Learn what types of foods are beneficial for kidney health and what foods to avoid if you’re living with kidney disease. Find out the best fruits, vegetables, proteins, and fluids to consume to improve your kidney function.

According to National Kidney Foundation[1], 10% of the world’s population is affected by kidney disease. Kidneys are incredibly powerful organs that perform many important functions in our bodies. From filtering waste products to releasing hormones that regulate blood pressure and balance bodily fluids and produce urine — it is essential to know what foods help repair kidneys.

When the kidneys aren’t functioning properly, waste products from the food build up in the bloodstream, which is detrimental to your kidneys.

Fortunately, certain nutrient-rich superfoods can help people with kidney ailments maintain a healthy diet while supporting their kidneys.

Diet and Kidney Disease

What foods help repair kidneys depends on the degree of kidney impairment. For instance, individuals in the preliminary phases of kidney illness have different constraints than those with end-stage renal disease (i.e., kidney failure).

Individuals with advanced kidney disease need to stick to a renal diet, which decreases the waste in the blood. This specific diet type helps promote healthy kidneys and prevent additional harm from being done.

While dietary restrictions vary, patients with kidney ailments are recommended to restrict their sodium, potassium, and phosphorus intake. Protein consumption needs to be adjusted as damaged kidneys can’t process the waste products from protein metabolism.

However, end-stage renal disease patients undergoing dialysis require significantly more protein to maintain optimal health. That said, you can find many nutritious and delicious foods low in phosphorus, potassium, and sodium.
