Foods for a Healthy Kidney, a Diet Plan, Risks, and More

Foods for a Healthy Kidney

With the passage of time, an increasing number of people are becoming afflicted with renal disease. Almost 10% of the world’s population is affected by them. When you have renal illness, you are not allowed to eat certain foods.

The kidneys are bean-shaped organs that are small but powerful. They filter waste, release hormones to regulate blood pressure, and maintain fluid balance.

They also create urine and carry many other essential functions. As a result, if you have renal illness, you must take care of your dietary requirements. You must also improve their long-term performance.

This page discusses renal-friendly foods as well as a general diet for kidney patients. For a tailored diet, you can visit a licenced dietitian or a nutritionist at HealthifyMe. Continue reading to learn about kidney-friendly foods, diet, and other topics.

If your kidneys aren’t performing as well as they should, your body may accumulate waste and fluid. It can lead to heart, bone, and other health issues over time.

The basic goal of a kidney-friendly diet is to reduce the amount of particular minerals and fluids you consume. It may aid in the prevention of waste and fluid accumulation, as well as the accompanying problems.

The restrictions are determined by your stage of kidney disease. You may have few or no restrictions on what you eat and drink in the early stages of renal disease. However, when your kidney condition worsens, your doctor may advise you to decrease your intake of phosphorus, potassium, and water.

Kidney-Friendly Foods

The foods listed below may help you prevent and protect against kidney disease. Please keep in mind that these foods are only for persons who have kidney disease and no other medical disorders such as diabetes or high blood pressure.

The gourds

Gourds are known as the “Gods of Vegetables” for kidney disorders. Bottle gourd, snake gourd, ridge gourd, striped gourd, bitter gourd, and other gourds are among the many varieties of gourds. These gourds have low salt and potassium levels. As a result, they are appropriate for intake by patients suffering from kidney disease.

They can be eaten as a vegetable sabzi with rice or roti, or they can be cooked with rice. They can also be used as a filling for parathas.

However, keep in mind that when cooking for a renal patient, your vegetable preparations or curries should not be extremely fluid. It is due to fluid constraints in kidney sufferers. As a result, you should boil the vegetables thoroughly and avoid adding water while they are cooking.

Red bell peppers

Red, green, and yellow capsicums are all useful to kidney sufferers. They include phytochemicals and antioxidants, which aid in the reduction of inflammation in the body. Antioxidants aid in repair by lowering stress.

These veggies are also low in potassium, sodium, and fluid, which reduces the load on the kidneys. Reduced kidney load aids in the healing and regeneration of nephrotic cells.

Foods High in Carbohydrates

Because proteins cannot be included in the diet, you should increase carbohydrate consumption to meet the body’s energy needs.

The carbohydrate sources listed above can be used to make both sweet and savoury foods. However, keep in mind that the things listed above frequently come in two varieties.

One is refined carbohydrate, and the other is whole or multigrain carbohydrate, commonly known as complex carbohydrate. It is dependent on the individual’s condition whether or not they can withstand a complex structure. Typically, the streamlined form is appropriate for all patients.

Species of Allium

Allium species include onions, garlic, and spring onions, among others. According to study, these meals preserve the kidneys. These species contain a variety of antioxidants that help to minimise oxidative stress in the body.

In addition, eating these veggies increases the number of angiotensin receptors in the body. The increased number of angiotensin receptors slows the progression of chronic renal disease.

These species are also referred to as allicin. According to one study, allicin therapy alleviates renal impairment.

All vegetables should be leached before cooking. Leaching implies boiling the veggies for 2-3 minutes in hot water and then immediately transferring them to a bowl of cold water. The potassium content of plants is reduced as a result of this procedure.

Milk (in restriction)

Milk and milk products are high in protein. Proteins, on the other hand, should be avoided in kidney problems. As a result, even if you incorporate dairy products in your diet, you should do so in moderation.

It will be beneficial to take these dosages after speaking with a trained nutritionist. Moderate dairy product consumption may protect against chronic kidney disease.

Fruits and vegetables

The following fruits are permitted in renal disease:

  • Apple
  • Pineapple
  • Papaya
  • Guava
  • Banana

These fruits are low in salt and potassium, and they aid to reduce renal stress. Citrus fruits may be permitted depending on the degree of fluid intake permitted by the doctor.

People who do not have diabetes can consume the aforementioned fruits. People with diabetes, on the other hand, must take fruits with caution.

Foods to Avoid If You Have Kidney Disease

Dietary restrictions in renal disease are determined mostly by the severity of the disease. However, there are three types of meals that you should avoid:

Foods High in Phosphorus

It is a mineral that can be found in a variety of foods. When your kidneys function properly, they work with calcium and vitamin D to keep your bones healthy. When your kidneys aren’t performing properly, phosphorus can build up in your blood.

Too much phosphorous in your blood can cause weak, easily broken bones. As a result, many persons with renal disease must limit their intake of phosphorus.

Avoid phosphorus-rich meals such as:

  • Bread with whole grains
  • Oatmeal and bran cereals
  • Sunflower seeds and nuts
  • Colas in dark colours

Instead, eat low-phosphorus meals such as:

Bread might be Italian, French, or sourdough.
Cereals made from corn or rice, as well as cream of wheat
Popcorn without salt

Foods High in Potassium

Your body requires potassium to function properly, but too much potassium can be harmful. When your kidneys aren’t performing properly, your potassium levels can skyrocket or plummet. Too much or too little potassium, on the other hand, can induce muscle cramps, irregular heartbeats, and muscle weakness.

If you have kidney disease, you may need to restrict your potassium intake.

Potassium-rich foods to avoid include:

  • Avocados, bananas, melons, oranges, prunes, and raisins are all examples of fruits.
  • Artichokes, winter squash, plantains, spinach, potatoes, and tomatoes are just a few of the vegetables on the menu.
  • Granola and bran goods
  • Brown or wild rice, beans (baked, black, pinto, etc.)

Instead, eat low potassium meals such as:

  1. Apples, cranberries, grapes, pineapples, and strawberries are all examples of fruits.
  2. Cauliflower, onions, peppers, radishes, summer squash, and lettuce are some of the vegetables used in this recipe.
  3. Pita, tortillas, and white bread are all options.
  4. White rice, beef and chicken


You need water to live, but if you have kidney disease, you may not require as much since damaged kidneys do not excrete additional fluid.

Furthermore, extra fluid in your body can be harmful, causing high blood pressure, edoema, and heart failure. Excess fluid can also accumulate around your lungs, making it difficult to breathe.

If you have renal illness and are receiving therapy, you may need to limit your fluid consumption. You may also need to limit your intake of some foods that are high in water.

Soups and meals that melt, such as ice, ice cream, and gelatin, contain a lot of water. Many fruits and vegetables are also high in water content.

Reduce your sodium intake to help reduce thirst. You may still feel thirsty at times. You could try the following to quench your thirst:

  • Gum chewing
  • Floss your teeth
  • Suck on some ice, mints, or hard candy (Remember to choose sugar-free candy if you have diabetes.)

Other Things to Avoid

  • Protein concentrations such as whey protein isolates, for example.
  • Meat that is red
  • Spinach, lettuce, amaranth, and kale are examples of green leafy vegetables.
  • Nuts should be avoided.
  • Citrus fruits, such as orange, watermelon, and lime, have a high water content.
  • Beverages with carbonation
  • Mayonnaise, salted butter, tinned fish, and other canned foods contain a lot of sodium and potassium.
  • Fruits and vegetables high in sodium and phosphorus may also be prohibited. It is case-by-case, depending on individuality.


Each human body has unique requirements. The same is true for those suffering from renal disorders. Kidney problems progress over time. It can be lethal if not controlled at an early stage.

As a result, a customised renal diet and medicines are required. They will make certain that the situation does not deteriorate. It will also aid in kidney repair and healing.

In conclusion

The page provides a broad overview of renal issues and renal nutrition. A person with renal/kidney difficulties should seek the advice of a certified dietitian or nutritionist for a personalised diet.

This customised diet will be based on their needs and the needs of their bodies. For persons with kidney difficulties, for example, only five fruits are permitted: apple, pineapple, papaya, guava, and banana. Protein intake is likewise limited. Foods high in salt and potassium are also prohibited.
