Helpful Guidance

  • Portion size matters — potassium content increases quickly with larger servings.
  • Cooking methods, brands, and food preparation can affect potassium levels.
  • If you are on a potassium-restricted diet, review this list with your healthcare provider or registered dietitian.
  • Some high-potassium foods may still fit into your diet in smaller amounts or less frequent servings – ask your healthcare provider for specific recommendations.

*Potassium values are approximate averages and may vary by product, preparation method, and serving size. Check food labels for specific values. Individual dietary recommendations differ based on labs and medical history.
