Department of Nutrition and Health Sciences: Faculty Publications

The goal of the Food website was to develop Internet-based content that was relevant and reached the general public and multiplier groups, such as educators, health professionals, and media outlets. The purpose of this paper was to examine whether a multi-modal approach to information delivery through increases in and changes to content, electronic mailing list creation, and social media posting impacted user access, traffic channels, and referrals from 2010 to 2014. When comparing 2010-2011 versus 2013-2014, there was a 150% increase in total pageviews, 197% increase in unique pageviews, and a 39% increase in average time spent on a page. …

Food Labeling And Consumer Associations With Health, Safety, And Environment, Joanna K. Sax, Neal Doran

Faculty Scholarship

The food supply is complicated and consumers are increasingly calling for labeling on food to be more informative. In particular, consumers are asking for the labeling of genetically modified organisms (GMO) food based on health, safety and environmental concerns. At issue is whether the labels that are sought would accurately provide the information desired. The present study examined consumer (n = 181) perceptions of health, safety and the environment for foods labeled organic, natural, fat free or low fat, GMO, or non-GMO. Findings indicated that respondents consistently believed that foods labeled GMO are less healthy, safe and environmentally-friendly compared to …

Effect Of Maternal Diet On Select Fecal Bacteria In Mares And Their Foals, Morgan Brewer Pyles

Theses and Dissertations--Animal and Food Sciences

The process of microbial colonization in the gastrointestinal tract of foals and the factors influencing this process are not well understood. The objectives were to determine the effect of starch source in pelleted concentrates in the maternal diet on select fecal bacterial groups in mares and their foals and to evaluate changes in these bacterial groups over time. Thoroughbred foals (n=19) were from dams fed one of two concentrates: an oat-based (OB) or corn and wheat middling-based (CWB) pelleted concentrate. Fecal samples were collected from mares at 324 d of gestation, pre-foaling, 1 d, 14 d, and 28 d after …

The Influence Of Time On Food Intake Patterns: Age, Period, Cohort Differences, Karina L. Christopher

Theses and Dissertations--Gerontology

The impact of diet and exercise on overall health and chronic disease risk has been well examined. Multiple studies show that Americans eat more now than they did fifty years ago. What isn’t known is how much of an impact time has on food intake patterns of individuals in terms of different age groups, historic periods of structural influences, and birth cohorts.

In order to identify the impact of time on food intake this study examined time from multiple perspectives. The first aim of this study was to determine food intake patterns among age groups across five time periods using …

Genotoxic Effects Of Magnesium Deficiency In The Cardiovascular System And Their Relationships To Cardiovascular Diseases And Atherogenesis, Burton M. Altura, Nilank C. Shah, Gatha J. Shah, Bella T. Altura

The School of Health Sciences Publications and Research

The authors present evidence for a novel, new hypothesis whereby magnesium deficiency (MgD) acts as a genotoxic agent which probably causes numerous, hertofore, unrecognized consequences, even over a short-term, on the physiological, molecular and biochemical machinery of cardiovascular tissues and cells. The end result of these genotoxic effects of MgD probably plays important roles in the etiology and generation of diverse cardiovascular diseases, atherosclerosis, inflammation, and strokes via alterations in the epigenome of cardiovascular tissues and cells. The importance of adequate water-borne and dietary levels of Mg is emphasized.

The Expression Of Platelet-Activating Factor Is Induced By Low Extracellular Mg2+ In Aortic, Cerebral And Neonatal Coronary Vascular Smooth Muscle; Cross Talk With Ceramide Production, Nf–Kb And Proto-Oncogenes: Possible Links To Atherogenesis And Sudden Cardiac Death In Children And Infants, And Aging: Hypothesis, Review And Viewpoint, Burton M. Altura, Wenyan Li, Aimin Zhang, Tao Zheng, Nilank C. Shah, Gatha J. Shah, Bella T. Altura

The School of Health Sciences Publications and Research

An attempt is made, herein, to reconcile, and integrate, various phenomena associated with magnesium deficiency (MgD) in cardiovascular health, disease, and aging as well as reasons for the high incidence of sudden cardiac death in infants and young adults. With new experiments, we demonstrate, for the first time, that very low concentrations of platelet-activating factor (PAF), when added to primary cultured cerebral, neonatal coronary, and aortic vascular smooth muscle (VSM) cells (from three different mammals) promote rapid rises in free intracellular Ca2+ ions and a significant, concomitant reduction in free intracellular Mg2+ ions; these actions of PAF being curtailed with …

Potential Roles Of Magnesium Deficiency In Inflammation And Atherogenesis: Importance And Cross-Talk Of Platelet-Activating Factor And Ceramide, Burton M. Altura, Asefa Gebrewold, Nilank C. Shah, Gatha J. Shah, Bella T. Altura

The School of Health Sciences Publications and Research

Epidemiologic studies in North America and Europe have shown that people consuming Western-type diets are low in magnesium (Mg) content (i.e., < 30 - 65% of the RDA for Mg); most such diets in the USA show that 60 - 80% of Americans are consuming only 185 - 235 mg/day of Mg. Low Mg content in areas of soft-water, and Mg-poor soil, is associated with high incidences of ischemic heart disease (IHD), coronary artery disease, hypertension, and sudden cardiac death (SCD). It is clear that the leading underlying cause of death worldwide is atherosclerosis. Importantly, both animal and human studies have shown an inverse relationship between dietary intake of Mg and atherosclerosis. The myocardial level of Mg has consistently been observed to be lower in subjects dying from IHD and SCD in soft-water areas than those in hard-water areas. Over the past 20 years, our laboratories, using several types of primary cultured vascular smooth muscle (VSM) cells, and myocardial cells, demonstrated that declining levels of extracellular Mg ([Mg2+]0) activated several enzymatic pathways to produce increases in cellular sphingolipids, particularly ceramides which are known to exert numerous types of cardiovascular manifestations including inflammatory effects; the latter play important roles in atherogenesis and cardiovascular diseases. Approximately 20 years ago, we reported that low [Mg2+]0 caused formation of platelet-activating factor (PAF) as well as other types of PAF-like molecules and suggested that these molecules might be causative agents in low Mg2+- induced IHD and SCD. Herein, we review results and data from our labs which strongly support roles for ceramides, PAF and PAF-like lipids in low [Mg2+]0-induced IHD and SCD.

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias, Brianna L. Neumann, Charlayne Mitchell, Jamie I. Baum

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Over 30% of adults in the U.S. are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) rather than carbohydrate (CHO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n = 4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in a randomized, crossover design study with a one-week washout period (time between the administration …

Successful Weight Management: Barriers And Facilitators To Maintaining Weight After Weight Loss Via A Meal Replacement Program, Hope D. Kleine

Electronic Theses and Dissertations

Purpose: Meal replacement programs (MRPs) facilitate weight loss. Unfortunately, a large percentage of individuals that lose weight through MRP are not successful at maintaining their weight. Weight regain one year following weight loss via meal replacements has been as high as 40-50%, demonstrating a critical need to improve weight maintenance in MRP participants. Therefore, the purpose of this study is to identify barriers and facilitators of weight maintenance after reaching a goal weight in MRP participants.

Methods: Seven focus groups of ≤8 clients were conducted to discuss barriers and facilitators of weight maintenance prior to reaching a point of …

The Healthfulness Of Entrées And Students’ Purchases In The Campus Dining Environment, Krista Leischner

The purpose of this study is to determine the availability of “more” versus “less healthful” entrée items in the campus dining environment and also to determine if students’ purchases are reflective of what is offered.
Entrée items were categorized as either “more” or “less healthful” according to the American Heart Association guidelines. Students’ entrée purchases from the 2014- 2015 school year were analyzed at a Midwestern university. The relationship between students’ demographics and food purchases was also analyzed in this observational study. Significant differences between more healthful and less healthful purchased and available items were determined using a Chi-square test. …

Differences In Running Mechanics Between Overweight/Obese And Healthy Weight Children, Kristen Roles

Electronic Theses and Dissertations

Background/Purpose: Physical activity is commonly prescribed to reduce childhood obesity. However, due to differences in mechanics during low-impact activities, such as walking, obese children may be more prone to negative physical complications during high-impact activities, such as running. Therefore, this study analyzed the mechanical differences in running mechanics between healthy weight (HW) and overweight/obese (OV/OB) children. We hypothesized that when compared to HW children, OV/OB children would display higher vertical loading, greater joint moments and greater joint angular impulses during running. We also expect decreased sagittal plane range of motion and increased frontal plane range of motion of the hip, …

Relationships Between Behavioral Measures And Productivity In Finishing Beef Cattle, Jasmyn Mimiko

Theses and Dissertations--Animal and Food Sciences

The relationship between measures of temperament, growth performance, and social hierarchy in finishing beef cattle were explored in two experiments. In experiment 1, high OCS (objective chute score) steers had periods of significantly higher ADG (P < 0.01), but OCS had no relationship with dominance ranking (P > 0.47). Conversely, slow exit velocity (EV) correlated with higher ranking (P ≤ 0.06), but EV had no relationship with performance (P > 0.37) in a competitive environment. Rank showed no relationship with performance (P > .58). In experiment 2, steers with fast EV had periods of decreased growth (P ≤ .06), intake (P ≤ .06), and gain:feed (G:F; P = 0.02). There were no interactions between …

Postprandial Paraoxonase 1 Activity Following Consumption Of Recommended Amounts Of Mixed Meals In Healthy Males, Noriko Kameyama, Chizuko Maruyama, Kazuhiko Kotani, Russell Caccavello, Alejandro Gugliucci, Sadako Matsui, Taro Maruyama

Faculty Publications & Research of the TUC College of Osteopathic Medicine

Aim: Postprandial lipid level increases induce oxidative stress, which is involved in atherogenesis. The antioxidant properties of paraoxonase 1 (PON1) have attracted attention. However, changes in postprandial PON1 levels differ across prior studies, and changes in PON1 lactonase activity, potentially relevant to PON1 physiology, after the consumption of ordinary meals are unknown. Herein we evaluated postprandial serum lipid levels and PON1 changes following mixed-meal consumption of the amounts recommended for ordinary meals.
Methods: Nine healthy male volunteers consumed three different meals in a randomized cross-over design. The test meals were as follows: S, white rice; SMF, S with …
