Oatmeal has long been a common breakfast food, known for its health benefits. Oatmeal can be great for diabetics as long as the portions are controlled. It’s a healthy energy source, rich in fiber, vitamins, and minerals. A cup of oatmeal a day contains about 30 grams of carbs which can easily fit into a diabetic’s daily diet. Again, use steel cut or rolled whole oats for a healthier variety when choosing your oatmeal.
