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.

I often recommend limiting high potassium foods to a set number of servings per week, depending on how high potassium levels are and how much my patient was eating before. Some patients can tolerate one high potassium food per day, others can only handle one serving per week. Your dietitian can help you figure out how much is right for you.

Foods To Eat Or Avoid If You Have Kidney Disease

Chronic kidney disease can be either long-term or chronic, but it is possible to live a normal life with the disease. One of the best things you can do to help manage your disease and keep it from progressing is to eat a healthy, balanced diet.

For those with chronic kidney disease, a low-protein diet is recommended, but for someone on dialysis, a high-protein diet is best. Depending on your individual needs, your physician may also recommend limiting additional fluids, minerals or electrolytes. Here are 10 foods to eat or avoid if you have kidney disease:

Foods to Eat

Foods to Avoid

Kidney disease or not, what you eat and drink affects your health. Maintaining a healthy weight and eating a balanced diet is key to controlling your blood pressure and blood sugar. High blood pressure and diabetes are two of the leading causes of kidney disease, as well as many other conditions including heart disease, heart attacks and stroke.

A kidney-healthy diet isnt so much about eliminating a ton of foods entirely, but more about portion control and finding the right balance of protein, fats and carbohydrates to ensure you are consuming enough calories and nutrients.

The Best Foods For Kidney Health

Kidneys are small organs located underneath the rib cage, on each side of the spine. They are responsible for filtering waste out of the blood and excreting it out of the body through urine. Kidneys also balance the bodys fluid and electrolyte levels and play a significant role in overall health. Some foods may boost the performance of the kidneys, while others may place stress on them and cause damage. Eating foods rich in certain vitamins and nutrients may help the kidneys function properly and prevent damage to them. However, some foods that generally help support healthy kidneys may not be suitable for people who have an existing kidney disease. Check with your doctor or dietitian if you have an existing condition to find out which foods are best for you.

1. Dark leafy greens

Dark leafy green vegetables such as kale, spinach, chard, and collard greens are loaded with vitamins A and C, calcium, and many other important minerals. Kale also is a significant source of carotenoids, flavonoids, and vitamin K. Spinach is high in vitamins A, C, K, and folate. The beta-carotene found in spinach is important for boosting your immune system and a good source of magnesium. Try replacing that nutritionally challenged iceberg lettuce with some dark leafy greens.

2. Berries

3. Cranberries

4. Sweet potatoes

5. Olive oil

6. Fatty fish

7. Cabbage

Limit Shellfish And Meat

Research has found that a toxin called domoic acid in shellfish and some fish that eat algae can harm kidneys in mice. People are not mice. But, the really troubling finding was that very tiny levels of the toxin could harm kidneys. Shellfish also have high levels of purines, which can be a problem if you have gout. So, it may be wise to cut back on shellfish if you eat it a lot.

Dairy and Potassium

Dairy is moderately high in potassium. Eating too much can contribute excess potassium. Milk, yogurt and cheese are all moderately high. Be careful to avoid large amounts of these foods. For most of my patients, I recommend no more than 1 serving of dairy per day . Rice milk can be a great low potassium substitute for cows milk.

Hidden Potassium

Extra potassium has found its way into our food supply as part of food additives in processed foods. One study found that meat and poultry products labeled as low-sodium actually contained 44% more potassium than regular versions as a result of potassium additives9. The potassium is added in an effort to make the food more heart-healthy. However, this extra potassium could be harmful for kidney patients.

As of January 2020, food manufacturers are required to start adding potassium to food labels, so this will help us figure out how much potassium is in our food. However, I still recommend reading the ingredients on Nutrition Facts labels to be safe. Look for the word potassium in ANY part of a word in the ingredients.

While leafy vegetables shrink to a smaller serving size when cooked, the potassium content remains the same.

For example, one-half cup of raw spinach will shrink to about 1 tablespoon when cooked. Thus, eating one-half cup of cooked spinach will contain a much higher amount of potassium than one-half cup of raw spinach.

Raw Swiss chard, spinach, and beet greens are preferable to cooked greens to avoid too much potassium.

However, moderate your intake of these foods, as theyre also high in oxalates. Among sensitive individuals, oxalates can increase the risk of kidney stones (
