About this food
For Meat & Protein, Fish is a typical example. 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.
Nutrient insight
On the phosphorus angle (20%), Fish belongs in the watch category. Pairing it with low-phosphorus sides like white rice or egg whites balances the meal.
Other nutrients
Protein17.7 gNot rated; needs attention at stage 4-5
Fiber0 gBeneficial for CKD (core plant-based nutrient)
A common practice is: Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
Fish scores Moderate on the phosphorus/sodium/potassium assessment, led by Phosphorus (20% of limit). This site presents data, not medical judgment.
Why is Fish rated Moderate?
The reason: Phosphorus (198 mg, 20%) is the most prominent of Fish's three minerals, at the 15-25% level, which maps to Moderate.
How much Phosphorus is in Fish?
Per 100 g, Fish provides Phosphorus 198 mg, compared with the CKD stage 3-4 limit of 1,000 mg (20%).
Is Fish safe on a low-potassium diet?
On a low-potassium plan, Fish falls below the 300 mg reference, showing 256 mg of Potassium per 100 g. Individual targets vary by CKD stage and lab results.
How does Fish compare to other meat & protein foods?
Within Meat & Protein, Fish ranks less on Phosphorus (198 mg per 100 g) than the group average. Individual needs still decide what fits your plan.
