BACKGROUND: Human milk oligosaccharide (HMO) is a third most abundant component in breast milk. HMOs are molecules naturally tailored to the need of an infant. They protect infants from diseases, foster healthy gastrointestinal systems, reinforce fledgling immune function, and promote early brain development. Supplement HMOs to infant formula, which lack this critical element, would substantially improve the function of formula. Overwhelming evidence also indicate that HMOs can be used for the treatment of arthritis and related autoimmune disease, and inhibition of bacteria adhesion or as potential prebiotics...
