Dietary changes may include the restriction of fluid intake, protein , and electrolytes including sodium , phosphorus , and potassium . [ 1 ]
This diet is not the dialysis diet, [56] which is completely different. The healthy kidney diet restricts large amounts of protein, which are hard for the kidney to break down, but especially limits potassium and phosphorus-rich foods and beverages. Liquid intake is often limited as well. [55] [57]

Following the BRAT diet or the bland diet is a form of self-care to ensure you are eating easy-to-digest foods and obtain some nutrients while your body is under GI distress.
The DASH diet (or combination diet) was rich in potassium, magnesium and calcium—a nutrient profile roughly equivalent with the 75th percentile of U.S. consumption. The combination or “DASH” diet was also high in whole grains, poultry, fish, and nuts while being lower in red meat content, sweets, and sugar-containing beverages. [27]
There are some nutrients that are restricted in kidney failure patients because of the body's inability to excrete excessive amounts of them due to the kidneys not functioning properly. In general, these nutrients include: Potassium: The kidneys help to regulate potassium levels. When the kidneys are damaged, potassium levels can become elevated.
Calorie restriction (also known as caloric restriction or energy restriction) is a dietary regimen that reduces the energy intake from foods and beverages without incurring malnutrition. [ 1 ] [ 2 ] The possible effect of calorie restriction on body weight management , longevity , and aging-associated diseases has been an active area of research.
A low sodium diet has a useful effect to reduce blood pressure, both in people with hypertension and in people with normal blood pressure. [7] Taken together, a low salt diet (median of approximately 4.4 g/day – approx 1800 mg sodium) in hypertensive people resulted in a decrease in systolic blood pressure by 4.2 mmHg, and in diastolic blood pressure by 2.1 mmHg.
