Cinnamon May Help Diabetics Lower Blood Pressure
Diabetics often have high blood pressure because diabetes damages the arteries and makes them more susceptible to hardening (also known as atherosclerosis). A recent study – the first of its kind - suggests that taking supplements of cinnamon may help lower blood pressure in people with pre-diabetes and diabetes.
The researchers identified 93 potential studies for their analysis and wound up using three randomized clinical trials. Two of those trials focused on diabetics while the third focused on pre-diabetics.
All three of the studies lasted for 12 weeks, and the dosages of cinnamon used in the studies ranged from 500 mg to 2.4 grams daily. After analyzing all of the data, the researchers found that cinnamon supplementation was associated with a reduction in systolic blood pressure of 5.39 mmHg and a reduction in diastolic blood pressure of 2.6 mmHg.
The researchers caution that the small size of the analysis makes it difficult to definitively determine what element in cinnamon lowers blood pressure in diabetics and that more research is needed.
Researchers from the University of Toronto, the University of West London, and London South Bank University conducted the study. It was published online ahead of print on July 17, 2013, in Nutrition.
Cinnamon is also a great source of manganese, fiber, iron, and calcium. The majority of scientific research on cinnamon has focused on its ability to lower cholesterol and reduce the risk of diabetes. There is, however, also some evidence that it may improve digestion and help treat colds.
