The Antioxidant Content Of Wong Lo Kat Tea, Valerie Kwong

Theses, Dissertations and Culminating Projects

Wong Lo Kat (or Wanglaoji in Mandarin) is a popular soft drink containing herbal tea that is often used as a Chinese folk remedy for mild ailments. The herbs included in the drink are the following: Chinese Mesona, White Frangipani, Microcos, Chrysanthemum, Japanese Honeysuckle, Heal All, and Chinese Licorice. While there is research on the individual plants, there is limited information on the combined mixture of the herbs included in the Wong Lo Kat drink, particularly in published English literature. Antioxidant content for the individual herbs and a combined mixture of equal parts of each herb was tested using the …

Effect Of Whole Fruit Based Anthocyanins On Systemic Inflammation, Oxidative Stress, And Waist Circumference In Women, Anastasiya Yudinova

Cal Poly Humboldt theses and projects

Cardiometabolic disease (CMD) remains the leading cause of death nationally. Intra-abdominal fat (IAF) is one of the primary risk factors for CMD. Women are particularly vulnerable to developing CMD due to hormonal changes during and after menopause that increase IAF. Excess IAF has deleterious effects on the body, increasing systemic inflammation and oxidative stress, leading to CMD. This systematic review and meta-analyses examined current research related to consumption of whole foods high in anthocyanins, their impact on oxidative stress and inflammation, and the medium and amount of anthocyanin delivery that yields the most benefits to women at risk for CMD. …

The Effect Of Sodium Selenate Biofortification On Plant Yield, Mineral Content, And Antioxidant Capacity Of Culinary Herb Microgreens, Rachel G. Newman

Graduate Theses, Dissertations, and Problem Reports

Selenium (Se) biofortification of plants has been suggested as a method for enhancing dietary Se intake. Popular herbs such as basil (Ocimum basilicum), cilantro (Coriandrum sativum), and scallions (Allium fistulosum) are used for enhancing flavors. Microgreens are young seedlings harvested with one to two true leaves and are increasingly popular in the consumer marketplace. In this study, basil, cilantro, and scallion microgreens were treated with various concentrations of Se as sodium selenate in hydroponic conditions to investigate the effect on plant yield, mineral content (selenium, sulfur, sodium, potassium, phosphorus, calcium, magnesium, copper, iron, manganese, zinc, and boron), total phenolic compounds, …

Understanding Lipid Oxidation In Low-Moisture Food, Leann M. Barden

Doctoral Dissertations

Low-moisture snacks account for much of the saturated fat in the diet, making them a key target for improving consumers’ health. However, it is not currently feasible to maintain the same shelf life when replacing saturated fats with unsaturated fats in these products. The first study characterized the microstructure of a low-moisture cracker model system and determined the impact of iron, chelators, and free fatty acids (FFA) on lipid oxidation kinetics. Confocal microscopy showed that lipids form a continuous layer surrounding the small and/or minimally gelatinized starch granules. Lipid-starch, lipid-air, and starch-lipid-protein interfaces all existed. Oxidation studies showed a large …

Honesty And Carotenoids In A Pigmented Female Fish, Alexandria Christine Brown

Doctoral Dissertations

The carotenoid tradeoff hypothesis states that diet-derived carotenoids are tradedoff among competing physiological demands, but this statement is rarely tested in ornamented females. The following dissertation tests the carotenoid tradeoff hypothesis in reverse sexually dimorphic convict cichlids (Amantitlania siquia) using carotenoidsupplemented diet treatments and a field-based study of carotenoid intake. Spectral, microscopic, and chemical analysis determined how females allocated the pigments to tissues and how those decisions affected their ventral patch coloration. The results presented in the current study show that carotenoids enhance offspring growth and survival, lower oxidative stress, and reduce the time to clear a parasite. The two …

Estimation Of The Number Of Days Required To Determine Usual Antioxidant Intakes And Assessment Of The Prevalence Of Nutrient Inadequacy Among College Students, Catherine G. Davis

Master's Theses

High intake of antioxidant rich foods has been shown to decrease risk factors of chronic disease. Young adulthood may be crucial in establishing healthy lifestyles including adequate nutrient consumption.

The present study was designed 1) to estimate usual nutrient intakes, 2) to calculate the number of days required to estimate usual antioxidant intake, and 3) to assess intake adequacy from diet and diet + supplement sources by using the Estimated Average Requirement (EAR). The USDA Flavonoid and Proanthocyanidin databases, food consumption data, and dietary supplement use data from 60 students aged 18-25 years at the University of Connecticut were utilized. …

Antioxidant Assessment In Western Maine Elderly Women Following 30 Days Of Wild Blueberry Consumption, John David Bagnulo

Electronic Theses and Dissertations

Increased fruit and vegetable consumption is the single most protective characteristic of a diet against disease. While the exact mechanism by which this protection is offered remains unclear, the leading theory is centered on the antioxidant content of fruits and vegetables. Recent studies have shown that certain fruits and vegetables have significantly higher antioxidant contents than others. Wild North American blueberries (Vaccinium angustifolium) have one of the highest antioxidant contents of all h i t s and vegetables tested. This thesis investigates the relationship between the consumption of blueberries and blood antioxidant levels in 24 elderly women. In addition, fruits …

Antioxidants And Alcohol In The Progression Of Acquired Immunodeficiency Syndrome, Laura Lynne Prestwich

Undergraduate Honors Capstone Projects

Wasting syndrome in acquired immunodeficiency syndrome (AIDS) appears to play a role in decline of immune function. Along with poor appetite, HIV infected individuals seem to have a tendency to be heavy alcohol drinkers which may be immunosuppressive and cause malnutrition. Altered macronutrient metabolism visibly contributes to wasting; however, micronutrient deficiencies also appear to play a role. Micronutrient deficiency has also been known to decrease immune function. As part of their role as antioxidants, P-carotene, vitamin C, vitamin E, and selenium may be helpful in altering cell production and response to cytokines and other secretions. This may decrease viral replication …
