A Healthy Kidney Diet: What Not To Include

Foods To Cleanse and Repair Your Liver and Kidney Health ...

A diet comprised of foods good for your kidneys includes antioxidant-rich foods that aim to keep swelling and bloating at a minimum. If you already suffer from kidney dysfunction or renal failure, below are the types of foods to limit consuming in order to keep your kidneys as healthy as possible:

  • Limit Protein. Foods high in protein including turkey, chicken, eggs, milk, cheese, and yogurt, can create more work for your kidneys. By limiting your protein intake, you can reduce the amount of waste in your blood.
  • Limit Phosphorous. Phosphorous may sound scary, but its actually a common mineral found in beans, peas, nuts, whole grains, dairy products, beer, and some soft drinks. When your kidneys dont work properly, the phosphorous in these foods cant work their way out of your bloodstream fast enough, which can weaken your bones and essentially eat away at the calcium.
  • Limit Sodium. It seems challenging to avoid sodium these days, as its a common preservative found in many supermarket items. When you are at risk of kidney failure, however, salty foods are not your friend. A diet high in sodium can elevate blood pressure, putting you at risk of cardiovascular health concerns as well. In order to eat a healthy kidney diet, avoid adding table salt to your food, canned foods and soups, and deli meats.

    What Is A Renal Diet

    Unfortunately there is no permanent treatment/cure for kidney failure, only strategies to keep someone with kidney disease as stable and healthy as possible. One of these strategies is following a kidney disease diet that limits intake of certain nutrients, in order to cut down on the amount of waste in their blood. Thats because the kidneys are needed to properly balance ratios of water, salt and other minerals in the blood therefore, kidney dysfunction can lead to abnormal mineral levels.

    What does a renal diet mean? A renal diet eating plan is one that restricts sodium, potassium and phosphorus intake, since people with kidney disease/kidney issues need to monitor how much of these nutrients they consume. These three micronutrients can accumulate in the blood and contribute to problems like high blood pressure , swelling and fluid retention, heart arrhythmias , bone disorders, and vascular calcifications.

    Based on recent research findings, some experts worry that prescribing the traditional renal diet to patients encourages them to eat Western-type diets instead that are high in red meat, packaged products made with lots of preservatives and additives, and foods made with refined grains and sugars.

    Potatoes And Sweet Potatoes

    Health » Pharmacy

    Potatoes and sweet potatoes are potassium-rich vegetables.

    Just one medium-sized baked potato contains 610 mg of potassium, whereas one average-sized baked sweet potato contains 541 mg of potassium .

    Fortunately, some high potassium foods, including potatoes and sweet potatoes, can be soaked or leached to reduce their potassium contents.

    Cutting potatoes into small, thin pieces and boiling them for at least 10 minutes can reduce the potassium content by about 50% .

    Potatoes that are soaked in water for at least 4 hours before cooking are proven to have an even lower potassium content than those not soaked before cooking .

    This method is known as potassium leaching or the double-cook method.

    Although double cooking potatoes lowers the potassium content, its important to remember that their potassium content isnt eliminated by this method.

    Considerable amounts of potassium can still be present in double-cooked potatoes, so its best to practice portion control to keep potassium levels in check.


    Potatoes and sweet potatoes are high potassium vegetables. Boiling or double cooking potatoes can decrease their potassium content by about 50%.

    Tomatoes are another high potassium fruit that may not fit the guidelines of a renal diet.

    They can be served raw or stewed and are often used to make sauces.

    Just 1 cup of tomato sauce can contain upwards of 900 mg of potassium .

    Unfortunately for those on a renal diet, tomatoes are commonly used in many dishes.

    Improve KIDNEY FUNCTION with This DIET – 2021

    The kidneys are filled with tiny blood vessels that help filter waste and extra water from your blood and remove them from your body. If you have CKD, your kidneys cant filter blood as well as they should, causing excess waste to build up in your body.

    Diabetes and hypertension are the two leading causes of kidney disease. High blood sugar levels in uncontrolled diabetes and high blood pressure can damage the kidneys blood vessels, leaving them unable do their job properly, says Krista Maruschak, RD, a registered dietitian with Cleveland Clinics Center for Human Nutrition.

    Untreated or uncontrolled diabetes and high blood pressure can have a significant effect on the development of CKD over time, says Maruschak.

    According to the Centers for Disease Control and Prevention, more than 10 percent of the U.S. population has diabetes and over a third of adults have prediabetes, while about half of American adults age 20 and over have hypertension. These individuals are also at an increased risk of developing CKD.

    A healthy diet can help you prevent or manage conditions like diabetes and high blood pressure, in part by helping you to maintain a healthy weight, says Maruschak. In turn, this supports your kidney health.

    As part of a kidney-friendly diet, you may also need to limit certain foods to help prevent further kidney damage.

    What Are The Ways To Make A Kidney

    If you have diabetes along with kidney disease, you need to control your blood sugar to prevent more damage to your kidneys. A diabetic diet and a kidney-friendly diet share a lot of the same food items, but there are some important differences. There are some ways your kidney-friendly diet and diabetic diet can work together. Below are a few food items that are good for you, if youre diagnosed with both diabetes and kidney disease.

    • Fruits: Berries, papaya, cherries, apples and plums
    • Vegetables: Cauliflower, onions and spinach
    • Proteins: Lean meats , eggs and unsalted seafood
    • Carbohydrates: Whole-wheat breads, sandwich buns, unsalted crackers and pasta
    • Fluids: Water, clear soups and unsweetened tea
    • If you drink orange juice to treat low blood sugar, switch to kidney-friendly apple juice. It will provide the same blood sugar boost with a lot less potassium.
  • Late-stage disease: Your blood sugar levels get better with late-stage kidney disease, possibly because of changes in how the body uses insulin.
  • Dialysis: If you are on dialysis, your blood sugar can increase because the fluid used to filter your blood contains a high blood sugar level. Your doctor will monitor you closely and decide whether you will need insulin and other diabetes medicines.
  • Your doctor and/or dietician will help you to create a meal plan that helps you control your blood sugar level while limiting sodium, phosphorus, potassium and fluids in the body.

    Work With A Dietitian

    Making changes to your diet can be hard. If youre struggling to stick to a healthy diet, a registered dietitian can help you to develop a meal plan thats tailored to your individual needs.

    It can seem overwhelming to manage your diet, says Maruschak. An RD can help you to find foods that fit into your specific dietary requirements.

    What Not To Eat

    1. Apricots: Great for fiber but full of potassium, apricots are not ideal for those with kidney disease. The potassium content is even higher in dried apricots, so those need to be avoided entirely as part of any renal diet.

    2. Avocados: For a healthy individual, avocados are nutritious and beneficial, but for those with kidney problems, these fruits can be harmful. Avocados contain almost double the amount of potassium of bananas.

    3. Bananas: Full of potassium, bananas can reduce kidney efficiency. Tropical fruits in general are high in potassium, but pineapples prove to be more kidney-friendly.

    Keeping potassium levels low prevents hyperkalemia, a dangerous condition where your blood has too much potassium. When combined with renal failure, hyperkalemia can cause serious damage to your heart.

    4. Brown Rice: Brown rice contains more potassium and phosphorus than white rice, so it can place unnecessary strain on already damaged kidneys. With portion control, some brown rice can be consumed as part of a balanced renal diet.

    5. Canned Foods: Soups, as well as canned vegetables, are popular because of their convenience. The high sodium content is what gives these items a long shelf life but also makes them dangerous for impaired kidneys.
