Tag: Saltwater vs freshwater fish

Despite both being popular seafood choices, snapper and salmon are not the same fish; a major point of difference is that salmon is higher in fat and calories than lean snapper. They belong to different families and have distinct characteristics affecting everything from flavor to nutritional content.

According to the National Institutes of Health, while some shellfish naturally contain more sodium, many raw fish species are surprisingly low in this mineral. The perception that all seafood is excessively salty stems from a combination of natural factors, processing techniques, and cooking methods, all of which influence why is seafood so high in sodium.

Surprisingly, most raw fish are naturally low in sodium, with levels rarely exceeding 0.1 grams per 100 grams. The answer to the question "Does fish naturally contain salt?" lies in their sophisticated biological process called osmoregulation, which keeps their internal salt levels stable and far lower than their environment.
