Current Opportunities:

Advancing Exposure Assessment for Food Contaminants Through Implementation of Probabilistic Modeling

The IAFNS Food and Chemical Safety Committee is pleased to announce it is accepting applications for the above project.

Risk assessments for foods, ingredients and additives have evolved over the past few decades to incorporate new techniques such as benchmark dose modeling. Additionally, risk assessment approaches have evolved to include thresholds of toxicological concern, and advancements in carcinogen risk assessment. While these advancements have enhanced the way in which health-based guidance values are derived, exposure assessments still tend to rely on deterministic approaches utilizing very conservative inputs. Deterministic assessments are easy to conduct and easy to interpret; however, as point estimates of exposure, they do not account for variability in the level and/or likelihood of occurrence of a chemical/contaminant or population differences in exposure inputs (e.g., food consumption amount and frequency). Probabilistic assessments can further refine deterministic assessments using distributions for various exposure inputs and, as such, better account for exposure variability and uncertainty.

Building from analysis of the current state of adoption of probabilistic exposure modeling by regulatory agencies to inform risk management decisions and regulation for food contaminants, this project will highlight the value of further integration of probabilistic exposure assessments into regulatory frameworks and discuss factors that hinder widespread adoption of probabilistic exposure models. Details and full instructions can be found in this RFP form.

Knowledge Mapping Opportunity: Metabolic and Physiological Effects of Fiber Sources for Children Across the Age Spectrum

The IAFNS Carbohydrates Committee is pleased to announce it is accepting applications for the above project.

The objective of this effort is to publish a qualitative scoping assessment on metabolic and physiological effects of added isolated or synthetic fibers among children from 1 to 18 years of age in order to identify evidence, research gaps and priority research needs, as well as determine whether there is sufficient evidence to conduct a quality systematic review on a specific added fiber and health outcome.

Proposal information is available here. Instructions for submissions can be found in this RFP form

Please submit pre-proposals by 11:59 pm Eastern Time on April 30, 2021 to Barbara Lyle at blyle@iafns.org

Protocol and Surrogate Validation for the Inactivation of Salmonella on Spices

Worldwide, spices are used to enhance the flavor of foods. In many cultures, spices are considered ready-to-eat and are added to foods after cooking, creating some risk for consumers if the spices have been contaminated with human pathogens. Several outbreaks of foodborne illness, associated with the consumption of spices have occurred; furthermore, numerous recalls of […]

Low-Calorie Sweeteners and Body Weight and Composition

Replacement of caloric sweeteners with lower- or no calorie alternatives may facilitate weight loss or weight maintenance by helping to reduce energy intake. However, past research examining the relationship between low-calorie sweeteners (LCSs) and body weight has produced mixed results. The aim of this study was to systematically review and quantitatively evaluate randomized controlled trials […]

This project focused on Toxicology and Risk Assessment of Chemical Mixtures. Institution: University of Cincinnati Summer Fellow: […]

Nutrition-Toxicity Interactions in Daphnia pulex: Developing an Alternative Model Organism for Early Life Exposures

As a well-known eco-toxicological model organism, Daphnia pulex may also offer advantages in human health research for assessing long-term effects of early life exposures to coupled stressors. This study will serve as a proof-of-concept for the use of Daphnia pulex as a screening model organism for long-term effects of exposure to multiple stressors in early […]

Future Research Needs Assessment for Fructose/Sugar and Health Outcomes

Forging an Understanding of the Double-Edged Iron Sword and Immunity

Upon infection, the host and pathogen compete to acquire, utilize and store essential iron. The goal of this project is to understand how iron nutrition contributes to infectious disease pathogenesis and clinical outcomes. This information can be utilized to determine how to best intervene in regions with high dual burdens of iron deficiency malnutrition and […]
