Renal diet 101 – everything you need to know about how to follow a renal diet

If you have renal disease, your kidneys are not able to work as they should. This means they cannot filter your blood properly and remove waste from your body efficiently. As a result, following a renal diet is crucial to help manage your condition and protect your kidney health.

What is a Renal Diet?

A renal diet is a specialized eating plan designed for people with kidney disease. Its primary goal is to help protect the kidneys from further damage and improve their function. This diet typically includes foods that are low in sodium, potassium, and phosphorus while being high in protein. Fluid intake is also often restricted to prevent excess strain on the kidneys.
