Kidney disease is a common problem affecting about 10% of the world’s population. The kidneys are small but powerful bean-shaped organs that perform many important functions. When the kidneys aren’t working properly, waste builds up in the blood, including waste products from food. Therefore, it’s necessary for people with kidney disease to follow a special diet. Dietary restrictions vary depending on the level of kidney damage. We will determine the best diet for your individual needs. For most people with advanced kidney disease, it’s important to follow a kidney-friendly diet that helps decrease the amount of waste in the blood. This diet is often referred to as a renal diet.
