Foods Highest in Potassium

Quick answer

In our data the foods with the highest potassium per 100 g are Hearts of palm (1,810 mg), Gjetost cheese (1,410 mg), Cottonseed kernels (1,350 mg). This ranks the 779 foods that have a potassium value out of 790 relevant foods; dried foods and spices are listed separately because they are concentrated. Values come unchanged from USDA FoodData Central, UK CoFID and the Canadian Nutrient File. The top record is flagged as unusual; see Coverage and limitations below.

Coverage and limitations

• 779 of 790 relevant foods have a potassium value; 11 are not ranked because the source has none.
• Unusual record: Hearts of palm (raw). Checked 2026-11-05 against the USDA SR Legacy 2018-04 release: “Hearts of palm, raw” (FDC 167714, NDB 43392) gives 1,806 mg potassium per 100 g (shown rounded to 1,810 mg), about ten times the same database’s “Hearts of palm, canned” record (177 mg). The raw record also has 25.6 g carbohydrate and 69.5 g water per 100 g, against 4.6 g and 90.2 g for the canned record. The value is shown unchanged, as the source reports it; we could not confirm that it is typical of hearts of palm.
• All amounts are per 100 g of the food as described by the source record, in mg. Preparation is shown for every row and is never merged: the same food cooked differently is a separate record.
• Ranks are positions in this dataset only. Food composition varies by variety, season and processing.
• We do not show recommended intakes or health claims on this page. It is general information and not medical advice. Read more in About our data.

Questions about potassium in foods

Which food has the most potassium in this dataset?

Hearts of palm has the highest potassium value in our ranking: 1,810 mg per 100 g (USDA SR Legacy record 167714). This is the highest among the 779 foods with a value, not a statement about every food in existence. This record is flagged as unusual: see Coverage and limitations below.

What do the numbers mean?

Each value is the amount of potassium in mg per 100 g of the food as described by the source record, for the preparation shown on that row. The unit is mg.

How complete is the data for potassium?

779 of the 790 relevant foods in our data have a potassium value (99%). 11 have no usable value and are not ranked; a missing value is never treated as zero.

Why are dried foods and spices listed separately?

Dried foods, powders and spices are measured in a concentrated form, so they would outrank fresh foods per 100 g. We rank 99 such foods separately (the highest is Chervil at 4,740 mg).

Where do the values come from?

One source record is used per food, in a fixed order: USDA FoodData Central (Foundation Foods, then SR Legacy), then UK CoFID, then the Canadian Nutrient File. Values are never averaged. In this ranking: USDA SR Legacy (525 foods), UK CoFID (119 foods), USDA Foundation (89 foods), Canadian CNF (46 foods).
