A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal

Journal of Human Performance in Extreme Environments

In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …

Antioxidant Properties And Anti-Cancer Effects Of Polyphenols In Sweetpotato Leaves, Josue Bolanos

Graduate Theses and Dissertations

Although the root is widely consumed, sweetpotato leaves (SPL) are often discarded and are only consumed in a few countries. In the United States, SPL consumption is limited to private gardens, particularly in the Southeastern United States. Not only are SPL a good source of nutrients such as vitamins and minerals, but they also contain polyphenol compounds including the caffeoylquinic acid derivatives and carotenoids such as lutein. Several studies have shown the polyphenol contents and antioxidant capacities of SPL, which vary based on year and variety, while few studies have shown anti-colon cancer effects of SPL. Therefore, this study investigated …

The Impact Of Dietary Egg Intake On Metabolic Health In Food Insecure Households, Sam Walker

Graduate Theses and Dissertations

Food Insecurity (FI) is defined as a condition in which individuals lack access to adequate food due to limited financial resources. FI is estimated to impact 12% of households in United States. Adults and children who experience FI are an increased risk for developing metabolic disease such as type 2 diabetes, obesity, hypertension, and cardiovascular disease. The negative health outcomes associated with FI are multi-factorial, however, many of them may be caused by limited nutritional intake and poor diet quality. Efforts to better understand the obstacles food insecure populations face is critical in order to improve nutrient intake and minimize …

Effects Of Lasalocid And Energy Supplementation On Forage Intake, Energy Metabolism, And Performance Of Cattle Grazing Wheat Pasture, Autumn Tayler Pickett

Graduate Theses and Dissertations

Cattle grazing wheat pasture have the potential to gain BW exceptionally well, but excessive nitrogen intake results in increased excretion and increased greenhouse gas (GHG) emissions. Supplemental concentrates with the addition of an ionophore given to ruminants grazing wheat is a potential practice for producers to increase nitrogen efficiency while decreasing GHG emissions. Therefore, the objective of this experiment was to quantify the effects of energy (2.95 kg/d) and lasalocid (200 mg/hd/d) supplementation on nutrient intake, energy metabolism, respiratory gas fluxes, and performance of grazing cattle. Methane emissions were not affected (P = 0.58) by treatment, hence methane intensity (P …
