Background. Despite research aimed at understanding the mechanisms of essential hypertension, instances of this condition continue to rise. Recent findings indicate that the administration of dietary nitrates, in the form of beetroot juice and other nitrate-rich vegetables, may offer anti-hypertensive effects in various study populations. Objective. This randomized, placebo-controlled, crossover trial sought to compare the effects of high-nitrate vegetable salads to the effects of low-nitrate canned vegetables on plasma nitrate/nitrite concentration, peripheral and central-aortic systolic and diastolic blood pressures, pulse wave velocity, and flow-mediated dilation. Methods. Healthy, post-menopausal women (n=5; 80% Caucasian; 52.6 ± 5.7 years) with mildly elevated blood …

Currently, there has been limited research on evaluating the social media use and competency level of registered dietitian/nutritionists (RD/N). With health information increasingly sought on social media, it is imperative to understand the social media competency of health professionals. The social media use, reach, and competency level of a nationwide RD/N sample was assessed utilizing an online survey. The sample (n=500) while mostly female (97%) was representative of RD/Ns compared to the nationwide statistics from the Commission on Dietetic Registration. The sample included RD/Ns from forty-six states with California (n=44), New York (n=42), and Texas (n=34) having the largest proportion …

Background: Acetic acid in vinegar has demonstrated antiglycemic effects in previous studies; however, the mechanism is unknown. Objective: To determine whether acetic acid dissociates in the addition of sodium chloride and describe a flavorful vinaigrette that maintains the functional properties of acetic acid. Design: Phase I - Ten healthy subjects (23-40 years) taste tested five homemade vinaigrette and five commercial dressings. Perceived saltiness, sweetness, tartness, and overall tasted were scored using a modified labeled affective magnitude scale. Each dressing was tested three times for pH with a calibrated meter. Phase II – Randomized crossover trial testing six dressings against a …

Birds have shown promise as models of diabetes due to health and longevity despite naturally high plasma glucose concentrations, a condition which in diabetic humans leads to protein glycation and various complications. Research into mechanisms that protect birds from high plasma glucose have shown that some species of birds have naturally low levels of protein glycation. Some hypothesize a diet rich in carotenoids and other antioxidants protects birds from protein glycation and oxidative damage. There is little research, however, into the amount of protein glycation in birds of prey, which consume a high protein, high fat diet. No studies have …

Exclusivity and duration of breastfeeding and the provision of human milk in the United States is suboptimal. In the absence of adequate banked donor human milk for distribution to all infants in need, many families choose to engage in the practice of Private Arrangement Milk Sharing (PAMS), partially facilitated through social media, to procure human milk for their infants. Evidence regarding the participant and infant characteristics and risk abatement practices is incomplete. This dissertation describes and explores the characteristics of recipient participants and infants, family constellation, donor screening practices, and related risk abatement strategies. Data was collected via on-line survey …

Mobile healthy food retailers are a novel alleviation technique to address disparities in access to urban produce stores in food desert communities. Such retailers, which tend to exclusively stock produce items, have become significantly more popular in the past decade, but many are unable to achieve economic sustainability. Therefore, when local and federal grants and scholarships are no longer available for a mobile food retailer, they must stop operating which poses serious health risks to consumers who rely on their services. To address these issues, a framework was established in this dissertation to aid mobile food retailers with reaching economic …

Abstract Healthy eating promotes the optimal growth and development of children and can help reduce the risk of developing many health-related problems such as obesity and diabetes in both children and adults. Low-income, minority children disproportionately suffer from several chronic diseases when compared to middle to upper class non-Hispanic whites. The school is an environment in which children can learn about the importance of healthy eating by observing foods served, observing role models and interacting with a curriculum that emphasizes health and good nutrition. Parent involvement has been shown to play a role in improving health habits of children. Therefore, …

ABSTRACT Objective: The purpose of this randomized parallel two-arm trial was to examine the effect that an intervention of combining daily almond consumption (2.5 ounces) with a walking program would have on heart rate recovery and resting heart rate when compared to the control group that consumed a placebo (cookie butter) in men and postmenopausal women, aged 20-69, in Phoenix, Arizona. Design: 12 men and women from Phoenix, Arizona completed an 8-week walking study (step goal: 10,000 steps per day). Subjects were healthy yet sedentary, non-smokers, free from gluten or nut allergies, who had controlled blood pressure. At week 5, …

The winter holiday period has been highlighted as a major risk period for weight gain due to excess caloric intake in the form of fat and sugar. Furthermore, diets high in fat and sugar have been implicated in the pathogenesis of diabetes and cardiovascular disease. Exercise aids in the prevention of weight/fat gain, and prevents deleterious changes in cardiometabolic function. The objective of this study was to examine the effects of a fat-sugar supplemented diet, with and without two different exercise training protocols, on body composition, glycemic control and other markers of cardiovascular disease in an at-risk population of overweight …

Background: College freshmen are exposed to a variety of environmental and social factors that can alter changes to health habits and encourage weight gain. Weight-related conversations had with friends may be related to self-perception of weight and alterations to health behaviors, but this association has yet to be assessed in the college population. Objective: This study aims to examine the relationship between friend advice about weight management, self-perception of weight, and alterations to weight change intentions, physical activity, and eating habits in college freshmen over time. Methods: College freshmen from ASU with complete data for three time points (n=321) were …
