1 teaspoon of cinnamon provides 6 calories, 2 gm carbohydrate, 1 gm dietary fiber, 3% calcium, and 1% iron. These is insufficient evidence to rate the effectiveness of cinnamon for diabetes. There is inconsistent evidence on the effectiveness of cassia cinnamon for treating diabetes. Early research suggests that taking cassia cinnamon for about 6 six weeks might help control blood sugar in people with type 2 diabetes. However, other evidence suggest that taking cassia cinnamon daily for 12 weeks improves blood pressure, but not cholesterol, blood sugar, or weight in people with diabetes. Overall, research is inconclusive. Some studies show benefit and other studies show no benefit.
You can substitute ½ teaspoon ground cinnamon or 1/8 teaspoon cinnamon extract for 1 cinnamon stick. For milling, wrap the ground cinnamon in cheesecloth or a coffee filter which is tied with a kitchen string or clean twist-tie.
