Scientists clarify what probiotics are and what they are not

A new scientific paper calls for strict adherence to the scientific definition, ensuring improper use of the term doesn't mislead consumers or limit advancements in the emerging field of microbiome science.

LOS ANGELES, March 14, 2019 /PRNewswire/ -- Today, Dr. Gregor Reid, the scientist who chaired the United Nations/World Health Organization Expert Panel that authored the definition of 'probiotics' in 20011, published a new paper in Frontiers in Microbiology: "Probiotics: Reiterating What They Are and What They Are Not", to reestablish and clarify the term.

Marketing and media misuse of the term 'probiotics', and even misunderstanding within the scientific community, has contributed to growing global skepticism about the legitimacy of microbial therapies and the associated probiotic applications to improve human health.

Reid authored this paper in an effort to ensure hype doesn't limit scientific and medical advancements. "Too many microbiome studies oversell limited findings or make broad generalizations that attribute the results of a single study on a single product across our entire field. Adherence by scientists, publications, and reporters to precise definitions and guidelines will ensure more accurate communications," said Reid. "Stewardship of the term 'probiotic' is critical to curb its misuse and misattribution and to protect the future of a field that has incredible promise."

Summary of Paper

Within the field of microbiome science, the rate of discovery of novel organisms with potentially therapeutic benefit is progressing rapidly and gaining prominence. More than ever, it is imperative that guidelines are followed to determine the validity of a probiotic. As indicated in the original FAO/WHO (2002) report1, there are certain expectations required to call an organism 'probiotic'. These have been further clarified in 20142, and must include:

Dr. Azza A. Gadir, PhD completed her postdoctoral training in the laboratory of Dr. Talal Chatila at Harvard Medical School/Boston Children's Hospital, where her published research focuses on the immunological mechanisms that underlie food allergy. She is specifically interested in understanding the role of the gut microbiome in conferring protection to diseases early in life. For this work, she is co-inventor of a patent for microbial consortia that can reduce and/or eliminate food allergy and has collaborated with industry partners to accelerate the discovery of microbiome-related immunotherapies for food allergy. She is Director of R+D at Seed.
