Department of Nutrition and Health Sciences: Faculty Publications

We examined the neuromuscular adaptations following 3 and 6 weeks of 80 vs. 30%one repetition maximum (1RM) resistance training to failure in the leg extensors. Twenty-six men (age = 23.1 ± 4.7 years) were randomly assigned to a high- (80% 1RM; n = 13) or low-load (30% 1RM; n = 13) resistance training group and completed leg extension resistance training to failure 3 times per week for 6 weeks. Testing was completed at baseline, 3, and 6 weeks of training. During each testing session, ultrasound muscle thickness and echo intensity, 1RM strength, maximal voluntary isometric contraction (MVIC) strength, and contractile …

Association Between Energy Balance And Metabolic Hormone Suppression During Ultra-Endurance Exercise, Bjoern Geesmann, Jenna C. Gibbs, Joachim Mester, Karsten Koehler

Department of Nutrition and Health Sciences: Faculty Publications

Ultra-endurance athletes often accumulate an energy deficit when engaging in ultra-endurance exercise, and upon completion of the exercise, they exhibit endocrine changes that are reminiscent of starvation. However, it remains unclear whether these endocrine changes are a result of the exercise per se or secondary to the energy deficit, and more importantly, whether these changes can be attenuated by increased dietary intake. Our goal was to assess the relationship between changes in key metabolic hormones following ultra-endurance exercise and measures of energy balance. Metabolic hormones as well as energy intake and expenditure were assessed in 14 well-trained male cyclists who …

Prebiotics And Inflammatory Bowel Disease, Heather Rasmussen, Bruce R. Hamaker

Department of Nutrition and Health Sciences: Faculty Publications

Inflammatory bowel disease risk factors include poor diet, and corresponding low intake of dietary fiber, specifically prebiotics, which is fermented by the gut microbiota. Dietary fibers, many of which are potential prebiotics, have hundreds to thousands of unique chemical structures that may promote bacteria or bacterial groups to provide beneficial health effects. In vitro and in vivo animal models provide some support for the use of prebiotics for inflammatory bowel disease through inflammation reduction. Studies using prebiotics in patients with inflammatory bowel disease are limited and focus on only a select few prebiotic substances.

Keywords: Inflammatory bowel disease, Ulcerative colitis, …

Hepatocyte Abca1 Deletion Impairs Liver Insulin Signaling And Lipogenesis, Chia-Chi C. Key, Mingxia Liu, C. Lisa Kurtz, Soonkyu Chung, Elena Boudyguina, Timothy A. Dinh, Alexander Bashore, Peter E. Phelan, Barry I. Freedman, Timothy F. Osborne, Xuewei Zhu, Lijun Ma, Praveen Sethupathy, Sudha B. Biddinger, John S. Parks

Department of Nutrition and Health Sciences: Faculty Publications

Plasma membrane (PM) free cholesterol (FC) is emerging as an important modulator of signal transduction. Here, we show that hepatocyte-specific knockout (HSKO) of the cellular FC exporter, ATPbinding cassette transporter A1 (ABCA1), leads to decreased PM FC content and defective trafficking of lysosomal FC to the PM. Compared with controls, chow-fed HSKO mice had reduced hepatic (1) insulin- stimulated Akt phosphorylation, (2) activation of the lipogenic transcription factor Sterol Regulatory Element Binding Protein (SREBP)-1c, and (3) lipogenic gene expression. Consequently, Westerntype diet-fed HSKO mice were protected from steatosis. Surprisingly, HSKO mice had intact glucose metabolism; they showed normal gluconeogenic gene …

Characterizing Food Insecurity At A Northeast Land-Grant University, Alana Ruth Davidson

Honors Theses and Capstones

In 2015, 15.8 million U.S. households were food insecure. While nationally food insecurity is assessed at the household and childhood level, university students are not explicitly monitored. The purpose of this study was to determine the prevalence of food insecurity at a northeast land grant university and characterize the contributing factors. A pilot study (n=211) was conducted in fall 2014 among a general nutrition class and found that 12.4% of students were food insecure, with another 5.7% reported marginal food security. A larger, university wide survey among graduate and undergraduate students was conducted in fall 2015 (n=943) and found that …

Connecting Culturally And Spiritually To Healthy Eating: A Community Assessment With Native Hawaiians, Mary Frances Oneha, Joan Dodgson, Mabel Ho`Oipo Decambra, Carol Titcomb, Rachelle Enos, Sandie Morimoto-Ching

Asian/Pacific Island Nursing Journal

Many of the chronic illnesses disproportionately experienced by Native Hawaiians are directly related to poor diets and long-standing obesity beginning in childhood. We report on the findings of in-depth key informant interviews (N = 14) that took place in two Native Hawaiian communities as part of a larger, community-based participatory research study that included a community assessment through individual interviews and focused group discussions, and a pilot intervention targeting pregnant women, their infants, and families. Four categories emerged from the qualitative analysis of interview transcripts that described an understanding of “healthy eating”: family roles and responsibilities, aspects of community …

Cardiorespiratory Fitness Is Associated With Better Executive Function In Young Women, Samuel P. Scott, Mary Jane De Souza, Karsten Koehler, Dylan L. Petkus, Laura E. Murray-Kolb

Department of Nutrition and Health Sciences: Faculty Publications

Purpose: A positive association between cardiorespiratory fitness (CRF) and cognitive function has been demonstrated mainly in children and older adults. Women attending college live in a cognitively demanding setting where optimal cognition matters but often experience declines in CRF. Our aim was to test whether CRF is associated with executive function in young adult women.

Methods: Participants in this cross-sectional study included 120 healthy women age 18–35 yr in a university setting. Each woman completed a maximal treadmill-based exercise test to determine peak oxygen uptake (V˙O_2peak), computerized tests of executive function, and questionnaires to assess motivation …

Eicosapentaenoic Acid Potentiates Brown Thermogenesis Through Ffar4-Dependent Up-Regulation Of Mir-30b And Mir-378*, Jiyoung Kim, Meshail Okla, Anjeza Erickson, Timothy P. Carr, Sathish Kumar Natarajan, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Emerging evidence suggests that n-3 polyunsaturated fatty acids (PUFA) promote brown adipose tissue thermogenesis. However, the underlying mechanisms remain elusive. Here, we hypothesize that n-3 PUFA promotes brown adipogenesis by modulating miRNAs. To test this hypothesis, murine brown preadipocytes were induced to differentiate the fatty acids of palmitic, oleate, or eicosapentaenoic acid (EPA). The increases of brown-specific signature genes and oxygen consumption rate by EPA were concurrent with up-regulation of miR-30b and 378 but not by oleate or palmitic acid. Next, we hypothesize that free fatty acid receptor 4 (Ffar4), a functional receptor for n-3 PUFA, modulates …

Vegetarian Versus Meat-Based Diets For Companion Animals, Andrew Knight, Madelaine Leitsberger

Nutrition Collection

Companion animal owners are increasingly concerned about the links between degenerative health conditions, farm animal welfare problems, environmental degradation, fertilizers and herbicides, climate change, and causative factors; such as animal farming and the consumption of animal products. Accordingly, many owners are increasingly interested in vegetarian diets for themselves and their companion animals. However, are vegetarian canine and feline diets nutritious and safe? Four studies assessing the nutritional soundness of these diets were reviewed, and manufacturer responses to the most recent studies are provided. Additional reviewed studies examined the nutritional soundness of commercial meat-based diets and the health status of cats …

Decomposing Trends In Adult Body Mass Index, Obesity, And Morbid Obesity, 1971-2012, Ashley Wendell Kranjac, Robert L. Wagmiller

Sociology Faculty Articles and Research

Trends in adult obesity have been used to motivate key public health policies in the United States. While these analyses provide important insights into the broad historical contours of the obesity epidemic in the U.S., they shed less light on the proximate mechanisms that have generated these changes and that will ultimately determine the long-term course and pace of change in obesity rates. We used data from the National Health and Nutrition Examination Survey (NHANES), Glenn Firebaugh's linear decomposition technique, and Kitagawa's algebraic decomposition method to decompose change in body mass index (BMI), obesity, and morbid obesity from 1971 through …

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Purpose: This study aims to explore the correlation between students’ self-perception of body image and FITNESSGRAM scores, the relationship between children’s body perceptions and their actual body mass index (BMI), and to see if body image in children affects their physical activity level.

Methods: FITNESSGRAM fitness testing protocol and a survey developed for the KidQuest nutrition intervention program by South Dakota State University (SDSU) was used to assess the correlation between students’ (n= 319) self-perception of body image and FITNESSGRAM scores. In addition accelerometers were used to assess the physical activity level of a subsample (n=57) of the …

Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Black beans contain high phenolic contents that are considered potent antioxidants. Relatively little is known about their ability to inhibit the carbohydrate-hydrolyzing enzymes α-amylase and α-glucosidase from releasing glucose from starch and/or disaccharides. The objective of this project was to determine the optimum procedures for extracting total phenols (TP), total flavonoids (TF) and total condensed tannins (TCT) from black beans (Phaseolus vulgaris), and then to determine the ability of the phenolic rich extracts to inhibit α-amylase and α-glucosidase. Due to their high phenolic levels, it was hypothesized that black beans would be an effective inhibitor of α-amylase and α-glucosidase, which …

Exploration Of Malnutrition Coding Practices At Nebraska Medicine, Frances C. Becker

Theses & Dissertations

Background: Malnutrition is present in 25-50% of hospitalized patients. Patients identified as malnourished are assigned a code based on the type and severity of malnutrition in order to gain the necessary reimbursement to care for the patients. There is a current gap in the research regarding the characteristics that define the difference between malnourished patients classified with a major complications and comorbidities (MCC) code versus a complications and comorbidities (CC) code.

Purpose: The purpose of this study was to determine which malnutrition codes are being used at Nebraska Medicine. Additionally, this study obtained clinical factors that are associated with malnutrition …

A Low-Carbohydrate Ketogenic Diet Combined With Six Weeks Of Crossfit Training Improves Body Composition And Performance, Rachel M. Gregory

Masters Theses, 2010-2019

CrossFit is a high-intensity power training (HIPT) type exercise for all levels of age and fitness that has gained recognition as one of the fasting growing sports in America. No previous research has been found which examines body composition changes or performance in individuals consuming a LCKD and participating in CrossFit training. PURPOSE: The purpose of this research was to examine the effects of a 6-week LCKD and CrossFit program on body composition and performance. METHODS: Twenty-seven non-elite CrossFit subjects (mean ± SD age = …

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias

Human Nutrition and Hospitality Management Undergraduate Honors Theses

Abstract

Over 30% of adults in the US are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) 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 randomized, crossover design with a one-week washout period. Each test day EE, appetite, and cravings were assessed at 0, …

Programming Heart Disease: Does Poor Maternal Nutrition Alter Expression Of Cardiac Markers Of Proliferation, Hypertrophy, And Fibrosis In Offspring?, Cathy Chun

Honors Scholar Theses

Maternal malnutrition can affect fetal organogenesis, metabolic processes, and factors involved in developmental regulation. Of the many physiological effects poor maternal nutrition can induce in offspring, one of the most important organs affected is the heart. Cardiovascular disease has been associated with poor maternal diet. It also been suggested that hypertension can originate during impaired intrauterine growth and development. Hypertension can trigger hypertensive heart disease and is associated with numerous heart complications. We hypothesized that poor maternal nutrition would alter critical growth factors associated with normal heart development, specifically, insulin-like growth factor (IGF)-1, IGF-2, transforming growth factor (TGF)β, and connective …

How The U.S. Low-Fat Diet Recommendations Of 1977 Contributed To The Declining Health Of Americans, Julia Reedy

Honors Scholar Theses

In 1977, the first edition of The Dietary Goals for the United States (“The Recommendations”) was published in attempts to reduce incidence of diet-related diseases such as cardiovascular disease and diabetes. While numerous dietary adjustments were recommended in order to improve health, fat was identified as the most instrumental factor. However there exist many confounders of The Recommendations, including Medium Chain Triglycerides (MCT), fat from dairy products, eggs and the high-fat Mediterranean Diet. Nonetheless, the food industry made adjustments to acclimate to the anti-fat mentality The Recommendations initiated. Linoleic acid- (LA) rich soybean oil became heavily used, drastically altering the …

How Microbial Communities Differ In Ruminants On A Glycerin Vs Common Diet, Makala Muller, Nirosh D. Aluthge, Allison L. Knoell, Morgan Kaiser, Samodha C. Fernando

UCARE: Research Products

Can we reduce methane by using dietary interventions to reduce carbon footprint and increase feed efficiency? Ruminant livestock account for a significant amount of the anthropogenic methane produced in the U.S. All ruminant livestock produce 28% of the earth’s methane emissions. The methane within ruminants is produced by a microbial fermentation, especially by a group of bacteria known as the methanogens. However, the different species of methanogens and their pathways of methane production within ruminants are not fully understood. Cattle are considered one of the main producers of methane. They produce 20% of the U.S. methane emissions. Methane absorbs more …
