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 …

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 …

Examining The Best Dietary And Lifestyle Interventions To Prevent Hyperinsulinemia And Insulin Resistance In Women With Polycystic Ovarian Syndrome, Erica C. Morman

Honors Undergraduate Theses

Polycystic Ovarian Syndrome (PCOS) is a complex reproductive and metabolic disorder that affects up to 15% of women, contributing to insulin resistance, hyperinsulinemia, risk for developing type 2 diabetes. The interconnected hormonal and metabolic disruptions in PCOS create a feedback loop that exacerbates symptoms, making dietary and exercise interventions critical in its management. This literature review evaluates the efficacy of various dietary interventions including the ketogenic diet, high-protein diet, low-carbohydrate diet, and high-fiber diet, as well as exercise interventions such as high-intensity interval training (HIIT), resistance training, and moderate-intensity aerobic exercise. Results found that modifying carbohydrate intake, and increasing fiber …

A Systematic Review Of Dietary Trends, Influencing Factors, And Their Impacts On Cardiovascular Health In Turkish Populations, Pelin L. Özoğlu

Honors Undergraduate Theses

Cardiovascular disease (CVD) is the leading cause of death globally, including in Türkiye. One key factor influencing CVD prevention is dietary patterns, which directly impacts cardiovascular health. Türkiye traditionally follows the Mediterranean diet (MedDiet), which is acclaimed for its cardiovascular benefits. Despite this, Türkiye continues to experience high rates of CVD, with projections indicating that CVD mortality will double for both men and women by 2030. It is crucial to address diet-related factors, including potential nutritional deficiencies, to reduce cardiovascular health risks.

This research aims to analyze the Turkish community's adherence to the Mediterranean diet to understand why CVD prevalence …

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 …

A Reflection-Spectroscopy Measured Skin Carotenoid Score Strongly Correlates With Plasma Concentrations Of All Major Dietary Carotenoid Species Except For Lycopene, Qiang Wu, Cheryl Webb Cherry, Stephanie Jilcott Pitts, Melissa N Laska, Neal Craft, Nancy E Moran

Children’s Nutrition Research Center Staff Publications

Skin carotenoids can be measured non-invasively using spectroscopy methods to provide a biomarker of total dietary carotenoid and carotenoid-rich fruit and vegetable intake. However, the degree to which skin carotenoid biomarkers reflect intakes of specific carotenoids must be determined for specific devices. Previously, findings were mixed regarding the correlation between reflection spectroscopy (RS)-assessed skin carotenoids and individual plasma carotenoid concentrations. The current study expands on prior analyses to examine the cross-sectional associations between adult RS-assessed skin carotenoids and individual carotenoid species intakes and plasma concentrations, controlling for potential covariates. We hypothesized that RS-assessed skin carotenoid scores would strongly correlate with …
