Health benefits and health claims of probiotics: bridging science and marketing

TLDR
An open dialogue between basic and clinical scientists, regulatory authorities, food and nutrition industry, and consumers could bridge the gap between science and marketing of probiotics.
Abstract
Health claims for probiotics are evaluated by the Panel on Dietetic Products, Nutrition and Allergies of the European Food Safety Authority. Despite a substantial amount of basic and clinical research on the beneficial effects of probiotics, all of the evaluated claim applications thus far have received a negative opinion. With the restrictions on the use of clinical endpoints, validated biomarkers for gut health and immune health in relation to reduction in disease risk are needed. Clear-cut criteria for design as well as evaluation of future studies are needed. An open dialogue between basic and clinical scientists, regulatory authorities, food and nutrition industry, and consumers could bridge the gap between science and marketing of probiotics.

Microorganisms with claimed probiotic properties: an overview of recent literature.

TL;DR: Caution in selecting and monitoring of probiotics for patients is needed and complete consideration of risk-benefit ratio before prescribing is recommended, as probiotic properties have been shown to be strain specific, accurate identification of particular strains is also very important.

The pros, cons, and many unknowns of probiotics

TL;DR: This Perspective highlights key advances, challenges and limitations in striving toward an unbiased interpretation of the large amount of data regarding over-the-counter probiotics, and proposes avenues to improve the quality of evidence, transparency, public awareness and regulation of their use.

Beneficial Metabolic Effects of a Probiotic via Butyrate-induced GLP-1 Hormone Secretion

TL;DR: It is demonstrated that the administration of a probiotic, VSL#3, prevented and treated obesity and diabetes in several mouse models and suggested that probiotics can modulate the gut microbiota-SCFA-hormone axis.

A microbial symbiosis factor prevents intestinal inflammatory disease

TL;DR: It is reported here that the prominent human symbiont Bacteroides fragilis protects animals from experimental colitis induced by Helicobacter hepaticus and that molecules of the bacterial microbiota can mediate the critical balance between health and disease.

Through Ageing, and Beyond: Gut Microbiota and Inflammatory Status in Seniors and Centenarians

TL;DR: Evidence is provided for the fact that the ageing process deeply affects the structure of the human gut microbiota, as well as its homeostasis with the host's immune system, because of its crucial role in the host physiology and health status.

Nonclassic Actions of Vitamin D

TL;DR: The nonclassic actions of vitamin D are cell specific and provide a number of potential new clinical applications for 1,25(OH)(2)D(3) and its analogs, however, the use ofitamin D metabolites and analogs for these applications remains limited by the classic actions of Vitamin D leading to hypercalcemia and hypercalcuria.

Host interactions of probiotic bacterial surface molecules: comparison with commensals and pathogens

TL;DR: This Review highlights the documented signalling interactions of the surface molecules of probiotic bacteria (such as long surface appendages, polysaccharides and lipoteichoic acids) with PRRs with respect to host pattern recognition receptors of the gastrointestinal mucosa.
