Foods highest in Potassium per 100 g (USDA)
The USDA food records with the most potassium per 100 g, with the share of the 4,700 mg Daily Value.
- Unit:
- mg per 100 g
- Daily Value:
- 4700 mg
- Datasets:
- Foundation Foods, SR Legacy and FNDDS
Potassium is the main positive ion inside cells and, with sodium, sets the electrical balance across cell membranes. USDA measures it as an element, so the value does not depend on which potassium salt the food contains. The Daily Value is 4,700 mg.
Cream of tartar (potassium bitartrate), dried herbs, tomato powder, molasses and dried fruit top the list, all of them concentrated or dry. Fresh vegetables, potatoes, beans, fish and dairy rank lower per 100 g but are the usual sources in a diet because they are eaten in hundreds of grams.
Top 100 foods by Potassium per 100 g
13,316 of 13,621 Normal catalog records report this nutrient (Foundation Foods: 369/397 · SR Legacy: 7,516/7,793 · FNDDS: 5,431/5,431). Records without a value are not ranked.
How to read this ranking
A baking ingredient or a spice at the top of the ranking is used in gram amounts. Cooking in water can move potassium out of vegetables into the cooking liquid, so raw and boiled records of the same food differ.
Values are USDA amounts per 100 g of edible portion, ordered as reported; this is information, not dietary advice. Methodology
