January 27, 2016 Researchers claim that the daily intake of β-glucan in yeast can reduce the risk of URTI (upper respiratory tract infection) in 66% of children.
This study further confirms the health promotion of yeast beta-glucan, especially for children.
Yeast beta-glucan is a natural carbohydrate extracted from the bacillus yeast cell wall through patented technology.The molecular structure of yeast β-glucan plays an important role in promoting immune cells and antibodies. These latest unpublished studies were conducted by randomized clinical trials in which recipients of DHA, prebiotic and yeast beta-glucan were fed to children of 3-4 years of age, and the results showed that the combination could promote the immune system.
Dr. Don Cox, senior vice president of research and development for yeast beta-glucan, said of the latest study, "Combined with previous studies, the results reveal the clinical evidence that yeast beta-glucan promotes children's health and enhances immunity."
The ingredients can be added to the soluble and insoluble powder, but also can be added to food and beverages, including fruit juice, smoothies, sports drinks and other functional drinks. Yeast beta-glucan has regulatory approval, including GRAS in the United States and new resources for food approval in China and Europe.
The research was funded by the US clinical research organization, H & J CRO International conducted research baker's yeast β- glucan reduce common childhood illness episodes capacity.
All the 174 children (12-48 months) with upper respiratory tract infection in the past three months were divided into three groups: treatment group 1 (35 mg yeast β-glucan per day), treatment group 2 (daily 75 mg yeast beta-glucan) and placebo group. The main indicator is the number of children who have not been infected with common infectious diseases during this period. The secondary survey is the number of infections during this period and the duration of illness.
A total of 156 children (73 men, 83 women) completed the study. Children who fed yeast beta-glucan during the study were healthier than the placebo group. During the 12-week study, 85% of children in the placebo group were infected with one or more infectious diseases. In contrast, 47% of the (treatment group 1) and 32% (treatment group 2) children were infected with infectious diseases, which was much less than the placebo group. The incidence and duration of URTI (upper respiratory tract infection) in the placebo group were higher than those in the two groups.
According to this study, the mechanism of yeast β-glucan is to enhance immune cells. Once the yeast beta-glucan is administered, the immune cells in the gastrointestinal tract are bound to it and transported to the various immune organs of the body. In immune organs, immune cells (macrophages) break down into smaller fragments. These small fragments bind to neutrophils through complement receptor 3 (CR3). Cox tells us, "By promoting the immune system, various immune cells can work more effectively and respond more quickly to pathogens before these pathogens lead to URTI (upper respiratory tract infection)."
The study was published at the American Society for Parenteral and Enteral Nutrition (ASPEN) Clinical Nutrition Week in January 2016.
