There may be a touch of ancient wisdom at work in all the recipes which combine cinnamon with high-carb and high-fat ingredients. Cinnamon can mitigate the impact these foods have on blood sugar levels, slowing the rate at which the stomach empties after meals and thereby reducing the potential spike in blood sugar. Cinnamon can offer aid to people who have type 2 diabetes by preventing insulin resistance and has even been recommended by the American Diabetes Association. Research has shown cinnamon outperforms diabetes drugs. In a study published in The Journal of Diabetic Medicine, research subjects given cinnamon supplements experienced greater improvement in blood sugar levels than those who received standard diabetes drugs.
Cinnamon has the ability to inhibit the growth of harmful bacteria, molds and yeasts, including Candida yeast. In a 2003 study, two batches of vegetable broth were refrigerated, one with, and one without cinnamon oil. The broth with the cinnamon oil was resistant to food-borne pathogenic Bacillus cereus for at least 60 days. Researchers in this study observed that the cinnamon not only served as an effective preservative but also improved the flavor of the broth. In another study, researchers at Kansas State University discovered that cinnamon eliminates E. coli in unpasteurized apple cider.
