Overview of Fish Sauce

Fish sauce is usually fermented for up to two years. During this time, the fishes release glutamate, an amino acid that’s used to make protein. As the fishes ferment, the salt also kills bacteria in the fish. 

Besides protein, fish sauce is also high in sodium, iodine, and vitamins A and D. It generally contains most of the ingredients you find in fishes. When shopping for fish sauce, it’s important to look for the best brands, as these will provide the most nutritional benefit.

Some manufacturers dilute their fish sauces with water, reducing the nutritional value and making them taste salty. Fish sauce that was shortly fermented will also taste unpleasantly fishy, which ruins most recipes.
