Cardiovascular disease has reached epidemic proportions resulting in its ranking as the number one cause of mortality in the Western world. A key player in the pathophysiology of vascular disease is oxidative stress due to free radical accumulation. This intervention study was conducted to evaluate any potential mediation of oxidative stress using a soil-derived organometallic compound (OMC) with suspected antioxidant properties. A 10-week study was conducted in male Sprague-Dawley rats (n = 42) fed either a high-fat diet (HFD) consisting of 60% kcal from fat or a standard Chow diet containing only 6% kcals from fat. Rats from each diet …

Long-term results of dietary weight loss interventions are not promising, with rates of weight loss maintenance at a mere 20%. Psychological factors related to weight maintenance include setting unrealistic weight goals, poor problem-solving skills, low self-efficacy, dichotomous thinking, and external locus of control. The ability to maintain a stable bodyweight over time has been associated with optimal health outcomes, lower stress levels, and higher general well-being. Dichotomous thinking has been associated with overeating and increased bodyweight. Cognitive restraint, disinhibition, and hunger are three dimensions of human eating behavior that appear to be important to understanding weight loss maintenance. Individuals who …

Multiple health-related benefits have been associated with adherence to plant-based diets, including vegan, vegetarian, and pescatarian dietary patterns. Despite a consistent body of evidence on the importance of healthy diets, Americans continue to find difficulty in establishing and adhering to dietary goals that could elicit long-term health benefits. Recent research suggests an important role for goal-setting strategies in health behavior change attempts, with some success shown in dietary behavior change, specifically. The current study thus aimed to explore whether having multiple goals alongside one primary goal of following a vegetarian, vegan, or pescatarian diet would increase the achievability of that …

Background: Healthy eating plays critical roles in the prevention of many chronic diseases, but there are many barriers in life that prevent people from adopting and maintaining healthy diets. Thus, identifications of barriers that people perceive they have in trying to eat healthy can guide the strategies for dietary behavior change interventions by taking account of the barriers. Objective: The purpose of this study was to identify and quantify the perceived barriers to healthy eating (PBHE), to investigate the relationship between socioeconomic factors and PBHE, and to explore the associations between PBHE and dietary intake among parents of elementary-school aged …

Background: Twenty-four hour urinary sucrose and fructose (24uSF) has been developed as a dietary biomarker for total sugars intake. Collection of 24-h urine is associated with high costs and heavy participant burden, while collection of spot urine samples can be easily implemented in research protocols. The aim of this thesis is to investigate the utility of uSF biomarker measured in spot urine. Methods: 15 participants age 22 to 49 years completed a 15-day feeding study in which they consumed their usual diet under controlled conditions, and recorded the time each meal was consumed. Two nonconsecutive 24-hour urines, where each urine …

Although past literature has examined the prevalence of campus food pantries, most have not examined student satisfaction of campus food pantries the acceptability and feasibility of the campus food pantries in the U.S. This descriptive and quasi-experimental study assessed the acceptability and feasibility of campus food pantry intervention on two campuses (Downtown Phoenix and Tempe) at Arizona State University (ASU). The acceptability measures were composed of 30 survey questions including demographics, satisfaction survey, and food insecurity questionnaires, which were abstracted from the U.S. Adult 10-Item Food Security Survey Module. The food pantry was open once a week at each site. …

To date, there have not been any studies in a human population that explore the potential of vinegar ingestion in reducing visceral fat, a common yet serious metabolic disease risk factor. However, previous research in animal models exhibit promising findings, showing that vinegar is effective at reducing visceral fat. This is thought to be due to the activation of AMPK (adenosine monophosphate protein kinase) by acetic acid, the active ingredient in vinegar. The purpose of this study was to identify if this potentially groundbreaking relationship exists in human subjects. Healthy, nonsmoking, sedentary adults between the ages 18-45 y and a …

Water makes up about 45-70% of a human body's total weight. It is estimated that 80% of the human brain's tissue is composed of water. Cognitive productivity is altered when the body is in a mere 2% dehydrated state. Several cognitive functions impacted by dehydration include: visual motor tracing, short-term recall, attentiveness, and mathematic efficiency. It is estimated that 80% of the U.S. adult population endures the majority of their day in a mildly dehydrated state. Participants were employees working full-time jobs with Arizona State University or Tri Star Motor Company. Employees had to be 18 or older were invited …

Fruit and vegetable consumption among school children falls short of current recommendations. The development of Public-Private Partnerships (PPP), which combine the resources of government entities with the resources of private entities, such as businesses or not-for-profit agencies, has been suggested as an effective approach to address a number of public health concerns, including inadequate fruit and vegetable consumption. The United States Department of Agriculture's (USDA) Fresh Fruit and Vegetable Program (FFVP) provides fruits and vegetables as snacks at least twice per week in low-income elementary schools. In addition to increasing fruit and vegetable consumption behaviors at school, children participating in …

Vegetarian diets can provide an abundance of nutrients when planned with care. However, research suggests that vegetarian diets may have lower protein quality than omnivore diets. Current protein recommendations assume that vegetarians obtain a majority of their protein from animal products, like dairy and eggs. Studies have shown that this assumption may not be valid. The recommended dietary allowance (RDA) may not be adequate in vegetarian populations with high protein requirements. The purpose of this study is to analyze dietary protein quality using the DIAAS (Digestible Indispensable Amino Acid Score) method in both vegetarian and omnivore endurance athletes. 38 omnivores …
