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.

Methods in Nutrition & Gut Microbiome Research: An American Society for Nutrition Satellite Session

Nutrients, 2023

The microbial cells in the human gut form an ecosystem that regulates and maintains human health. IAFNS has joined the American Society for Nutrition in an effort to harmonize approaches to studying the gut microbiome to better explore these connections. The scientific session summarized how improving the accuracy, precision and comparability of microbiome research will build understanding of the associations between the microbiome, health and disease prevention.

Mapping the Available Evidence on the Impact of Ingested Live Microbes on Health: A Scoping Review Protocol

BMJ Open, 2023

Some researchers think that the regular consumption of safe, live microbes confers health-promoting attributes, including the prevention of disease. To address this hypothesis, we propose a scoping review to assess the large amount of scientific literature that is now available on this topic.

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

Metabolites, 2022

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.
