StageDietary potassium recommendationsComments
1
eGFR ≥ 90 mL per minute per 1.73 m2
Albuminuria < 30 mg per g		Same as general population; 3,510 mg per daySafe for potassium-rich foods (e.g., avocado, banana, spinach, leafy greens, potatoes, citrus juices, fish)
2
eGFR 60 to 89 mL per minute per 1.73 m2
Albuminuria < 30 mg per g		Same as general population;
3,510 mg per day		Safe for potassium-rich foods (e.g., avocado, banana, spinach, leafy greens, potatoes, citrus juices, fish)
3a
eGFR 45 to 59 mL per minute per 1.73 m2
Albuminuria < 30 mg per g
3b
eGFR 30 to 44 mL per minute per 1.73 m2
Albuminuria < 30 mg per g		Same as general population unless episodes of severe hyperkalemia occurRecommend fresh fruits and vegetables; limit milk and dairy products; avoid salt substitutes due to potassium chloride content; encourage a high-fiber diet*

eGFR 15 to 29 mL per minute per 1.73 m2
Any stage with A2 (albuminuria 30 to 300 mg per day) or A3 (albuminuria > 300 mg per day)		< 3,000 mg per day if hyperkalemia occurs frequentlyRecommend low-potassium foods (e.g., apples, berries, carrots, green beans, chicken, eggs, white grain breads, white rice); limit serving sizes; avoid salt substitutes and sea salt
