20 Best Foods for Kidney Health

SixFruits Editor

Kidney disease is a widespread problem that affects 10% of the world’s population.

Some main risks of kidney disease are diabetes and high blood pressure. However, factors such as gender, age, genetics, smoking, or obesity can increase your risk.

For the reasons mentioned, those who suffer from kidney disease should follow a special diet.

Diet And Kidney Disease

Diet restrictions vary according to the level of kidney damage.  

The diet for people with kidney disease helps improve kidney function and prevent future damage.

It is advisable to restrict the following nutrients:

  • Sodium: less than 2,000 mg daily.

Another nutrient to avoid is protein, as a damaged kidney cannot cleanse its waste.

However, those who suffer from ESRD and are undergoing dialysis have a greater need for protein.

In this article, you will find 20 foods that are kidney-friendly.
