Organ meats, such as brain and liver, are excellent sources of highly absorbable phosphorus.
One 3-oz (85-g) serving of pan-fried cow’s brain contains almost 26% of the DV.
Chicken liver, which is often used to make the French delicacy pâté, contains 30% of the DV per 3 oz (85 g).
Organ meats are also rich in other essential nutrients, such as vitamin A, vitamin B12, iron, and trace minerals. They can make a delicious and nutritious addition to your diet.
SUMMARYOrgan meats are incredibly nutrient-dense, and contain large amounts of phosphorus and other vitamins and minerals. Brain and liver both contain 26%–30% of the DV per 3-oz (85-g) serving.
4. Seafood

Many types of seafood are good sources of phosphorus.
Cuttlefish, a mollusk related to squid and octopus, is one of the richest sources, supplying 39% of the DV in each 3-oz (85-g) cooked serving.

Some of these foods, like salmon, sardines, and mackerel, are also good sources of the anti-inflammatory omega-3 fatty acids that may protect against cancer, heart disease, and other chronic illnesses.
