About this food

Fish (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 is the same lens used for similar items.

Nutrient insight

Phosphorus at 26% is the highest item. Additive phosphorus in processed foods absorbs best; naturally occurring phosphorus is more controllable.
