You can help prevent hyperkalemia by limiting the amount of potassium you take in. Ask your doctor or dietitian to tell you how much potassium you should have each day to prevent hyperkalemia. Once you have a goal, you can plan your meals to make sure you are getting the right amount of potassium every day.
To achieve your potassium goal, you will need to know how much potassium is in your foods and drinks. Packaged foods must have nutrition labels, but potassium is not always listed on the label. If you don’t see potassium listed on the nutrition label, check the list of ingredients on the package. If the word potassium or an abbreviation for potassium (K, KCl or K+) is listed, there is potassium in the food.
Fresh fruits, vegetables, meats and dairy products often do not have labels. Ask your dietitian for a list of high potassium foods and lower potassium options.
Plan ahead if you know you will be eating a meal that is high in potassium. For example, if you are going out for dinner later and you know your meal will be high in potassium, or you know that it will be hard to measure how much potassium is in your meal, plan to eat meals that are low in potassium for breakfast and lunch.
