Reconciling Personalized Nutrition and the DGA: Should and Could Dietary Guidelines be Personalized?

Recorded June 22, 2022 IAFNS is a Continuing Professional Education (CPE) provider with the Commission on Dietetic Registration (CDR). CDR Credentialed Practitioners will receive 1.0 Continuing Professional Education Units (CPEUs) for completion of this recorded webinar until June 22, 2025. Description: The Dietary Guidelines for Americans (DGA) are intended for the US population, which includes […]

Understanding and Advancing Best Practices for Human Nutrition & Gut Microbiome Research

  In 2017, the National Institutes of Health (NIH) collaborated with the US Department of Agriculture, Agricultural Research Service (USDA-ARS) to develop and document “Considerations for Best Practices in Studies of Fiber or Other Dietary Components and the Intestinal Microbiome” (Klurfeld et al. 2018). The primary recommendation resulting from this exchange was to “describe dietary […]

Understanding Adolescence as a Critical Period for Immediate and Long-term Cognitive Health Impact – Systematic Review

It is well-established that the prenatal period and infancy (the first 1000 days) are critical for cognitive development, and nutrition during these periods can impact cognitive performance later in life. Specific nutrients are therefore emphasized during pregnancy and infancy, to include choline, iron, folate and iodine, with emerging evidence for a role of many other […]

Applying Retrospective Harmonization to the Field of Nutrition and Cognitive Health

  The 2020 Dietary Guidelines Advisory Committee (DGAC) explored neurocognitive health through several systematic reviews and was faced with a literature having “considerable variation in testing methods, inconsistent validity and reliability of cognitive testing methods, and differences between dietary patterns and cognitive outcomes examined,” reducing the ability to draw conclusions (USDA/HHS 2020). The lack of […]

Logical Fallacies in the Food and Nutrition Conversation: How to Spot Them & Defuse Them

Recorded January 18, 2023 IAFNS is a Continuing Professional Education (CPE) provider with the Commission on Dietetic Registration (CDR). CDR Credentialed Practitioners will receive 1.5 Continuing Professional Education Units (CPEUs) for completion of this recorded webinar until January, 2026. Description: Talking about food can get complicated. Discussions on nutrition can be even more complex. The […]

Competitive Exclusion for Microbial Control of Foods

Sample Collection, Preservation, and Data Analysis in Gut Microbiome Research: Current Methods and Potential Impact on Results

The development of dietary guidance relies upon the ability to synthesize a body of evidence and arrive at a reasonably well-supported conclusion. Although publications have purported to identify characteristics of a “healthy gut microbiome”, the one certainty at present is that gut microbiome is highly variable across individuals. In addition, the reality is that gut […]

Opportunities and Challenges to Sodium Reduction in Food Service and Strategies to Foster Progress

The objective of this project is to document the outcomes of a dialogue with leaders from the food service sector, government, and academia to understand the challenges and opportunities related to sodium reduction in the food service sector. This work related to the dynamics, initiatives, and challenges in the food service sector will help identify […]

Reconciliation of Differences between Observational Studies and Randomized Controlled Trials: A Case Study on Low Calorie Sweeteners

Scientific evidence is commonly categorized into levels based on quality of evidence, commonly referred to as the hierarchy of evidence. The complexity of evaluating study quality based on study design becomes problematic for dietary exposures and health outcomes with conflicting evidence observed in observational studies and RCTs. Such conflicting evidence is well documented for low […]

Understanding Authoritative Decisions Around Selection and Validation of Cognitive Performance Measures – with a Focus on Nutrition-Related Research

The objective of this project is to document the outcomes of an expert roundtable with the goal to understand decisions and approaches that underlie cognitive assessment tool selection by authoritative groups. This effort aims to enable the advancement of evidence evaluation and evidence development to support future dietary guidance, and to document learnings and how […]

Framework for Defining Suitable Recycled Resin Based on Intended End-Use and Characterizing Potential Chemicals of Concern

Changes in consumer behavior and growth in convenience foods, cosmetics, and pharmaceutical products complicates the use of recycled materials by requiring sophisticated and complex multilayer packaging solutions and increasing the amount of packaging waste. Many packaging materials, such as multilayer flexible and rigid plastics, are primarily sent to landfills. This project will develop a common […]

Development of a Human Whole-Stool Reference Material – NIST Collaboration

Over the past 10+ years, it has become evident that the human gut microbiome plays a critical role in a vast and disparate set of health and disease states; including diabetes, obesity, cancer and depression. To identify new biomarkers that may serve as disease indicators and to understand biologically‐relevant properties of the human gut microbiome, […]
