Local And State Governments Are Taking The Stage When It Is Fda's Curtain Call - Are Local And State Governments' Safety Warnings Preempted By Federal Law?, Melissa M. Card

Journal of Food Law & Policy

Eliminated from fad diets, sworn off by celebrities, and frantically reformulated out of processed foods, added sugars have been deemed the new nutritional scoundrel. Recent studies from the American Heart Association, the World Health Organization, and the American Cancer Association demonstrate that the consumption of added sugar leads to increased risks of obesity, diabetes, heart disease, and gout. While all foods containing added sugar are deemed unhealthy, Sugary-Sweetened Beverages ("SSBs") are said to be especially toxic by the American health community, by virtue of these beverages' being excessively high in added sugar content, low in satiety, and incomplete in compensation …

Will Consumers Be In The "Dark" About Labels On Genetically Engineered And Modified Foods?, Hilary Nat

Journal of Food Law & Policy

In the 1900s, the United States began to sell genetically engineered foods. One of the first genetically engineered foods sold in the United States and approved by the Food and Drug Administration (FDA) was the Flavr Savr tomato. The tomato's genetic structure was modified to prevent softening which allowed it to ripen after being picked. In the United States, statistics demonstrate that 92% of com, 94% of soybeans, and 94% of cotton sold is genetically engineered. In addition, it is estimated that 75% of the processed foods sold in supermarkets around the United States contain ingredients that are products of …

Energy Drink Regulations: Why The Time For More Fda Authority Is Not Ripe And How States Can Protect Children Without Unjustly Infringing On Adult Autonomy, Larry D. Treat

Journal of Food Law & Policy

In December of 2011, Anais Fournier ("Anais"), a fourteen-year-old from Maryland, was at the mall with her friends when she drank a twenty-four ounce Monster energy drink. Within twenty-four hours, Anais consumed a second twenty-four ounce energy drink. Together, the two Monster energy drinks Anais consumed contained around 480 milligrams ("mg") of caffeine. A few hours after the second drink, Anais went into cardiac arrest and later died from cardiac arrhythmia. An autopsy found that caffeine toxicity caused Anais's arrhythmia and impeded her heart's ability to pump blood. As it turns out, Anais suffered from a preexisting heart condition called …

Antimicrobial Inhibitory Activities Of Phenolic Extracts From Four Selected Soybean Hulls In Culture And Chicken Skin Model Systems, And Preliminary Ace-Inhibitory Activity, Rajaa Abdulkair Abutheraa

Graduate Theses and Dissertations

Soybean components provide health benefits to humans. Soybean hulls, a major by-product of the soybean processing industry consist of complex carbohydrates, proteins, lipids and polyphenols such as anthocyanidins, proanthocyanidins and isoflavones. The polyphenolic compounds in the hulls give them various colors such as black, brown, green, yellow or even a mottled appearance. Studies have reported different soybean varieties with varying total phenolic compounds in their seed hulls, which have antioxidant property. Phenolic extracts can be used as substitutes for synthetic antimicrobials and preservatives to assist in preventing the growth of pathogens such as Salmonella Typhimurium, E coli 0157:H7, and Campylobacter …

Quantitative Trait Loci (Qtl) For Salt Tolerance In Soybean And Physiological Response To Salt Stress During Early Growth Stage, Cindy Massiel Lopez Ramirez

Graduate Theses and Dissertations

Soybean is a major cash crop used as a source of high–quality protein and oil. Salt stress is one of the main abiotic stresses causing significant yield losses in soybean, which is considered a moderately salt–sensitive crop. Breeding selection is a promising strategy to improve salt tolerance as soybean germplasm display wide variation in response to salinity stress. However, the physiological and genetic mechanisms for salt tolerance are not quite clear. The discovery of novel QTL/genes associated with salt tolerance facilitates the development of tolerant cultivars through marker-assisted selection (MAS). The objectives of this study were: 1) identify/confirm QTL associated …

The Role Of Organic Matter In The Fate And Transport Of Antibiotic Resistance, Metals, And Nutrients In The Karst Of Northwest Arkansas, Victor Lee Roland Ii

Graduate Theses and Dissertations

Organic matter (OM) in the environment acts as a nutrient, but may also act as a transport vector for harmful chemical compounds and bacteria. Acetate is a labile form of OM produced during fermentation in anaerobic lagoons used to store animal fecal-waste from concentrated animal feeding operations (CAFOs). Dry and liquid fertilizers from CAFOs pose a threat to groundwater by introducing excessive amounts of nutrients (e.g. OM, nitrate and ammonia), metals, and antibiotic compounds. In the epikarst of Northern Arkansas in the Buffalo River watershed additional input of labile dissolved organic carbon (DOC) from liquid CAFO waste-fertilizers was hypothesized to …

Agro-Climatic Change, Crop Production And Mitigation Strategies-Case Studies In Arkansas, Usa And Kenya, John Westley Magugu

Listeria Monocytogenes Strain Variation: Starvation, Metabolism, And Macrophage Survival, Nathan A. Jarvis

Graduate Theses and Dissertations

Listeria spp. are often isolated from raw and processed food products. Listeria monocytogenes is responsible for death rates of 10 to 30% in immune compromised people; it can also infect a vast range of animals. There are numerous reports of poultry harboring or becoming infected with L. monocytogenes. First, this research assessed the ability of L. monocytogenes to replicate within chicken macrophages. Using the gentamicin-killing assay, a cell culture of chicken macrophage-like cells (HD11) were infected with two strains of L. monocytogenes individually (EGD-e and Scott A). Results show that unlike data on mouse macrophages, intracellular L. monocytogenes do not …

It's Not The Load That Breaks You Down, It's The Way You Carry It: An Examination Of The Relationship Between Negative Identity And Consumer Behavior, Cassandra Denise Davis

Graduate Theses and Dissertations

Research examining Social identity and consumer behavior often centers on groups with positive Social identities, exploring the influence of similar identities (i.e., shared values, shared gender, shared political affiliations, shared ethnicity…etc.) or desired identities (e.g., sports celebrities, actors, and actresses). For example, research has shown that people display an increased attention to identity-based stimuli following the activation of a Socially distinct identity (Forehand, Deshpandé, and Reed 2002) and that heightening the self‐importance of a consumer Social identity leads to a preference for identity-related brands (Reed 2004). An important but often overlooked aspect of the influence of Social identity on consumption, …

Graduate Theses and Dissertations

The prevalence of colorectal cancer (CRC) has been increasing in recent years worldwide. In the United States, it is ranked the second leading cause of cancer death. Risks of CRC increase with age and are associated with several lifestyle factors such as diet, drinking and smoking habits, and levels of physical activity. There is an abundance of scientific literature demonstrating the protective roles of several dietary components including fibers and polyphenolic compounds. These compounds have been shown to be able to positively modulate gastrointestinal ecology by increasing the production of short-chain fatty acids (SCFA) and promoting the population of beneficial …

Test Of An Adolescent Anxiety Sensitivity Amelioration Program (Aasap) For At-Risk Youth, Ashley Arehart Knapp

Graduate Theses and Dissertations

Adult research supports the effectiveness of targeting the malleable vulnerability factor of anxiety sensitivity (AS) in terms of preventing panic specifically and anxiety psychopathology generally. Risk factor research suggests AS modification among youth has implications for panic as well as generalized anxiety disorder (GAD). However, very little work has evaluated the impact of AS reduction among youth, which is unfortunate given adolescence is a period of “core risk” in terms of anxiety disorder onset. Further, no work has considered the effect of such a program on GAD-relevant outcomes, nor has any work included family-level intervention factors, despite evidence suggesting parents …
