8 Easy Ways to Cleanse Your Kidneys

The kidneys are amazing little organs. Each day, they process about 200 quarts of blood, getting rid of excess water and waste products, removing toxins and keeping the body functioning smoothly. If the kidneys are not able to remove toxins and waste from the body, they will build up in the body and hinder the normal function of kidneys, liver and other organs, resulting in exhaustion, stomach pain, headaches, water retention and other problems. Buildup of toxins and waste also may lead to kidney stones, a mass of crystals or unprocessed minerals which can grow to the size of a golf ball. Kidney stones affect 10-15 percent of American adults, but also may be found in children as young as five.

Kidney stones causes and symptoms

There are many causes of kidney stones, such as dehydration, excessively acidic urine, urinary tract infections, buildup of waste and toxins in the kidneys, among others. The symptoms of kidney stones include excessive lower back, abdominal or urinary tract pain which may be sharp, mild or excruciating, severe vomiting or feeling nauseated, persistent urge to pass urine, and constant chills or sweating. While the symptoms vary depending on the size of the stones, unceasing pain and discomfort on the sides is a good reason to see a urologist. Kidney stones are easily curable if diagnosed early.

Why you should cleanse your kidneys

There are several reasons why you should flush out toxins and waste from your body. For instance, cleansing your kidneys improves their function and reduces bloating. Likewise, cleansing your kidney improves your ability to process certain foods, absorb nutrients and convert food to energy, preventing fatigue. Flushing out waste and toxins prevents potential infection and reduce the risk for bladder problems. Similarly, cleansing the kidneys reduces the chances of having painful kidney stones, corrects hormonal imbalances and prevents skin breakouts such as acne, eczema and rashes.

Below are 8 easy ways to cleanse your kidneys

1. Apples cider vinegar (and apples) – Research suggests that apple cider vinegar might prevent kidney stones from developing because it helps flush out uric acid, a stone-contributing waste produce your kidneys make when breaking down certain foods. However, those with kidney disease should consult a doctor because their kidneys might not be able to process high levels of the vinegar’s acid. Apples, however, are a safe bet for a cleanse. They’re packed with fiber, antioxidants, and vitamin C, but low in potassium, phosphorous and sodium; a highly kidney-friendly mix.
2. Basil – Among many kidney-friendly herbs and spices the National Kidney Foundation suggests, basil is a gentle diuretic that increases urination, which helps the passage of stone-causing uric acid and other compounds from the kidneys. Basil also is light in potassium and phosphorous, important compounds that your kidneys process fine when healthy, but can be harder to break down if your kidneys are impaired. Other healthy seasonings include garlic, oregano, cinnamon, and ginger.
3. Beans (including kidney) – Beans are a plant-based protein rich in fiber, iron, and magnesium, but low in fat. They also contain high levels of vitamin B and minerals that support red blood cell formation, generate energy, and boost overall urinary function. Note that while beans carry phosphorous and potassium, the body doesn’t absorb these compounds from beans as easily as it does from animal sources, so there’s less buildup, making them kidney-friendly.
4. Cranberries – Cranberries carry compounds that can help stave off recurring urinary tract infections (UTIs), one of the most common bacterial infections (nearly 50% of women experience at least once). This is where your kidneys come in: If untreated or recurring, a UTI can travel to the kidneys and be severe. Cranberries also help reduce inflammation and keep the gut microbiome in balance, which makes your kidneys’ job easier.
5. Lemons and limes – While all citrus fruits serve as superfoods thanks to high levels of vitamin C and a cholesterol-managing fiber called pectin, lemons and limes edge out oranges for a kidney cleanse. First, lemons and limes carry much less potassium than oranges and nectarines, and second, lemons and limes contain citrate, which can prevent certain kidney stones from forming.
6. Pomegranate – The seeds and juice from the pomegranate hold significant amounts of vitamins K, E, and B6, as well as fiber, folate, and antioxidants, the latter of which are shown to reduce inflammation. While pomegranates are a source of potassium, they are low in phosphorous and salt. Talk to your doctor if you have kidney disease or are at risk.
7. Soothing teas – ­Certain teas may help cleanse your kidneys because they yield antioxidants that reduce the risk of kidney disease, a 2023 study finds. Green teas in particular contain antioxidants called catechins that make it harder for calcium to crystalize and form kidney stones. Suggested teas include green, hydrangea, and sambong.
8. Plant-based milks – Several milk alternatives hold smaller amounts of potassium and phosphorous than cow milk, so the kidneys can filter them with more ease. These include milks derived from oats, almonds, and soy. But note that soy, almond, and cashew milk are high-oxalate foods, making them risky for people who are prone to kidney stones.

Proper Cleansing Tips

If you want to undergo a kidney cleanse, we encourage you to learn more. As with any dietary changes, it’s a good idea to first talk to your doctor – especially if you are susceptible to kidney stones or have a history of kidney disease.

If you are prone to kidney issues, avoid certain foods – even super foods – until consulting a specialist. These foods include avocados, bananas, tomatoes, beet greens, dates, potatoes, certain dairy, and whole wheat bread.

Your kidneys are amazing little organs. When healthy, they serve as your body’s own natural filtering systems. You can help keep them healthy through the foods you eat, and by drinking enough non-sugary liquids to enable them to flush out the waste. When your kidneys are in at their filtering best, you’ll feel less strain all over.
