High-potassium foods to avoid by people living with kidney disease

PEOPLE with chronic kidney disease need to limit the amount of potassium they consume because their kidneys cannot process potassium properly, causing it to build up in the blood.

Medications used to treat kidney disease can also raise potassium levels. One the best ways to manage potassium levels is by making dietary changes. This may mean avoiding high-potassium foods and replacing them with low-potassium alternatives.

According to a report published in Medical News Today, people with chronic kidney disease or CKD should avoid or limit foods that are high in potassium.

High-potassium levels can cause serious symptoms, including an irregular heartbeat and muscle cramping. Low-potassium levels can cause muscles to become weak.

A doctor or dietitian can help explain the right amount of potassium to consume for each person's unique situation.

Some high-potassium foods that people with CKD should limit or avoid include: nuts; beans and legumes; potatoes; bananas; most dairy products; avocados; salty foods; fast foods; processed meats, such as luncheon meats and hot dogs; bran and whole grains; spinach; cantaloupe and honeydew; tomatoes; and vegetable juices.

Dietary restrictions can help prevent further damage to the kidneys in those with CKD.

Apples are a popular low-potassium snack. Low-potassium foods are a safer option for people with CKD. According to the American Kidney Foundation, a potassium-restricted diet allows for 2,000 milligrams of potassium daily.
