Tuna and CKD: Phosphorus Data per 100 g

Short answer: Tuna contains 139 mg of Phosphorus per 100 g, which is 14% of the daily limit. This falls in the Low band, so portions matter if you are watching phosphorus.

About Tuna

Tuna belongs to the Meat & Protein category. 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

Tuna's phosphorus is the top contributor (14% of its limit). Source matters: animal phosphorus absorbs at 60-80%, additive phosphorus near 100% - the same number can mean very different real loads.

Phosphorus / Sodium / Potassium per 100 g

Practical tips

Practical tip: Boiling meat first and discarding the water removes some phosphorus and potassium; prefer low-phosphorus proteins like egg whites.
