How much potassium is in fish tuna canned water and how does it fit stage 1?

Fish Tuna Canned Water contains 176 mg potassium per 100g. At stage 1, your daily potassium budget is 3,000 mg — one standard serving (100g cooked) uses approximately 6% of that budget. This fits comfortably within the allowance.

What should stage 1 patients eat instead of fish tuna canned water?

Safer alternatives for stage 1 include: Egg Whites, Tofu. Each is rated safe or caution at this stage with lower potassium or phosphorus per serving.

Is Fish Tuna Canned Water Safe for Stage 1?

Q: Can fish tuna canned water be eaten in stage 1 kidney disease?

Fish Tuna Canned Water is rated SAFE for stage 1 (eGFR ≥90 mL/min/1.73m²). Fish Tuna Canned Water is safe for stage 1 patients: potassium 176 mg/100g, phosphorus 137 mg/100g, and sodium 219 mg/100g all sit within the lenient thresholds for this stage. Normal portions (100g cooked) fit the daily 3,000 mg potassium budget comfortably.

GENERALLY LOWER CONCERN at this stage • eGFR ≥90 mL/min/1.73m²

Serving Advice at Stage 1

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

Stage 1 Diet Rules

Stage 1 means normal filtration (eGFR ≥90) with kidney damage markers (albuminuria, hematuria, or structural changes). Most foods are fine in normal portions — the goal is protecting the kidneys you have.

No strict potassium restriction at stage 1 unless serum potassium is elevated (>5.0 mEq/L).
Focus on sodium <2,000 mg/day to protect blood pressure — the #1 progression driver.
Avoid NSAIDs (diclofenac, ibuprofen) — the most common avoidable kidney insult.
Keep protein moderate (0.8 g/kg/day); avoid high-protein fad diets.
Most foods rated 'avoid' here are extreme potassium/sodium outliers — still skip coconut water, dates, and pickle.

No fluid restriction unless swelling or heart failure — drink to thirst. Protein target: 0.8 g/kg/day.
