About this food

Fish sits in the Meat & Protein group. 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

Potassium is the highest of the three at 24%. With reduced kidney function, blood potassium can rise, so spread high-potassium foods across the day rather than in one large serving.

Practical tips
