Introduction: A diet high in fermented, oligio-, di-, monosaccharide, and polyols (FODMAP) has been shown to exacerbate symptoms of irritable bowel syndrome (IBS). Previous literature has shown significant improvement in IBS symptoms after adherence to a low FODMAP diet (LFD). However, dietary adherence to the LFD is difficult with patients stating that information provided by healthcare providers (HCPs) is generalized and nonspecific requiring them to search for supplementary information to fit their needs. Notably, studies that have used a combination of online and in-person methods for treatment have shown improved adherence to the LFD. Objective: To determine whether a novel …

The Adequate Intake (AI) level for total fiber for adults is 14 grams per 1,000 kilocalories per day; however, only 12.9% of Americans met their total fiber needs according to the 2015-2016 National Health and Nutrition Examination Survey (NHANES). A lower frequency of home-cooked meals and a higher frequency of restaurant meals have been cited as a possible explanation for the low dietary fiber intake among Americans, and according to the Social-Ecological Model, the retail food environment can influence our food choices such as the choice to eat at home or eat out. The objective of this study is to …

This study aimed to investigate the effects of specific macronutrient feedings on competitive golf performance and perceived levels of fatigue and alertness. Participants played three, nine hole rounds of golf, consuming an isocaloric beverage as a control (CON), with the addition of carbohydrate (CHO), or combination of protein and carbohydrate (COM). Physiological and performance measurements were taken before, during, and following each nine hole round. Performance measurements include driving accuracy (DA), driving distance (DD), iron accuracy (IA), chipping accuracy (CA), and putting accuracy (PA). Pre-golf hydration status (urine specific gravity [USG]) and Sweat Rate during golf performance showed no significant …

Objectives. This study primarily explored the relationship between family meal frequency and youth intake of fruits and vegetables (FV) and added sugar from sugar-sweetened beverages (SSBs) in a population of Latinx parents and their middle school children. The study secondarily explored factors influencing family meal frequency; specifically, whether parent education level, income level, acculturation level, and food insecurity are associated with family meal frequency. Methods. Latinx parents and their 6th-8th grade children were recruited from eligible middle schools in Maricopa County to participate in a larger intervention study. A sample of parent-youth dyads from the first cohort of the larger …

Objective: Migration to the United States (U.S.) has been associated with food insecurity and detrimental changes in diet quality. How these changes affect women in context of their neighborhood food environment has not been thoroughly explored. This study aimed to assess if food security is associated with diet quality and to explore if perceived food availability moderates this purported association in a sample of Mexican immigrant women. Methods: Mexican-born women (n=57, 41±7 years) residing in the U.S. for more than 1 year self-reported food security status, monthly fast-food frequency, and their perception of fruit, vegetables, and low-fat product availability within …

Oral contraceptives are one of the most frequently used forms of birth control among young women. However, research has shown that this type of medication can contribute to negative changes in mood and diminished vitamin status. In particular, women taking oral contraceptives are at an increased risk of vitamin B6 deficiency due to changes in enzyme activity with estrogen intake. Depressed mood is one of the known symptoms of vitamin B6 deficiency as this vitamin acts as an essential cofactor in converting tryptophan to the neurotransmitter, serotonin. Lack of adequate levels of vitamin B6 therefore contribute to decreased production of …

More than 200 hikers are rescued annually in the greater Phoenix area. This study examined the impact of hiking in hot (HOT), dry temperatures versus moderate (MOD) temperatures on dietary intake behaviors as well as markers of heat stress. Twelve recreational mountain hikers climbed “A” Mountain four consecutive times (4-miles) on a HOT day (WBGT=31.6 °C) and again on a MOD day (WBGT= 19.0 °C). Simulated food and fluid behavior allowed participants to bring what they normally would for a 4- mile hike and to consume both ad libitum. The following heat stress indicators (mean difference; p-value), were all significantly …

Background. Despite extensive research in the literature aimed at understanding the role of hypertension as a major risk factor for numerous leading causes of death in the United States, rates of this disease continue to rise. Recent findings suggest that antiseptic mouthwash use may increase blood pressure through elimination of oral bacteria that facilitate the enterosalivary nitrate-nitrite-nitric oxide pathway. Objective. The purpose of this randomized, controlled, crossover trial was to examine the effects of antiseptic mouthwash use and sodium intake on blood pressure and salivary nitrate levels in prehypertensive adults. Methods. Healthy adults (n=10; 47.3±12.5) with mildly elevated blood pressure …

Healthy lifestyle behaviors including quality nutrition have been shown to successfully prevent chronic disease or minimize symptoms. However, many physicians lack the knowledge and skills to provide adequate nutrition counseling and education for their patients. A major component of this problem is that medical schools are not required to teach nutrition education. The purpose of this feasibility study was to compare the changes in the perceived importance of nutrition in the medical field in medical students before and after participating in a week-long interactive nutrition course in order to determine if a week-long course can positively influence students’ perceptions of …

Chronic diseases, such as diabetes, heart disease, and cancer are leading causes of death in the United States. Although they result from a host of personal and environmental factors, diet remains a critical way to reduce the risk. Plant-based diets in particular are associated with reduction in risk for chronic disease due to an intake that closely mirrors the Dietary Guidelines for fruit and vegetable consumption, fiber, and fat intake. Additionally, plant-based diets offer a sustainable alternative in relation to food production as they often require fewer natural resources overall. While there are many benefits to following a plant-based diet, …
