For centuries, spices have proven to be powerful tools when it comes to helping control diabetes. Cinnamon and turmeric are spices that can be easily added to your diet, whether consumed with food or as a tea. Not only do they add flavor to your food, they can lower blood sugar levels which helps improve insulin sensitivity while reducing hemoglobin A1c levels. They can also help reduce the risk of developing heart disease, while benefiting kidney health at the same time.
