In plain language

A synthetic salt used to retain moisture and improve texture in processed seafood. It binds water molecules, keeping products plump and preventing them from drying out during processing or cooking. Generally recognised as safe at permitted levels. However, high phosphate intake — common in processed diets — is linked to kidney strain and cardiovascular issues, especially in people with kidney disease.
