Most scientists won’t admit it, but some of them are a lot like journalists. Some people in both groups seem to get their jollies and make their reputations by debunking the work of others.
Cinnamon is now important enough for glucose control that the debunkers have jumped on it. A group of five scientists in Maastricht, The Netherlands, carefully studied the effects of cinnamon and found that it doesn’t work.
They found that “Cinnamon supplementation does not improve glycemic control in postmenopausal type 2 diabetes patients ”. The Journal of Nutrition published their research in its April 2006 issue.
Specifically, they contradicted “ Cinnamon improves glucose and lipids of people with type 2 diabetes ” by Richard A. Anderson and his associates at the Beltsville Human Nutrition Research Center in Maryland and in Peshawar, Pakistan. Earlier I have written about Dr. Anderson’s work on this blog and my website.
The Dutch scientists used the same type of cinnamon, cinnamomum cassia (...
It matters which type of cinnamon you use to help control your diabetes. Some types are more expensive than others. And some types might taste better than others to you, although my taste buds aren’t sensitive enough to tell much difference. But all types of cinnamon can reduce blood glucose levels.
The wave of interest in cinnamon as herbal medicine started half a dozen years ago when U.S. Agriculture Research Service scientists found that its most active compound – methylhydroxy chalcone polymer – increased glucose metabolism 20-fold in a test tube assay of fat cells. The researchers, led by chemist Richard A. Anderson, tested 50 plant extracts and found that none of them came close to this compound’s effect on glucose metabolism.
When the Agriculture Research Service announced its findings, I interviewed Dr. Anderson. At that time he told me that they tried all species of cinnamon and they all worked similarly. “We also tried numerous commercial bottles of cinnamon and they also...
More than 11 years ago I first publicized how cinnamon could help people with type 2 diabetes to control their insulin resistance. Since that time more studies have come out. Some of them indicated that cinnamon might not help, and I wrote here five years ago that I had second thoughts about it. Now, I have third thoughts. A meta-analysis published yesterday shows that cinnamon -- especially cinnamon extract -- produces a modest but statistically signification reduction of fasting blood glucose. The study, “Cinnamon Intake Lowers Fasting Blood Glucose: Meta-Analysis,” appears in the September 2011 issue of the Journal of Medicinal Food , and the abstract is online . The authors are Paul A. Davis of the Department of Nutrition, University of California, Davis, and Wallace Yokoyama of the Western Regional Research Center, U.S. Department of Agriculture. Dr. Davis kindly sent me the full-text of the study on my request. Several of the earlier studies didn’t “discretely...
