Objective(s): Despite the nutritional benefits of potato tuber, patients with chronic kidney disease (CKD) should limit the consumption because of its high potassium content.
Sweet potatoes also contain vitamins and minerals, such as potassium, that may help balance the levels of sodium in the body and reduce its effect on the kidneys.
Potatoes and a Kidney-Friendly Diet
Nutritionally, potatoes are high in potassium, fiber, vitamin C and magnesium and a good source of carbohydrates. Potatoes can be part of a kidney-friendly diet, but be mindful of their potassium. One medium white potato contains 867 mg of potassium.
Potatoes are high in potassium (also know as “K”) which is a nutrient that must be limited when following a diet to manage kidney disease. People following a kidney-friendly diet can cut up and soak their potatoes in water to reduce their potassium content.
Results: Mean potassium content was highest in the purple Viking potato (448.1 6 60.5 mg [11.5 6 1.6 mEq]/100 g [values are mean 6 SD unless otherwise noted]), and lowest in the Idaho potato (295 6 15.7 mg [7.6 6 0.4 mEq]/100 g). All raw potatoes had a mean potassium content of about 300 mg (7.7 mEq)/100 g or greater.
For the most effective potassium removal, potatoes must be cut into small pieces, sliced thin or grated. If boiled at least 10 minutes in a large pot of water, potassium is reduced by at least half the original amount.
Pastas can have different nutritional content
If you have kidney disease, it's important to check the food label to make sure the pasta suits your nutritional needs. Certain pastas can have different nutritional content. For example, some pastas can have varying amounts of salt or sodium.
Summary: How to Include Potatoes in a Renal Diet
When it comes to low potassium potatoes, double boiling is a great way to help reduce the amount of potassium in your food. Double boiling can reduce potassium content in potatoes by approximately 50%.
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.
Most leafy green vegetables, including Swiss chard, spinach, and beet greens, are not recommended on a kidney diet due to their potassium content. Opt for lower potassium green vegetables such as green beans, asparagus, lettuce, and celery to limit your daily potassium intake.
Onions: Onions are a healthy food for people who have high creatinine levels and poor kidney function. They contain a substance known as prostaglandin, which naturally reduces blood viscosity and aids in the reduction of high blood pressure, thereby slowing the progression of kidney disease.
Rice is a great choice for the kidney diet—it provides energy and is low in minerals of concern for people with kidney disease or those on dialysis.
Fish and seafood
Cod, flounder, halibut, whitefish, catfish, salmon, tuna steaks and shrimp are good choices for your kidney diet.

Put limits on phosphorus- and potassium-laden foods.
To keep phosphorus and potassium levels at a minimum, cut out or reduce your intake of dairy products (milk, cheese, ice cream, creamy soups, chocolate), dried beans, peas, nuts and peanut butter.
I recommend whole grain, whole wheat or multigrain bread for people with kidney disease. Be careful to check the sodium in whatever bread you buy. Bread is a surprising source of salt! Historically, white bread was recommended because it has less phosphorus in it.
Candy not recommended on a kidney diet
Chocolate and nuts contain high amounts of phosphorus and potassium.
Although egg yolks are very nutritious, they contain high amounts of phosphorus, making egg whites a better choice for people following a renal diet. Egg whites provide a high quality, kidney-friendly source of protein.
