Fast Food Fact: What You Think You Know About Fish and Sodium

Myth: Salt water fish have more salt (sodium) than fresh water fish.

Truth: Both types of fish are low salt choices. There is little difference in the sodium (salt) level between the two because the cells of living organisms have a narrow range of tolerance for salt. Salt water fish have gill cells that excrete excess salt back into the sea and freshwater fish use gill cells to take up salt from fresh water.
