The global population, including the United States, is experiencing a demographic shift with the proportion of older adults (aged ≥ 65 years) growing faster than any other age group. This demographic group is at higher risk for developing nutrition-related chronic conditions such as heart disease and diabetes as well as infections such as influenza and pneumonia. As a result, an emphasis on nutrition is instrumental for disease risk reduction. Unfortunately, inadequate nutrient status or deficiency, often termed hidden hunger, disproportionately affects older adults because of systematic healthcare, environmental, and biological challenges. This report summarizes the unique nutrition challenges facing the …

Research Note Prediction Model For Manure Zinc Excretion In Laying Hens, Kelli M. Martin, N. Vargas-Jurado, S. E. Purdum

Department of Animal Science: Faculty Publications

The objective of this research trial was to compare 2 sources of zinc and different levels of supplementation on manure zinc excretion in laying hens. Bovan White Leghorn hens were used in this study and fed one of 6 dietary treatments. Treatments were in a 2 × 3 factorial arrangement with 2 sources of zinc (zinc sulfate or Availa R < Zn) and 3 levels (40, 80, or 120 ppm) and were randomly assigned to 48 cages with 5 hens/cage and 8 replicates/treatment. Hens were housed in a tiered manure-belt housing system providing 627.1 cm2/hen and were given access to 110 g/hen/d of feed. Manure samples were collected, and manure zinc content was calculated at 10- week intervals. Data were analyzed using the Glimmix procedure in SAS. There was a significant overall effect of source (P < 0.0001) for zinc content, such that hens fed zinc sulfate had lower amounts of zinc excretion. There was also a significant level effect (P < 0.0001) in which hens fed 120 ppm zinc excreted the greatest amount of zinc. A significant source by level interaction was observed (P < 0.0001) for both the overall and individual analyses, such that 120 ppm Availa R < Zn showed the highest zinc excretion, and both 40 ppm zinc sulfate and Availa R < Zn showed the lowest zinc excretion. Based on these results, a prediction equation was written for an estimated amount of zinc excretion based on the amount of zinc provided in the diet.

Essential Components Of Participation For An Exercise Program For Underserved, Older, African-American Females, Marina Meinert

Honors Undergraduate Theses

Physical activity (PA) is beneficial to people of all ages and ethnicities. Regular physical activity can reduce the risk of multiple chronic diseases, improve mood and sleep and allows your body to function better overall (CDC, 2018). However, populations that are more vulnerable to adverse health risks may benefit more than others from regular physical activity. This study was designed to identify the motivating factors for physical activity in a sample of older, African-American women of lower socioeconomic status (SES). This particular subgroup was chosen because of their increased risk of obesity and cardiovascular disease due to unhealthy lifestyle factors, …

The Politics Of U.S. Food Policy, Evan Murphy

CMC Senior Theses

Throughout the 20th century, American farmlands, agricultural policy, and diets have seen dramatic transformations. The number of farms in America has decreased, but the average size of farms has increased. These larger farms are increasingly more industrialized and produce a short list of profitable, subsidized commodity crops. Similarly, changes in the American diet throughout the 20th and 21st centuries have reflected these shifts in the landscape of American farmland. Simultaneous to the evolution of American farms was an increase in federal involvement in American agriculture through policy that seems to encourage these trends. Although separating out the causes from the …

Home Is Where The Food Is: Causes And Consequences Of Partial Migration In Elk, Kristin Jennifer Barker

Graduate Student Theses, Dissertations, & Professional Papers

Migratory and non-migratory ungulates often coexist in partially migratory populations, but the mechanisms that drive and maintain different migratory behaviors within the same herd are poorly understood. In western North America, increasing numbers of elk (Cervus canadensis) reside on low-elevation winter range year-round. These residents can cause issues associated with crop damage, potential for disease transmission to livestock, and reduced effectiveness of harvest management strategies. Because migrants transfer nutrients, alter carnivore distributions, and structure vegetative communities across seasonal ranges, reductions in migratory behavior raise ecological as well as management-related concerns. This work investigated the factors affecting migratory behavior …

Examining The Credentials Of Food Bloggers And The Online Environment Of Food Blogs, Jessica Coburn

Master's Theses and Doctoral Dissertations

This study evaluated characteristics of food blogs and food bloggers that potentially affect food choices. It was hypothesized that most food bloggers would not have a nutrition-related degree and food blog environments wouldn’t be supportive of health-conscious food choices. A cross-sectional study was conducted using a novel evaluation tool on 187 blogs, out of which 100 blogs met inclusion criteria. Because some blogs had multiple bloggers, two samples were investigated: 111 bloggers (n1 = 111) and 100 food blogs (n2 = 100). Data were gathered from a randomized list of blogs taken from americanfoodbloggers.com. Results showed that 6% of bloggers …

Pcb Disruption Of Gut And Host Health: Implications Of Prebiotic Nutritional Intervention, Jessie Baldwin Hoffman

Theses and Dissertations--Pharmacology and Nutritional Sciences

Exposure to environmental pollutants poses numerous risk factors for human health, including increasing incidence of cardiovascular disease and diabetes. Persistent organic pollutants, such as polychlorinated biphenyls (PCBs) have been strongly linked to the development of these chronic inflammatory diseases and the primary route of exposure is through consumption of contaminated food products. Thus, the gastrointestinal tract is susceptible to the greatest levels of these pollutants and is an important facet to study.

The first two hypotheses of this dissertation tested that exposure to PCBs disrupts gut microbiota directly (in vitro) and within a whole body system. PCB exposure …

Utilization Of Web‐Based App To Target Obesogenic Factors In Rural Kentucky Counties With High Rates Of Obesity, Erin M. Casey

Theses and Dissertations--Nutrition and Food Systems

Due to socioeconomic disparities and geographic isolation, rural Kentucky residents bear a greater burden of poor health compared to national averages. Specifically, rural Kentucky residents are at greater risk of becoming obese and suffering from comorbidities of obesity such as type 2 diabetes, hypertension and cardiovascular disease. The purpose of the present study was two-fold. First, we the barriers to nutrition and physical activity unique to rural Kentucky counties which high proportions of obese adults (< 40%) were examined and extrapolated. Second, this information was used to develop a health and wellness app tailored to rural Kentucky counties. The objective was met via a formative assessment regarding causes for obesity in three rural Kentucky counties using focus groups. From these discussions, two major themes arose: barriers to good nutrition and physical activity, and desired web‐app features. From this assessment, FitFaceoff was developed and released into the same counties. Usage and user interaction were assessed using GoogleAnalytics™ software. Analysis revealed poor user liking and unsuccessful implementation of FitFaceoff, however further qualitative research is needed to evaluate poor user reception of FitFaceoff and possible future directions.

Exploring Lactate’S Role In Appetite Regulation Following High-Intensity Exercise, Luke W. Vanderheyden

Theses and Dissertations (Comprehensive)

Background: Intense-exercise has demonstrated an appetite suppressing effect post-exercise, however the involved mechanisms are not well understood. Lactate appears to be one viable mechanism as it has been found to bind to receptors on acylated ghrelin to inhibit release in cell culture. As sodium bicarbonate (NaHCO₃) can alter lactate accumulation post-exercise without manipulating exercise-intensity, it presents an intriguing means to investigate lactate’s potential role. Purpose: To examine the role of lactate on appetite using NaHCO₃ to alter blood lactate concentrations during high-intensity exercise. Methods: Eight recreationally active males completed two identical exercise sessions of low-volume high-intensity interval …

Nutritional Depletion Of Total Mixed Rations By European Starlings: Projected Effects On Dairy Cow Performance And Potential Intervention Strategies To Mitigate Damage, James C. Carlson, R. S. Stahl, S. T. Deliberto, J. J. Wagner, T. E. Engle, R. M. Engeman, C. S. Olson, J. W. Ellis, S. J. Werner

United States Department of Agriculture Wildlife Services: Staff Publications

European starlings are an invasive bird species in North America that are known to cause damage to commercial dairies through the consumption of total mixed rations (TMR) destined for dairy cows. We hypothesized that large foraging flocks of starlings alter the physical composition of TMR, and that this change may be significant enough to affect milk production. To better determine if production losses could potentially occur in commercial dairies as a consequence of feed consumption by foraging flocks of starlings, we conducted controlled feeding experiments using a TMR sourced from a commercial dairy that is chronically plagued with seasonal starling …

Context-Dependent Interactive Effects Of Non-Lethal Predation On Larvae Impact Adult Longevity And Body Composition, Karthikeyan Chandrasegaran, Samyuktha Rao Kandregula, Suhel Quader, Steven A. Juliano

Faculty Publications – Biological Sciences

Predation impacts development, behavior and morphology of prey species thereby shaping their abundances, distribution and community structure. Non-lethal threat of predation, specifically, can have a strong influence on prey lifehistory characteristics. While investigations often focus on the impact of predation threat on prey in isolation, tests of its interactive effects with food availability and resource competition on prey survival and fitness can improve understanding of costs, benefits and trade-offs of anti-predator strategies. This study, involving Aedes aegypti mosquitoes as a model organism, investigates both simple and interactive effects of predation threat during the larval stage on survival, size at and …

Evaluation Of The Factors Influencing Feed Intake And Satiety Of The Variegated Sea Urchin, Lytechinus Variegatus, Marlee Hayes

All ETDs from UAB

Feed intake is the primary determinant of nutrient and energy acquisition for most metazoans. Satiety regulates feed intake and may have cascading effects on nutrient acquisition and health. Satiety of many higher organisms involves complex processes and a variety of signaling molecules that are responsive to many factors associated with nutrient intake. However, the ability to sate is observed in many simpler animals with less complex physiological processes. Sea urchins, with relatively simple digestive and nervous systems, provide an ideal model for the study of fundamental drivers of feed intake. Understanding the process of satiety in this primitive deuterostome can …

Protein And Lipid Characterization Of Acheta Domesticus, Bombyx Mori, And Locusta Migratoria Dry Flours, Emily N. Brogan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cricket (Acheta domesticus), silkworm pupae (Bombyx mori), and locust (Locusta migratoria) dry flours were obtained to examine the biochemical properties and composition of the flours. This study aimed to characterize the protein and lipid components of three insect species utilizing proximate composition analyses, amino acid composition analysis, protein solubility, SDS-PAGE, fatty acid composition analysis, and thin layer chromatography to determine lipid classes, and lipid extraction efficiency. Kjeldahl determined the cricket, locust, and silkworm flours contained 72.0%, 53.1%, and 71.2% protein, respectively. All proximate composition analyses were significantly (p< 0.05) different between species. Amino acid composition analysis revealed that the flours contained 3.6-3.9% and 0.90-1.5% of lysine and methionine, respectively. Many countries have cereal grains and legumes as a staple in their diet that contain these limiting amino acids. Essential amino acids were 22% of total amino acids. Protein solubility revealed that the three species studied were most soluble in alkaline environments with highest protein solubility occurring at pH 13 at 66% solubility in silkworm. Lowest solubility occurred in more acidic conditions between pH 4-5. SDS-PAGE revealed five major protein fractions with estimated molecular weights of 27 (cuticle proteins), 41 (arginine kinase), which has been identified as an allergen in shrimp, 42 (actin), 71 (hemocyanin), and 220 myosin) kDa. Soxhlet extraction determined cricket, silkworm, and locust flours contained 15.4%, 33.3%, and 11.4% lipid, respectively. The only omega-3 fatty acid found in the flours was α-linolenic acid. Silkworm flour contained the most α-linolenic acid at 33.3% of total fatty acids, followed by locust (13.7%), and cricket (0.6%). TLC resolved lipids for typical lipid classes. The four major lipid classes noted were triacylglycerol, free fatty acid, cholesterol, and phospholipid. Lipid extraction efficiency found that the organic solvents chloroform and methanol had the highest lipid extraction yield in both cricket (69.3%) and locust (93.0%). Methyl-tertiary-butyl ether (MTBE) extracted lipids most efficiently in the silkworm. Proteins and lipids found in insects need to be isolated to further or commercial use.
