The 5 Best Foods for People with Kidney Disease

1. Cauliflower

Cauliflower is a nutritious vegetable that’s a good source of many nutrients, including vitamin C, vitamin K, and the B vitamin folate.

It’s also full of anti-inflammatory compounds like indoles and is an excellent source of fiber (17Trusted Source).

Plus, mashed cauliflower can be used in place of potatoes for a low potassium side dish.

One cup (124 grams) of cooked cauliflower contains (18):

• sodium: 19 mg
• potassium: 176 mg
• phosphorus: 40 mg

2. Blueberries

Blueberries are packed with nutrients and one of the best sources of antioxidants you can eat (19Trusted Source).

In particular, these sweet berries contain antioxidants called anthocyanins, which may protect against heart disease, certain cancers, cognitive decline, and diabetes (20).

They also make a fantastic addition to a kidney-friendly diet, as they are low in sodium, phosphorus, and potassium.

One cup (148 grams) of fresh blueberries contains (21):

• sodium: 1.5 mg
• potassium: 114 mg
• phosphorus: 18 mg

3. Sea bass

Sea bass is a high quality protein that contains incredibly healthy fats called omega-3s.

Omega-3s help reduce inflammation and may help decrease the risk of cognitive decline, depression, and anxiety (22Trusted Source, 23Trusted Source, 24Trusted Source).

While all fish are high in phosphorus, sea bass contains lower amounts than other seafood.

However, it’s important to consume small portions to keep your phosphorus levels in check.

Three ounces (85 grams) of cooked sea bass contain (25):

• sodium: 74 mg
• potassium: 279 mg
• phosphorus: 211 mg

4. Red grapes

Red grapes are not only delicious but also deliver a ton of nutrition in a small package.

They’re high in vitamin C and contain antioxidants called flavonoids, which have been shown to reduce inflammation (26Trusted Source).

Additionally, red grapes are high in resveratrol, a type of flavonoid that has been shown to benefit heart health and protect against diabetes and cognitive decline (27Trusted Source, 28Trusted Source).

These sweet fruits are kidney-friendly, with a half cup (75 grams) containing (29):

• sodium: 1.5 mg
• potassium: 144 mg
• phosphorus: 15 mg

5. Egg whites

Although egg yolks are very nutritious, they contain high amounts of phosphorus, making egg whites a better choice for people following a renal diet.

Egg whites provide a high quality, kidney-friendly source of protein.

Plus, they’re an excellent choice for people undergoing dialysis treatment, who have higher protein needs but need to limit phosphorus.

Two large egg whites (66 grams) contain (30):

• sodium: 110 mg
• potassium: 108 mg
• phosphorus: 10 mg
