When the kidneys fail, they are unable to filter waste from the bloodstream. A kidney disease diet limits the amount of certain nutrients, in order to minimize the amount of waste that must be removed from the bloodstream.

Kidney disease diet:

• Low calorie diet
• Fluid restriction
• Low phosphorus diet
• Low potassium diet
• Low protein diet
• Low sodium diet

Normally, the kidneys help to maintain the levels of calcium and vitamin B in the bloodstream.

Kidney disease diet also includes:

• Vitamin B supplement
• Calcium supplement
