Forbidden Foods in a High Potassium Diet

Potassium is an essential nutrient found in many foods, and is required to maintain heart and muscle function, fluid balance and proper tissue regulation and neural transmissions. But too much of a good thing is anything but good for many people. Individuals with certain kidney conditions, for example, have difficulty eliminating excess potassium acquired from foods they eat. The potassium builds up in their systems and causes a condition known as hyperkalemia.

  1. At Risk Conditions

    • People with chronic kidney stones, irregular heart rates, diabetes or other kidney conditions should limit their intake of potassium-rich foods in order to maintain proper levels in the bloodstream. Those who do not monitor their intakes run the risk of not only exacerbating their current conditions but developing new ones, such as impaired muscle function and even paralysis. Conditions such as infrequent menstrual cycles, joint and back pain, muscle spasms, anxiety, insomnia, chronic bladder infections and impotence may also be related to elevated potassium levels.

    Optimal Levels

    • The amount of potassium considered healthy for the general population is at least 4,700 mg per day, but those with certain health conditions should plan to consume much less: anywhere from 1,500-2,700 mg. Those concerned about the category they belong in should consult their doctors or nutritionists in order to determine if they are within their optimal levels.

    Foods to Avoid

    • If you're on a diet that requires limiting potassium levels, the following foods will be some you'll want to consume only in moderation or avoid altogether, depending on the severity of your condition:

      Figs
      Bran
      Dairy
      Peanut butter
      Pinto beans
      Cantaloupe
      Avocado
      Asparagus
      Apricots
      Bananas
      Kiwi
      Prunes/prune juice
      Collard greens
      Tomatoes
      Strawberries
      Chocolate

    Portions

    • Potassium tends to build up quickly in the system, so even eating foods with lower levels can be dangerous if you do not control portion sizes throughout the day. Together with your doctor or nutritionist, decide on an acceptable level of potassium to ingest, then break down this amount into proper serving sizes in order to ensure you're taking in safe amounts.

    Dining Out

    • Knowing which foods to choose when dining out can be daunting if you have a condition that requires reduced potassium intake, but it doesn't have to be. Simply choose steak and coleslaw instead of cream-based pastas and soups, club soda instead of cocktails made with fruit juice, or sorbet instead of ice cream. Once you become familiar with the types of foods high in potassium, it will become second nature to recognize them when combined in menu recipes.
