A healthy diet plan for renal patients emphasizes the proper intake of potassium, protein and sodium according to the specific recommendations of their doctor, states the Medical College of Wisconsin. As kidney functioning declines, fluid intake may also need to be reduced.
Renal patients may not be able to regulate the removal of fluid from their bodies without fully functioning kidneys, according to the Medical College of Wisconsin. Tips for managing fluid intake include chewing sugarless gum, sucking on ice chips or a lemon wedge and brushing teeth a few times throughout the day. Measuring the allocated amount of fluid allowed in a day and placing it in a designated container helps keep track of how much fluid is consumed.
Renal patients should understand the types of foods that have low and high levels of potassium in order to manage their intake, states the Medical College of Wisconsin. High potassium levels can cause an irregular heartbeat or heart failure. Examples of high-potassium foods include bananas, cantaloupe, broccoli, chocolate and bran products. Low-potassium foods include apples, rice, cucumbers, lettuce and cereal.
It may be necessary to reduce the intake of high-protein foods such as meat, poultry, dairy products and eggs, as well as sodium, including potato chips, nuts, bacon, cold cuts and canned foods, notes the Medical College of Wisconsin. Foods that contain lower amounts of protein include beans, grains and vegetables. Low-sodium alternatives are helpful, including garlic, oregano and other salt-free seasonings.
