Probiotics are “live microorganisms that, when administered in adequate amounts, confer a health benefit on the host”. These microorganisms, which consist mainly of bacteria but also include yeasts, are naturally present in fermented foods, may be added to other food products, and are available as dietary supplements. The potential health benefits of probiotics are the focus of a great deal of scientific research. This section focuses on research on the use of probiotics to prevent or treat six health conditions: atopic dermatitis, pediatric acute infectious diarrhea, antibiotic-associated diarrhea, irritable bowel syndrome, hypercholesterolemia, and obesity.
