It also contains smaller amounts of B vitamins, calcium, iron, magnesium, selenium and phosphorus, and is a source of choline. Interestingly, the varieties made from soybeans are considered to be sources of complete protein because they contain all the essential amino acids needed for human health (http://nutritiondata.self.com/facts/legumes-and-legume-products/4379/2).

The fermentation process used to produce miso makes it easier for the body to absorb the nutrients it contains (https://www.ncbi.nlm.nih.gov/pubmed/15671685). The fermentation process also promotes the growth of probiotics, beneficial bacteria that provide a wide array of health benefits. A. oryzae is the main probiotic strain found in miso (https://www.ncbi.nlm.nih.gov/pubmed/18072744)

Miso is also very salty so if you’re watching your salt intake, check with your medical doctor before adding large quantities to your diet. You should not need to add additional salt to dishes that include miso.

Your gut is home to trillions of bacteria.

Miso fermentation helps improve the body’s ability to digest and absorb foods. The condiment also contains probiotics that can promote gut health and digestion.

Miso is also rich in antioxidants, which may help guard your body’s cells against damage from free radicals, a type of cell damage linked to cancer (https://www.ncbi.nlm.nih.gov/pubmed/1333523).

Regular miso consumption may reduce the risk of certain types of cancer. However, more research is needed.

Information found on healthline.com says miso may strengthen your immune system. Miso contains nutrients that may help your immune system function optimally. For instance, the probiotics in miso may help strengthen your gut flora, in turn boosting immunity and reducing the growth of harmful bacteria (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5050011/). Moreover, a probiotic-rich diet may help reduce your risk of being sick and help you recover faster from infections, such as the common cold (https://www.ncbi.nlm.nih.gov/pubmed/25430686).

In addition, regularly consuming probiotic-rich foods like miso may reduce the need for infection-fighting antibiotics by up to 33% (https://www.ncbi.nlm.nih.gov/pubmed/21901706).

 Miso’s rich probiotic content may boost your immune system and help ward off infections. That said, more studies are needed before strong conclusions can be made.

  • May promote heart health: Miso soup may reduce the risk of death from heart disease. However, the protective effects appear to be small and may be specific to Japanese women (https://www.ncbi.nlm.nih.gov/pubmed/18025534).
  • May reduce cholesterol levels: Animal studies show that miso may help reduce levels of “bad” LDL cholesterol in the blood (Research Gate https://www.researchgate.net/publication/276932086).
  • May reduce blood pressure: Miso appears to reduce blood pressure in animals. However, results in humans remain divided (https://www.ncbi.nlm.nih.gov/pubmed/22261579).
  • May protect against type 2 diabetes: Some studies show that fermented soy products such as miso may help delay the progression of type 2 diabetes. However, not all studies agree (https://www.ncbi.nlm.nih.gov/pubmed/20116654).
  • May promote brain health: Probiotic-rich foods such as miso may benefit brain health by helping improve memory and reducing symptoms of anxiety, stress, depression, autism and obsessive-compulsive disorder (OCD) (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5216880/)

 Miso consumption is indirectly linked to a variety of additional health benefits.
