Completing our series on the role of biotics in animal health, we are highlighting Episode 22 from our archives. In this episode, Prof. Kelly Swanson PhD from University of Illinois at Urbana-Champaign discusses the role of biotics in animal and human nutrition. He reviews the criteria for prebiotics and synbiotics, then discusses how we gain knowledge about nutrition and the role of biotics in animals compared to humans.

Key topics from this episode:

  • A good argument can be made that biotics are essential for our diet; they are beneficial even if efficacy is sometimes difficult to prove.
  • Nutrients have an impact on the host’s health and simultaneously on the host-associated microbes.
  • Health benefits are essential to the FDA definition of fiber.
  • Antibiotics’ effect on the microbiota: short-term effects may be minor, but we still don’t know the long-term effects.
  • The synbiotics definition, criteria for products to meet this definition, and the health outcomes from using these biotic substances.
  • The difference between complementary and synergistic synbiotics.
  • When studying biotics in companion animals (cats and dogs), can results from one host be extrapolated to another host? Final studies should be in the target host.
  • Biotics are important in veterinary medicine and a popular topic of study.
  • Predictions about the future of nutrition science as informed by the microbiome.

2023 in Review: Highlights in the Field of Biotic Science

/in ISAPP Science Blog /by KC

By Kristina Campbell, Prof. Colin Hill PhD, Prof. Sarah Lebeer PhD, Prof. Maria Marco PhD, Prof. Dan Merenstein MD, Prof. Hania Szajewska MD PhD, Prof. Dan Tancredi PhD, Prof. Kristin Verbeke PhD, Dr. Gabriel Vinderola PhD, Dr. Anisha Wijeyesekera PhD, and Marla Cunningham

Biotic science is an active field, with over 6,600 scientific papers published in the past year. The scientific work that emerged in 2023 covered many diverse areas – from probiotic mechanisms of action to the use of biotics in clinical populations. In parallel with the scientific advancements, consumer interest in gut health and biotics is at an all-time high. A recent survey showed that 67 percent of consumers are familiar with the concept of probiotics and 51 percent of those who consume probiotics do so with the aim of supporting gut health.

Several ISAPP-affiliated experts took the time to reflect on 2023 and identify the most important directions in the fields of probiotics, prebiotics, synbiotics, postbiotics, and fermented foods. Below are these experts’ picks for the top developments in biotic science and application during the past year.

Increased recognition of biotics as a category

After ISAPP’s publication of the recent synbiotics and postbiotics definitions in 2020-2021, board members and others began referring to probiotics, prebiotics, synbiotics, and postbiotics collectively as “biotics”. 2023 has seen the term being used more widely (for example, in article headlines and communications from major organizations) to refer to these substances as a broad group.

Steps forward and steps back in the regulation of live microbial interventions

The actions of regulators have a profound impact on how biotic science is applied and how products can reach consumers. On the positive side, 2023 heralded the regulatory approval of two live microbial drug products for recurrent C. difficile infection by the US Food and Drug Administration (FDA). Both products are derived from fecal samples, but one is delivered to the patient gastrointestinal (GI) tract by enema, and the other is delivered orally.

Meanwhile, a case of fatal bacteremia in a preterm infant who had been given a probiotic product prompted the FDA to issue a warning letter to healthcare practitioners about probiotics in preterm infants, as well as warning letters to two probiotic manufacturers. These actions had the concerning effect of reducing access to probiotics for this population, despite the accumulated evidence that probiotics effectively prevent necrotizing enterocolitis in preterm infants. As outlined in ISAPP’s scientific statement on the FDA’s actions, the regulatory decision weighting the risks of commission over omission did not reflect the wealth of evidence for probiotic efficacy in this population and the low risk of harm.

Wider awareness of the postbiotic concept and definition

Scientific discussions on postbiotics continued throughout 2023, with several debates and conference sessions devoted to discussion of the postbiotic concept – including the status of metabolites in the definition. According to ISAPP board member Dr. Gabriel Vinderola PhD, who was a co-author on the definition paper and an active participant in many of these debates, the ISAPP definition is gaining traction and the debates have been useful in pinpointing further areas of clarification for the sake of regulators and other stakeholders. As shared with the audience at Probiota Americas 2023 in Chicago, Health Canada became the first regulatory agency to address the definition, and has started considering the term postbiotics under the ISAPP definition.

Advances in technologies for analyzing different sites in the digestive tract

When studying how biotics interface with the host via the gut microbiota, the science has relied mainly on analysis of fecal samples, with the majority of the GI tract remaining a ‘black box’. But a 2023 paper by Shalon et al., which was discussed at the ISAPP meeting in Denver, describes a device able to collect intestinal samples from different regions in the GI tract. Analysis of the metabolites and microbes indicated clear regional differences, as well as marked differences between samples in the GI tract versus fecal samples (for example, with respect to bile acids); an accompanying paper revealed novel insights into diet and microbially-derived metabolites. Efforts are underway across the world to develop smart pills or robotic pills that take samples all along the GI tract. Some devices have sensors that immediately signal to a receiver and others have been engineered to release therapeutic contents. Although these technologies may need more validation before they are useful in research or clinical contexts, they may greatly expand knowledge of the intestinal microbial community and how it interacts with biotic substances.

First convincing evidence linking intake of live microbes with health benefits

When an ISAPP discussion group in 2019 delved into the question of whether a higher intake of safe, uncharacterized live microbes had the potential to confer health benefits, it spurred a program of scientific work to follow. Efforts of this group in subsequent years led to the publication of an important study in 2023: Positive Health Outcomes Associated with Live Microbe Intake from Foods, Including Fermented Foods, Assessed using the NHANES Database. Researchers analyzed data from a large US dietary database and found clear but modest health benefits associated with consuming higher levels of microbes in the daily diet.

The benefits of live dietary microbes are being explored further in the scientific literature (for example, here, here, and here) and are likely to remain an exciting topic of study in the years ahead, building evidence globally for the health benefits of consuming a higher quantity of live microbes.

Increased interest in candidate prebiotics

Polyphenols have long been studied for their health benefits, but newer evidence suggests they may have prebiotic effects, achieving their health benefits (in part) through interactions with the gut microbiota. A theme at conferences and in the scientific literature has been the use of polyphenols to modulate the gut microbiota for specific health benefits. More than a dozen reviews on this topic were published in 2023, and several of them focused on how polyphenols may achieve health benefits in very specific conditions, such as diabetes or inflammatory bowel disease.

Another substrate receiving much attention for its prebiotic potential are human milk oligosaccharides (HMOs). HMOs, found in human milk, support a nursing infant’s health by encouraging the growth of beneficial gut microbes. Several articles in 2023 have delved into the mechanisms of HMO metabolism by the gut microbiota, and explored its potential as a dietary intervention strategy to improve gut health in adults.

Sharper focus on evidence for the health and sustainability benefits of fermented foods

Fermented foods are popular among consumers, despite only early scientific knowledge on whether and how they might confer health benefits (see ‘First convincing evidence linking intake of live microbes with health benefits’, above). ISAPP board member Prof. Maria Marco PhD co-authored a review led by Dr. Paul Cotter PhD in Nature Reviews Gastroenterology and Hepatology on the GI-related health benefits of fermented foods. The paper clearly lays out the potential mechanisms under investigation and identifies gaps to be addressed in the ongoing study of fermented foods.

As calls for reducing carbon footprints continue across the globe, plant-based fermented foods are being singled out as an area for innovation and expansion. One example of how these foods are being explored is through the HealthFerm project, a 4-year, 13.1 million Euro project involving 23 partners from 10 countries, which is focused on understanding how to achieve more sustainable, healthy diets by leveraging fermented foods and technologies.

Novel findings related to lactic acid bacteria

Lactic acid bacteria (LAB) are some of the most frequently-studied microbial groups, but scientists have only begun to uncover the workings of this diverse group of bacteria and how they affect a variety of hosts. These bacteria are used as probiotics and are often beneficial members of human and animal microbiomes, and they are also essential to making fermented foods. This year marked the first ever Gordon Research Conference on LAB in California, USA. Attendees showcased the diversity of research on lactic acid bacteria, and the meeting was energized by the early investigators present and by the interest in LAB in other disciplines including medicine, ecology, synthetic biology, and engineering. One example of a scientific development in this area was the further elucidation of the mechanism of Lactiplantibacillus plantarum’s extracellular electron transfer.

Progress on the benefits and mechanisms of action for probiotics to improve the effectiveness of cancer immunotherapies

Researchers have known for several years that the gut microbiota can be a determinant of the efficacy of cancer immunotherapy drugs that involve immune checkpoint blockade, but interventions that target the gut microbiota to improve response to immunotherapies have been slower to develop. This year saw encouraging progress in this important area, with probiotic benefits and mechanisms of action being demonstrated in several papers. Two of the most highly cited probiotics papers of the year centered on this topic: one showing how a tryptophan metabolite released by Limosilactobacillus reuteri (formerly Lactobacillus reuteri — see this ISAPP infographic) improves immune checkpoint inhibitor efficacy, and another paper that reviewed how gut microbiota regulates immunity in general, and immune therapies in particular.

Updated resource available on probiotics and prebiotics in gastroenterology

This year the World Gastroenterology Organisation (WGO) guidelines on probiotics and prebiotics were updated to reflect the latest evidence, with contributions from ISAPP board member Prof. Hania Szajewska MD PhD and former board member Prof. Francisco Guarner MD PhD. The guideline lists indications for probiotic and prebiotic use, and how the use of these substances may differ in pediatric versus adult populations. Find the guideline here.

Supercharging innovation: New session at ISAPP 2023 annual meeting brings industry and student members together to scientific innovation workshop in the field of biotics

/in News /by KC

Innovation in the biotics field is an important way to address some of our most important challenges in health, and ISAPP is the organization on the forefront of this innovation. This year ISAPP members are excited to debut a new workshop focused on innovation, June 26th at the 2023 ISAPP annual meeting in Denver. For this workshop, the Industry Advisory Committee (IAC) and the Students and Fellows Association (SFA) have joined forces and initiated a new way to share knowledge and promote networking opportunities.

How did the idea of the IAC-SFA innovation workshops come about?

The Innovation Workshops evolved from interest in how SFA and IAC might gain scientific insights from each other. What they have in common is a dedication to cutting-edge science. From this emerged the idea that these groups could convene several concurrent workshop sessions during the pre-meeting program focusing on innovation in the biotic field.

What will be discussed at the workshops?

The concurrent workshops will focus on four topics:

  • Innovation in prebiotics: What’s next? Chaired by Marla Cunningham
  • Latest advances in microbiome models and biotic screening techniques. Chaired by Brendan Daisley
  • Looking to the future for food and biotics. Chaired by Daragh Hill
  • Probiotic application beyond the gut: What have we learned and what’s next? Chaired by Mariya Petrova

Guided by IAC and SFA representatives, the attendees at each workshop will discuss topics of interest and attempt to answer relevant questions in the biotics field. For example:

  • What are the latest developments in the biotic field regarding research, discoveries, and techniques?
  • What problems are we currently facing, and how will we solve them?
  • What are the future opportunities, and how can we progress?

How will this advance innovation in the field?

The Innovation Workshops will provide a platform where IAC representatives and SFA members can benefit from the exchange ideas gained from unique viewpoints expressed. Industry members can hear firsthand about innovative research that students and fellows perform in their labs, while students can gain a deeper understanding of some of the considerations for commercialization and opportunities and barriers in the marketplace. By joining forces, we believe these workshops will form a bridge between industry and young generation scientists and provide valuable insights into to the latest biotic questions.

Through initiatives such as these, ISAPP drives scientific innovation in biotics for the benefit of the entire field.

ISAPP’s 2021 year in review

/in ISAPP Science Blog /by KC

By Mary Ellen Sanders, PhD, ISAPP Executive Science Officer

The upcoming year-end naturally leads us to reflect about what has transpired over the past 12 months. From my perspective working with ISAPP, I witnessed ISAPP board members and the broader ISAPP community working creatively and diligently to find solutions to scientific challenges in probiotics, prebiotics and related fields. Let’s look back together at some of the key developments of 2021.

ISAPP published outcomes from two consensus panels this year, one on fermented foods and one on postbiotics. The popularity of these articles astounds me, with 49K and 29K accesses respectively, as of this writing. I think this reflects recognition on the part of the scientific community of the value – for all stakeholders – of concise, well-considered scientific definitions of terms that we deal with on a daily basis. If we can all agree on what we mean when we use a term, confusion is abated and progress is facilitated. The postbiotics definition was greeted with some resistance, however, and it will remain to be seen how this is resolved. But I think ISAPP’s response about this objection makes it clear that productive definitions are difficult to generate. Even if the field ultimately embraces another definition, it is heartening to engage in scientific debate about ideas and try to find alignment.

Keeping with the idea of postbiotics, a noteworthy development this year was the opinion from the European Food Safety Authority that the postbiotic made from heat-treated Akkermansia muciniphila is safe for use as a novel food in the EU. Undoubtedly, this development is a bellwether for likely future developments in this emerging area as some technological advantages to postbiotics will make these substances an attractive alternative to probiotics IF the scientific evidence for health benefits becomes available.

Recognizing the existing need for translational information for clinicians, ISAPP developed a continuing education course for dietitians. Published in March, it has currently reached close to 6000 dietitians. This course focused on probiotics, prebiotics and fermented foods: what they and how they might be applied in dietetic practice. It is a freely available, self-study course and completion provides two continuing education credits for dietitians.

On a sad note, in March of this year, ISAPP suffered the loss of Prof. Todd Klaenhammer. Todd was a founding ISAPP board member, and directed many of our activities over the course of his 18-year term on the board. He was also my dear friend and major advisor for my graduate degrees at NC State many years ago.  As one former collaborator put it, “I was not prepared to finish enjoying his friendship and mentorship.” See here for a tribute to Prof. Klaenhammer on the ISAPP blog: In Memoriam: Todd Klaenhammer.

So where will 2022 lead ISAPP? The organization has now published five consensus definitions: probiotics, prebiotics, synbiotics, postbiotics and fermented foods – extending its purview beyond where it started, with probiotics and prebiotics. Through the year ahead, ISAPP is committed to providing science-based information on the whole ‘biotics’ family of substances as well as fermented foods. Our Students and Fellows Association is growing, supported by the opportunity for young scientists to compete for the Glenn Gibson Early Career Researcher Prize. We continue to see our industry membership expand. Through our new Instagram account and other online platforms, our overall community is increasing. The ISAPP board of directors continues to evolve as well, with several long-term members leaving the board to make room for younger leaders in the field who will direct the future of the organization. This applies to me as well, as I have made the difficult decision to depart ISAPP in June of 2023. Thus, hiring a new executive director/executive science officer is an important priority for ISAPP in 2022. My 20 years with ISAPP have seen the organization evolve tremendously, through the hard work of incredible board members as well as many external contributors. We will strive to make 2022 – our 20th anniversary – ISAPP’s best year yet.

ISAPP board members give a scientific overview of synbiotics in webinar

/in Consumer Blog, ISAPP Science Blog /by KC

Many kinds of products are labeled as synbiotics – but how do they differ from each other? And do they all meet the scientific criteria for synbiotic ingredients?

To demystify the science of synbiotics – including ISAPP’s definition published in 2020 – ISAPP is holding a free webinar: Synbiotics: Definitions, Characterization, and Assessment. Two ISAPP board members, Profs. Bob Hutkins and Kelly Swanson, present on the implications of the synbiotic definition for science and industry. They clarify the difference between ‘complementary’ and ‘synergistic’ synbiotics and cover the basics of meeting the criteria for synbiotic efficacy and safety. One challenge is learning when a synbiotic is required to have demonstrated both selective utilization of the microbiota in the same study that measures the health outcome. A Q&A is scheduled for the last 20 minutes of the webinar.

This webinar is for scientists, members of the public, and media who want a scientific overview on synbiotics as they appear in more and more consumer products.

The live webinar was broadcast on Friday, January 28th, 2022, from 10:00 am – 11:10 New York (Eastern) time.

Follow up from ISAPP webinar – Probiotics, prebiotics, synbiotics, postbiotics and fermented foods: how to implement ISAPP consensus definitions

/in ISAPP Science Blog /by KC

By Mary Ellen Sanders PhD, Executive Science Officer, ISAPP

On the heels of the most recent ISAPP consensus paper – this one on postbiotics – ISAPP sponsored a webinar for industry members titled Probiotics, prebiotics, synbiotics, postbiotics and fermented foods: how to implement ISAPP consensus definitions. This webinar featured short presentations outlining definitions and key attributes of these five substances. Ample time remained for the 10 ISAPP board members to field questions from attendees.

When considering the definitions, it’s important to remember that the definition is a starting point – not all criteria can be included. Using the probiotic definition as an example, Prof. Colin Hill noted that the definition is only 15 words – Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. This is a useful definition, stipulating the core characteristics of a probiotic. However, important criteria such as safety and identity are not specified in the definition yet are clearly delineated in the full paper on probiotics.

Several interesting topics emerged from this discussion, which will be explored in future blog posts. These include:

  • What is meant by host health? Microbe mediated benefits are numerous. But not all benefits are a benefit to host health. Benefits for user appearance, pets and potentially livestock may be measurable, economically important and desirable, but may not encompass ‘host health’.
  • What types of endpoints are appropriate for studies to meet the requirement of a health benefit? Endpoints that indicate improved health (such as symptom alleviation, reduced incidence of infections or quality of life measures) are targeted. Some physiological measures that may be linked to health (such as increased fecal short chain fatty acids or changes in microbiota composition) may not be sufficient.
  • What are the regulatory implications from these definitions? As suggested by the National Law Review article on the ISAPP consensus definitions, attorneys are interested in the scientific positions on how these terms are defined and characterized. Further, some regulatory actions – such as by Codex Alimentarius in defining probiotics – are underway. ISAPP is open to suggestions about the best way to communicate these definitions to regulators.
  • Is any follow-up by ISAPP to these papers anticipated in order to clarify criteria and provide simple guidance to their implementation?

Simple guidance to these substances can be found in the infographics: probiotics, probiotic criteria, prebiotics, fermented foods,  how are probiotic foods and fermented foods different, synbiotics, and postbiotics. As mentioned above, watch for blog updates on implementation of the definitions for different stakeholder groups.

The recording of this webinar is available here under password protection for ISAPP industry members only.

A roundup of the ISAPP consensus definitions: probiotics, prebiotics, synbiotics, postbiotics and fermented foods

/in ISAPP Science Blog /by KC

By Dr. Mary Ellen Sanders, PhD, ISAPP Executive Science Officer

ISAPP has long recognized the importance of precise definitions of the ‘biotic’ family of terms. As a scientific organization working to advance global knowledge about probiotics, prebiotics, synbiotics, postbiotics and fermented foods, we believe carrying out rigorous scientific studies—and comparing one result to another—is more difficult if we do not start with a clear definition of what we are studying.

Over the past 8 years, ISAPP has endeavored to bring clarity to these definitions for scientists and other stakeholders. ISAPP board members have met with other top experts representing multiple perspectives and specialties in the field to develop precise, useful and appropriate definitions of the terms probiotics, prebiotics, synbiotics, postbiotics and fermented foods. The definitions of these first four terms have all entailed the requirement that the substance be shown to confer a health benefit in the target host. Fermented foods have multitudes of sensorial, nutritional and technological benefits, which drive their utility. A health benefit is not required.

The problem with health benefits

The definitions provide significant advantages for the scientific community in terms of clarity but complexity arises when the same definitions are accepted by regulatory agencies. This requirement for a health benefit as part of the probiotic definition has been rigorously implemented in the European Union. Currently, with the exception of a few member states, the term probiotic is prohibited. The logic is that since a health benefit is inherent to the term probiotic and since there are no approved health claims for probiotics in the EU*, the term ‘probiotic’ is seen to be acting as a proxy for a health claim. This has frustrated probiotic product companies who believe they have met the scientific criteria for probiotics, yet cannot identify their product as a probiotic in the marketplace because they have not received endorsement of their claims by the EU. This is not an issue resulting from an unclear definition, since probiotics surely should provide a health benefit, but rather from a lack of agreement as to what level of evidence is sufficient to substantiate a health benefit.

ISAPP remains committed to the importance of requiring a health benefit for the ‘biotic’ family of terms (outlined in the table below). It’s clear that all of these definitions are meaningless unless the requirement that they confer a health benefit is considered as essential by all stakeholders. One could reasonably discuss whether the required levels of evidence for foods and supplements are too high in some regulatory jurisdictions, but the value of these substances collapses in the absence of a health benefit.

Summary of ISAPP consensus definitions

With the publication of the most recent ISAPP consensus paper, this one on postbiotics, I offer a summary below of the five consensus definitions published by ISAPP. Each definition is part of a comprehensive paper resulting from focused discussions among experts in the field and published in Nature Reviews Gastroenterology and Hepatology (NRGH). These papers are among the top most viewed of all time on the NRGH website and are increasingly cited by scientists and regulators.

Table. Summary of ISAPP Consensus Definitions of the ‘Biotics’ Family of Substances. Probiotics, prebiotics, synbiotics and postbiotics have in common the requirement for a health benefit. They may apply to any target host, any regulatory category and must be safe for their intended use. Fermented foods fall only under the foods category and no health benefit is required.

Definition Key features of the definition Reference
Probiotics Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host Grammatical correction of the 2001 FAO/WHO definition.

No mechanism is stipulated by the definition.

 

 Hill et al. 2014
Prebiotics A substrate that is selectively utilized by host microorganisms conferring a health benefit Prebiotics are distinct from fiber. Beneficial impact on resident microbiota and demonstration of health benefit required in same study. Gibson et al. 2017
Synbiotics A mixture comprising live microorganisms and substrate(s) selectively utilized by host microorganisms that confers a health benefit on the host Two types of synbiotics defined: complementary and synergistic. Complementary synbiotics comprise probiotic(s) plus prebiotic(s), meeting requirements for criteria for each. Synergistic synbiotics comprise substrate(s) selectively utilized by co-administered live microbe(s), but independently, the components do not have to meet criteria for prebiotic or probiotic. Swanson et al. 2020
Postbiotics Preparation of inanimate microorganisms and/or their components that confers a health benefit on the host Postbiotics are prepared from live microbes that undergo inactivation and the cells or cellular structures must be retained. Filtrates or isolated components from the growth of live microbes are not postbiotics. A probiotic that is killed is not automatically a postbiotic; the preparation must be shown to confer a health benefit, as well as meet all other criteria for a postbiotic. Salminen et al. 2021
Fermented Foods Foods made through desired microbial growth and enzymatic conversions of food components Fermented foods are not the same as probiotics. They are not required to have live microbes characterized to the strain level nor have evidence of a health benefit. Types of fermented foods are many and are specific to geographic regions. Compared to the raw foods they are made from, they may have improved taste, digestibility, safety, and nutritional value. Marco et al. 2021

 

 

*Actually, there is one approved health claim in the EU for a probiotic: Scientific Opinion on the substantiation of health claims related to live yoghurt cultures and improved lactose digestion (ID 1143, 2976) pursuant to Article 13(1) of Regulation (EC) No 1924/2006

ISAPP publishes continuing education course for dietitians

/in News, ISAPP Science Blog /by KC

For dietitians, it’s often difficult to find practical, up-to-date resources with a scientific perspective on probiotics, prebiotics, synbiotics and fermented foods. ISAPP is pleased to announce a new resource to fill this need – a Special Continuing Education Supplement in Today’s Dietitian titled, “Evidence-based use of probiotics, prebiotics and fermented foods for digestive health”. This free continuing education course also includes infographic summaries, links to supplementary information, and even some favourite recipes. US dietitians can earn 2.0 CPEUs for completing this self-study activity.

The resource was written by dietitian and assistant professor Dr. Hannah D. Holscher, along with two ISAPP board members, Prof. Robert Hutkins, a fermented foods and prebiotics expert, and Dr. Mary Ellen Sanders, a probiotic expert.

“We hope this course will give dietitians an overview of the evidence that exists for probiotics, prebiotics, synbiotics and fermented foods, and help explain some of the practical nuances around incorporating them into their practice,” says Sanders. “In addition, we believe that this course will be a scientifically accurate overview that can counter prevalent misinformation. It can serve as a useful resource for diverse array of professionals active in this field.”

What’s the evidence on ‘biotics’ for health? A summary from five ISAPP board members

/in Consumer Blog, ISAPP Science Blog /by KC

Evidence on the health benefits of gut-targeted ‘biotics’ – probiotics, prebiotics, synbiotics, and postbiotics – has greatly increased over the past two decades, but it can be difficult to sort through the thousands of studies that exist today to learn which of these ingredients are appropriate in which situations. At a recent World of Microbiome virtual conference, ISAPP board members participated in a panel that provided an overview of what we currently know about the health benefits of ‘biotics’ and how they are best used.

Here’s a summary of what the board members had to say:

Dr. Mary Ellen Sanders: Probiotics and fermented foods

  • Probiotics are “live microorganisms that, when administered in adequate amounts, confer a health benefit on the host”.
  • Unfortunately, published assessments of probiotic products available on the market show that these products often fall short of required evidence. For example, their labels may not adequately describe the contents (including genus / species / strain in the product); they may not guarantee the efficacious dose through the end of the shelf life.
  • Contrary to common belief, probiotics do not need to colonize in the target site (e.g. the gut), impact gut microbiota composition, be derived from humans, or be resistant to stomach acid and other gut secretions such as bile.
  • Fermented foods are those made “through desired microbial growth and enzymatic conversions of food components”. The recent increased interest in fermented foods may come from people’s increased awareness of the role of gut microbes in overall health, but it is important to note that we have little direct evidence that the transient effects of fermented food microbes on the gut microbiota actually lead to health benefits. With that said, observational studies suggest that consuming some traditional fermented foods is associated with improved health outcomes.

Prof. Dan Merenstein, MD: Probiotics – How do I know what to prescribe for adult health?

  • A (limited) survey showed that most dietary supplement probiotic products cannot be linked to evidence because they do not provide enough information to determine what evidence exists to support their use – especially strains in the product. However, there are some probiotic products that have robust evidence.
  • Should every adult take a probiotic? The best evidence supports probiotics for improved lactose digestion and for prevention of difficile infection. Probiotics have also been shown to prevent common illnesses; reduce the duration of gut symptoms; and perhaps even reduce antibiotic consumption.
  • Studies will reveal more about the microbiome and about how probiotics work, for whom and for what indications. As with diet, the answer will most likely not be same for each person.

Prof. Glenn Gibson: Prebiotics and Synbiotics

  • A prebiotic is “a substrate that is selectively utilized by host microorganisms conferring a health benefit”. Researchers can test these substances’ activity in various ways: batch cultures, micro batch cultures, metabolite analysis, molecular microbiology methods, CF gut models, with in vivo (e.g. human) studies being required. Prebiotics appear to have particular utility in elderly populations, and may be helpful in repressing infections, inflammation and allergies. They have also been researched in clinical states such as IBS, IBD, autism and obesity related issues (Gibson et al., 2017).
  • A synbiotic is “a mixture, comprising live microorganisms and substrate(s) selectively utilized by host microorganisms, that confers a health benefit on the host.” While more studies are needed to say precisely which are useful in which situations, synbiotics have shown promise for several aspects of health in adults (Swanson et al. 2020): surgical infections and complications, metabolic disorders (including T2DM and glycaemia), irritable bowel syndrome, Helicobacter pylori infection and atopic dermatitis.

Prof. Hania Szajewska, MD: Biotics for pediatric use

  • Beneficial effects of ‘biotics’ are possible in pediatrics, but each ‘biotic’ needs to be evaluated separately. High-quality research is essential.
  • It is important that we view the use of ‘biotics’ in the context of other things in a child’s life and other interventions.
  • Breast milk is the best option for feeding infants
  • If breastfeeding is not an option, infant formulae supplemented with probiotics and/or prebiotics and/or postbiotics are available on the market.
  • Pro-/pre-/synbiotic supplemented formulae evaluated so far seem safe with some favorable clinical effects possible, but the evidence is not robust enough overall to be able to recommend routine use of these formulae.
  • Evidence is convincing on probiotics for prevention of necrotizing enterocolitis in preterm infants.
  • Medical societies differ in their recommendations for probiotics to treat acute gastroenteritis in children – they appear beneficial but not essential.
  • Synbiotics are less studied, but early evidence indicates they may be useful for preventing sepsis in infants and preventing / treating allergy and atopic dermatitis in children.

Prof. Gabriel Vinderola: Postbiotics

  • The concept of non-viable microbes exerting a health benefit has been around for a while, but different terms were used for these ingredients. Creating a scientific consensus definition will improve communication with health professionals, industry, regulators, and the general public. It will allow clear criteria for what qualifies as a postbiotic, and allow better tracking of scientific papers for future systematic reviews and meta-analyses.
  • The ISAPP consensus definition (in press) of a postbiotic is: “A preparation of inanimate microorganisms and/or their components that confers a health benefit on the host”.
  • Postbiotics are stable, so no cold-chain is needed to deliver them to the consumer. Safety is of less concern because the microbes are not alive and thus cannot cause bacteraemia.
  • Research in the coming years will reveal more about postbiotics and the ways in which they can promote human health.

New synbiotic definition lays the groundwork for continued scientific progress

/in ISAPP Science Blog /by KC

By Karen Scott, Mary Ellen Sanders, Kelly Swanson, Glenn Gibson, and Bob Hutkins

When Glenn Gibson and Marcel Roberfroid first introduced the prebiotic concept in 1995, they also conceived that prebiotics could be combined with probiotics to form synbiotics. In 2011, Gibson and Kolida described additional criteria for defining synbiotics and proposed that synbiotics could have either complementary or synergistic activities.

In the past decade, nearly 200 clinical studies on synbiotics have been reported in the literature. Nonetheless, the term itself has been open to interpretation, and the existing definition – a probiotic plus a prebiotic – was inadequate to account for the synbiotic formulations described in the literature or available in the marketplace.

To provide clarity on the definition and lay the groundwork for progress in the years ahead, scientists working on probiotics, prebiotics, and gut health came together in an expert panel. The outcome of this panel, the ISAPP consensus definition and scope of the word synbiotic, has now been published in Nature Reviews Gastroenterology & Hepatology.

A diverse panel of experts

The panel of experts who met to discuss the definition of synbiotics in May, 2019, consisted of eleven interdisciplinary scientists in the fields of microbiology and microbial ecology, gastrointestinal physiology, immunology, food science, nutritional biochemistry, and host metabolism. The panel’s range of experience was important in order to ensure the definition made sense from different scientific perspectives. The panel met under the auspices of ISAPP and was led by Prof. Kelly Swanson.

An inclusive definition

Initially, it seemed logical that synbiotic could be defined as a combination of a probiotic and a prebiotic, with each component needing to meet the criteria for either probiotic or prebiotic according to the previous scientific consensus definitions (Hill, 2014; Gibson, 2017). However, as the group discussed different scenarios and combinations, it became clear that this narrow characterization of a synbiotic could place undue emphasis on the individual components of a synbiotic rather than the combination of these components. For example, the original definition would not include a combination of inulin (a prebiotic) with live microorganisms that did not have probiotic status, even if live microbes in the host selectively utilized inulin and the combination was shown to confer a health benefit.

The definition of synbiotic agreed upon by the panel is: “A mixture, comprising live microorganisms and substrate(s) selectively utilized by host microorganisms, that confers a health benefit on the host.”

The panel discussed exactly which microorganisms must be targeted by the substrate in a synbiotic and decided that the targeted ‘host microorganisms’ can include either autochthonous microbes (those already present in the host) or allochthonous microbes (those that are co-administered).

Further, the panel defined two distinct types of synbiotics: complementary and synergistic. In a ‘synergistic synbiotic’, the substrate is designed to be selectively utilized by the co-administered microorganism(s)—and do not necessarily have to be individual probiotics or prebiotics, as long as the synbiotic itself is health promoting. In a ‘complementary synbiotic’, an established probiotic is combined with an established prebiotic designed to target autochthonous microorganisms— therefore each component of a complementary synbiotic must meet the minimum criteria for a probiotic or a prebiotic.

The definition is purposefully inclusive, so a synbiotic could be established for different hosts, e.g. humans, companion animals, or agricultural animals. Even subsets of these hosts (those of a certain age or living situation) could be targeted by synbiotic products. Moreover, products may be called synbiotics if they target areas of the host’s body outside of the gut (e.g. the skin).

Implications for study design

According to the new definition, different types of studies must be designed for synergistic synbiotics versus complementary synbiotics. For the former, a single study must demonstrate both selective utilization of the substrate and a health benefit. For complementary synbiotics, however, it is only necessary to show a health benefit of the combined ingredients; it is not necessary to show selective utilization of the prebiotic substrate, since selective utilization should have already been established.

The panel remained open to different scientifically valid approaches to demonstrate selective utilization of the substrate. Further, the nature of the ‘health benefit’ was not prescribed, but to the extent biomarkers or symptoms are used, they must be validated.

Continuing scientific progress

The field of synbiotics is evolving – some studies exist to show human health benefits deriving from synbiotic ingredients. While the studies on individual components (probiotics and prebiotics separately) may guide those in the field, there is the possibility that we will find novel uses and applications for synbiotics in the years ahead.

Causality is an important issue that scientists will need to address in this field. The definition of synbiotics rests on an important concept originally advanced in the definition of prebiotics: evidence of health benefit plus selective utilization of the substrate by microbes must be demonstrated. More investigations of causal links between these two things will have to be explored; this is closely connected with ongoing work to uncover probiotic and prebiotic mechanisms of action.

This definition is a first step—and it is fully expected that the field will evolve in the years ahead as more data are generated on the benefits of synbiotics for human and animal hosts.

What makes a synbiotic? ISAPP provides a sneak peek at the forthcoming international scientific consensus definition

/in Consumer Blog, ISAPP Science Blog /by KC

By Kristina Campbell, science and medical writer

The word ‘synbiotic’ is found on the labels of many different products, from supplements to chocolate bars, and it has generally been understood to be a combination of a probiotic and a prebiotic. But what happens when scientists want to test whether these combination products really deliver any health benefits? Can these products be tailored to have specific effects on the body or on the human gut microbiota? Agreeing on a clear definition of synbiotics is needed to provide focus for scientific research in this area, to facilitate the design of studies, and to allow for progress wherein their health effects are uncovered.

The scientific definition of synbiotic was the central topic of the international scientific panel brought together by ISAPP in May 2019 in Antwerp, Belgium. Members of the panel, eleven of the top academic experts in the field of probiotics and prebiotics, gathered to clarify a scientifically valid approach for use of the word ‘synbiotic’, and to communicate this by position paper. The outcome of this consensus panel is currently in press at Nature Reviews Gastroenterology & Hepatology.

Kelly Swanson, Professor in the Department of Animal Sciences and Division of Nutritional Sciences at University of Illinois at Urbana-Champaign, chaired the panel and led the paper’s publication. Swanson has been studying gastrointestinal health in both humans, companion animals (dogs and cats) and rodent models for the past 20 years—and having followed the rapid advances in the field of probiotics and prebiotics during those two decades, he knew the task of creating a synbiotic definition would not be easy.

He says, “The field is highly complicated, so an interdisciplinary panel was essential. The main areas of expertise included microbiology and microbial ecology; gastrointestinal physiology; immunology; food science; nutritional biochemistry and host metabolism.”

A timely discussion

According to Swanson, an increase in research interest, built on a foundation of recent scientific and technical gains, made this the right time to come to consensus on a synbiotic definition. He says, “Over the past decade, technological advances have allowed scientists to study the gut microbiome at a molecular level. In addition to characterizing the composition of the gut microbes, researchers are learning more about their biological activity and how they may impact host health.”

Furthermore, clarity about the definition was urgently needed because of the rapidly growing synbiotics market. Consumers seem to be more aware of synbiotics than ever, but they face a bewildering array of product offerings labeled as ‘synbiotic’ without a clear understanding of what that term entails and with no framework for establishing scientific efficacy. Swanson says, “As the field has moved forward and the sales of probiotics and prebiotics have increased, there has been more interest in combining substances to enhance efficacy. Some of these combinations may function as synbiotics, but it is not guaranteed. Rather than randomly combining substances together, there should be scientific rationale supporting their use.”

Clarifying the concept

One of the first questions the panel members had to tackle was whether to stick to the idea of a synbiotic as ‘probiotic plus prebiotic’, thus leaning heavily on the ISAPP-led international consensus definitions of probiotics and prebiotics published in 2014 and 2017, respectively. But the panel members decided this narrow scope would ultimately limit innovation in the synbiotic category.

Swanson explains, “While many synbiotics may be composed of an established prebiotic and established probiotic, the panel did not want to restrict scientific advances in the synbiotic category by requiring use of components already established on their own.”

As a result, he says, previously untested live microbes and potential prebiotic substances could be considered a synbiotic if the combination showed efficacy, and if the health benefit came from administering both the live microbe and the substrate it utilized—that is, the microbe together with its ‘food’.

Another conclusion from the panel is that probiotics (with known health benefits) and prebiotics (with known health benefits) cannot be called synbiotics unless they have been tested together. “There should be a rationale supporting the combination used, and then testing of the combination to confirm its efficacy,” says Swanson.

The panel suggests a synbiotic may be composed of either of the following, as long as efficacy is demonstrated for the combination:

  • Established probiotic + established prebiotic (each component meeting the efficacy and mechanistic criteria for each)
  • Previously untested live microbe + a substrate that is selectively utilized by the co-administered live microbe

Further details, including two different ‘categories’ of synbiotics, will be provided in the published paper.

In addition to the definition, the publication will cover the history of synbiotic-type products, how these products can be characterized, levels of evidence that currently exist versus levels of evidence desired, points about safety documentation and reporting, and relevant characteristics of the target hosts.

A remaining challenge—not just for the expert group, but also across the field—is the difficulty of establishing causal links between substances’ effects on the gut microbiota (e.g. ‘selective utilization’ of a substrate) and health outcomes.

While the publication of the synbiotic definition will be an important milestone, Swanson anticipates further discussion in the years ahead. “As more is learned, I expect the criteria for assessing synbiotic efficacy will continue to change,” he says.

An update on the scientific consensus definition of synbiotic was presented to ISAPP members at the 2020 virtual meeting in June.

 

ISAPP’s 2019 annual meeting in Antwerp, Belgium: Directions in probiotic & prebiotic innovation

/in featured, News /by ISAPP

Kristina Campbell, Microbiome science writer, Victoria, British Columbia

We live in a time when a simple Google search for ‘probiotics’ produces over 56.8 million hits; a time when almost everyone has heard of probiotics through one channel or another, and when an ever-increasing variety of probiotic and prebiotic products is available in different regions of the world.

The next five to ten years will be telling: will probiotics and prebiotics join the ranks of other trendy health products that experienced a wave of popularity before something else took their place? Or will they be recognized as important contributors to health through the lifespan, and establish a permanent position in the clinical armamentarium?

According to the global group of 175 academic and industry scientists who met for the ISAPP annual meeting in Antwerp (Belgium) May 14-16, 2019, one thing above all is necessary for the world to recognize the significance of probiotics and prebiotics for health: scientific innovation. Not only are technological capabilities advancing quickly, but also, new products are being evaluated by better-educated consumers who demand more transparency about the health benefits of their probiotics and prebiotics.

Participants in the ISAPP conference came together to talk about some of the leading innovations in the world of probiotics and prebiotics. Here are three of the broad themes that emerged:

Better health through the gut-brain axis

Gut-brain axis research is rapidly growing, with many investigators in search of probiotic and prebiotic substances capable of modulating brain function in meaningful ways. Phil Burnett of Oxford (UK) presented on “Prebiotics, brain function and stress: To what extent will prebiotics replace or complement drug therapy for mental health?”. Burnett approached the challenge by administering prebiotics to healthy adults and giving them a battery of psychological tests; in one experiment he found people who consumed a prebiotic (versus placebo) showed benefits that included reduced salivary cortisol and positively altered emotional bias. For those with diagnosed brain disorders, Burnett concludes from the available data that prebiotics have potential anxiolytic and pro-cognitive effects in these populations, and that prebiotics may eventually be used to complement the established treatments for some mental disorders.

Short-chain fatty acids (SCFAs) are of interest as potential modulators of brain function, but so far very little research has been carried out in this area. Kristin Verbeke of Leuven (Belgium) gave a talk entitled “Short-chain fatty acids as mediators of human health”, which covered the extent to which interventions with fermentable carbohydrates can alter systemic SCFA concentrations (rather than gut SCFA concentrations)—since the former are more relevant to effects on the brain.

Also, a students and fellows feature talk by Caitlin Cowan of Cork (Ireland) explored a role for the microbiota in psychological effects of early stress. She spoke on the topic “A probiotic formulation reverses the effects of maternal separation on neural circuits underpinning fear expression and extinction in infant rats”.

A clear definition of synbiotics

Immediately before the main ISAPP meeting, a group of experts met to propose a consensus definition of ‘synbiotic’, with the objective of clarifying for stakeholders a scientifically valid approach for the use of the increasingly-popular term. A key point of discussion was whether the probiotic and prebiotic substances that make up a synbiotic are complementary or synergistic. And if the two substances have already been tested separately, must they be tested in combination to give evidence of their health effect? The group’s conclusions, which will undoubtedly steer the direction of future R&D programs, will be published in a forthcoming article in Nature Reviews Gastroenterology & Hepatology.

Probiotics and prebiotics for pediatric populations

Probiotics and prebiotics have been studied for their health benefits in pediatric populations for many years, but in this area scientists appear to have a renewed interest in exploring new solutions. Maria Carmen Collado of Valencia (Spain) covered “Probiotic use at conception and during gestation”, explaining some of the most promising directions for improving infant health through maternal consumption of probiotics.

In recent years, technical advancements have made possible the large-scale production of some human milk oligosaccharides (HMOs); it is now an option to administer them to infants. Evelyn Jantscher-Krenn of Graz (Austria) presented a novel perspective on HMOs, with “HMOs in pregnancy: Roles for maternal and infant health”, giving a broad overview of the many ways in which HMOs might signal health status and how they might be fine-tuned throughout a woman’s pregnancy.

A discussion group on “prebiotic applications in children”, chaired by Dr. Michael Cabana of San Francisco (USA) and Gigi Veereman of Brussels (Belgium), discussed evidence-based uses of prebiotics in children in three areas: (1) prevention of chronic disease; (2) treatment of disease; and (3) growth and development. While the latter category has the best support at present (specifically for bone development, calcium absorption, and stool softening), the other two areas may be ripe for more research and innovation. The chairs are preparing a review that covers the outcomes of this discussion group.

Next year in Banff

ISAPP’s next annual meeting is open to scientists from its member companies and will be held on June 2-4, 2020 in Banff, Canada.

ISAPP plans consensus panel on synbiotics

/in featured, News /by Mary Ellen Sanders

The term ‘synbiotic’ – which refers to a substance that combines both a probiotic and prebiotic – lacks a concise, modern definition. Stakeholders, including researchers, regulatory experts, consumers, marketers, industry scientists and healthcare providers, would benefit from a clear definition of synbiotics, a concise review of the state of the science of synbiotics, and a clarification of what kinds of products fall under the synbiotic scope.

ISAPP will convene a panel of top scientific experts on May 13th in Antwerp to develop a consensus around this topic. This panel will be chaired by Prof. Kelly Swanson, The Kraft Heinz Company Endowed Professor in Human Nutrition, Professor in the Department of Animal Sciences and Division of Nutritional Sciences, and Adjunct Professor in the Department of Veterinary Clinical Medicine at the University of Illinois at Urbana-Champaign. Prof. Swanson is known for his research on the mechanisms by which nutritional interventions affect health outcomes in both animals and humans. He is a co-author of the 2017 ISAPP consensus statement on the definition and scope of prebiotics.

As with the ISAPP consensus statements on probiotics (Hill et al. 2014) and prebiotics (Gibson et al. 2017), ISAPP is working with Nature Reviews Gastroenterology and Hepatology to publish the outcome of the synbiotics panel.

ISAPP’s focus on the science of probiotics and prebiotics makes it uniquely positioned to champion a panel of experts to discuss the definition and scientific justification for synbiotics.

The consensus panel members are:

  • Kelly Swanson, University of Illinois at Urbana-Champaign, USA (chair)
  • Glenn Gibson, University of Reading, UK
  • Gregor Reid, University of Western Ontario, Canada
  • Kristin Verbeke, University of Leuven (KU Leuven), Belgium
  • Nathalie Delzenne, Université Catholique de Louvain, Belgium
  • Robert Hutkins, University of Nebraska-Lincoln, USA
  • Karen Scott, University of Aberdeen, UK
  • Raylene Reimer, University of Calgary, Canada
  • Hannah Holscher, University of Illinois at Urbana-Champaign, USA
  • Meghan Azad, University of Manitoba, Canada
  • Mary Ellen Sanders, ISAPP
