The Nutrition for Gut Health Committee advances and communicates the scientific understanding of the impact of diet and dietary constituents on gut and host health.

(This Committee represents the evolution of the Gut Microbiome Committee.)

Strategic Focus Area

  • Advance shared definitions and approaches to measurement of gut health and gut microbiome across stakeholders.
  • Evaluate and advance the evidence for nutrition support of optimal gut and host health.
  • Communicate the evidence that underpins how diets and dietary constituents impact measures of gut health and other systems influenced by gut physiology.
  • Through the Live Dietary Microbes Subcommittee, gather, develop, and drive science- and evidence-based decisions on dietary recommendations for live microbes (learn more here). See news story about the promise of research on dietary microbes for health.

Current Work

This committee has various work underway:

Webinar Series

The Committee has initiated a webinar series to help guide the committee’s research and projects.

Establishing What Constitutes a Healthy Human Gut Microbiome: State of the Science, Regulatory Considerations, and Future Directions

IAFNS previously took on the task of defining a “healthy gut microbiome,” and the outcome of this effort was published by Backhed et al. in 2012. Since that time, the body of work on gut microbiome has grown exponentially. In 2018, >40 invited academic, government, and industry experts gathered to evaluate progress toward this definition and explore the question: Can a Healthy Gut Microbiome be Defined Through Quantifiable Characteristics?

Workshop Report: Toward the Development of a Human Whole Stool Reference Material for Metabolomic and Metagenomic Gut Microbiome Measurements

This report represents the consensus opinions of workshop participants on developing general criteria for metabolite selection and a preliminary list of proposed metabolites. The paper describes some of the strengths and limitations of this initiative given the current state of gut microbiome research.

Diet-Related and Gut-Derived Metabolites and Health Outcomes: A Scoping Review.

A scoping review to map evidence about the health impact of gut microbiota-derived metabolites is now available. The researchers found a need to conduct more prospective studies, including clinical trials. Researchers identified metabolites and conditions for which systematic reviews are warranted to characterize the direction and magnitude of metabolite-disease associations.

IAFNS will present at the American Society for Nutrition Annual Meeting -- NUTRITION 2024 -- showcasing new work on funded projects.

Meeting site: https://nutrition.org/n24/
Registration site: https://www.mcievents.com/nutrition2024/ Emerging Technology for Improved Diet and Microbiome Analysis Expand

Monday, July 1, from 4:00-5:30 p.m. Central Time

In partnership with the Nutritional Microbiology GEM.

Human research examining how diet and gut microbiome interactions influence health is underway globally in the form of large-scale cohort studies as well as smaller dietary interventions. Researchers working to identify new diet-gut microbe relationships face a lack of resolution and a high degree of variability in both dietary and microbial data.

New tools for dietary data collection, and gut microbiota analysis are rapidly being developed and existing tools adapted to help address these issues. As this field rapidly moves forward, we need to understand how to best apply new methods across varied study groups to obtain the most accurate and precise results possible.

By convening speakers with expertise in diet assessment, gut microbiology, and computational biology this symposium will address how novel methods in diet assessment, microbiology and machine learning/AI are being applied to advance understanding of diet-microbiome interactions in health and disease.
