Chicory fiber may support digestive health in adults, children

Two scientific studies published in the International Journal of Food Sciences and Nutrition suggest that prebiotic chicory root inulin may support digestive health by improving bowel regularity and softening stools.

The first study was a randomized, double-blind, placebo-controlled, cross-over design trial of 44 healthy, slightly constipated subjects (self-reported constipation defined as 2–3 stools per week). The participants were supplemented with 4 g of chicory root fiber (Orafti inulin by Beneo) three times a day or a placebo (maltodextrin). The supplements were delivered in a drink form that was consumed together with breakfast, lunch, and dinner over a four-week period and after a two-week run-in phase.

The researchers found that the prebiotic chicory inulin significantly improved stool frequency per week without resulting in gastrointestinal discomfort. Chicory root inulin also contributed to improved overall wellbeing and satisfaction, evaluated by a validated quality of life questionnaire for constipated people.

The second study was a randomized, double-blind, placebo-controlled parallel group design focused on children, aged 2–5. The children received 2 g of Beneo’s Orafti inulin and oligofructose twice daily or a placebo (maltodextrin), incorporated into yogurt or fresh cheese, for a six-week period. The researchers found that the chicory root fibers softened the stools of the constipated children and were as well tolerated as the fully digestible placebo.

The researchers suspect that the physiological mechanisms underlying this digestive support by chicory root fibers are related to their prebiotic effect. The fibers selectively stimulate the growth of bacteria promoting saccharolytic fermentation, in particular Bifidobacteria and Lactobacilli.
