Assessing the Value of Dietary Live Microbes: Toward a Recommended Intake That Supports Health

Scientific evidence points to a role for dietary live microbes in human health. There is an opportunity to evaluate the degree to which existing evidence supports development of a dietary recommendation for live microbes, as well as to identify gaps […]

The Identification of Microbially-Derived Metabolites as Biomarkers: What Changes of Which Metabolites Matter for Health?

Identifying microbially‐derived metabolites that may serve as biomarkers for health, or metabotyping, is a necessary step to understanding the role of the microbiome in human health. Ultimately, knowing what metabolites (including presence and quantity) matter for health can inform development […]

Development of a Research Framework for Evidence-Based Assessment of Potential Carcinogens in Human Diets

Risk assessment of chemicals that are potentially carcinogenic in humans often relies on extrapolation from carcinogenicity bioassays. There is a growing belief in the scientific community that evidence-based risk assessment can replace historical, over-protective guidance-based approaches. However, there is no […]

Impact of Dietary Sweetness Exposure on Future Dietary Intake: Reanalysis of Existing Intervention Trial Data

Several global health authorities recommend avoidance of sweetness in the diet from both sugar and low-calorie or non-nutritive sweeteners, due to concerns that intake of sweet taste drives a preference for more sweetness, with ultimate negative consequences for energy intake […]

Effect of Low-Calorie Sweetener Intake on Glycemic Response

Globally, dietary guidance recommends reducing added and total sugars in the diet to reduce caloric intake and chronic disease. Low-calorie sweeteners (LCS) present an option for reducing calories while providing sweetness in the diet, but questions remain regarding the effects […]

Standardizing Method and Development of Normal Values to Measure Human Small Intestinal and Colonic Permeability

Maintaining—or restoring to normal—gut barrier function is not currently recognized as a physiologic benefit of fiber consumption, in part due to lack of agreement by experts in the field on how to define and measure normal gut barrier function in […]

Metabolic and Physiological Properties of Rare Sugars Review Paper

Rare sugars are monosaccharides or disaccharides that exist in small quantities in nature and have unique metabolic and physiological properties that help distinguish them from more commonly consumed sugars like fructose and glucose. Due to their unique properties, rare sugars […]

Global Comparison of How Short-Term Blood Glucose Response to Food is Measured and Translated

The wide range of methods used to describe the impact of food on short-term glycemic response makes it challenging to apply research results broadly, including but not limited to its use on food labels. The choice of approach should be […]

Updating the Metal Dietary Exposure Screening Tool

The IAFNS Food and Chemical Safety Committee invests in the training and education of future scientists and leaders in the fields of food and chemical safety and food toxicology by supporting a Summer Fellowship Program for doctoral students. This project […]

Effect of the Use of Potassium-Based Sodium Replacers on Sodium and Potassium Intakes of the US Population

Sodium intake in the US population exceeds recommendations, and efforts have long been underway to reduce the amount of sodium in foods. Salt in the form of NaCl is the largest source of sodium in processed foods. Given the particular […]

Protein Intake and Human Health: Implications of Units of Protein Intake

Current dietary recommendations for protein intake are expressed as grams per kilogram of body weight in recognition of its role as the structural building blocks for lean body mass. Although FAO/WHO acknowledges that this recommendation is appropriate for those in […]

Sampling of Post-Hurricane Florence Floodwater for Human Foodborne Pathogens

Heavy rainfall and flooding following a hurricane can massively impact water quality, especially via runoff from agricultural and industrial operations. The IAFNS Food Microbiology Committee is supporting researchers at North Carolina State University to examine the emergence, potential routes of […]
