Kidneys are really important beasts of burden in the body. Small kidney-shaped organs filter waste products from the blood. They also release hormones that regulate blood pressure, help balance body fluids, and create urine. Kidney disease affects about 10% of the world population and can be caused by rich blood pressure and uncontrolled blood sugar. Other factors such as age, smoking, obesity, and gender also play a role. When the kidneys do not function optimally, food waste accumulates in the blood and seriously ills the body.
The diet that people with kidney disease must follow varies greatly according to their stage. The early stages have different restrictions than people with end-stage kidney disease. Beyond dietary changes, you may need dialysis and possibly a kidney transplant. If you have been diagnosed with kidney disease or if it works in your family, it is a good idea to find out what are the best healthy food options. We have a list of safe things to eat with kidney disease, but ask your doctor about the best amount and combination of these foods for your particular situation.
Before digging into good things, keep in mind that, in general, people with kidney disease will be asked to limit certain nutrients found in many different foods. The big three are sodium, potassium, and phosphorous. Protein can be limited to the early stages of kidney disease and increased in patients who are more advanced and require dialysis. To start, here is a list of tasty and healthy foods low in phosphorous, potassium, and sodium.
Because kidney problems require sodium reduction, you may also fear to lose the pleasure of tasty meals. Fortunately, Garlic is a wonderful alternative to salt that also has its own nutritional benefits. Garlic contains vitamins C, B6 manganese, and certain anti-inflammatory compounds that fight sulfur.
18 grams of garlic:
- Sodium: 3 mg
- Potassium: 72 mg
- Phosphorus: 28 mg
Classic nutritional information suggests many dark leafy vegetables like spinach and kale. Although these foods are extremely healthy, they are also high in potassium and therefore not recommended as part of a kidney diet. Rocket is a great alternative. It is low in potassium and rich in vitamin K, manganese and calcium. It also contains nitrates, which are known to lower blood pressure, another important consideration for people with kidney disease.
60 grams of raw arugula contains:
- Sodium: 18 mg
- Potassium: 222 mg

Red Grapes Red grapes are rich in vitamin C and contain antioxidants called flavonoids, which reduce inflammation in the body. They also contain a special type of flavonoid called resveratrol, which is known for its ability to benefit the heart, regulate blood sugar, slow cognitive decline, and protect skin from sun exposure and aging.
In ½ cup of red grapes:
- Sodium: 1.5 mg
- Potassium: 144 mg
- Phosphorus: 15 mg
yellow Egg is very nutritious, but they also contain a lot of phosphorus, so people with kidney disease prefer whites. Egg whites are high in protein but low in phosphorus, which is why they are often recommended especially for people on dialysis. Dialysis patients generally have higher protein requirements.
In one large egg whites (33 grams):
- Sodium: 55 mg
- Potassium: 54 mg
- Phosphorus: 5 mg
Cauliflower is a vegetable full of essential nutrients like vitamins C, K and (vitamin B) folic acid. It also contains a good amount of fiber to aid digestion and certain anti-inflammatory compounds called indoles. Cauliflower can be eaten raw or roasted, even mashed instead of potatoes.
248 grams) of cooked cauliflower :
- Sodium: 38 mg
- Potassium: 352 mg

Sea bass is recommended for people with kidney disease because it is a high-quality protein that contains healthy omega-3 fatty acids with a lower phosphorus level than other shellfish. Consuming sea bass in moderation is always important, but a diet rich in omega-3s also helps moderate depression, anxiety, and cognitive decline.
42 grams of cooked sea bass :
- Sodium: 37 mg
- Potassium: 139 mg
- Phosphorus: 105 mg
Whole grains are an essential part of a healthy diet, but many of them are rich in phosphorous. Buckwheat is a great alternative. It provides nutrition in the form of magnesium, iron, fiber, and B vitamins. As an added benefit, it is gluten-free and safe for people with gluten intolerance, while containing very small amounts of things to avoid.
168 grams of cooked buckwheat :
- Sodium: 7 mg
- Potassium: 148 mg

Blueberries are one of the best fruits you can eat for your entire body. They are rich in antioxidants called anthocyanins, which help reduce the risk of heart disease, diabetes, cognitive decline, and certain types of cancer. They are also great for kidney patients because they are low in sodium, phosphorous, and potassium.
296 grams of fresh blueberries :
- Sodium: 3 mg
- Potassium: 228 mg
- Phosphorus: 36 mg
Olive oil does not only contain healthy fats, but is completely phosphorous-free. This is especially good for people with kidney disease, as they tend to have trouble maintaining a healthy weight. The fat in olive oil is primarily a monounsaturated version called oleic acid, which can also reduce inflammation. It is good for cooking because it can withstand high temperatures, but also excellent in salad dressings.
84 grams of olive oil :
- Sodium: 1.8 mg
- Potassium: 0.9 mg
