High blood sugar isn’t healthy for anyone, particularly people dealing with or predisposed to diabetes. One all-natural way to keep blood sugar in check is by consuming cinnamon. This tasty spice has been shown to reduce oxidative stress, which damages cells and can affect blood sugar. Packed with antioxidants, cinnamon is healthful and heart-healthy. Swirl some into your oats, sprinkle onto yogurt, or even use in savory dishes.
