DISEASE RELATED DIETS: RENAL Pre-End Stage Renal Disease Pages: 487-499 Dialysis Pages: 455-473 DESCRIPTION A diet that is designed to minimize the metabolic complications associated with renal disorders and possibly delay the need for dialysis. The nutrient content of the diet is planned to meet the individual need, usually low protein, sodium and phosphorus. Potassium is not usually restricted unless urine output is diminished or the patients is taking a potassium sparing diuretic. A diet that is used to minimize uremic complications and to maintain acceptable blood chemistries, blood pressure and fluid status while meeting the need of individuals with impaired renal function on maintenance dialysis. The diet is deficient in calcium, iron, Vitamin B12, and zinc due to low phosphorus and protein intake. Diets with 60 grams of protein may be deficient in niacin, riboflavin and thiamin. A specific renal multivitamin (e.g. nephrovite, nephrocaps) is recommended. INDICATIONS PRINCIPLES Patients with pre End Stage Renal Disease or Chronic Renal Insufficiency. FOR ALL RENAL DIETS: Offer high biological value protein sources, such as meat, poultry, fish and eggs within the limits of the protein restriction. * DIABETIC RENAL* GIVE GRAPE JUICE OR APPLE JUICE FOR LOW BLOOD SUGAR Adjust phosphorus allowance for lab values, & reinforce the importance of taking phosphorus binders and limiting dairy products. Supplement dietary calcium intake. Avoid salt and high sodium foods, such as bacon, sausage, luncheon meats, regular soups, and salted snack foods. Do not use salt substitutes that contain potassium, e.g. NuSalt. Avoid high potassium foods like oranges, citrus, prunes, melons, bananas, yams, potatoes, tomatoes, spinach, & winter squash. Limit fluid intake, as instructed. Offer hard candies or chewing gum for thirst. Patients with End-Stage Renal Disease on Dialysis, either Hemodialysis or Peritoneal dialysis. LOW PROTEIN Refer to Liver Disease, pages: 415-419 POTASSIUM RESTRICTED “Low Potassium” Refer to Potassium Modified Diets on Pages: 761-768 SODIUM RESTRICTED Pages: 769-777 A regular diet which provides a specific level of protein according to the individual’s needs. Fluids and electrolytes may need to be restricted due to coincident metabolic complications. Nutritionally adequate at 60 grams of protein; below that is deficient in protein, calcium, folic acid, iron, phosphorus, thiamin, niacin and riboflavin. A regular diet which restricts potassium rich foods in order to achieve and maintain fluid and electrolyte balance when potassium intake exceeds the adaptive abilities of the body. Commonly prescribed levels are 3000mg (77mEq), 2000mg (51mEq), and 1000mg (25mEq)- however less than 2000mg is difficult to achieve through diet, and will limit most vitamins & minerals. A modification of the regular diet that restricts foods high in sodium. This diet is nutritionally adequate and may be ordered at the following levels: 3-4 gram Na (130-174 mEq) = No Added Salt Diet 2 gram Na (87 mEq) Only at MAH & NEBH: 1 gram Na (43 mEq) For treatment of hepatic or other disorders when normal protein levels are not tolerated. Also for lowering serum ammonia levels and to provide essential amino acids. Control amount of protein, choose at least 75% from high biological value sources, such as eggs, meat, fish, poultry and dairy products. Increase calories as necessary by adding high sugar and fat foods as indicated. Indicated in the treatment of hyperkalemia, Renal Failure, massive tissue destruction, catabolic states, adrenal insufficiency, Addison’s Disease. May be required for patients taking potassium-sparing drug therapy and some immuno-suppressive medications. Indicated in the treatment of Congestive Heart Failure, Acute and Chronic Renal Failure, impaired liver function, edema, HTN, CAD, and as an adjuvant to adrenocorticol therapy. Fluid restriction (1000-2000 ml) as needed. Use low protein manufactured products as appropriate. Limit intake of milk and dairy products, fruits and vegetables. Refer to the RENAL DIET list of high potassium foods to avoid. Avoid potassium containing salt substitutes, such as NuSalt and Morton’s Lite. Omit salty foods and added salt, including salt seasonings such as garlic salt. Omit cured foods and restrict processed foods. Refer to the RENAL DIET list of salty foods. CARDIAC DIET Refer to: “Fat and Cholesterol Controlled”, “Step I or II” Pages: 265-288 Refer also to Cardiac Surgery on pages 255-258. DIABETIC diet “ADA”, “Calorie Controlled” Pages: 301-336 A diet that controls overall dietary fat, saturated fat and cholesterol, and based on patient’s nutritional status, management may include sodium, and/or fluid restriction. Other co-morbid conditions (i.e. Diabetes) should be considered when determining appropriate diet therapy. Fluid restriction (1000-2000 ml) as needed. This diet is nutritionally adequate. A regular diet with balanced carbohydrate content designed to guide the person with diabetes in making appropriate food choices and behavioral changes that will result in optimal blood glucose and lipid levels, improved nutritional status and self-management of diabetes. This diet is nutritionally adequate. To lower elevated serum cholesterol levels and other serum lipid levels in the prevention and treatment of hyperlipidemia. For individuals who are at risk for developing heart disease. To control abnormal glucose metabolism due to insulin resistance or the lack of insulin; as seen in Type1 & 2 Diabetes Mellitus, Gestational Diabetes Mellitus (GDM) and Impaired glucose tolerance. 6 ounces or less per day of lean meat, skinless poultry, fish and meat alternatives Skim or 1% lowfat milk Low-fat or fat-free dairy products 6 to 8 teaspoons per day of unsaturated fats and oils Limit egg yolks and regular soups 6 or more servings/day of breads, cereals, rice and pasta; whole grains for more fiber. 3-5 servings per day of vegetables (fresh or frozen) 2-4 servings per day of fruit Limited modified fat desserts Restrict fluids as ordered. Caffeine may be limited. *see FAT RESTRICTED & SODIUM RESTRICTED diet guidelines Provide well-balanced regularly scheduled meals. The diet controls the amount of carbohydrate provided at each meal to ensure adequate, but not excessive portions. Carbohydrates are found in fruits, starches, milk and milk products. Provide appropriate calories for individual needs. Encourage regular exercise. Decrease total fat, saturated fat and cholesterol. Recommend Dietitian Consult for individual Carbohydrate Counting Plan. Timing of meals and medications (such as insulin or an oral hyperglycemic agent) may need to be adjusted based on individual’s treatment plan. NO CONCENTRATED SWEETS Pages: 336A A regular diet with the exclusion of concentrated sources of simple sugars/carbohydrates. The caloric level is not specified but individuals should achieve and maintain their desirable body weight. Non-insulin dependent diabetes, and for patients with medical, psychological or socio-economic circumstances which interfere with compliance to a standard meal pattern. Achieve and maintain a desirable body weight. Avoid concentrated sweets, such as regular desserts, soft drinks, honey, jelly & sugar. Eat well-balanced, regularly scheduled meals. Include high fiber foods. Control portion size. Encourage regular exercise. Decrease total fat, saturated fat and cholesterol. For fasting or post-prandial (reactive) hypoglycemia. Hypoglycemia can occur from impaired glucose tolerance due to delayed and excessive insulin response. Eat small, frequent meals, (usually 6 per day). Meals should be appropriately timed. Meals should be wellbalanced, including complex carbohydrates, protein, fat, and fiber, which help delay absorption of carbohydrate. Limit alcohol and caffeine. Refer to DIABETIC and NO CONCENTRATED SWEETS diets. Not recognized by ADA. REACTIVE HYPOGLYCEMIA Pages: 337-340 (refer to Chapter 20, p.301336, Diabetes Mellitus, for more information to help regulate carbohydrate intake) This diet is nutritionally adequate. This diet minimizes rapid elevation of blood glucose and prevents the symptoms of low blood glucose that may result. Simple or refined carbohydrates should be avoided due to their ability to stimulate rapid insulin secretion. Small, frequent, high-fiber meals should be eaten.
