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 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.
