Top Healthy Foods For People With Kidney Disease

Kidneys are really important workhorses in the body. The small, bean-shaped organs filter waste products from the blood. They also release hormones that regulate blood pressure, help to balance bodily fluids, and create urine. Kidney disease affects about 10% of the world’s population and can be caused by high blood pressure and uncontrolled blood sugar. Other factors like age, smoking, obesity, and gender also play a part. When the kidneys aren’t functioning optimally, waste products from food build up in the blood and make the body quite ill.


The diet that must be followed by people with kidney disease varies a lot based on its stage. Early stages have different restrictions than people with end stage renal disease. Beyond dietary changes, you may need dialysis and possibly a kidney transplant. If you have been diagnosed with kidney disease or if it runs in your family, it is smart to educate yourself on the best healthy food choices. We’ve got a list of safe things to eat with kidney disease, but please consult with your doctor for the best amount and combination of these foods for your particular situation.

Before we dig into the good stuff, know that in general, people with kidney disease will be asked to limit certain nutrients that are found in a lot of different foods. The three big ones are sodium, potassium, and phosphorus. Protein may be limited in the early stages of kidney disease and increased in patients whose condition is more advanced and requires dialysis. As a start, here is a list of tasty and healthy foods that are low in phosphorus, potassium, and sodium.

1. Cauliflower
Cauliflower is a vegetable full of vital nutrients like vitamin C, vitamin K, and folate (B vitamin). It also has a nice amount of fiber to help with digestion and certain anti-inflammatory compounds called indoles. Cauliflower can be eaten raw or roasted, even mashed in the place of potatoes.


In one cup (124 grams) of cooked cauliflower:

Sodium: 19 mg
Potassium: 176 mg
Phosphorus: 40 mg

2. Blueberries
Blueberries are one of the best fruits you can eat for your whole body. They are high in antioxidants called anthocyanins, which help reduce risk of heart disease, diabetes, cognitive decline, and certain cancers. They are also fantastic for kidney patients as they are low in sodium, phosphorus, and potassium.

In one cup (148 grams) of fresh blueberries:

Sodium: 1.5 mg
Potassium: 114 mg
Phosphorus: 18 mg

3. Sea Bass
Sea bass is recommended for people with kidney disease because it is a high-quality protein that contains healthy omega-3 fats with a lower level of phosphorus than other seafood. It is still important to consume sea bass in moderation, but a diet rich in omega-3s also helps to moderate depression, anxiety, and cognitive decline.

In three ounces (85 grams) of cooked sea bass:

Sodium: 74 mg
Potassium: 279 mg
Phosphorus: 211 mg

4. Red Grapes
Red grapes are high in vitamin C and contain antioxidants called flavonoids, which reduce inflammation in the body. They also feature a particular kind of flavonoid called resveratrol, which is touted for its ability to benefit the heart, regulate blood sugar, hold off cognitive decline, and protect the skin from sun exposure and aging.

In ½ cup of red grapes:

Sodium: 1.5 mg
Potassium: 144 mg
Phosphorus: 15 mg

5. Egg Whites
Egg yolks are highly nutritious, but also contain a lot of phosphorus, so folks with kidney disease do best to stick to the whites. Egg whites are high in protein but low in phosphorus, so they are often especially recommended for people who are undergoing dialysis. Dialysis patients typically have higher protein needs.

In two large egg whites (66 grams):

Sodium: 110 mg
Potassium: 108 mg
Phosphorus: 10 mg

6. Garlic
Because kidney problems require a reduction in sodium, you may be worried about losing the enjoyment of flavorful food, too. Luckily, garlic is a wonderful alternative to salt that also offers its own nutritional benefits. Garlic contains vitamin C, vitamin B6, manganese, and certain sulphur compounds that are anti-inflammatory.

In three cloves (9 grams) of garlic:

Sodium: 1.5 mg
Potassium: 36 mg
Phosphorus: 14 mg


7. Buckwheat
Whole grains are a vital part of a healthy diet, but many of them are high in phosphorus. Buckwheat is an excellent alternative. It offers nutrition in the form of magnesium, iron, fiber, and B vitamins. As a bonus, it is gluten-free and safe for people with gluten intolerance, all while containing very low amounts of the things you need to avoid.

In ½ cup (84 grams) of cooked buckwheat:

Sodium: 3.5 mg
Potassium: 74 mg
Phosphorus: 59 mg

8. Olive Oil
Olive oil not only contains healthy fats, it is entirely free of phosphorus. It is especially good for people with kidney disease because they tend to have trouble maintaining a healthy weight. The fat in olive oil is mostly a monounsaturated version called oleic acid, which can also reduce inflammation. It is good for cooking because it can withstand high temperatures, but also great in salad dressings.

In one ounce (28 grams) of olive oil:

Sodium: 0.6 mg
Potassium: 0.3 mg
Phosphorus: 0 mg

9. Arugula
Conventional nutrition information suggests lots of dark leafy greens like spinach and kale. While these are extremely healthy foods, they are also high in potassium and therefore not recommended on a renal diet. Arugula is a great alternative. It is both low in potassium and high 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.

One cup (20 grams) of raw arugula contains:

Sodium: 6 mg
Potassium: 74 mg
Phosphorus: 10 mg

Again, your doctor will give you specific guidelines for your diet with kidney disease, but we hope we have given you a good idea of some whole foods and ingredients that can combine into healthy, flavorful meals. Most packaged foods contain way too much sodium, but it can feel really good to stretch your culinary talents and prepare fresh kidney-friendly meals from scratch. Go for it, you won’t be sorry!


Early Signs of Kidney Disease And How To Protect Your Kidneys (Evidence Based)

Kidney disease is a serious medical issue with an unfortunate prevalence in our society. According to the medical journal, Primary Care, chronic kidney disease (CKD) is a major health problem affecting approximately 13% of the United States population.


The scientific journal, Kidney International Supplements, advises that some of the risk factors for kidney disease are high blood pressure, excessive alcohol consumption, smoking, and the use of analgesic medications.

The Importance of Kidneys
The kidneys are bean-shaped organs and they are one of the most important organs in our body. The journal of Physiology describes the kidneys as “an organ of critical importance in physiology.”

The kidneys are made to function in several ways to ensure the healthy function of your internal processes. Your kidneys are located in the middle of your back against the back muscles, with one on either side of your spine.

The kidneys filter out any harmful waste and excess toxins while balancing blood pressure and essential nutrients.

Without the kidneys our bodies wouldn’t be able to:
  • Keep water and essential minerals balanced in the bloodstream.
  • Maintain a healthy blood pressure.
  • Extract chemicals and waste that come from the digestion process, taking medication, and physical exertion.
  • Activate vitamin D for healthy bones.
  • Increase the production of red blood cells to deliver oxygen through the body.
Even bodily processes like metabolic function produce waste products that are harmful for the body. Risk factors surround us and happen regularly within our own body, but with our kidneys at work we don’t have to worry about them.

What Causes Kidney Disease
As mentioned earlier, some diseases can serve as a predisposition for kidney disease.

According to medical journal of Renal Injury Prevention, diabetes and high blood pressure issues are the top causes of kidney disease.

If you have a high blood pressure stay mindful of the possibility of kidney problems in the future. When you visit the doctor keep a close watch over your blood sugar and blood pressure levels and ask the physician if they are normal.


According to medical studies, kidney disease can also be passed on through genetic issues.

If your family has a history of autoimmune disease or polycystic kidney disease you are more vulnerable to kidney problems in the future.

Birth defects and improper use of medication can cause kidney damage and renal disorders.

Harmful habits like drinking, smoking, poor diet, and lack of exercise are also a major cause of kidney disease.

Early Signs and Symptoms of Kidney Disease
The trouble with kidney disease is that many people fail to act upon the issue until the condition has become severe.

The symptoms of kidney damage can be a tad general in the early phase, allowing someone to simply brush them off or associate them with some other illness.

Your kidneys also have a great ability to adapt to the disease as they lose function.

Doctors from the Mayo Clinic say that some of the symptoms of kidney disease or kidney failure are:
  • Feeling easily tired and experiencing a lack of strength
  • Changes in urination, such as blood in the urine or changes in the amount and number of times urine is passed
  • Troubles with sleeping
  • Nausea and vomiting
  • Irregularities in the digestive routine
  • Lack of interest in eating food and bad metallic taste in the mouth
  • Lack of focus and mental clarity
  • Hiccups
  • Swollen ankles or feet
  • Pain above the waist in the back of the body (where the kidneys are located)
  • Muscle spasms and cramping
  • Unstable blood pressure
  • Loss of breath
  • Skin rash or chronic itching
Detecting these signs early on is essential. If kidney problems aren’t addressed early on, then the damage can quickly become irreversible. Nobody wants to have to go through dialysis and treatment for the disease.

If you show some of these symptoms or worry that you might have a susceptibility to kidney issues, consult with a physician immediately.

The symptoms of kidney disease are fairly general so there is a chance they could be from some other illness. It’s never too safe to be sure, and the sooner you tackle kidney disease the better.

How to Strengthen Your Kidneys
A few small changes in your everyday life can lead to a life-saving difference down the road. These five changes to your lifestyle and nutrition will reduce your risk of disease by protecting your kidneys.


Lifestyle Changes to Protect Your Kidneys

1. Blood pressure plays a big part in kidney function. Keeping your blood pressure at a healthy level (around 120/80) will help reduce damage to the kidneys.

2. Smoking and drinking should be avoided because they wreak havoc on your kidneys. For example, the American Journal of Epidemiology, found that “smoking and consumption of four or more servings of alcohol per day are associated with CKD (Chronic Kidney Disease).”

3. Get active with more exercise. It will strengthen your entire body and give you more energy. It will help you keep optimal body weight and reduce your risk of obesity, diabetes and hypertension that can damage the kidneys over time.

4. Consider supplements that provide calcium and vitamin D if you feel you don’t get enough on a daily basis. Always consult with your doctor before taking them.

5. Limit using painkillers and steroids and only use them when you feel they are absolutely necessary. For example, the medical journal, Pharmaceuticals (Basel), found that “NSAIDs pose a significant risk of renal failure for significant duration and as an entity may be under-recognized.”

Nutritional Changes to Protect Your Kidneys

1. Stay mindful of your sodium intake. Keep the salt and potassium you ingest at a moderate level.

2. Maintain a healthy nutrition. Eat meals with small amounts of cholesterol and saturated fat.

3. Maintain low protein diet. Too much protein consumption is bad for the kidneys. Ask your physician how much you should eat daily according to your body type.

4. A sufficient amount of calories is necessary for the kidneys, so starving yourself for weight loss isn’t a great idea.

5. Watermelons, apples and berries are among the foods that should be at the top of your grocery list.

6. Stay hydrated. Drink about 8 glasses of fluid, preferably water, every day. Not drinking enough water is one of the common habits that can damage your kidneys,

Kidney disease is a sobering reality that plagues many thousands of families every single year. Damage to the kidneys can’t be repaired but it can be lived with if detected early enough – though prevention is the best choice.

Taking responsibility over your own health isn’t just for yourself. It’s for the friends and family you treasure and the impact your life can have on the world when it is lived to the fullest.
