Long before modern science gave it a name, ancestral traditions understood that health begins in the gut. Hippocrates stated it over 2000 years ago: «All disease begins in the gut.» Dr. Bernard Jensen, a pioneer in intestinal health, dedicated his career to demonstrating that healing the body starts with healing the gut. Cultures worldwide — from Caucasian kefir to Japanese miso to European sauerkraut — have incorporated fermented foods as pillars of their traditional medicine.

Today, science is spectacularly proving them right. We host around 100 trillion microorganisms in our gut—an ecosystem so vast and influential that researchers now consider it a full-fledged organ.
