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
Potassium at 22% is the main consideration. Concentrated forms such as juice and dried fruit absorb faster; whole foods are gentler.

Practical tips
A common practice is: Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
