2022-2023 Seminar Schedule

September 21, 2022
Defining the Public Health Threat of Dietary Supplement Fraudexternal link disclaimer
John W. Spink, Ph.D.—School of Packaging, Michigan State University, Lansing, MI
Product fraud is a longstanding issue that can now include counterfeit and substandard medicines. In 2018 the food industry implemented compliance requirements to assess and prevent food fraud. Dietary supplements often fall into a gap between medicines and foods. In this presentation, Dr. Spink reviewed observed types of dietary supplement fraud and discussed implementation of strategies to prevent them.

October 12, 2022 
Exploring Compound Interactions in Botanical Supplements using NP Analystexternal link disclaimer
Roger G. Linington, Ph.D.—Simon Fraser University, Burnaby, BC, Canada

Despite rapid advances in analytical chemistry hardware and software, determining the accurate chemical composition of complex mixtures, such as botanical extracts, remains a significant challenge. Integrating chemical and biological information on complex mixtures is similarly challenging, particularly when multiple bioactive components are present in a single mixture. In this talk, Dr. Linington presented his program’s NP Analyst (www.npanalyst.orgexternal link disclaimer), an online, open access data integration platform that is designed to connect chemical and biological fingerprints of complex mixtures. The design, theory, and applications of this new platform were discussed along with the opportunities and challenges associated with large-scale data integration methods in natural products and botanicals research.

November 2, 2022
Patient Nutrition and the Electronic Health Recordexternal link disclaimer
Sandra W. Citty, Ph.D., ARNP-BC, CNE—Department of Family and Community Health Systems, University of Florida College of Nursing and North Florida South Georgia Veterans Health System, Geriatrics Research Education Clinical Center (GRECC), Gainesville, FL
As many as 50% of hospitalized older adults are malnourished or require additional nutrition support therapies to meet their nutrition needs during their hospitalization. Although there have been advances in both the knowledge and application of effective nutritional therapies for acutely and critically ill hospitalized patients, significant gaps and barriers in the electronic health record and related process/workflow remain. These gaps in nutritional care put the patient at risk. Optimization of the electronic health record and related workflows for nutrition therapies in hospitals is needed to improve safety, accuracy, transparency, and quality of nutrition care. In this talk, Dr. Citty discussed examples of barriers to optimal nutrition care and strategies to improve the end-user experience and functionality of the electronic health record to support effective nutrition care for hospitalized patients.

December 14, 2022, 11:00 a.m. (ET)
The Use of Comparative Nutrigenomics to Select Human-relevant Animal Modelsexternal link disclaimer
Harry Dawson, Ph.D.—Research Chemist, Nutritionist; Diet, Genomics and Immunology Laboratory; Agricultural Research Service (ARS), U.S. Department of Agriculture (USDA)
A large-scale analysis of genes related to nutrition and metabolism reveals that pigs have roughly fourfold fewer unique genes than the mouse or human. When a gene is missing from one or more genomes the frequency and similarity of gene preservation between pigs and humans is high; however, notable differences were found between humans and pigs in genes encoding digestive enzymes and nutrient sensing genes. This talk will focus on the relevance of this analysis in the selection of animal models.

January 11, 2023, 11:00 a.m. (ET)
Small-Quantity Lipid-Based Nutrient Supplements for the Prevention of Child Malnutritionexternal link disclaimer
Kathryn Dewey, Ph.D.—Distinguished Professor Emerita, Department of Nutrition, Institute for Global Nutrition, University of California, Davis, CA
Small-quantity lipid-based nutrient supplements (SQ-LNS) were designed to provide multiple micronutrients within a food base that also provides energy, protein, and essential fatty acids, targeted towards preventing malnutrition in vulnerable populations in low- and middle-income countries. In this talk, Dr. Dewey will discuss the physical, cognitive, motor, and emotional progress of sample populations who have received SQ-LNS, as well as the efforts underway to scale-up this intervention within coordinated strategies to improve child survival, prevent child malnutrition, and promote healthy development.

January 25, 2023, 11:00 a.m. (ET)
Aging – Immunology - DO-HEALTHexternal link disclaimer
Heike Bischoff-Ferrari, Prof. Dr. med., Dr. PH—University of Zurich, Zurich, Switzerland
The seminar held by Prof. Bischoff-Ferrari will introduce the DO-HEALTH trial, a 2x2x2 factorial design 3-year clinical trial in 2157 generally healthy adults age 70 and older from five European countries. The three treatments tested in DO-HEALTH were vitamin D (2000 IU/day), omega-3 fats (1 g/day) and a simple home exercise program (3x 30 min /week). With a focus on aging and immunology, the seminar will discuss DO-HEALTH findings on infections, incident cancer and incident frailty.

February 8, 2023, 11:00 a.m. (ET)
Diet and the Microbiome: An Ecological and Evolutionary Biology Perspectiveexternal link disclaimer
Aspen T. Reese, Ph.D.—University of California, San Diego, San Diego, CA
Diet is a primary driver of gut microbial composition, but to date we remain limited in our ability to use dietary manipulations to alter the microbiome or its functioning. Key insights from evolution and ecology can help explain this shortcoming and provide direction for future research.

March 1, 2023, 11:00 a.m. (ET)
Food Politics 2023: Supplements, Diet, Food Systemsexternal link disclaimer
Marion Nestle, Ph.D.—New York University, New York, NY 
Evaluating the quality—the truth—of information given to the public about diet, nutrition, and health has become a major challenge for food and nutrition scientists, educators, and regulators. Publicly available information about supplements is a classic example of this problem as so much of this information is based on anecdote, belief, and opinion rather than on experimental evidence, such as from clinical trials. The literature on countering misinformation tends to focus on providing facts, despite limited evidence for the effectiveness of this strategy. This presentation will address the dilemma of providing actionable information and countering misinformation from the perspectives of its research base and the speaker’s personal experience and views. 

April 19, 2023, 11:00 a.m. (ET)
Anemia and the Anemia Task Force
Dan Raiten, Ph.D.—National Institute of Child Health and Human Development (NICHD), National Institutes of Health (NIH), Bethesda, MD
