Miso soup is celebrated for its health benefits but contains high sodium levels that may concern those on a low-salt diet.
Miso soup’s health benefits and sodium content
Miso soup is a traditional Japanese dish often associated with health benefits, particularly for digestion and immunity. It is commonly served in Japan and in health-focused cafes around the world.High sodium levels in miso paste
The soup's base, miso paste, is made by fermenting soybeans with salt and a mold called koji. This process gives it a rich, savory flavor but also makes it high in sodium. A single spoonful can contain a significant portion of the daily recommended sodium intake.Sodium recommendations and health considerations
The American Heart Association advises a daily sodium limit of 2,300 mg, with an ideal goal of 1,500 mg. A 17-gram serving of miso paste contains about 634 mg of sodium, which is a notable portion of these limits for individuals monitoring their salt intake.Miso paste’s fermentation process
Miso paste is created through a fermentation process that uses the fungus Aspergillus oryzae, also known as koji. This process not only gives miso its distinctive umami flavor but also contributes to its nutritional profile.Miso’s role as a condiment and digestive aid
Because of its strong flavor, miso paste is typically used in small amounts, acting more like a condiment than a main ingredient. Some studies suggest that fermented foods like miso may support digestion and reduce discomforts such as gas.
