Which foods have the most potassium?


can you provide a link to the data on potassium levels of various foods?

The new USDA National Nutrient Database for Standard Reference is now out! Our tax dollars hard at work to analyze the nutrient content of more than 8,000 foods. I’m so glad you asked this question, Charlene, because I’m surprised more don’t know about this incredible resource.

If you’re looking for the most concentrated sources of any particular nutrient in the new 2012 database, click here. Then scroll down to potassium and click on Potassium-Sorted By Nutrient Content and poof! A list of about a thousand foods ranked from the most concentrated source (2,675mg in each cup of concentrated tomato paste) down to zero in “foods” like lard and hard candies. You can also download the list alphabetically to make it easier to look up your favorite foods. And that’s just the beginning!

WARNING: browsing the Nutrient Database can be addictive for nutrition geeks–like me! (though if you were a true nutrition geek you’d already be sleeping with the entire database under your pillow :).

So the next time you see me do a video on fiber, for example, (like Relieving Yourself of Excess Estrogen) you can look up to see which foods have the most.

See Fat Burning Via Flavonoids and wonder where the heck you can find them? They’ve got the answer.

Amazed by Egg Industry Blind Spot or intrigued by Prevent Glaucoma and See 27 Miles Farther and want to know where to find those critical eyesight saving nutrients lutein and zeaxanthin? Look no further.

What foods have the most sugar? The most trans fats? The most cholesterol or the most vitamin C? It has it all!

A consumer friendly version available in PDF form of some of the most common nutrients in some of the most common foods can be downloaded here. And for more depth you can browse through individual reports on each of the 36 food groups.

    Do pickled beets have the same nutrient value as regular or cooked beets?

    • Judi Thompson

      Beets, Beets they’re good for your heart? And so many other body parts. Should you eat them raw, cooked, juiced, or pickled?

      In a side by side comparison of pickled beets/boiled/raw the nutrients all remained just about equal however, for pickled beets the sodium content almost quadruples and the sugar content more than doubles.

        Thanks. Having high blood pressure I completely forgot about the salt/sugar content.

  • Mcooks

    Some things that I have been told are very high in potassium are: coconut water, panela or natural cane sugar and molasses, however, I can’t find these on the chart. Any idea where they actually fall? Thank you very much.

  • Subtly Nutty

    I wonder what happened to the database? It only says “The service is unavailable.”

  • GTO

    haha oh Dr Greger! I’ll have to try that “database under my pillow” trick

    Do kale and other leaves retain nutrients when picked from the garden and frozen for smoothies in winter?

    • http://www.DonForresterMD.com/ Don Forrester MD

      Freezing food when it is fresh is an excellent way to retain nutrients.

    Thank you for all the work that you do. My husband and I became Vegans two months ago. Your videos are invaluable to us. Because my husband is a scientist he relies on facts. Whenever he quizzes me I refer him to your website. Thanks again Dr. Greger!!!

  • Roberta Peck

    When I tried to access the research sites, I found the gov closed them for lack of funding.

  • Derrek

    I get a yeast smell and don’t eat hardly any processed food. Just fruits and veggies. Should I lay off the fruit or what else would you recommend as I’m vegan and eat lots of veggies? I also have dandruff. Any advice?

    Also this is random, but is there any nutritional value difference in the different types of whole wheats like red, white, and etc?

  • Stephen Lucker Kelly

    Doesn’t this website have all the information on a handy search?

  • wkever

    Please help me understand the 4,700 mg per day standard for Potassium. I eat a
    whole-food plant-based diet, and log everything on a smartphone app.
    Potassium is one of the nutrients I have been tracking. I don’t think I
    have ever hit 4,700 mg of Potassium! It seems like an almost impossible
    target. It would take two pounds of baked potatoes – or a dozen bananas!

    Of course I could eat that many potatoes or bananas, but that would dominate my diet.

    I read up on the Institute of Medicine about the standard, and it
    seemed like they picked it because there seemed to be benefits to more
    Potassium and no ill effects to going that high. All well and good, but
    are we all supposed to actually strive to hit that number? We are told
    that we should not supplement Potassium, by Dr. Greger, Dr. Weil, and
    others. Canada has a standard of as I recall 1600mg.

    How much should I really be trying to get every day?

    Thanks for you help. I absolutely love the site!

      Hi wkever, Thanks for reposting your question. Hmmm a dozen bananas? I guess you’re right (I calculated about 11.3) if that is all you ate! What about beans? They are pretty high, 1 cup of black beans = 740mg. I feel like a balanced diet with plenty of plant-foods will give you 4700mg. Check out more of Dr. Greger’s links in the Answer section there is a way to find foods high in potassium if that is what you’re shooting for.


      • wkever

        I eat a whole can of beans nearly every day – that gives me about 1200mg for the 1.625 cups in the can. I would have to eat 4 whole cans of beans a day to get to the target.

        Could you provide an example food list for a day that reaches 4700mg of Potassium?

        I eat beans, greens, broccoli, and bananas every day and rarely come even close to the target.

        3 cups of raw spinach is 500mg. Sounds good, but it would take 28 cups of spinach to reach the target.

        It is discouraging when even the very best sources really are not all the dense.
