How much potassium is in cranberries and how does it fit stage 2?

Cranberries contains 80 mg potassium per 100g. At stage 2, your daily potassium budget is 2,800 mg — one standard serving (1 cup (~100g)) uses approximately 3% of that budget. This fits comfortably within the allowance.

What should stage 2 patients eat instead of cranberries?

Safer alternatives for stage 2 include: Apple, Grapes. Each is rated safe or caution at this stage with lower potassium or phosphorus per serving.

Serving Advice at Stage 2

Standard serving (1 cup (~100g)) is fine. For very high-volume foods, keep to one serving per day.

Stage 2 Diet Rules

Stage 2 (eGFR 60-89 with damage markers) still allows most foods in normal portions. Monitoring tightens and kidney-protective medications (SGLT2 inhibitors if albuminuric) enter the picture.

Potassium stays flexible but start learning the high-K foods — they'll matter later.
Prioritize sodium <2,000 mg/day; hypertension accelerates stage 2 progression.
Begin SGLT2 inhibitor discussion if albuminuric (UACR >200 mg/g) per KDIGO 2024.
Choose whole fruits over juices — juice concentrates potassium and sugar.
Watch portion sizes of nuts and seeds (high phosphorus).

No fluid restriction yet — drink to thirst, avoid dehydration. Protein target: 0.8 g/kg/day.
