Cinnamon Lowers BP and Improves Insulin Function
6th February 2007 by Arrow Durfee Posted in Uncategorized
SARASOTA, FL, May 1, 2006 – For the first time, cinnamon has been shown to lower the systolic blood pressure (SBP) of spontaneously hypersensitive rats (SHR), according to a new study from Georgetown University in this month’s Journal of the American College of Nutrition. The results also add to a growing body of research demonstrating cinnamon’s role in managing blood sugar levels and improving insulin function. The study found both whole cinnamon and a water-soluble cinnamon extract to be equally effective in managing these conditions.
The placebo-controlled, double-blind study was designed to determine the effect of whole cinnamon, cinnamon extract and chromium, on the SBP and insulin function of SHRs eating a sucrose and non-sucrose containing diet for three to four weeks. Rats taking both forms of cinnamon showed decreased SBP and improved insulin function, with the extract group lowering circulating levels of fructosamine and the whole cinnamon group lowering circulating insulin concentrations.
“Research on cinnamon has pointed to its efficacy in maintaining favorable blood glucose levels and reducing serum cholesterol in people with type 2 diabetes,” said lead researcher Dr. Richard Anderson from the USDA. “This is the first time we have seen the positive effects of cinnamon on blood pressure levels, a common co-factor to diabetes and one of the risk factors associated with cardiovascular disease.”
Spoonful of Cinnamon Helps Treat Diabetes Thu December 11, 2003 04:22 PM ET
by Alison McCook NEW YORK (Reuters Health) – People with diabetes can help keep their bodies healthy by simply adding a dash of spice to their diet, new research reports. In a study, diabetics who incorporated one gram — equivalent to less than one-quarter teaspoon — of cinnamon per day for 40 days into their normal diets experienced a decrease in levels of blood sugar, cholesterol and blood fats. And for people with diabetes, the less of those substances in the body, the better. Type 2 diabetes arises when the body loses sensitivity to insulin, a hormone that shuttles the sugars from food into body cells to be used for energy. As a result, the amount of sugar, or glucose, in the blood remains high, leading to fatigue and blurred vision. Over the long term, excess blood glucose can increase the risk of heart disease, kidney failure and blindness. The current findings suggest that a small amount of cinnamon can help protect diabetics from these and other potential complications of their condition, study author Dr. Richard A. Anderson of the Beltsville Human Nutrition Research Center in Maryland told Reuters Health. Diabetics could add a dash of cinnamon to their morning servings of coffee, orange juice or cereal, Anderson noted. “You can also make a cinnamon tea by simply boiling water with stick cinnamon,” he suggested. Anderson noted that cinnamon may also help stave off the onset of type 2 diabetes in people at risk of the condition. He added that cinnamon contains some substances that can be toxic in high amounts, so people should be sure not to get too much of a good thing. “Certainly, a gram per day is not a high amount,” he reassured. During the study, Anderson and his colleagues asked 60 people with type 2 diabetes to consume 1, 3, or 6 grams of cinnamon each day for 40 days, or the equivalent amount of wheat flour, as a placebo. Both the cinnamon and wheat flour were administered in capsule form. Reporting in the journal Diabetes Care, Anderson and his team found that all cinnamon-takers experienced a drop in blood levels of glucose, fats and cholesterol by up to 30 percent. No change was seen in the people taking placebo capsules. Anderson explained that cinnamon contains compounds that help make insulin more efficient, improving the hormone’s ability to bring glucose to the cells that need it. As an added bonus, cinnamon contains virtually no calories, Anderson said, allowing diabetics to add zest to their meals without adding to their waistlines. Cinnamon contains less than 3 calories per gram, “negligible in the total dietary intake,” Anderson said. Previous research has shown that cinnamon appears to help fat cells recognize and respond to insulin. In test tube and in animal studies, the spice increased glucose metabolism by about 20 times.

OBJECTIVE—The objective of this study was to determine whether cinnamon improves blood glucose, triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol levels in people with type 2 diabetes.
RESEARCH DESIGN AND METHODS—A total of 60 people with type 2 diabetes, 30 men and 30 women aged 52.2 ± 6.32 years, were divided randomly into six groups. Groups 1, 2, and 3 consumed 1, 3, or 6 g of cinnamon daily, respectively, and groups 4, 5, and 6 were given placebo capsules corresponding to the number of capsules consumed for the three levels of cinnamon. The cinnamon was consumed for 40 days followed by a 20-day washout period.
RESULTS—After 40 days, all three levels of cinnamon reduced the mean fasting serum glucose (18–29%), triglyceride (23–30%), LDL cholesterol (7–27%), and total cholesterol (12–26%) levels; no significant changes were noted in the placebo groups. Changes in HDL cholesterol were not significant.
CONCLUSIONS—The results of this study demonstrate that intake of 1, 3, or 6 g of cinnamon per day reduces serum glucose, triglyceride, LDL cholesterol, and total cholesterol in people with type 2 diabetes and suggest that the inclusion of cinnamon in the diet of people with type 2 diabetes will reduce risk factors associated with diabetes and cardiovascular diseases.
