About this food
About Fish: 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. As a Meat & Protein item, its role in a kidney diet depends mainly on mineral content.
Nutrient insight
On the phosphorus angle (34%), Fish belongs in the watch category. Pairing it with low-phosphorus sides like white rice or egg whites balances the meal.
Other nutrients
Protein19.7 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.
Based on CKD stage 3-4 daily limits, Fish is rated Higher risk - Phosphorus is the highest contributor at 34% of its limit. Ratings reflect public nutrition data only; individual cases should follow medical advice.
Why is Fish rated Higher risk?
Among phosphorus, sodium and potassium, Fish's Phosphorus is highest (337 mg, 34% of daily limit), falling in the >30% band - hence the Higher risk rating.
How much Phosphorus is in Fish?
Per 100 g, Fish provides Phosphorus 337 mg, compared with the CKD stage 3-4 limit of 1,000 mg (34%).
Is Fish safe on a low-potassium diet?
On a low-potassium plan, Fish exceeds the 300 mg reference, showing 344 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 more on Phosphorus (337 mg per 100 g) than the group average. Individual needs still decide what fits your plan.
