Social media is rapidly changing the way we view the world and live our lives, serving as an online space for connection, creative expression, and inspiration. However, the ever-evolving world of photo editing apps combined with popular health and fitness content on social media sites can be a dangerous combination for young women’s self esteem and body image. This thesis defense explores the ways in which young women are influenced by content that they interact with online. The goal of this project was to provide a general analysis of how fitness and diet-promoting culture on Instagram is affecting young women’s behaviors and perceptions of themselves with an emphasis on the local ASU community. A literature review was conducted as well as an informal survey in order to collect data on the topic and formulate suggestions for alleviating these issues.

At least 30 million people in the United States suffer from an eating disorder during their lifetime (National Association of Anorexia Nervosa and Associated Disorders, 2016). The Centers for Disease Control and Prevention (CDC) defines anorexia nervosa as a disorder where the person strives to maintain a lower than normal body weight through restriction and starvation (CDC MMWR, 1996). People with this disorder constantly have to control and count everything they eat (Mayo Clinic, 2016). For my creative project, I documented my sister's struggles through Digital Storytelling. My hope was to use my creative project to help others who are also struggling with anorexia nervosa. The goal is to provide advice and encouragement based on my family's experiences as well as my sister's accounts of her time in a rehabilitation center. Some of the things that helped my sister through her recovery were patience, support and communication from family and loved ones, caring for animals, and practices with positive self- talk.

The Gluten-Free Diet (GFD) is increasing in prevalence due to increased diagnoses of Celiac Disease, however deficiencies have been found to persist in individuals with Celiac Disease who have been on the diet for a prolonged period of time. These deficiencies are not the result of continued GI inability to absorb the nutrients (as evidenced by biopsy) and, therefore, are inherent to the diet itself. Comparing these deficiencies to nutrient-dense gluten-free grains reveals those that specifically meet the deficiencies evident in the GFD. These include low-fat soy flour, buckwheat, and sorghum as the most nutritionally adequate for the gluten-free individual.

Nutrition instruction has become more accessible; it is no longer relegated to the doctor’s office, dietitian briefing, outpatient clinic, or hospital. Now it is available in people’s hands, pockets, and purses via their smartphone. Since nutrition instruction has become more accessible, health professionals and members of the general public are increasingly interested in using smartphone apps to assist with health-related dietary changes. With more and more of the population required to follow certain dietary recommendations and/or monitor specific nutrient intake, commercially available apps may be a useful and cost-effective resource for the public. The purpose of this four-week intervention was to determine if the popular calorie counter app, MyFitnessPal, can be used to reduce sodium intake to ≤ 2,300 mg/day compared to the traditional paper-and-pencil method. This four-week randomized parallel trial enrolled 30 generally healthy adults who were 18 to 80 years of age. Participants were randomly assigned to the MyFitnessPal (“APP”) group or to the paper (“PAP”) group and required to meet three times with the researcher for screening, baseline (start), and completion of the study. There was a significant difference in the mean urinary sodium change between the APP group and the PAP group from the start of the intervention to the completion (-24.0±32.6 and 8.5±41.9 mmol/g creatinine respectively, p = 0.027). Other positive trends that resulted from the intervention included a decline in dietary sodium in both groups and a higher adherence in the APP group compared to the PAP group regarding recording method. The MyFitnessPal app proved to be a useful tool in reducing and/or monitoring sodium intake. Thus, this trial reinforces the potential of this app to be used for monitoring other nutrients, but further research needs to be conducted.

Objective: The purpose of this randomized parallel arm trial was to demonstrate the effects of daily fish oil supplementation (600mg per day for eight weeks) on body composition and body mass in young healthy women, aged 18-38, at a large southwestern university. Design: 26 non-obese (mean BMI 23.7±0.6 kg/m2), healthy women (18-38y; mean, 23.5±1.1 y) from a southwestern Arizona university campus community completed the study. Subjects were healthy, non-smokers, consuming less than 3.5 oz of fish per week according to self-report. Participants were randomized to one of two groups: FISH (600 mg omega-3 fatty acids provided in one gel capsule per day), or CON (1000 mg coconut oil placebo provided in one gel capsule per day). Body weight, BMI, and percent body fat were measured using a stadiometer and bioelectrical impedance scale at the screening visit and intervention weeks 1, 4, and 8. 24-hour dietary recalls were also performed at weeks 1 and 8. Results: 8 weeks of omega-3 fatty acid supplementation did not significantly alter body weight (p=0.830), BMI (p=1.00), or body fat percentage (p=0.600) as compared to placebo. Although not statistically significant, 24-hour dietary recalls performed at the beginning and end of the intervention revealed a trend towards increased caloric intake in the FISH group and decreased caloric intake in the CON group throughout the course of the study (p=0.069). If maintained, this difference in caloric intake could have physiological relevance. Conclusions: Omega-3 fatty acids do not significantly alter body weight or body composition in healthy young females. These findings do not refute the current recommendations for Americans to consume at least 8 oz of omega-3-rich seafood per week, supplying 250 mg EPA and DHA per day. More research is needed to investigate the potential for omega-3 fatty acids to modulate daily caloric intake.
