ISAPP panel concludes that more evidence is needed to determine whether probiotics help restore an antibiotic-disrupted microbiota

By Dr. Mary Ellen Sanders PhD, Mary Ellen Sanders LLC, Colorado, USA, Dr. Hania Szajewska MD, Medical University of Warsaw, Poland, Prof. Karen Scott PhD, Rowett Institute, University of Aberdeen, Scotland, UK From the time scientists began to understand how antibiotics disrupt the gut microbiota, questions have been raised about whether probiotics could help recovery […]

Planning a Biotics Study? New Publication Recommends Adding Diet as a Variable

By Prof. Maria Marco PhD and Prof. Kevin Whelan PhD In studies on probiotics, prebiotics, and other biotics, the demonstrated health effect may depend on the personal characteristics and habits of the study participants. Take the following scenario: Person A and Person B consume the same prebiotic supplement. Person A typically eats a Mediterranean-style diet, […]

How do we know if a microbe is dead?

By Prof. Maria Marco PhD, University of California, Davis “Kills 99.9% of bacteria and viruses.” This percentage and others like it are frequently found on disinfectant labels. Ideally, the microbicidal effect of the product is sufficient to kill more than the numbers of the target pathogen or pathogens expected to be in the environment where […]

Can Probiotics Prevent Respiratory Tract Infections in Infants and Children?

By Prof. Hania Szajewska MD PhD, Medical University of Warsaw, Poland Imagine you are a primary care pediatrician practicing in an area where respiratory tract infections (RTIs) are particularly common during the winter months.

Prebiotics: Does Delivery Format Matter?

By Kelly S. Swanson, PhD, University of Illinois Urbana-Champaign, USA Prebiotics (1) have long been appreciated for their benefits to digestive function, immunity, energy balance, and metabolism. From a nutritionist’s perspective, the best way to consume dietary fibers and prebiotics is by eating a healthy diet comprising adequate amounts of whole grains, fruits, and vegetables. […]

Postbiotics: A global perspective on regulatory progress

By Dr. Gabriel Vinderola PhD, CONICET, National University of Litoral, Argentina While the conceptualisation of postbiotics varies among scientists, some recent actions may suggest that regulatory agencies around the world are starting to align with the ISAPP definition (Salminen et al. 2021), understanding postbiotics as preparations of inanimate microorganisms able to confer a health benefit. […]

Can we estimate prebiotic effects from short-chain fatty acid production?

By Prof. Kristin Verbeke PhD, KU Leuven Short-chain fatty acids (SCFA), primarily acetate, propionate and butyrate, are the most abundant anions in the large intestine. They are mainly produced from bacterial fermentation of undigested carbohydrates. Since SCFA were found to activate the orphan G-protein coupled receptors GPR-41 and 43 (renamed as free fatty acid receptor […]

Can prebiotics benefit brain health in older adults? ISAPP experts weigh in on a recent study

With increasing age and frailty come changes in the gut microbiota – leading scientists to ask whether targeting the gut microbiota using prebiotics could contribute to healthier aging. Of particular interest is whether prebiotics have the potential to affect brain health and cognitive performance in older adults. An intervention study led by researchers at King’s […]

Should bacteriophages be considered as a member of the biotic family?

By Prof. Colin Hill PhD DSc, University College Cork, Ireland ISAPP has provided consensus definitions for a number of biotics that confer a health benefit on the host. These include prebiotics, probiotics, synbiotics and postbiotics, but here I want to put forward an argument that bacteriophages (phages) could qualify as a new member of the […]

A guide to the new FDA Qualified Health Claim for yogurt

Fermented foods such as yogurt, kimchi, and fermented pickles have traditionally been associated with health benefits in countries around the world, but the science that backs these health benefits is relatively new. Amidst a growing number of scientific studies examining the health benefits of specific fermented foods, a new Food and Drug Administration (FDA) announcement […]

Statistical considerations for the design of randomized, controlled trials for probiotics and prebiotics

By Prof. Daniel Tancredi, UC Davis, USA The best evidence for the efficacy of probiotics or prebiotics generally comes from randomized controlled trials. The proper design of such trials should strive to use the available resources to achieve the most informative results for stakeholders, while properly accounting for the consequences of correct and incorrect decisions. […]

New paper outlines the value of studying probiotics in the small intestine

Even though the human digestive tract extends from the mouth down through the small and large intestines, the study of probiotics and their activities has tended to focus on the colon. While the colon (or perhaps more accurately its proxy, the faecal sample) is relatively accessible and easy to study, recently some researchers have argued […]
