SN instructed on a low residue diet. A low residue diet is a diet designed to reduce the frequency and volume of stools while prolonging intestinal transit time. It is similar to a low-fiber diet, but typically includes restrictions on foods that increase bowel activity, such as milk, milk products, and prune juice. A low residue diet typically contains less than 7–10 grams of fiber per day. Long term use of this diet, with its emphasis on processed foods and reduced intake of fruits and vegetables, may not provide required amounts of nutrients including potassium, vitamin C, calcium, and folic acid.Patient/caregiver verbalized understanding.
