Assessing the science supporting the use of prebiotics to rebalance and maintain health
Background
A prebiotic is a food ingredient that selectively stimulates growth and/or the activity of microbial species inhabiting the host, which may confer him health benefits.
Objectives
A better understanding of mechanisms of prebiotics is still needed. The Task Force aims at providing mechanistic insights linking prebiotics to individual health benefits.
Likewise, it will identify and explore the health benefits of prebiotic fermentation (gut-brain, gut-kidney, gut-liver, metabolic syndrome).
Impact
The recent publication on ‘Gut Microbiota Functions: Metabolism of Nutrients and Other Food Components’ and the ‘Systematic Review of The Effects of The Intestinal Microbiota on Selected Nutrients and Non-Nutrients’ have been cited 180 times.
The collaboration with the Probiotics Task Force resulted in a Concise Monograph that summarises the science and principles valid for prebiotics, probiotics and synbiotics today. This publication is often used as teaching material by students and SMEs.
The publication ‘Prebiotic Effects: Metabolic and Health Benefits’ summarising beneficial health effects of specific prebiotics consumption has been cited 1,353 times.

Revealing the Mechanistic Role in Human Physiology and Beneficial Aspects of Short Chain Fatty Acid (SCFA) Production in the Gastro-Intestinal Tract (GIT)
Background & Objectives
Increased SCFA production from prebiotic consumption is considered as (part of) the mechanism through which prebiotics exert beneficial effects on gut health and metabolic function. Since SCFA production is often not considered as a health benefit as such, this activity is intended to:
- review and evaluate coherent evidence of the beneficial action(s) of SCFAs,
- clarify whether it is scientifically justified and appropriate to consider alterations in SCFA production as a health benefit/ biomarker;
- and obtain a consensus view on microbial SCFA formation as a benefit for human physiology.
Output
The conclusions on the link between health and SCFA production were refined during the workshop ‘The Role of Gut Derived Short Chain Fatty Acids in Human Health’ (28-29 November, Brussels, Belgium). An enlarged panel of multidisciplinary experts contributed to this refinement.
These conclusions will provide guidance to facilitate the design and interpretation of academic and industrial prebiotic research. Furthermore, the consensus may support the development of health claims (procedures) on prebiotics.
Understand the Relationship Between the Molecular Structure and the Effects of Prebiotic Compounds on Microbiota and its Metabolites
Background & Objectives
Prebiotic compounds display great variability and so far, there is no clear conclusion about the relationship between structure-function. The activity generally considers fermentable carbohydrates (prebiotics, candidate prebiotics and oligosaccharides) to:
- determine the relationship between specific structure characteristics of fermentable carbohydrates and the impact on the composition and activity of the gut microbiota;
- investigate the metabolic capacity of human gut microbiota and consider potential direct effects of the fermentable carbohydrates on the host (without being fermented first) as a secondary objective.
Output
The outcome from this activity, in the form of a peerreviewed paper, will support the understanding of how carbohydrate bioengineering tools to manufacture next generation prebiotics can be reasonably applied.
Joint Nutrition Cluster Activity on ‘Mechanistic Insights into the Gut-Brain Axis’ – In collaboration with Early Nutrition and Long-Term Health; Health Benefits Assessment of Foods; Nutrition, Immunity & Inflammation; Nutrition & Brain Health and Probiotics Task Forces – New
Background & Objectives
Currently, half of the literature available on the gut-brain axis is state-of-the-art reviews or correlative studies and comprehensive mechanistic insights underlining the bidirectional communication between the gut and the brain are lacking.
In this context, several Nutrition Task Forces decided to join forces to understand where we stand today regarding the mechanisms. Together the Task Forces will:
- focus on translational aspects from pre-clinical to clinical studies;
- focus on lifespan-related changes (but not diseaserelated) in gut structure and function which play a role in long-term immune and brain health;
- discuss the nutritional and lifestyle interventions with positive impact on the lifespan gut structure/function and thus on immune and brain health.
Output
A workshop held in December 2019 brought together key experts from different fields of expertise to debate and discuss on the current knowledge and data gaps.
A perspective paper on this gap analysis is under construction. This publication will be followed by a series of web-seminars to discuss the identified gaps in more details.
