The purpose of a renal diet is to balance the levels of minerals, fluids and electrolytes in the body, as MedlinePlus explains. For this reason, the intake of sodium, phosphorous and potassium should be restricted. Fluid intake should also be restricted to prevent fluid from building up in the body because people with chronic kidney disease and those on dialysis do not urinate very much.
Additionally, MedlinePlus recommends working with a registered dietitian to come up with snack ideas that meet the requirements of a renal diet in addition to a patient's other health needs. However, MedlinePlus also gives some general recommendations for snacking on a renal diet. People who do not have a medical reason to restrict carbohydrates should snack on fruits and breads because they provide fiber as well as vital vitamins and minerals. Those who need to increase their calorie intake can also snack on high-calorie desserts as long as they don't contain dairy, nuts, chocolate or bananas.Learn more about Nutrition & Diets
