IAFNS is presenting at the American Society for Nutrition Annual Meeting – NUTRITION 2025 – and will showcase new work on funded projects.

Session Topic for NUTRITION 2025:

What is ‘Gut Health’? From Research Concepts to Implementation.

“Gut health” has become a part of the common lexicon to describe health in a broader sense. In marketing campaigns, gut health is often a catchall phrase that can mean any number of health-promoting outcomes. While gut health lacks a clear definition, the term is increasingly used in human and veterinary medicine, but there are unanswered questions: Is gut health different from digestive health or GI health? What is the overall importance of gut health for individuals who do not have bowel disease? How should gut health be measured? For the latter, a variety of criteria have been proposed, but not yet agreed-upon. In this session, work by experts will be presented to shed light on what constitutes a healthy gut and how that is measured, with implications for scientific, industrial, and regulatory communities. Presented in collaboration with the International Scientific Association for Probiotics and Prebiotics (ISAPP).

Associations Between Live Dietary Microbe Intakes and Health Outcomes, Analyses of the KNHANES 2016-2020 Data

Abstract

Objectives: The consumption of live microbes, beyond probiotics, is associated with health benefits.^1,2 This study aimed to quantify live microbe intake in 2016-2020 South Korean National Health and Nutrition Examination Survey (KNHANES), and to investigate the associations between live microbe intake and health outcomes.

Methods: We developed a KNHANES live microbe classification system based on the Sanders system³ and divided KNHANES food codes that overlapped with NHANES into four categories: no live microbe or low (<10⁴CFU/g), medium (10⁴–10⁷ CFU/g), and high (>10⁷ CFU/g) levels. Microbe data on various types of kimchi were obtained from World Kimchi Institute and data on other non-overlapping food codes were determined based on literature and authoritative reviews. We performed descriptive analyses on live microbe intakes among adults aged 19 y and older. We then conducted survey-weighted adjusted regression analyses to evaluate the relationship between live microbe intake and cardiometabolic health outcomes, controlling for age, sex, body mass index, household income, physical activity level, current smoking status, and alcohol intake.

Results: The mean daily intake of medium live microbe foods was 179.48 g in the South Korean population, while high live microbe foods averaged 122.49 g. Kimchi contributed a significant portion, with a mean intake of 102.44 g. An additional 100-g intake of medium or high live microbe–containing foods was associated with a lower C-reactive protein (coefficient: -0.006; 95% CI: -0.01, -0.002 mg/dL) and a lower weight (coefficient: 0.06; 95% CI: 0.041, 0.038 kg). The associations were significantly different among age groups. We did not find statistically significant associations between live microbe intake and other health outcomes.

Conclusions: This study provides new data on dietary intakes of live microbes and their potential health benefits in a nationally representative data set of South Korean adults.

Emerging Technology for Improved Diet and Microbiome Analysis

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.
