What Is A Low Potassium Diet?

A low potassium diet is a diet that contains less than 2,000 mg of potassium per day (2). For most people, this means eating less than six to eight servings of fruits and vegetables per day.

People with advanced kidney disease or those taking certain medications may need to limit their intake to even less, depending on their healthcare team’s recommendations.

Who Might Need To Follow A Low Potassium Diet?

Hyperkalemia is a condition in which there is too much potassium in the blood. The body needs a delicate balance of potassium to maintain normal cell function. When this balance is upset, it can cause problems like an irregular heartbeat or even heart failure (1).

For most people, the body can easily regulate potassium levels in the blood and hyperkalemia is not likely to happen. However, some illnesses, injuries, medications, or diseases disrupt the body’s ability to regulate potassium levels. If potassium levels in the blood become too high, it can be life-threatening. These people may need to follow a low potassium diet to help keep their potassium levels in check:

Kidney Problems

The kidneys play a major role in regulating potassium levels in the body. When they are not working properly, potassium can build up to dangerous levels. People with kidney problems are at a higher risk for hyperkalemia and may need to follow a low potassium diet (2).

Certain Medications

There are some medications that can cause hyperkalemia as a side effect.

These include certain blood pressure medications, water pills (diuretics), and potassium-sparing diuretics (2). If you take any of these medications, be sure to talk to your doctor about the risks of hyperkalemia and whether or not you need to follow a low potassium diet.

What Are The Risks Of Not Following A Low Potassium Diet?

If you do not follow a low potassium diet and your potassium levels become too high, it can lead to (1):

  • Muscle weakness
  • Fatigue
  • Paralysis
  • Abnormal heart rhythms
  • Cardiac arrest

You may need to be hospitalized if your potassium levels become dangerously high. Medications and intravenous fluids may be necessary to bring your levels back to normal.

Dos And Don’ts Of A Low Potassium Diet

Do:

  • Plan your meals in advance. This will help you make sure you are getting the right nutrients and not exceeding your potassium goals. 
  • Eat smaller meals more often throughout the day. This can help you avoid becoming too hungry and overeating. 
  • Read food labels carefully. Many processed foods are high in potassium and you may not realize it. 
  • Choose fresh fruits and vegetables when possible. Canned and frozen fruits and vegetables often have added sodium, which you are likely also recommended to limit on a low sodium diet. 
  • Cook at home as much as possible. This way you can control the amount of potassium in your food. 
  • Avoid salt substitutes. They often contain potassium and can increase your intake. 
  • Choose low or no-sodium versions of foods when possible. 
  • Limit your intake of dairy products. Dairy is high in potassium and should be limited on a low potassium diet. 
  • Choose restaurants that offer healthy options. Many restaurants now have menus with nutritional information listed.

Don’t:

  • Skip meals or snacks. This can make it more likely for you to overeat later in the day. 
  • Avoid fruits and vegetables altogether. While they are high in potassium, they also contain important vitamins and minerals. Just be sure to limit your intake and choose ones that are lower in potassium.  
  • Eat foods that are low in potassium without portion control. Just because a food is low in potassium does not mean you can eat as much as you want. 
  • Go on a crash diet. Rapid weight loss can lead to an increase in potassium levels. 
  • Eat too many processed foods or fast food. These foods are often high in sodium and potassium. 
  • Forget to take your medications. If you have a condition that requires you to take potassium-lowering medication, be sure to take it as prescribed.

Tips For Success When Eating Out On A Low Potassium Diet

Just because you’re on a  low potassium diet doesn’t mean you have to eat all of your meals at home. Here are some tips for eating out: 

Plan Ahead

Plan ahead and look up the menu online before you go. This way you can see what low potassium options are available. 

Avoid Higher Potassium Foods Beforehand

To have more choices when you’re at the restaurant, try avoiding higher potassium foods earlier in the day. This way you’ll have more allowance to enjoy a higher potassium meal later on.

Skip The Salad Bar

Salad bars can be tempting, but they are often high in potassium due to all of the toppings. If the restaurant has a salad bar, it’s best to avoid it. 

Share Your Food

If you’re worried about portion sizes, try sharing your food with a friend or family member. This way you can still enjoy a restaurant meal without overeating. 

Request No Added Salt

When ordering your food, request that no additional salt be added. This will help reduce your sodium intake.

Make Special Requests

Don’t be afraid to make special requests. Most restaurants are happy to accommodate dietary restrictions. 

Ask For Your Food To Be Prepared A Certain Way

If there is an option on the menu that sounds good but is high in potassium, ask if it can be prepared a different way.

Skip The Sauce

Many sauces and dressings are high in sodium and potassium. Ask for them to be prepared on the side so you can control how much you eat. 

Watch Your Portion Size

Even if a food is relatively low in potassium, eating too much of it can still cause your potassium levels to rise. Be sure to control your portion size and only eat until you are full.

Eating out on a low potassium diet doesn’t have to be difficult. With a little planning, you can enjoy a meal at your favorite restaurant without worrying about your potassium levels.

Potassium Content In Ethnic Foods

It can be difficult to find low potassium foods when eating at a restaurant. However, there are still some options available.

Here is the general potassium content of some common ethnic cuisines:

Chinese Food

While  Chinese food can be high in sodium, there are still some low potassium options available. Try lower-potassium vegetables such as snow peas, string beans, water chestnuts, bean sprouts, or bok choy

Mexican Food

Mexican food is often high in potassium due to the beans and vegetables used in many dishes. Avoid salsa verde, guacamole refried beans, and black beans. Opt for lower-potassium options such as flour tortillas, chicken, or shrimp.

Italian Food

Many Italian dishes are high in potassium due to the tomato sauce used in them. Avoid pasta with marinara sauce, spaghetti with meatballs, and lasagna. Opt for plain pasta, white pizza, or chicken parmesan. 

Soul Food

Unfortunately, many soul food dishes are high in potassium.

To lower the potassium content, avoid foods such as sweet potatoes, collard greens, and black-eyed peas. Opt for white rice, fried chicken without the skin, or green beans. 

The Bottom Line

A low potassium diet is essential for some people with kidney disease. However, following this diet doesn’t mean you have to give up eating out at your favorite restaurants. With a little planning, you can still enjoy a meal away from home.
