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

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 …

Akt-Mtorc1 Signaling Regulates Acly To Integrate Metabolic Input To Control Of Macrophage Activation, Anthony J. Covarrubias, Halil Ibrahim Aksoylar, Jiujiu Yu, Nathaniel W. Snyder, Andrew J. Worth, Shankar S. Iyer, Jiawei Wang, Issam Ben-Sahra, Vanessa Byles, Tiffany Polynne-Stapornkul, Erika C. Espinosa, Dudley Lamming, Brendan D. Manning, Yijing Zhang, Ian A. Blair, Tiffany Horng

Department of Nutrition and Health Sciences: Faculty Publications

Macrophage activation/polarization to distinct functional states is critically supported by metabolic shifts. How polarizing signals coordinate metabolic and functional reprogramming, and the potential implications for control of macrophage activation, remains poorly understood. Here we show that IL-4 signaling co-opts the Akt-mTORC1 pathway to regulate Acly, a key enzyme in Ac-CoA synthesis, leading to increased histone acetylation and M2 gene induction. Only a subset of M2 genes is controlled in this way, including those regulating cellular proliferation and chemokine production. Moreover, metabolic signals impinge on the Akt-mTORC1 axis for such control of M2 activation. We propose that Akt-mTORC1 signaling calibrates metabolic …

Effect Of Green Tea On Interaction Of Lipid Oxidation Products With Sarcoplasmic And Myofibrillar Protein Homogenates Extracted From Bovine Top Round Muscle, Nahathai Stapornkul, Tatiana Prytkova, Lilian Were

Food Science Faculty Articles and Research

The interaction between lipid oxidation products and bovine sarcoplasmic (SP) and myofibrillar protein (MP) homogenates in the presence of green tea was investigated. To monitor the effect of green tea on lipid oxidation, aldehydes were measured while effect on protein was monitored via changes in myoglobin, thiols, and tryptophan fluorescence over nine days of refrigerated storage. The presence of SP and MP decreased free aldehydes in the buffers. The SP bound more aldehydes than MP. The tea compounds exhibited more favorable binding energies than aldehydes near histidine 64 close to the heme moiety of myoglobin. Addition of tea lowered tryptophan …

A Moral Argument For Veganism, Dan Hooley, Nathan Nobis

Human Health Collection

In this essay, we argue for dietary veganism. Our case has two steps. First, we argue that, in most circumstances, it is morally wrong to raise animals to produce meat, dairy products, most eggs (a possible exception we discuss is eggs from pet chickens) and most other animal food products. Turning animals into food, and using them for their byproducts, causes serious harms to animals that are morally unjustified: that is, the reasons given to justify causing these kinds of harms – goods or alleged goods that result from animal farming and slaughter – are inadequate to justify the bad …

Food Insecurity And Housing Instability In Vulnerable Families, Christian King

Department of Nutrition and Health Sciences: Faculty Publications

Reducing the prevalence of household food insecurity has been a long-standing objective of the federal government. Previous research has found many negative consequences of food insecurity for families and households but has not examined its relationship with housing instability. Using longitudinal data from the Fragile Families and Child Wellbeing Study, difference-in-difference models show that food insecurity is associated with housing instability. The association remains statistically significant after accounting for potential selection and unobserved heterogeneity using propensity score matching and excluding households that experienced prior housing instability from the sample. Examining potential mediating factors, I find that material hardship explains about …

Nutrigenomic Functions Of Ppars In Obesogenic Environments, Soonkyu Chung, Young Jun Kim, Soo Jin Yang, Yunkyoung Lee, Myoungsook Lee

Department of Nutrition and Health Sciences: Faculty Publications

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that mediate the effects of several nutrients or drugs through transcriptional regulation of their target genes in obesogenic environments.This review consists of three parts. First, we summarize current knowledge regarding the role of PPARs in governing the development of white and brown/beige adipocytes from uncommitted progenitor cells. Next, we discuss the interactions of dietary bioactive molecules, such as fatty acids and phytochemicals, with PPARs for the modulation of PPAR-dependent transcriptional activities and metabolic consequences. Lastly, the effects of PPAR polymorphism on obesity and metabolic outcomes are discussed. In this review, we aim …

Glucagon Regulates Hepatic Lipid Metabolism Via Camp And Insig-2 Signaling: Implication For The Pathogenesis Of Hypertriglyceridemia And Hepatic Steatosis, Hai Wang, Miaoyun Zhao, Neetu Sud, Patricia Christian, Jing Shen, Yongyan Song, Anjeza Pashaj, Kezhong Zhang, Timothy P. Carr, Qiaozhu Su

Department of Nutrition and Health Sciences: Faculty Publications

Insulin induced gene-2 (Insig-2) is an ER-resident protein that inhibits the activation of sterol regulatory element-binding proteins (SREBPs). However, cellular factors that regulate Insig-2 expression have not yet been identified. Here we reported that cyclic AMP-responsive element-binding protein H (CREBH) positively regulates mRNA and protein expression of a liver specific isoform of Insig-2, Insig-2a, which in turn hinders SREBP-1c activation and inhibits hepatic de novo lipogenesis. CREBH binds to the evolutionally conserved CRE-BP binding elements located in the enhancer region of Insig-2a and upregulates its mRNA and protein expression. Metabolic hormone glucagon and nutritional fasting activated CREBH, which upregulated expression …

Regulation Of Obesity And Metabolic Complications By Gamma And Delta Tocotrienols, Lu Zhao, Xiefan Fang, Maurice R. Marshall, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

Tocotrienols (T3s) are a subclass of unsaturated vitamin E that have been extensively studied for their anti-proliferative, anti-oxidative and anti-inflammatory properties in numerous cancer studies. Recently, T3s have received increasing attention due to their previously unrecognized property to attenuate obesity and its associated metabolic complications. In this review, we comprehensively evaluated the recent published scientific literature about the influence of T3s on obesity, with a particular emphasis on the signaling pathways involved. T3s have been demonstrated in animal models or human subjects to reduce fat mass, body weight, plasma concentrations of free fatty acid, triglycerides and cholesterol, as well as …

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 …
