What Is a Renal Diet?

A renal diet consists of limiting one's intake of potassium, fluid, protein, phosphorus and salt. This diet was created for individuals with various stages of kidney disease, in order to limit the progression and symptoms of the disease.

Significance

Kidneys flush toxins in the body, and keep the body's sodium (salt), potassium and fluid balanced. When they are not working properly, any additional salt or fluid could put stress on the kidneys.

Function

The renal diet controls the amounts of sodium, fluid, salt, potassium and protein, so that the correct amounts are consumed to lessen the stress placed on the diseased kidneys.

Time Frame

A renal diet must be followed permanently for those patients who are suffering from kidney disease, even if they receive a kidney transplant.

Considerations

Patients who are following a renal diet must follow a diet that reflects whatever stage of renal failure they are in. Some renal diets may be stricter on limiting the intake of one specific food item over another.

Benefits

Patients who follow strict rental diets will reap the benefits of having good health, while keeping their body strong, and providing proper nutrition.
