One of the spices that lower your blood sugar is cinnamon. To be fair, the research on cinnamon is somewhat inconclusive. Some studies have found positive results while others did not find a significant decrease. However, cinnamon does have lots of vital nutrients that can decrease inflammation which in turn can increase blood flow.
Plus, cinnamon can help promote weight loss, lower bad cholesterol, and speed up your metabolism. You can put cinnamon on your oatmeal and you will get a double benefit, as oatmeal is a food item that helps you manage your diabetes.
