One of the more interesting but less often discussed applications for cinnamon is in health enhancement for pre-diabetic men and women, persons who may have "borderline" high blood sugar levels, cholesterol, and triglycerides, along with high blood pressure and bulging waistlines.
A study of cinnamon for prediabetic men and women conducted in northeastern found that taking the commercial product Cinnulin PF for two weeks:
- Reduced blood pressure (systolic) about 5 mm Hg,
- Reduced blood sugar levels about 10 mg/dl,
- Increased lean body mass about 1%, and
- Decreased fat mass about 0.7%.
The recommended daily dosage of two capsules of the Cinnulin PF product is claimed to be the equivalent of about 10 grams of powdered cinnamon. It concentrates the polyphenols believed to be most active in blood sugar regulation.
The test ran for a very short time, and got very small, but statistically significant results (which is hard to do when you only have 22 volunteers for your trial). The test did not find changes in triglycerides or cholesterol, but this can be explained by the fact that volunteers in the study did not have high triglycerides or high cholesterol. The changes in blood sugar levels, while beneficial, were not substantial enough to affect fats in the bloodstream (which didn't need treatment, anyway).
This is a preliminary study, but anything that helps prediabetics lose weight seems worth a second look.
