Ferments Improve Our Microbiome

Fermented foods like yogurt, kimchi, sauerkraut and kombucha have long been dietary staples in many parts of the world. Indeed, for thousands of years, different cultures relied on fermentation to produce bread and cheese, preserve meats and vegetables, and enhance the flavors and textures of many foods.

Now scientists are discovering that fermented foods may have intriguing effects on our gut. Eating these foods may alter the makeup of the trillions of bacteria, viruses and fungi that inhabit our intestinal tracts, collectively known as the gut microbiome. They may also lead to lower levels of body-wide inflammation, which scientists increasingly link to a range of diseases tied to aging.

The latest findings come from a study published in the journal Cell that was carried out by researchers at Stanford University. They wanted to see what impact fermented foods might have on the gut and immune system, and how it might compare to eating a relatively healthy diet full of fruits, vegetables, beans, whole grains and other fiber-rich foods.
