract produced a significant reduction in blood sugar relative to the original blank glucose challenge. The maximum blood glucose occurred at 30 minutes and was 24 percent lower than the original with the 400 mg of green coffee extract and the blood glucose at 120 minutes was 31 percent lower.”
