Who says eating healthily can’t be delightful? The yacon root offers a low glycemic index, low calories, and active weight-loss benefits. Its secret lies in a hard-to-pronounce ingredient called fructooligosaccharide (FOS). As a powerful prebiotic, FOS reaches the colon unmetabolized and nourishes the good bacteria in your system. In turn, a healthy gut microbiome has profound benefits on your health, waistline and emotional wellbeing.
