On this, World Kidney Day, here are seven foods that can help keep your kidneys in good shape

As far as our diet is concerned, kidney health isn’t a top focus. However, including these common foods in your diet has been shown to improve kidney function. You can eat your way to greater kidney health by choosing certain foods. Such foods are commonplace and can be found in almost any kitchen. If you eat these foods regularly, you can reduce your risk of developing kidney disease. Dietary salt intake ought to be restricted. Diet namkeens, etc., are examples of highly processed foods that should be avoided because of their high sodium and trans fat content. In addition, because unhealthy kidneys have trouble filtering out phosphorus, a diet low in phosphorous is recommended for maintaining healthy kidneys.

The kidneys, found in one’s lower abdominal region, are relatively small but vital organs. There is some evidence that dietary patterns can affect kidney function, both positively (for the kidneys’ performance) and negatively (for the kidneys themselves). The kidneys remove harmful substances from the blood and excrete them via urine. Keeping fluid and electrolyte levels in check is another one of their responsibilities. The kidneys do all of this on their own. Their efficiency could be diminished by health problems including diabetes and hypertension. There is a risk that permanent kidney injury will result in chronic renal disease (CKD). An important element of treating chronic kidney disease is changing one’s diet, as the leading cause of death and disability from the disease, according to the authors of a 2016 paper. Maintaining optimal kidney health and preventing damage to these organs may be facilitated by eating according to a kidney-healthy diet plan. However, not all kidney disease patients can eat the foods that are known to help maintain healthy kidney function.

According to the American Kidney Fund, more than one in seven American adults suffer from chronic kidney disease (CKD), although the majority are unaware of their ailment until it has progressed significantly. Because late-stage kidney disease can produce a buildup of waste in your body and contribute to a number of other health concerns including gout, bone disease, and heart disease, it’s a good idea to safeguard your kidney health even if you haven’t been diagnosed with CKD. One of the most effective measures to protect your kidneys and slow or halt the progression of CKD is to eat a balanced diet. Here is some information about what to eat to keep your kidneys healthy.

Miniscule blood veins in the kidneys aid in the removal of waste products and excess water from the body’s circulation. A buildup of waste products in the body is a symptom of chronic kidney disease (CKD), which occurs when the kidneys are unable to filter blood effectively. The most common causes of kidney disease are diabetes and high blood pressure. Krista Maruschak, RD, a registered dietitian at Cleveland Clinic’s Center for Human Nutrition, says that high blood sugar levels in uncontrolled diabetes and high blood pressure can damage the kidneys’ blood arteries, rendering them unable to execute their job effectively. Chronic kidney disease (CKD) risk factors include uncontrolled diabetes and excessive blood pressure. The CDC reports that over 10% of Americans are diabetic, and another 33% of adults have prediabetes; also, roughly 50% of American adults aged 20 and up have hypertension. These people are also more likely to develop CKD. Maruschak argues that keeping to a healthy weight is one of the best ways to prevent or control illnesses like diabetes and high blood pressure. This, in turn, is beneficial to your kidneys.

Some foods should be added as part of a kidney-friendly diet to protect the kidneys from additional damage.

Here are seven foods that can help keep your kidneys healthy


An apple a day keeps the doctor away, and it also helps to keep your kidneys healthy. Apples’ low glycemic index and high pectin content are both protective against kidney injury. Apples are a nutritious choice since they contain a type of fiber called pectin. High blood sugar and cholesterol levels are two potential risk factors for kidney injury that pectin may help mitigate. If you have a sweet tooth, you can try eating an apple.

Eating apples regularly reduces our risk of contracting a wide range of illnesses. Apples’ anti-oxidant properties help us from getting sick. Apples are good for people of all ages, from kids to grandma. The benefits to your skin extend beyond just improved health. Kidney stones are becoming recognized as a health issue in modern society. Surprisingly, this is a widespread issue among young people. There is no immediate danger from this issue, but the associated discomfort can be severe. Apples’ anti-oxidant properties also help prevent kidney stones. If, however, you’ve developed a kidney stone, apple juice or vinegar can be a lifesaver.

Apple juice, up to 70 percent concentration, has been shown to dissolve kidney stones that are not too large or have been there for too long.


Antioxidants and beneficial nutrients can both be found in abundance in berries. Incorporating berries like strawberries, blueberries, cranberries, etc. into one’s diet has been shown to reduce the risk of renal disease. The urinary system and the kidneys both gain from consuming cranberries. These tiny, sour fruits are rich in phytonutrients known as A-type proanthocyanidins, which discourage germs from adhering to the lining of the urinary system and bladder.

One of the most nutritious foods is blueberry since it contains a high concentration of antioxidants. Particularly, the anthocyanin antioxidants found in these sugary berries have been shown to reduce the risk of cardiovascular disease, several types of cancer, memory loss, and even diabetes in animal studies. As they are low in salt, phosphorus, and potassium, they are also a great addition to a diet that is safe for people with kidney disease.

Because people with kidney illnesses are more likely to get urinary tract infections, this is helpful for them. Cranberries have several different uses and can be consumed in many different forms, including juice, dried berries, cooked berries, and fresh berries. All three essential nutrients (potassium, phosphorus, and sodium) are severely deficient.

Fruits with a high concentration of vitamin C, such as citrus

Vitamin C, in large enough doses, can help you maintain good kidney function. You can get this essential vitamin in high quantities in citrus fruits like oranges and lemons. Daily consumption of diluted lemon juice has been demonstrated to reduce the formation of stones. If you want healthy kidneys, eat more vitamin C.

Vitamin C is abundant in citrus fruits like oranges and lemons. You can reduce your chances of developing kidney stones by drinking diluted lemon juice every day.


Cabbage’s low sodium content means it’s a healthy addition to any diet, but especially one focused on warding off kidney problems. Additionally, it is rich in chemicals and vitamins that contribute to general well-being. When cooking cabbage, it’s better to keep it on the mild side so that you may get all the nutritional benefits without losing any of the flavors. To wit: vitamins, minerals, and potent plant chemicals abound in this member of the cruciferous vegetable family. Vitamin K, vitamin C, and a wide variety of B vitamins can all be found in abundance. It also contains insoluble fiber, a type of fiber that helps maintain a healthy digestive tract by encouraging frequent bowel movements and increasing stool quantity.

Sweet Potatoes

Sweet potatoes are fantastic any time of the day due to the abundance of vitamins and minerals they provide. Their high fiber content digests slowly, which makes them a good choice for weight loss as well. Compared to white potatoes, sweet potatoes are very similar, however, the higher fiber content may prolong digestion and reduce the subsequent insulin surge. The potassium found in sweet potatoes may help keep sodium levels in check and lessen the stress that sodium puts on the kidneys. However, due to its high potassium content, sweet potatoes should be used with caution by those with chronic kidney disease or who are undergoing dialysis.

Dark leafy greens

In order to improve your kidney health, you should eat more dark, leafy greens. Kale is one example of a superfood that is both easily accessible and a great source of vitamins and minerals.

Spinach, kale, and chard are just a few examples of the dark leafy greens that should form the backbone of your diet because of the abundance of vitamins, fibers, and minerals they provide. Many also have antioxidants and other beneficial chemicals. While delicious, these meals are often high in potassium and may not be appropriate for those with dietary restrictions or who are on dialysis.


Cauliflower is a superfood because it is rich in vitamin C, folate, and fiber. To maximize its kidney-boosting effects, it can be consumed either boiled or raw. Dr. Shilpa Arora, a nutritionist, suggests that a diet high in foods high in water content may be helpful to health. Shilpa Arora recommends consuming the following foods to maintain healthy kidneys: celery, Kakadu, cucumber, bottle gourd, and watermelon. The consultant also suggests trying coconut water. Because of its high potassium content and its ability to aid in the excretion of sodium, “coconut water is incredibly therapeutic for the kidneys.

Vitamin C, vitamin K, and B vitamin folate are just a few of the many vitamins and minerals that may be found in abundance in this healthy vegetable. It’s a great source of fiber and contains anti-inflammatory chemicals like indoles. In addition, mashed cauliflower can be used as a low-potassium substitute for potatoes.

The Bottom Line

The items mentioned above are highly recommended for those on a renal diet. Be sure to consult your doctor about your diet to ensure it’s right for your health. Restrictions on what a person with renal disease can consume range from mild to severe, and from medication to dialysis. A renal diet may seem limited at first, but it’s possible to eat a nutritious, balanced, kidney-friendly diet without sacrificing flavor. There are a number of chemical reactions in your body that necessitate the minerals phosphorus and potassium. Phosphorus aids in bone development, whereas potassium ensures a regular heartbeat and healthy muscle function. However, if you have chronic kidney disease (CKD), these minerals can accumulate in your blood, leading to a wide range of health issues. Phosphorus deficiency can cause the skin to itch and bone and joint discomfort, while phosphorus excess can weaken bones and increase the risk of fracture. Foods high in phosphorous, such as animal protein, dairy, and dark-colored drinks, may need to be limited. Potassium, found in many fruits and vegetables as well as in dairy products, can be harmful to the heart if consumed in excess. The doctor will check your blood for potassium and phosphorus levels. If you are unsure about whether or not you need to monitor your intake of these minerals, be sure to inquire.

Sometimes it’s difficult to alter one’s eating habits. Getting the assistance of a licensed dietitian (RD) might be quite useful if you’re having trouble maintaining a healthy diet.
