In Vitro Fermentation Patterns Of Rice Bran Components By Human Gut Microbiota, Tung Minh Pham Aug 2016

In Vitro Fermentation Patterns Of Rice Bran Components By Human Gut Microbiota, Tung Minh Pham

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 ...


Rice Consumption And Effects Of Rice Cake, Seolgitteok, On Human Health, Ellen Joy Pottgen Aug 2016

Rice Consumption And Effects Of Rice Cake, Seolgitteok, On Human Health, Ellen Joy Pottgen

Theses and Dissertations

Within the United States type 2 diabetes is an ever growing health epidemic. The prevalence in the adult population has quadrupled over the past 30 years and is expected to continue on a similar path in the coming decades. While the cause of type 2 diabetes is multifactorial, it is considered to be an acquired condition related to environmental contributors including poor diet, obesity, and physical inactivity, which may be managed to alter the course or progression of the disease. Preventative or maintenance measures emphasize nutritional intervention strategies, including encouraging individuals to follow a nutrient-dense, high-fiber diet with ample whole-grains ...


The Effect Of Protein Quantity And Quality At Breakfast On Energy Metabolism, Appetite And Metabolic Health, Brianna Lynne Neumann May 2016

The Effect Of Protein Quantity And Quality At Breakfast On Energy Metabolism, Appetite And Metabolic Health, Brianna Lynne Neumann

Theses and Dissertations

Obesity is a global health concern and, within the United States, the current obesity rate is 36% and projected to double within the next two decades. Obesity is linked to many chronic diseases such as cancer, heart disease and type 2 diabetes. In young females, weight gain (5-11 kg) between the ages of 20-30 years increases the risk of developing type 2 diabetes and cardiovascular disorders later in life. The cause of obesity is multifactorial in nature, however fundamentally weight gain occurs when energy intake is greater than energy expended (i.e. calories in > calories out). Therefore, identifying and validating ...


Comparative Efficacy Of Foaming And Non-Foaming Handsoap In Reduction Of Microorganisms In Handwashing, Danielle Marie Conover May 2016

Comparative Efficacy Of Foaming And Non-Foaming Handsoap In Reduction Of Microorganisms In Handwashing, Danielle Marie Conover

Theses and Dissertations

Handwashing (HW) is a long established method to prevent disease transmission. Ensuring effectiveness of current HW methods is essential for optimal HW and enhanced disease prevention. The objectives of this research were to 1) conduct a survey of soap type and volume in food service establishments in Washington County, Arkansas; 2) investigate how soap type impacts HW behavior; and 3) determine the difference in microbial reduction between foaming (F) and liquid (L) handsoap. For Objective 1, food service establishments in Washington County, AR were selected based on exclusion criteria and random number generations, and handsoap samples were collected to determine ...


Effects Of Soybean Pectin On Blood Glucose And Insulin Responses In Healthy Men, Melissa Ann Jones Jul 2015

Effects Of Soybean Pectin On Blood Glucose And Insulin Responses In Healthy Men, Melissa Ann Jones

Theses and Dissertations

The goal of this study was to examine the effects of soy pectin on postprandial plasma glucose and insulin responses in healthy adult males␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣␣ intestinal microbiota to determine if differences in weight or body mass index would be linked to differences in microbiota populations. Pectin is a soluble fiber with demonstrated health benefits such as the ability to lower blood glucose and cholesterol, increase satiety leading to lower caloric intake, improve insulin resistance and lower inflammation. These benefits suggest that pectin may help in prevention and treatment of type II diabetes. Soy pectin is extracted from hulls, a waste product ...


Preferences And Nutrient Composition: The Impact Of Flour Types On Battered Fried Food, Lobat Siahmakoun Jul 2015

Preferences And Nutrient Composition: The Impact Of Flour Types On Battered Fried Food, Lobat Siahmakoun

Theses and Dissertations

This study investigated the impact of different flour-batter types on protein rich food in regard to people’s overall liking and sensory preferences (saltiness, flavor, texture, moisture, and color). In addition, all battered fried chicken, fish, shrimp, pork, and beef were analyzed for fat, calories, and protein content in the Central Analytical Laboratory at the University of Arkansas. Two hundred thirty-five participants completed the questionnaire containing five major sections. Respondents evaluated samples of battered fried chicken, fish, shrimp, pork, and beef using all-purpose flour (APF), rice-flour (RF), and potato flour (PF). Data was analyzed using binomial analysis and paired sample ...


Effect Of Functional Starch In Brown Rice And Grain Sorghum On Plasma Glucose And Insulin Responses In Humans, Nicole Marie Poquette Dec 2013

Effect Of Functional Starch In Brown Rice And Grain Sorghum On Plasma Glucose And Insulin Responses In Humans, Nicole Marie Poquette

Theses and Dissertations

Diabetes and obesity are chronic illnesses increasing at dramatic rates in the U.S. and around the world. Research has looked to prevent or control diabetes and obesity through functional ingredients such as healthy-dietary carbohydrates to control blood glucose levels. Starch is a principle carbohydrate, which influences blood glucose levels, and measuring starch digestibility fractions can help predict the glucose response in the body. The objectives of this study were to investigate the functional starch content of parboiled brown rice flour and grain sorghum flour, and measure the effects on postprandial plasma glucose and insulin levels of 14 and 10 ...


The Role Of Antioxidant Rich Berries In The Prevention Of Postmenopausal Bone Loss, Lydia Karimi Kaume Aug 2012

The Role Of Antioxidant Rich Berries In The Prevention Of Postmenopausal Bone Loss, Lydia Karimi Kaume

Theses and Dissertations

Postmenopausal osteoporosis is the most prevalent form of osteoporosis and results in fragility fractures. Smoking is one of the major risk factors for osteoporosis and is known to aggravate bone loss in postmenopausal women due to increased oxidative stress and inflammation. Diet-based interventions using berries have shown bone protective affects in animal studies partially due to antioxidant and anti-inflammatory properties of their phenolic compounds. The goal of this research was to determine the effects of antioxidant-rich fruits in the prevention of postmenopausal bone loss. Our first study examined the dose dependent effects of blackberries in preventing bone loss in an ...


Can Antioxidant-Rich Berries Improve Risk Factors Associated With Cardiovascular Disease In Postmenopausal Smokers?, Jordan Alaine Teeple Dec 2011

Can Antioxidant-Rich Berries Improve Risk Factors Associated With Cardiovascular Disease In Postmenopausal Smokers?, Jordan Alaine Teeple

Theses and Dissertations

The purpose of this study was to examine the effects of smoking on risk factors associated with cardiovascular disease (CVD) and determine the efficacy of antioxidant-rich berries in ameliorating these risk factors in postmenopausal smokers. Menopause and cigarette smoking have been identified as major risk factors for CVD due to a decrease in antioxidant protection, increase in inflammation and oxidative stress, and adverse changes in serum lipids. Antioxidants, specifically flavonoid compounds found in blackberries and blueberries, have been shown to prevent low-density lipoprotein cholesterol oxidation and thus prevent downstream inflammation and oxidative stress. Healthy, postmenopausal nonsmokers (n=14) and smokers ...


Effect Of Soyasaponin Fractions On Human Colon Cancer Cells, Joseph Tyler Salyer Dec 2011

Effect Of Soyasaponin Fractions On Human Colon Cancer Cells, Joseph Tyler Salyer

Theses and Dissertations

Group B saponins, the predominant form of saponins in heat-treated soy products, have been shown to possess hypocholesterolemic, antimutagenic, and anticarcinogenic properties. Previous studies have evaluated crude mixtures of soyasaponins, but studies evaluating a single purified soyasaponin as an anticarcinogenic agent are limited. The goal of this study is to examine the effects of purified soyasaponins I and III as well as their aglycone form, soyasapogenol B, as anticarcinogenic agents on the human colon adenocarcinoma cell line Caco-2. Experiments were conducted to determine the effects of purified soyasaponins on cell proliferation, Protein Kinase C (PKC) activity, and cell morphology in ...
