31 Oct 2023 --- International researchers determined that intake of the prebiotic dietary fiber oligofructose and a combination of the fiber with the human milk oligosaccharide (HMO) 2’fucosyllactose may improve mood in healthy adults with mild to moderate feelings of anxiety and depression. The consumption of the prebiotic fiber — Beneo’s Orafti produced from chicory root — promoted an increase in Bifidobacteria in the gut. “The study shows ‘the gut-brain axis at work,’ and its results are great news for companies such as Beneo, providing scientifically proven prebiotics that have been shown to deliver effective results to meet the growing market need for dietary-based mood improvement,” Dr. Stephan Theis, co-author of the study and head of nutrition science at Beneo, tells Nutrition Insight.
