A nutritionally balanced diet is the best diet to prepare yourself for surgery. This means 5-9 servings of fruits and vegetables, preferably lots of different colors, good sources of protein from fish, meats, beans, eggs, soy or dairy, whole grain breads and cereals and limited empty calorie foods. If you are eating a balanced diet there is no need for a multiple vitamin although it is not contraindicated. Keeping the body in good physical condition through exercise and diet before surgery will make the recovery faster and easier.
