Low-potassium foods

642 USDA reference foods have under 200 mg per portion, the cut the National Kidney Foundation uses for low-potassium foods. The lowest, snacks, soy chips or crisps, salted, has 2.0 mg in 1 oz.

Updated · By · data: USDA FoodData Central, April 30, 2026 release · how the figures are checked

With chronic kidney disease the kidneys may not clear potassium, and blood levels can become too high; NIDDK advises working with your health care team on potassium, and notes that some packaged foods use potassium chloride in place of salt (niddk.nih.gov).

How much potassium a day, by age and sex

The label's Daily Value is one figure for everyone; the Dietary Guidelines set the goal by age and sex (AI): 2,600 mg for women and 3,400 mg for men aged 19 to 30.

Per 100 g, the list starts elsewhere

The portion ranking compares everyday foods at the portion FDA's reference amounts describe (USDA's NLEA serving where it lists one). Seasonings, sauces, powders, dried and concentrated forms, raw meat and fish, uncooked grains and dry beans, restaurant items and foods without a household measure near that portion are ranked per 100 g only: nobody eats a cup of dried thyme. Per 100 g, these lead:
