Intestinal microbiota is comprised of more than 100 trillion typically non-pathogenic commensal microorganisms, and it is
estimated that more than 90% of the DNA in a human body is actually microbial DNA[12e14].
Intestinal microbiota aids in the digestion, absorption and metabolism of nutrients[15,16].
However, more recently, microbiota was reported to contribute to increased risk of cardiovascular disease, obesity, insulin resistance, type II diabetes and asthma[17e22].
