The kidneys are responsible for many functions within the body, such as filtering waste out of the blood, balancing the body’s fluid and electrolyte levels, and so much more. Therefore, maintaining kidney health is crucial to overall health and wellness. One of the best ways to boost your kidney health is by consuming a diet with kidney-friendly superfoods packed with nutritional benefits. 

Here are 4 kidney health-boosting foods you can incorporate into your diet.


Apples are not only delicious but provide a range of health benefits. These fruits are rich in fiber, vitamins and minerals, which are considered essential nutrients that help boost the immune system, promote normal growth and development and so much more. 

Apples are a great source of pectin, a type of soluble fiber that has several potential health benefits. One study found that pectin may be used to design drugs for the complex treatment in patients with chronic renal failure. 


Fatty fish, such as sardines, tuna, salmon, and anchovies, are high in omega-3 fatty acids. The human body doesn’t produce omega-3 fatty acids, which is why it is important to get this nutrient from food or supplements. Benefits of incorporating omega-3 fatty acids in your diet include:

  • Reduces the risk of cardiovascular disease
  • Lowers blood pressure
  • Slows the development of plaque in the arteries
  • Lowers triglyceride levels in the blood

Dark leafy greens

It should be no surprise that green vegetables are a staple in any balanced diet. Dark leafy greens, such as spinach or kale, are packed with vitamins and minerals that promote healthy kidney function. These vegetables also contain antioxidants which can help make the kidneys’ job of filtering out the blood easier.

Some leafy greens, however, contain high levels of potassium. While potassium is an important mineral for the body, too much potassium can be dangerous for individuals with kidney damage from chronic kidney disease. Kale and spinach are considered medium to high potassium food choices, so it is important that consumption is limited by people on dialysis or those with a dietary potassium restriction.


Cranberries are small, tasty and tart red fruits that grow on vines in freshwater. They are widely consumed dried, as a juice or sauce, or in supplements. Cranberries have been shown to benefit the urinary tract. According to research, cranberries contain A-type proanthocyanidins (PACs) that can prevent bacteria from sticking to the bladder wall, which could potentially stop UTI’s from occurring or help a person recover from one faster. Other research indicates that the nutrients in cranberries may prevent certain types of cancer, improve immune function and decrease blood pressure.
