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

Fish's sodium is the top contributor (351% of its limit). Sodium drives blood pressure and swelling, and most CKD patients limit it - watch hidden sodium in sauces and cured products.
