The kidneys are essential organs that help filter waste and excess fluids from the blood, while also balancing key minerals like potassium and phosphorus. To keep them functioning well, a healthy diet plays an important role. If you want to maintain your kidney health or reduce the risk of kidney damage, making better food choices can be a great step forward.
However, before making any major changes to your diet, it’s important to talk to your doctor—especially if you have or are at risk for kidney disease. Below are some kidney-friendly food options to consider adding to your meals.
Foods for a Renal Diet
1. Red Bell Peppers
Red bell peppers are a fantastic choice for people with kidney concerns. They are low in potassium, so they won’t overload your kidneys with excess minerals. These colorful veggies are also packed with lycopene, a powerful antioxidant that can support heart health and reduce inflammation. Lycopene has also been linked to a lower risk of certain cancers.
How to Enjoy: Try adding red bell peppers to salads, sandwiches, or pasta dishes to boost flavor without sacrificing your kidney health.
2. Cabbage
Cabbage is another kidney-friendly food that is low in potassium. It’s also an excellent source of fiber and vitamin K, which is essential for blood clotting and strong bones. Because it’s so versatile, cabbage can fit into many different types of meals.
How to Enjoy: Add cabbage to soups, stews, salads, or use it as a crunchy topping for tacos or sandwiches.
3. Apples
Apples are not only delicious but also kind to your kidneys. They are low in potassium, sodium, and phosphorus, making them a perfect snack for people managing kidney disease. Apples are also high in fiber and vitamin C, which support overall health.
How to Enjoy: Keep an apple handy as a healthy, satisfying snack throughout the day.
4. Cranberries
Cranberries are another great option for a renal diet. They are low in potassium and rich in vitamin C, which supports immune health. Cranberries also contain compounds that can help prevent urinary tract infections (UTIs), which are common in people with kidney disease.
How to Enjoy: Add fresh or dried cranberries to oatmeal, sprinkle them on salads, or drink cranberry juice (just be sure it’s low in potassium).

Cherries aren’t just delicious—they’re also anti-inflammatory, which can be beneficial for kidney health. Low in sodium and phosphorus, cherries help support kidney function while offering important nutrients like fiber and vitamin C.
How to Enjoy: Enjoy cherries as a sweet snack or try dried cherries as a healthy addition to salads or trail mix.
7. Tuna
Tuna is a great source of protein, especially for those with kidney disease, as it’s low in phosphorus. It also provides omega-3 fatty acids, which are known to help reduce inflammation and support heart health. Just make sure to choose low-sodium varieties to keep your sodium intake in check.
How to Enjoy: Add canned albacore tuna to salads, wraps, or sandwiches for a kidney-friendly protein boost.

Like tuna, salmon is an excellent protein source for kidney health. It’s rich in omega-3 fatty acids, which help lower inflammation and support heart health, while being low in saturated fats.
How to Enjoy: Bake, grill, or pan-sear salmon for a tasty meal. Pair it with a side of vegetables or whole grains for a balanced kidney-friendly dish.
9. Buckwheat
Buckwheat is a great choice for those looking for a whole grain that is low in both phosphorus and potassium. This nutrient-dense grain provides fiber, magnesium, and iron—making it a healthy addition to a renal diet.
How to Enjoy: Use buckwheat in place of rice or pasta, or try buckwheat pancakes for breakfast.
10. Radishes
Radishes are not only low in potassium but also pack a punch of flavor. They’re high in fiber and vitamin C, and they can help with digestion, which is important for overall kidney health.

Pineapple is a sweet, kidney-friendly fruit that is low in potassium. It also contains an enzyme called bromelain, which can help reduce inflammation in the body. Plus, it’s rich in vitamin C, which supports immune health.
How to Enjoy: Add pineapple slices to smoothies, stir-fries, or enjoy it fresh for a tropical treat.
12. Shiitake Mushrooms
For those looking to cut back on animal protein, shiitake mushrooms are a great plant-based option. They’re low in both phosphorus and sodium, while providing a good amount of protein and other nutrients.

15. Chicken
Chicken is a great source of lean protein, but it’s important to choose lower-sodium options. Skinless chicken breast is particularly kidney-friendly as it contains less sodium, phosphorus, and potassium compared to other cuts.
