Suffering from Kidney Disease? Know Your Diet

  • Kidneys are the body organs that perform many important functions, including blood filtration, blood pressure regulation, electrolyte balancing, and urine production. However, some health disorders, such as high blood pressure, diabetes, and obesity, as well as your lifestyle and nutrition, can harm your kidneys, limiting their ability to function.

However, for people with kidney disease, also known as renal disease, eating a balanced diet means making sacrifices, such as giving up a favorite dish or drink and many other foods, including healthy ones.

However, people with kidney disease may need to limit their intake of certain fruits mainly those high in sugar and potassium, such as bananas, avocados, apricots, kiwi, and oranges. These fruits are not recommended for people who have kidney disease.
  • Dried fruits:

  • Dried fruits are prepared by extracting the water from the fruit using a variety of processes. As a result, small, dense fruits that are rich in energy and nutrients are produced and contain high levels of potassium and sugar, making them problematic for persons who have kidney disease.
  • Most beans and lentils:

  • Most beans and lentils are not recommended for people who have kidney disease because they are rich in phosphorus and potassium. If you must eat them, limit yourself to a small portion and choose low-sodium varieties.

  • Snack foods such as chips, pretzels, and crackers are high in sodium and refined sugar and low in beneficial nutrients. Snack foods should be limited or avoided in any balanced diet, especially if you have kidney disease.
  • Some leafy green vegetables:

  • Potassium and oxalic acid are rich in leafy green vegetables like spinach, beet greens, and chard. Kidney stones are more likely to form if you consume too much oxalic acid. In persons who are vulnerable to oxalates, kidney stones can form. Kidney stones can cause more damage to your kidneys and limit their function.
