Follow a clinician’s guidance based on your lab results and kidney function
Limit high-potassium foods (especially if you have kidney disease or recurrent high potassium)
Avoid salt substitutes that contain potassium chloride
Reduce or avoid potassium-rich foods such as:
Potatoes, sweet potatoes, and plantains
Tomatoes and tomato products
Spinach and other leafy greens
Beans, lentils, and chickpeas
Nuts and nut butters
Dried fruits (dates, raisins, prunes)

Bananas, oranges, cantaloupe, and other high-potassium fruits

Cabbage, cauliflower, green beans, lettuce (as advised)
Rice, pasta, white bread, and oatmeal (portion-controlled)
Applesauce (unsweetened), cranberry juice (unsweetened) in moderation
Use potassium-lowering cooking methods for vegetables (only if appropriate for your diet):
Leach vegetables by soaking and boiling, then discarding the water
Watch portion sizes and avoid “healthy” potassium supplements and electrolyte drinks
Review all medications and supplements with a clinician, including:
ACE inhibitors (e.g., lisinopril)
ARBs (e.g., losartan)
Potassium-sparing diuretics (e.g., spironolactone, eplerenone, amiloride, triamterene)
NSAIDs (e.g., ibuprofen, naproxen) if advised against for you
Potassium supplements
Seek urgent care if you have symptoms such as palpitations, weakness, shortness of breath, or fainting
If potassium is very high or symptomatic, get immediate medical treatment (e.g., emergency therapies prescribed by clinicians)
If you have chronic kidney disease, follow a renal diet plan and schedule regular lab monitoring
