About this food
Fish is a common member of Meat & Protein. Animal proteins tend to be higher in phosphorus, and animal phosphorus absorbs at 60-80% versus 30-50% for plants. Choosing low-phosphorus proteins such as egg whites or tofu, or controlling portions of red meat, is a common CKD approach. This helps when choosing similar foods.
Nutrient insight
Potassium is the highest of the three at 22%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.

Fiber0 gBeneficial for CKD (core plant-based nutrient)
How to eat it more safely: Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
Based on CKD stage 3-4 daily limits, Fish is rated Moderate - Potassium is the highest contributor at 22% of its limit. Ratings reflect public nutrition data only; individual cases should follow medical advice.
