A renal or kidney diet must be followed by those with impaired kidney function in order to reduce the amount of waste in their blood. Food and liquids we eat and drink contribute to the buildup of waste in our bloodstreams. Renal dysfunction results in an inability to effectively filter and eliminate waste. The electrolyte balance of a patient can be adversely affected by waste remaining in the blood. A kidney diet may also help to maintain kidney function and slow the progression of renal failure.
