Background: Cardiorespiratory fitness is an integrative measure of cardiometabolic health and predictor of survival, yet little is known about its molecular underpinnings. Small molecule metabolites and lipids are increasingly recognized as exercise-stimulated signaling molecules and candidate molecular transducers of cardiorespiratory fitness.

Methods: We performed nontargeted liquid chromatography mass spectrometry-based plasma metabolomics in 654 participants (mean age, 35 years; 55% women) from the HERITAGE Family Study (Health, Risk Factors, Exercise Training, and Genetics) who had cardiorespiratory fitness (maximal oxygen uptake [VO2max]) measured by cardiopulmonary exercise testing and underwent 20 weeks of supervised endurance training. Metabolite-VO2max relationships were assessed using linear regression …

Association Between Ultraprocessed Food Consumption And Cardiovascular Disease Risk: Mesa (Multiethnic Study Of Atherosclerosis), Amier Haidar, Rishi Rikhi, Karol E Watson, Alexis C Wood, Michael D Shapiro

Children’s Nutrition Research Center Staff Publications

Background: Ultraprocessed foods (UPFs) have been linked to adverse cardiometabolic outcomes and increased atherosclerotic cardiovascular disease (CVD) (ASCVD) risk. However, prior research has largely focused on homogenous populations, lacking racial and ethnic diversity.

Objectives: The objectives are to examine the longitudinal relationship between UPF consumption and ASCVD risk and to investigate whether these associations differ by race/ethnicity, sex, or socioeconomic status.

Methods: The MESA (Multiethnic Study of Atherosclerosis) is a prospective cohort study of 6,814 U.S. adults aged 45 to 84 years, without clinically apparent CVD. UPF consumption was classified according to the Nova classification system. Multivariable cox proportional hazards …

Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey

UNH URC Open (2026 and after)

This project aims to identify low energy availability in a sample of collegiate athletes and explore the relationship with bone mineral density and nutrient deficiencies. Participants (n=3,407) were recruited from a northeast university and self-reported athlete status and physical activity via online questionnaire. Food records were used to calculate energy and nutrient intake. Anthropometrics including height, weight, body composition and bone mineral status were measured in duplicate. Energy availability (EA) was calculated as (Energy Intake (EI) -Exercising Energy Expenditure) (EEE)) /Fat Free Mass (FFM) (kg) and categorized as optimal (>45 kcal/kg FFM), subclinical, or clinically low (< 30 kcal/kg FFM). Fifteen percent of participants were characterized as athletes (club or division I varsity); mean EA was lower among athletes vs. nonathletes (17.90.7vs.21.90.3, p< .001). Males were more likely to have optimal EA status vs. females (8.8vs4.7%, p< .001). Most females (75.1%) were categorized as clinically LEA; 20.3% had subclinical LEA. Among men, athletes’ EA was similar to nonathletes (21.11.2vs22.20.5, p=.4); among females, athletes had lower EA vs. nonathletes (16.220.9vs21.70.3, p< .001). Males with clinically low EA were most likely to consume inadequate intakes of potassium, fiber, iron, and vitamin D (77.1,94.0,10.4 and 97.3%, respectively); similarly, females with clinically low EA, were most likely to consume inadequate intakes (81.9,87.6,88.3, and 99.5%, respectively). Bone z-scores were higher among athletes vs. non athletes (-.27±.06vs-.67±.02, p< .001) but were not different by EA status. Given the prevalence of LEA within the college athlete and nonathlete populations, further research and tailored nutritional education is needed for this at-risk population.

EVMS School of Health Professions Faculty Publications

Lifestyle intervention is critical for young adults with early-stage hypertension. A Western diet has negative effects on kidney function and blood pressure; however, time-of-day effects are understudied. We hypothesized that consumption of a Western-style meal that is misaligned with the endogenous circadian rhythm would have adverse effects on blood pressure, kidney function, and vascular function. Ten young adults with elevated blood pressure or stage 1 hypertension (means ± SD: 26 ± 8 yr, 50% female) underwent a randomized crossover, isocaloric controlled feeding intervention. Participants were allocated to receive a Western-style meal high in sodium, sugar, and saturated fat in the …

Nutrition epidemiological models involve many analytic decisions, such as defining exposures, selecting which covariates to include, or configuring variables in different ways. We explored the impact of analytical decisions on conclusions in nutrition epidemiology using self-reported beef intake and incident coronary heart disease as a case study. We used REasons for Geographic and Racial Differences in Stroke (REGARDS) data, and selected covariates and their configurations from published literature to recapitulate common models used to assess associations between meat intake and health outcomes. Three model sets were designed: sets one and two used continuous and quintile-defined beef intakes, respectively, each with …

The Impact Of Gastric Sleeve And Roux-En-Y Gastric Bypass On Chief Cell Function And Protein Digestion In Obese Patients, Garikoitz Mikel Gainza

Honors Undergraduate Theses

Obesity has become one of the largest global health concerns of the 21^st century, correlating with numerous associated diseases. To help address the growing prevalence and burden of obesity, sleeve gastrectomy and Roux-en-Y gastric bypass have become two commonly performed surgical procedures done to promote weight loss by altering the anatomical structure of the stomach and surrounding organs of the gastrointestinal system. Although the benefits of improved metabolism linked to these surgical procedures are well studied, their impact on the physiology of gastric cells, and more specifically chief cells as they relate to protein digestion post-surgery, is yet to …

Comparing Perceived Ideal Protein Intake In Plant-Based Versus Meat-Based Diet Consumers, Gysel Avendano, Saya Iwanaga

Loma Linda University Research Reports

High-protein diets have gained significant popularity in both social media and public discussion and more recently, a significant rise in protein consumption has been observed. Existing research has reported differences in actual protein intake across dietary patterns, with animal-based diets generally associated with higher total protein intake compared to plant-based diets. This growing focus on protein raises important questions about perceived ideal protein intake and the factors that shape it.

The primary objective is to compare perceived ideal protein intake among Southern California adults consuming meat-based versus plant-based diets. Additionally, we explored the influence of protein-related knowledge, beliefs, values, information …
