People with diabetes often face dietary restrictions to control their blood sugar and prevent complications. Limited research suggests that cinnamon might help improve blood sugar control in those with diabetes.Although research is at a preliminary stage, cinnamon may help counter some effects of diabetes. While other studies question these effects, cinnamon is unlikely to cause blood pressure spikes or disrupt blood sugar.The National Center for Complementary and Integrative Health (NCCIH) has confirmed that cinnamon does not effectively treat any health problem.However, even if the suggested benefits of cinnamon require further confirmation, it is a safe, flavorsome way to replace sugar in the diet
