Food Webs And Food Sovereignty: Research Agenda For Sustainability, Charles A. Francis, Michelle Miller, Molly Anderson, Nancy Creamer, Michelle Wander, Jacob Park, Thomas Green, Brent Mccown

Department of Agronomy and Horticulture: Faculty Publications

Future food production will be constrained by the scarcity of fossil fuel and fresh water as well as increasing intensity and unpredictability of weather events and climate changes. The assurance of food security and equity for many consumers is complicated by concentration of ownership of land and other production resources, as well as a global corporate food systems model that is driven by profit at the expense of people and the environment. To assess potential alternatives to the contemporary global food chain, well focused research is needed on local food production and food webs where small- and midscale family farms …

The purpose of this study is to examine the body mass index (BMI) trends of college students at the University of Nebraska-Lincoln, between the years 2007-2011 and to determine the nutrition-related goals of these students. Data was previously collected from NUTR …

School Food Environment The Frontline For Childhood Obesity Prevention: A Mixed-Method Study Of Nutritional Competencies And Skills Of School Nutrition Professionals In Nebraska, Zainab Rida

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

The purpose of this statewide study was to address the nutrition knowledge, attitudes, and perceptions of school foodservice personnel in Nebraska regarding offering/serving healthy school meals. Moreover, this study identified some potential barriers and avenues of action for offering/serving healthy school meals. Data obtained from this study indicates that there is a strong correlation (r= .103, p r .237, p< .01) between the foodservice staff’s self-efficacy and their practices of offering/serving healthy school meals. Fortunately, the relationship between foodservice staff practices of offering/serving healthy school meals and their self-efficacy was positive and significantly predicted practices scores, β =.237, P< 0.01. The finding of the present study also identifies many barriers including lack of time and support that face the foodservice personnel in offering/serving healthy school meals. The findings suggested that there is an urgent need of a full school approach to promote and encourage healthy eating habits among students. Future research is needed to evaluate school wellness policies regarding healthy eating practices in schools. Moreover, establish partnerships with communities and universities for intervention that target students and their parents.

A total of 60 RDs (57% response rate) responded to an electronic questionnaire. Descriptive statistics and χ² analyses (SPSS, version 18) were used. Results revealed the primary form of diet was oral, and for patients on nutrition support, parenteral nutrition (PN) was used more frequently (16%–31%) than enteral nutrition (EN) (5%–9%; P ≤ .05). Nutrition support decisions were based on patients’ individualized needs rather than established …

A Pilot Study: The Use Of A Survey To Assess The Food Knowledge Of Nutrition Students At Various Levels Of Nutrition Education, Chante Chambers

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

A working definition of a concept known as ‘food literacy’ encompasses using basic food preparation knowledge that has been learned, understood, and practiced to make better food decisions. To advance these skills for client service, a post-secondary nutrition program would need to include objectives that allow application of knowledge. For this reason, the purpose of this study was to determine the difference in knowledge and application among students in 100, 200 and 400 level college nutrition course(s). A survey was developed to measure the food knowledge of these college students as they prepare for careers as health care professionals. The …

Impact Of The Home Food Environment On Dietary Intake, Obesity And Cardiovascular Health Of U.S. Children And Adolescents, Aged 6–19, Melissa A. Masters

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

Youth obesity is an ongoing problem in the United States. Obese children and adolescents are likely to be obese as adults and have an increased risk of developing chronic diseases, including coronary heart disease, earlier in life. The multifactorial nature of obesity continues to challenge researchers and health professionals to determine methods for preventing and reducing childhood obesity. Research has suggested that obesity is a normal response to an “obesigenic” environment. Emerging as one of the most influential environments in obesity and behavior development is the home food environment. However, little is understood about the role of the home food …

Dietitian’S Problem Solving Knowledge To Promote And Support Breastfeeding, Cassandra L. Dytrych

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

As a result of ongoing efforts in the U.S. to promote breastfeeding as the normal way to nourish an infant, breastfeeding initiation rates are higher than they have been in decades. As the experts on food and nutrition through the lifecycle, registered dietitians (RDs) should be knowledgeable to promote and support breastfeeding. It is not well known if RDs have this knowledge. The purpose of this study was to determine the current knowledge of RDs about breastfeeding, the types of professional opportunities RDs have to promote and support breastfeeding, and the level of education RDs have to deal with breastfeeding …

Microbial Co-Occurrence Relationships In The Human Microbiome, Karoline Faust, J. Fah Sathirapongsasuti, Jacques Izard, Dirk Gevers, Jeroen Raes, Curtis Huttenhower

Department of Food Science and Technology: Faculty Publications

The healthy microbiota show remarkable variability within and among individuals. In addition to external exposures, ecological relationships (both oppositional and symbiotic) between microbial inhabitants are important contributors to this variation. It is thus of interest to assess what relationships might exist among microbes and determine their underlying reasons. The initial Human Microbiome Project (HMP) cohort, comprising 239 individuals and 18 different microbial habitats, provides an unprecedented resource to detect, catalog, and analyze such relationships. Here, we applied an ensemble method based on multiple similarity measures in combination with generalized boosted linear models (GBLMs) to taxonomic marker (16S rRNA gene) profiles …

Structure, Function And Diversity Of The Healthy Human Microbiome, Curtis Huttenhower, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Studies of the human microbiome have revealed that even healthy individuals differ remarkably in the microbes that occupy habitats such as the gut, skin and vagina. Much of this diversity remains unexplained, although diet, environment, host genetics and early microbial exposure have all been implicated. Accordingly, to characterize the ecology of human-associated microbial communities, the Human Microbiome Project has analysed the largest cohort and set of distinct, clinically relevant body habitats so far. We found the diversity and abundance of each habitat’s signature microbes to vary widely even among healthy subjects, with strong niche specialization both within and among individuals. …

Mixed Methods Analysis Of School Wellness Programs In Nebraska And Indiana: A Descriptive Study, Jessica A. Robinson

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

Schools have become one of the major fronts that the battle against childhood obesity is being fought. In 2004 the Child Nutrition Act passed by Congress required all school districts receiving funds for the National School Lunch Program to create a wellness policy. Since then there have been many research projects conducted to learn more about these policies, and their implementation as programs in the schools. Thus far, no such research has been done in Nebraska or Indiana. The purpose of this descriptive study is to describe how schools in Nebraska and Indiana are implementing wellness programs in their schools. …

Evolution Of Starvation Resistance In Drosophila Melanogaster: Measurement Of Direct And Correlated Responses To Artificial Selection, Tiffany E. Schwasinger-Schmidt, Stephen D. Kachman, Lawrence G. Harshman

Lawrence G. Harshman Publications

Laboratory selection for resistance to starvation has been conducted under relatively controlled conditions to investigate direct and correlated responses to artificial selection. With regard to starvation resistance, there are three physiological routes by which the trait can evolve: resource accumulation, energy conservation and starvation tolerance. A majority of energetic compounds and macromolecules including triglycerides, trehalose and other sugars, and soluble protein increased in abundance as a result of selection. Movement was additionally investigated with selected males moving less than control males and selected females exhibiting a similar response to selection. Results obtained from this study supported two of the possible …

Department of Nutrition and Health Sciences: Faculty Publications

Glycerol is prohibited as an ergogenic aid by the World Anti-Doping Agency (WADA) due to the potential for its plasma expansion properties to have masking effects. However, the scientific basis of the inclusion of Gly as a “masking agent” remains inconclusive. The purpose of this study was to determine the effects of a hyperhydrating supplement containing Gly on doping-relevant blood parameters. Nine trained males ingested a hyperhydrating mixture twice per day for 7 days containing 1.0 g·kg⁻¹ body mass (BM) of Gly, 10.0 g of creatine and 75.0 g of glucose. Blood samples were collected and total hemoglobin (Hb) …

Regulation Of Expression Of Citrate Synthase By The Retinoic Acid Receptor-Related Orphan Receptor A (Rorα), Christine Crumbley, Yongjun Wang, Subhashis Banerjee, Thomas P. Burris

Department of Nutrition and Health Sciences: Faculty Publications

The retinoic acid receptor-related orphan receptor α (RORα) is a member of the nuclear receptor superfamily of transcription factors that plays an important role in regulation of the circadian rhythm and metabolism. Mice lacking a functional RORα display a range of metabolic abnormalities including decreased serum cholesterol and plasma triglycerides. Citrate synthase (CS) is a key enzyme of the citric acid cycle that provides energy for cellular function. Additionally, CS plays a critical role in providing citrate derived acetyl-CoA for lipogenesis and cholesterologenesis. Here, we identified a functional RORα response element (RORE) in the promoter of the CS gene. ChIP …

Regulation Of P53 Stability And Apoptosis By A Ror Agonist, Yongjun Wang, Laura A. Solt, Douglas J. Kojetin, Thomas P. Burris

Department of Nutrition and Health Sciences: Faculty Publications

Activation of p53 function leading to cell-cycle arrest and/or apoptosis is a promising strategy for development of anticancer therapeutic agents. Here, we describe a novel mechanism for stabilization of p53 protein expression via activation of the orphan nuclear receptor, RORa. We demonstrate that treatment of cancer cells with a newly described synthetic ROR agonist, SR1078, leads to p53 stabilization and induction of apoptosis. These data suggest that synthetic ROR agonists may hold utility in the treatment of cancer.

Cgi-58/Abhd5-Derived Signaling Lipids Regulate Systemic Inflammation And Insulin Action, Caleb C. Lord, Jenna L. Betters, Pavlina T. Ivanova, Stephen B. Milne, David S. Myers, Jennifer Madenspacher, Gwynneth Thomas, Soonkyu Chung, Mingxia Liu, Matthew A. Davis, Richard G. Lee, Rosanne M. Crooke, Mark J. Graham, John S. Parks, Dawn L. Brasaemle, Michael B. Fessler, H. Alex Brown, J. Mark Brown

Department of Nutrition and Health Sciences: Faculty Publications

Mutations of comparative gene identification 58 (CGI-58) in humans cause Chanarin-Dorfman syndrome, a rare autosomal recessive disease in which excess triacylglycerol (TAG) accumulates in multiple tissues. CGI-58 recently has been ascribed two distinct biochemical activities, including coactivation of adipose triglyceride lipase and acylation of lysophosphatidic acid (LPA). It is noteworthy that both the substrate (LPA) and the product (phosphatidic acid) of the LPA acyltransferase reaction are wellknown signaling lipids. Therefore, we hypothesized that CGI-58 is involved in generating lipid mediators that regulate TAG metabolism and insulin sensitivity. Here, we show that CGI-58 is required for the generation of signaling lipids …

Effect Of Diet Quantity And Quality On Female Sampling Behavior And Mating Preferences In A Field Cricket, Heidi L. Bulfer

School of Biological Sciences: Dissertations, Theses, and Student Research

Understanding the adaptive significance of variation in female mating behaviour is important because variation may often be favored by selection instead of a change in mean mating behaviour, particularly in variable environments. Females are known to adjust their mating behaviour to a variety of intrinsic and extrinsic factors including nutrition. There are multiple reasons why female behaviours might vary with nutrition; we tested two of these hypotheses: the search cost hypothesis and the direct benefits hypothesis. These hypotheses are not mutually exclusive, but they make contrasting predictions under some conditions. Low nutrition females may have less available energy to support …

Perceived Importance And Actual Intake Of Calcium And Vitamin D In Young Female Athletes, Miriam E. Zambrano

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

Calcium needs increase as a child grows. Actual intake often decreases as a child gets older, leaving his/her developing bones at risk for injury during childhood and increasing the risk of developing osteoporosis later in life. The purpose of this study was to investigate relationships between psychosocial factors influencing consumption of calcium and vitamin D-rich foods and actual intakes of these nutrients. We examined the dietary calcium and vitamin D intakes, determined serum vitamin D levels, and assessed nutrition knowledge and perception of a sample of 20 young girls participating in competitive cheerleading in Omaha, Nebraska. From this information we …

Effects Of Single Nucleotide Polymorphisms In The Human Holocarboxylase Synthetase Gene On Catalytic Activity, Shingo Esaki

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

Holocarboxylase synthetase (HCS) catalyzes the covalent binding of biotin to carboxylases and histones in eukaryotic cells. Biotinylated carboxylases play essential roles in the metabolism of fatty acids, amino acids, and glucose; biotinylated histones play essential roles in gene regulation and genome stability. HCS null individuals are not viable whereas HCS deficiency is linked to developmental delays and phenotypes such as short life span and low stress resistance. Greater than 2,500 single nucleotide polymorphisms (SNPs) have been reported for HCS, but the biological importance of these polymorphisms is unknown. We hypothesized that some of these SNPs impair catalytic activity and that …

Intervention To Increase Knowledge And Consumption Of Folate-Rich Foods Based On The Health Belief Model, Lindsay M. Labrosse

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

Folate is important in the prevention of birth defects and in the maintenance of general health. Even after mandatory fortification, many people are still not consuming the RDA of 400 mcg/day. Consuming a diet rich in naturally high-folate foods, as opposed to supplementation, may offer additional health benefits and promote an overall healthy diet.

The purpose of this pilot study was to test the hypothesis that a learner-centered educational intervention based on the Health Belief Model (HBM) will successfully increase knowledge and consumption of folate-rich foods, while increasing positive beliefs about folate and health. A two group parallel control trial …

High-Density Lipoprotein Metabolism In Human Apolipoprotein B100 Transgenic/Brown Adipose Tissue Deficient Mice: A Model Of Obesity-Induced Hyperinsulinemia, Sarah J. Ehlers, Stephanie M. Larson, Heather E. Rasmussen, Young-Ki Park, Ji-Young Lee

Department of Nutrition and Health Sciences: Faculty Publications

Obese and diabetic humans display decreased plasma high-density lipoprotein cholesterol (HDL-C) concentrations and an increased risk for coronary heart disease. However, investigation on HDL metabolism in obesity with a particular emphasis on hepatic ATP-binding cassette transporter A1 (ABCA1), the primary factor for HDL formation, has not been well studied. Human apolipoprotein B₁₀₀ transgenic (hApoB^tg) and brown adipose tissue deficient (BATless) mice were crossed to generate hApoB^tg/BATless mice. Male and female hApoB^tg and hApoB^tg/BATless mice were maintained on either a regular rodent chow diet or a diet high …

Regulation Of Sterol Transport By Dietary Phytosterol Esters, Trevor J. Carden

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

LDL cholesterol is associated with the development of atherosclerosis and is therefore considered an important target for intervention to prevent cardiovascular diseases. The inhibition of cholesterol absorption in the small intestine is an attractive approach to lowering plasma cholesterol, one that is exploited by drug therapy as well as dietary supplementation with plant sterols. The mechanism of action of plant sterol esters (PSE) is still incompletely understood, therefore this study was conducted to test the hypothesis that hydrolysis of plant sterol esters is necessary for their cholesterol-lowering effects to be realized.

Male Syrian hamsters were fed diets containing no PSE, …

Unsaturated Fatty Acids Repress The Expression Of Atp-Binding Cassette Transporter A1 In Hepg2 And Fhs 74 Int Cells, Chai Siah Ku, Heather E. Rasmussen, Young-Ki Park, Elliot D. Jesch, Ji-Young Lee

Department of Nutrition and Health Sciences: Faculty Publications

Adenosine triphosphate–binding cassette transporter A1 (ABCA1) plays a critical role in the formation and metabolism of high-density lipoproteins (HDLs). Adenosine triphosphate–binding cassette transporter A1 in the liver and small intestine, in particular, accounts for approximately 90% of plasma HDL cholesterol. Therefore, any alterations in the hepatic and intestinal expression of ABCA1 could have a large impact on HDL biogenesis. We tested the hypothesis that ABCA1 expression is regulated differentially by different types of fatty acids in the liver and small intestine. Human hepatoma HepG2 and human small intestine epithelial FHs 74 Int cells were used as an in vitro model. …

Preschool Children’S Willingness To Try And Preference For Docosahexaenoic Acid Omega-3 Foods, Bethany Joann Bettenhausen

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

During the preschool years, obesigenic eating habits are formed which are strongly associated with risk of developing chronic diseases later in life particularly cardiovascular disease. Docosahexaenoic acid (DHA) omega-3 fatty acid is a polyunsaturated fat with known benefits for heart health, brain cell structure, and retinal development. Current intakes of DHA are below recommended levels. United States (US) Midwestern children may be particularly at risk for suboptimal intakes of DHA. However, foods fortified with life’sDHA^TM, a product of Martek Biosciences and omega-3 eggs may provide culturally acceptable sources of DHA to Midwestern children.

Very little is known about …

Effect Of Brown Midrib Corn Silage And Dried Distillers Grains Plus Solubles On Lactational Performance And Nitrogen Utilization By Dairy Cows, Hugo A. Ramirez

Department of Animal Science: Dissertations, Theses, and Student Research

Thirty six Holstein cows, four ruminally cannulated, (mean ± SD, 111 ± 35 DIM; 664 ± 76.5 kg BW) were used in replicated 4×4 Latin squares to investigate the effects of brown midrib (bm3) and conventional (DP) corn silages, and the inclusion of dried distillers grains plus solubles (DDGS) on milk production and N utilization. In each 28 d period cows were assigned to one of four treatments: DP plus 0% DDGS (CON); bm3 plus 0% DDGS (BMR); DP corn silage plus 30% DDGS (DP+DG); and bm3 plus 30% DDGS (BMR+DG). Dry matter intake was greater (P < 0.01) for cows consuming bm3 (25.8 VS 24.4 ± 0.47 kg), likewise for DDGS (24.3 and 25.9 ± 0.47 kg/d for 0 and 30%). Compared to DP hybrid, NDFD was higher (P < 0.01) for bm3 (32.5 VS 38.1 ± 1.79%). There was a hybrid × DDGS interaction (P < 0.01) for total concentration of volatile fatty acids (VFA) and rumen pH as the highly digestible treatment BMR+DG resulted in the highest VFA and the lowest pH. Milk yield was not affected by treatment and averaged 30.6 ± 1.09 kg/d. Milk protein yield (MPY) was greater (P < 0.01) for bm3 and DDGS treatments. There was a hybrid by DDGS interaction (P = 0.02) for milk fat yield (MFY) resulting in 1.03, 1.08, 0.84 and 0.78 ± 0.045 kg/d for DP, BMR, DP+DG and BMR+DG. Fat corrected milk (FCM) was affected by DDGS (P < 0.01) and averaged 30.0 and 26.4 ± 1.0kg/d (0% and 30% inclusions). Urinary N excretion was similar among treatments; however fecal N was lower (P = 0.03) for diets containing bm3 corn silage which caused lower (P = 0.02) manure N. These results indicate that bm3 corn silage and DDGS increase DMI, NDFD and MPY; however high inclusion of corn silage with 30% DDGS reduces FCM. Nitrogen excretion was reduced when cows consumed bm3.
