At present, the novel coronavirus pneumonia (COVID-19) epidemic is raging around the world. The effect of chicory root extract on improving human immunity has attracted the attention of researchers.

Studies have shown that fructooligosaccharides and inulin in chicory root are naturally occurring prebiotics. Currently, oligofructose and inulin are the only scientifically proven plant-derived prebiotics. Such prebiotics can increase beneficial bifidobacteria in the gut, improve digestive health, and strengthen internal defenses in infants and children. Considering the health benefits, prebiotic oligosaccharides and inulin were initially added to infant and toddler formula and other infant food and beverage products.

The results of another study confirmed that the intake of prebiotics is also beneficial for children over 2 years old. The study was conducted for 6 months during the cold season when influenza is high. The results showed that 3- to 6-year-old kindergarten children who consumed a daily prebiotic fructooligosaccharide-inulin mixture extracted from chicory root (6 g/day) had stronger immunity compared to children who received a maltodextrin placebo force.

The prebiotic inulin and fructooligosaccharides in chicory root are special nutrients that can help people maintain a healthy immune system in many ways. These prebiotics not only increased the number of beneficial bifidobacteria in the gut of adults, but even reduced potential intestinal pathogens. Prebiotic chicory fiber has been shown to increase the activity of certain immune cells and help reduce diarrhea caused by pathogenic bacteria, so eating special prebiotic chicory root fiber is especially important for improving immune health. Currently, prebiotic chicory root extract is available in a variety of products including milk, yogurt, baked goods, cereals and snacks.
