Gut health plays a crucial role in overall well-being, influencing everything from digestion and immunity to mental health. The gut microbiome—the collection of microorganisms living in the digestive tract—requires a healthy balance of beneficial bacteria to function properly. Fermented foods are one of the best natural ways to support a healthy gut. These foods undergo a process of lacto-fermentation, in which natural bacteria feed on sugars and starches, producing lactic acid. This process creates beneficial probiotics, which promote the growth of healthy bacteria in the gut and support digestive health.
In this article, we will explore the 16 best fermented foods for people with gut health concerns, highlighting their benefits, how they promote a healthy microbiome, and the best ways to incorporate them into your diet.
