Cinnamon

Not many people would suspect cinnamon of having a slew of medical benefits, but it actually does. The American Journal of Clinical Nutrition found that a teaspoon of cinnamon added to a largely starchy meal, like oats, can help combat insulin spikes and stabilize blood glucose levels. The antioxidants in cinnamon, called polyphenols, have been proven to improve your body’s ability to store fat and manage hunger by way of improving insulin sensitivity.
