Beans aren't inherently "bad," but those high in potassium and phosphorus, like lima beans, black beans, kidney beans, and white beans, may need to be limited if you have advanced kidney disease, especially if you're on dialysis, because failing kidneys struggle to remove these minerals, potentially leading to buildup. Canned beans also add significant sodium, so rinsing or choosing low-sodium options is key, and consulting a dietitian for personalized advice is crucial as plant-based diets offer benefits, but mineral intake needs careful management.
Low-moderate potassium bean options
There are a lot of legumes that are in the mid 300 mg potassium range that can easily fit into a low-moderate potassium diet too. You just might need to adjust the portion based on what else you consume. Some of these options are; kidney beans, pinto beans, and lentils.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
As you can see, the white bean potassium density is the highest out of all 24 bean varieties compared, while the potassium in chickpeas was the lowest. But don't let that get you down if you love garbanzo beans. Even though they're lowest on the ranking, garbanzo beans are still a great source of potassium!
Swiss chard, spinach, and beet greens. There are many green, leafy vegetables that people following a renal diet may need to avoid or limit due to their high potassium content. This is the case for Swiss chard, spinach, and beet greens. For example, a cup of raw Swiss chard contains 136 mg of potassium.
To support kidney health, focus on fruits like berries, apples, and red grapes; vegetables such as cauliflower, red peppers, and leafy greens; lean proteins like fish (salmon) and egg whites; and healthy fats from olive oil, using herbs and spices instead of salt for flavor, as a varied diet rich in whole foods helps filter toxins and manage inflammation.
Canned foods, some frozen foods, and most processed meats contain large amounts of salt. Snack foods such as chips and crackers are also high in salt. Table salt, some seasonings, ketchup, mustard, and certain sauces such as barbecue, soy, and teriyaki sauces are high in sodium.
Cannellini beans are the largest of the group and because of their traditional kidney shape, they can also be referred to as White Kidney Beans. Meatier than Navy or Great Northern beans, they have a nutty, earthy flavor and tender flesh, and are often used in Italian dishes like Minestrone.
Berries, including strawberries, cranberries, raspberries, and blueberries, are rich in anti-inflammatory and antioxidant properties. So, they prove to be a suitable option for promoting kidney health. By reducing the creatinine levels, they help prevent your kidneys from damage.
Potassium and phosphorus content varies with the fish variety–catfish, cod, orange roughy, sea bass and sole are among the lowest. Salmon contains higher amounts of potassium and phosphorus but can still be worked into a kidney diet by combining it with lower potassium sides and adjusting phosphorus binders if needed.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
Over-the-counter NSAIDS
They are not safe to use when you have kidney disease. Ibuprofen, such as Advil™ and Motrin™. Naproxen, such as Aleve™ and Naprosyn™. Aspirin for pain relief.
Urea is carried in the bloodstream to the kidneys, where it is removed along with water and other wastes in the form of urine. Other important functions of the kidneys include blood pressure regulation and the production of erythropoietin, which controls red blood cell production in the bone marrow.
Kidney-Supporting Vegetables
Here is a list of the most commonly eaten beans around the United States:
Beans are high in potassium, so you may be wondering how they fit into a kidney diet. Preparation is key. Soaking and cooking dried beans will help reduce potassium. To lower the potassium content, one cup of beans should be soaked in six cups of water for twelve hours and then cooked for 30 minutes using fresh water.
Here's a breakdown of the six most common supplements people with CKD may need to support kidney health.
Other ways to boost your kidney health are to: Avoid processed foods, which are high in salt. Eat plenty of fruits and veggies. Exercise routinely.
Apart from being used as a food flavoring, garlic also has many health benefits, including maintaining kidney health. Garlic is a source of manganese, vitamin B6, and vitamin C which are good for the body. Additionally, it also contains sulfur compounds that have anti-inflammatory properties.
High-Sodium Foods
Excess sodium can raise blood pressure and make your kidneys work harder, worsening kidney damage. Avoid these high-sodium culprits: Processed snacks like chips and crackers. Canned soups and vegetables packed in salt.
Control of phosphorus often is difficult for kidney failure patients. High-phosphorus foods to eliminate include: Beans (red, black, and white)
10 Common Habits That May Harm Your Kidneys
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
Low-phosphorus meat and poultry choices
Fresh or frozen red meats are better choices for a kidney diet if you are on dialysis. Avoid packaged red meats that have breading, pre-made marinades or sauces, which could contain unwanted phosphorus additives.
