Department of Medicine Faculty Publications

Type 1 diabetes (T1D), a leading cause of mortality in the United States, is associated with heart disease, nephropathy, neuropathy, retinopathy, and stroke. While management of T1D with medications and healthy lifestyle choices is critical, recent research highlights the contributory role of environmental diabetogens in the pathogenesis of T1D. Here, we propose that the furan compound, 5-hydroxymethyl-2-furfural (HMF), which forms when hexoses such as glucose or fructose lose three water molecules during thermal food processing, might be an unrecognized dietary diabetogen. HMF is a suspected mutagen and carcinogen. In a previous experiment in the rat 832/13 beta-cell line, when cultures …

High Diversity Of Dietary Flavonoid Intake Is Associated With A Lower Risk Of All-Cause Mortality And Major Chronic Diseases, Benjamin H. Parmenter, Alysha S. Thompson, Nicola P. Bondonno, Amy Jennings, Kevin Murray, Aurora Perez-Cornago, Jonathan M. Hodgson, Anna Tresserra-Rimbau, Tilman Kühn, Aedín Cassidy

Research outputs 2022 to 2026

Higher habitual intakes of dietary flavonoids have been linked with a lower risk of all-cause mortality and major chronic disease. Yet, the contribution of diversity of flavonoid intake to health outcomes remains to be investigated. Here, using a cohort of 124,805 UK Biobank participants, we show that participants who consumed the widest diversity of dietary flavonoids, flavonoid-rich foods and/or specific flavonoid subclasses had a 6–20% significantly lower risk of all-cause mortality and incidence of cardiovascular disease, type 2 diabetes, cancer, respiratory disease and neurodegenerative disease. Furthermore, we report that both quantity and diversity of flavonoids are independent predictors of mortality …

James, Paul Aveyard, Helen Mitchell, Jacquie Garton-Smith, Megan E. Rollo, Chloe Maxwell-Smith, Amira Hassan, Hayley Breare, Lucy M. Butcher, Christina M. Pollard

Research outputs 2022 to 2026

Background: Almost a third of Australian adults are living with obesity, yet most cannot access medical nutrition therapy from dietitians, that is, the health professionals trained in dietary weight management services. Across the health system, primary care doctors readily identify people who may benefit from weight management services, but there are limited referral options in the community. Dietitians are trained to provide evidence-informed dietary treatment of overweight and obesity but are underutilized and underresourced. The chat2 (Connecting Health and Technology 2) trial will test combining new technologies for dietary assessment with behavior change techniques to improve outcomes for people living …

Exploring Associations Between Personality Type & Fruit And Vegetable Consumption, Allison Woldt, Tanya Mora, Liang Ji, Julie Jones, Jeje Noval

Loma Linda University Research Reports

Fruit and vegetable intake is vital for preserving health and avoiding chronic illnesses, yet only approximately 1 in 10 adults in the U. S. adhere to daily consumption guidelines, based on CDC data. While earlier research has examined external factors such as socioeconomic status, cultural influences, and religion as significant determinants of dietary habits, new studies highlight a crucial internal element: personality. Our research delves into this emerging area by examining the connection between personality types, derived from the Myers-Briggs Type Indicator (MBTI), and fruit and vegetable (FV) consumption. In contrast to the extensively studied Big Five personality framework, the …

A Comprehensive Uhplc-Ms/Ms And Extraction Method Reveals Flavonoid Profile And Concentration Are Diverse In Spinach (Spinacia Oleracea L), Michael P Dzakovich, Elaine A Le, Alvin L Tak, Shaji K Chacko

Children’s Nutrition Research Center Staff Publications

INTRODUCTION: Spinach produces an array of unique flavonoids not commonly found in other fruits and vegetables. These molecules likely serve as defense agents against biotic and abiotic stress and may have health beneficial properties for humans. Current methods to analyze spinach flavonoids are incomplete and only capture a portion of this uncharacterized pathway. A comprehensive analysis method is needed to determine how genetics, environmental conditions, and other factors influence spinach flavonoid biosynthesis.

METHODS: We developed and validated a high-throughput extraction and ultra high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method to separate and quantify 39 spinach flavonoid species in 11.5 …

New Genetic Tools To Define The Pathophysiology Of Inborn Errors Of Cobalamin Metabolism Impacting Mammalian Development, Tiffany Chern, Xuefei Tong, William G Bauer, David J Quispe-Parra, Xia Gao, Kamryn N Gerner-Mauro, Ross A Poché

Children’s Nutrition Research Center Staff Publications

The congenital, autosomal recessive disorder combined methylmalonic acidemia and homocystinuria - cblC type, is the most common inborn error of cobalamin (vitamin B12) metabolism. In its early onset form, cblC profoundly impacts fetal development of the central nervous system, hematopoietic system, and other tissues. Previously, mutations in the MMACHC gene, which encodes a protein required for the intracellular trafficking and enzymatic processing of free cobalamin into active coenzyme forms, were found to cause cblC. These coenzymes are required in two metabolic pathways which produce either succinyl-CoA in the mitochondria or methionine in the cytosol. However, due to a lack of …

Characterizing Fermentable Carbohydrate Foods In The Diets Of Children With Abdominal Pain-Related Disorders Of Gut-Brain Interaction And Healthy Children, Vishnu Narayana, Jocelyn Chang, Ann R Mcmeans, Tasha Murphy, Rona L Levy, Robert J Shulman, Bruno P Chumpitazi

Children’s Nutrition Research Center Staff Publications

Objectives: Restricting dietary fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) can alleviate symptoms in children with disorders of gut-brain interaction (DGBI). Due to the restrictions of a low FODMAP diet (LFD), a less restrictive FODMAP Gentle diet (FGD) has been suggested. However, the types and amounts of high FODMAP foods and carbohydrates commonly consumed by children have not been studied. We aimed to identify the high FODMAP foods and proportions of FODMAP carbohydrates consumed by children with DGBI and healthy children (HC) and to determine which usually ingested FODMAPs would be restricted on the FGD.

Methods: Three-day diet records from …

Health Sciences Faculty Publications

In resource-limited areas, where accurate weight-for-height Z-scores are hard to obtain, Mid-Upper Arm Circumference (MUAC) is a simple tool to identify wasted children. MUAC alone, however, may miss identification of many wasted children, leading to untimely intervention and potentially death. Our study aimed to identify the best-performing case definition to detect wasting by Weight-for-Height z-scores (WHZ) in Filipino children aged 6-59 months. We analyzed the 2018-2019 Expanded National Nutrition Survey to assess the diagnostic performance of MUAC cutoffs and a case definition combining MUAC and weight-for-age z-score (WAZ) in identifying moderate and severe wasting compared to the WHZ criterion. The …
