Bananas. While their high fiber is great for your gut, the potassium-rich banana isn't so kind to your kidneys. Other potassium-rich fruits include oranges, cantaloupe, honeydew, and most tropical fruits (though watermelon and pineapple are generally safe.)
The Worst Foods for Your Kidneys
Bananas: Like avocados, bananas are high in potassium — in fact, they're famous for their potassium content. Though bananas are low in sodium, it is still best to avoid making them a daily staple if you're concerned about kidney health.
Pineapple, cranberries, red grapes, and apples are all kidney-friendly fruits with anti-inflammatory properties.
While plain water is the best drink for your kidneys, other fluids are perfectly acceptable, including coffee, green tea, low-potassium juices, and infused water. Avoid sweetened, carbonated beverages and coconut water.
Healthy options for kidney disease are protein, egg whites, fish, unsaturated fats, fresh or frozen fruits and vegetables, apple juice, grape and cranberry juice, light colored soda. The amount of protein intake per day varies depending on the stage of kidney disease.
Most people with early-stage CKD or a kidney transplant do not have to limit tomatoes because of potassium. If your laboratory results show higher levels of potassium, your doctor or kidney dietitian may talk with you about how much to eat. Potassium can be a concern depending on the amount you eat.
People with chronic kidney disease (CKD) are often concerned about eating tomatoes if they have been advised by their renal dietitian to follow a low potassium diet. However, in the right amount and served with the right foods, tomatoes can still be enjoyed safely.
Individuals with kidney disease should limit their intake of yogurt because it is high in potassium and phosphorus. Yogurt is high in protein, a nutrient that dialysis patients require. It's also high in calcium and vitamin D.
Broccoli is a medium potassium food, low in sodium and phosphorus, and suitable for all the following kidney conditions and treatments: Chronic Kidney Disease (CKD)
Beta-Carotene Benefits
Beta-carotene, the water-soluble form of vitamin A in carrots, helps the kidneys filter toxins out of the blood and prevent urinary tract infections, according to Dr. George D.
Phosphorus and Dairy Foods
Most dairy foods are very high in phosphorus. People with kidney disease should limit their daily intake of milk, yogurt, and cheese to ½ cup milk, or ½ cup yogurt or 1-ounce cheese.
Despite the nutritional benefits of potato tuber, patients with chronic kidney disease (CKD) should limit the consumption because of its high potassium content.
Greek yogurt requires careful consideration to be included in the meal plan for a person on dialysis. It is high in protein, phosphorus, and potassium. Yogurt can be found on more than one “to avoid” list for persons with chronic kidney disease (CKD).
Choose soy, almond, cashew, or rice milk for less phosphorus and less potassium than cow's milk. Avoid cow's milk substitutes that are "Enriched" or have the word phosphorus or "phos" in the ingredient list.
Take oats. Yes, they're higher in phosphorus, but a randomized study from Clinical Nutrition found that eating a bowl a day, or about half a cup of dry oats, had a net positive effect for people with CKD.
For healthy people, drinking low-fat cow's milk can have a protective effect on your kidneys. It can reduce your risk of chronic kidney disease and getting painful stones. However, for those diagnosed with kidney disease, the high calcium, phosphorus, and potassium levels in cow's milk can cause issues.
Beets and their juices contain Betaine which increases urine acidity, prevents build-up of struvite and calcium phosphate and reduces the chances of kidney stone formation. Other effective cleansing agents are coconut water, cucumber juice and cherries.
Water: Water is simply the best drink you can have! Water is a zero-calorie, perfectly hydrating, cheap drink. If you are in the earlier stages of kidney disease, choosing water most of the time to quench your thirst will keep your body and kidneys functioning well.
