Renal failure is the rapid deterioration of kidney function, resulting in the accumulation of nitrogenous waste products of protein metabolism.
There is a sudden shutdown of renal function following metabolic insult or traumatic injury to normal kidneys.
The urine output may be as little as 20-200 mL/day.
Serum urea nitrogen and creatinine levels are increased.
Principles of Renal Failure Diet
A high-calorie, low-protein, moderate-fat, restricted sodium and potassium diet is prescribed.
- When vomiting and diarrhoea are seen, avoid oral intake of food; instead, intravenous glucose should be administered.
- Fruits and vegetables should be leached and given as they contain potassium.
- Sodium is restricted in the diet, so salt should be restricted as much as possible.
- Coconut water should be avoided as it contains high amounts of potassium.
Foods to be included for the Renal Failure Diet
Rice, idlis, sago, upma, barley water, ragi malt, porridges, rasam, gruels, and soft foods;
Vegetables like bottle gourd, potato, ridge gourd, and salads can be included.
Fruits and vegetables should be leached and given.
Foods to be avoided for a Renal Failure Diet
Protein foods should be avoided, like pulses, beans, peas, eggs, milk, meat, fish, table salt, unleached fruits, and vegetables.
Potassium-containing foods like leafy vegetables like spinach, broccoli, and tomatoes; coconut water; bananas; watermelon; avocados; and grape juice.
If the person is undergoing dialysis, high biological value proteins should be provided, like eggs, milk, chicken, fish, etc.
