subject: Diabetic Meal Plan for a Diabetic [print this page] Fibre diet is highly recommended for the diabetic meal plan. Keep in mind that fibre is slowly digested by the body. This means that it will help to fill your stomach without raising the blood sugar of your body. Oranges, potatoes, beans and oatmeal are good recommendations for this kind of food. Also drink a lot of water. This will help to keep the body hydrated and prevent kidney harm.
