8 Fermented Foods to Boost Digestion and Health

Miso

Miso is a Japanese seasoning made by fermenting soybeans with salt and a type of fungus called koji. This seasoning frequently used in the preparation of miso soup, a Japanese dish typically served as breakfast. Miso is rich in proteins, B vitamins, calcium and iron. It is also rich in probiotic bacteria important for digestion.

A study involving nearly 22,000 women [8] conducted in Japan found a link between miso soup consumption and reduced breast cancer risk. Another study [9] of 40,000 people in 2007 established a link between higher miso soup consumption and a reduced risk of stroke in Japanese women.

Miso is good for heart health and can help in combating high blood pressure. A study [10] on middle-aged and older Japanese adults found that miso could help lower heart rate. It also did not increase blood pressure as other salty foods do. This finding was also reflected in an animal study [11] where miso soup consumption was found to help normalize blood pressure.
