Cinnamon and Type 2 Diabetes, Sweet News

2012-06-28 06:30

Reports about the possible benefits of cinnamon for people who have type 2 diabetes have been circulating for years, and not all of them have been positive. A new study from China, however, bears some sweet news and lends support to the research on the positive side of the issue.

What benefit is cinnamon in type 2 diabetes?

A research team from Shanghai Institutes for Biological Sciences, led by Yan Chen, set out to determine if supplements of cinnamon extract could help control blood sugar (glucose) and triglycerides in people with type 2 diabetes. The investigators used a water extract of cinnamon rather than whole or ground cinnamon.

The randomized, double-blind, placebo-controlled study involved 66 individuals with type 2 diabetes who were assigned to one of three groups: placebo, 120 mg of cinnamon supplement daily, or 360 mg daily for three months. All the participants were also taking the antidiabetic drug gliclazide, a sulfonylurea like glipizide and glyburide.

After three months, fasting blood glucose levels were significantly lower in patients who took cinnamon: an average of 1.01 mmol/L in the low-dose group and 1.62 mmol/L in the high-dose group. No change was observed in the placebo group.

Triglyceride levels also were significantly lower in the low-dose group by an average of 0.78 mmol/L, but only slightly lower in the high-dose group.

Based on their findings, the researchers proposed "that cinnamon be considered a promising supplement for the therapy of type 2 diabetes when hyperglycemia cannot be satisfactorily controlled by other strategies such as diet, exercise, and prescribed medication."

They also noted that "the effect of cinnamon on blood glucose control is likely dependent on the form of cinnamon used for the patients," and that the "different extraction methods might affect the efficacy of cinnamon." Some studies, however, have seen good results with other forms of cinnamon.

I have been sprinkling cinnamon onto my morning cereal each day for approximately the last six months. I am a type 2 diabetic. I am age 76. I am otherwise healthy. I have experienced a dramatic reduction in my waist line. My diabetic readings are dramatically improved throughout the day.
That is great news! Thank you for sharing your experience with cinnamon. Have you told your doctor what you are doing? He or she should be interested in your impressive results. Best of health to you!
Deborah, I have an appointment with my physician tomorrow. I intend to explain the great results and suggest he read all the positive information pertaining to consumption of a small amount of cinnamon each day.
George, please let us know what your doctor says when you tell him about your great results.
