More evidence suggests that cinnamon may reduce risk factors associated with diabetes

Last year I wrote a post about cinnamon and how it can impact blood sugar balance.  A recent study (1) suggests that a water soluble cinnamon extract, with antioxidant capacity, might be useful in reducing certain risk factors associated with type 2 diabetes and heart disease.

The study (1) lasted 12 weeks and involved 22 obese individuals with a condition often known as ‘prediabetes’ where blood glucose levels are impaired.  Prediabetes occurs when cells are resistant to the higher-than-normal levels of insulin produced by the pancreas (in an attempt to help remove elevated glucose levels from blood).  Individuals were given either an inactive placebo or 250mg of a dried water-soluble cinnamon extract twice a day.  Their diets were not changed.  Blood was sampled after an overnight fast at the beginning of the study, after six weeks, and after 12 weeks to measure the changes in blood glucose and antioxidants (1,2).

Results showed that the cinnamon extract improved antioxidant status in the individuals taking it and that this improved antioxidant status was correlated with a reduction in fasting glucose levels (1).  Although the results are interesting further research is needed before cinnamon can be recommended as a way to control blood glucose levels.  Until larger trials are conducted the main factor in preventing type 2 diabetes in overweight and obese individuals is achieving weight loss. 

A review paper (3) written about cinnamon mentions the fact that human studies involving subjects with metabolic syndrome, type 2 diabetes mellitus, and polycystic ovary syndrome all show beneficial effects of whole cinnamon and/or aqueous extracts of cinnamon on glucose, insulin, insulin sensitivity, lipids [fats], antioxidant status, blood pressure, lean body mass, and gastric emptying.  The authors of this paper stress the fact that the type and amount of cinnamon that is most useful needs further investigation.

As mentioned in my previous post Cinnamon appears to work by helping the body with the way it deals with sugar in the blood via various mechanisms.  Cinnamon supplements are available (but always check with your medical doctor prior to taking any supplements) and you can use cinnamon as a natural sweetener on morning oats/porridge and in baking and cooking.  However, the best way to balance blood sugar levels is to eat a healthy, nutritious diet with a low glycaemic load.  Eating a healthy, balanced diet will help to prevent blood glucose imbalance in the body.  A diet that is high in minimally process foods, vegetables, fruits, unrefined whole grains, beans/pulses, nuts/seeds, lean protein, oily fish (such as salmon, mackerel, sardines and trout) will go far in reducing the post-meal increases in glucose, triglycerides (blood fats) and other markers of disease compared to a typical western diet that is processed and full of high GI carbohydrates.
