Top 3 Health Benefits of Fermented Foods

It’s commonly known that fermented foods contain probiotics that aid in the digestion of food, keep bad bacteria in control, and help support a healthy gut lining. Fermented foods also may have the potential to decrease markers of inflammation.


Health Benefits of Fermented Foods

#1 Decrease Markers of Inflammation

According to a study conducted by researchers at Stanford University, four types of immune cells showed less activation in the fermented-food group. The levels of 19 inflammatory proteins measured in blood samples also decreased. One of these proteins, interleukin 6, has been linked to conditions such as rheumatoid arthritis, Type 2 diabetes and chronic stress. 



In fact, frail study participants have higher levels of interleukin 6 than non frail, age-matched individuals.  Elevated serum IL-6 is positively associated with markers of physical frailty such as low walking speed, poor muscle strength, poor lower extremity performance, and anemia, even after adjustment for confounders. 



#2 Aids In Digestion

Maria Marco, a professor of food science and technology at UC Davis, and lead author of the 2017 review in Current Opinion in Biotechnology. Even at a cellular level, fermentation helps in this way. “I’m a proponent of including these foods, because first of all they are changing the way that the microbes have already started to break down the macromolecular structure of those foods for us,” Marco says. “And that helps with digestion.” 




Microbes used in fermentation do the type of work that normally occurs only after a person has eaten.” It’s almost like predigested food that we’re eating. Fermented foods tend to be a little easier to digest for us, because it’s already been started by the bacteria.”
