This study explores how newspapers framed the weight-loss drugs Xenical®(orlistat) and Alli® (over-the-counter orlistat) during the time period of three months prior to their approvals by the U.S. Food and Drug Administration until one year after each became available on the market. As of June 2011, orlistat is the only weight-loss drug available for long-term use in the U.S. Newspapers are influential sources of information about health issues. Agenda-setting, framing, and priming in news articles can have a powerful effect on public perceptions and behaviors. To conduct the content analysis, researchers first developed a codebook containing variables that described the sources of attribution and the features of each drug. They tested the codebook in a series of pilot tests to ensure inter-rater reliability. The sample of texts for the content analysis, drawn from LexisNexis Academic, contained 183 newspaper articles composed of 85 Xenical articles and 98 Alli articles. The overlap was 25% for inter-rater reliability as well as intra-rater reliability. Frequencies were tabulated using Predictive Analytics SoftWare, version 18.0.3. Results demonstrated that Xenical and Alli were framed differently in some critical ways. For example, there were twice as many quotes from the manufacturer for Alli than for Xenical. Researchers concluded that the reporting on Alli was heavily influenced by the manufacturer's multi-media public relations campaign in the months prior to the market-release date.

Description
In the last five decades, the prevalence of chemicals added to food to enhance its color, texture, flavor, and freshness has increased. These chemicals, known as food additives, are synthetically derived or chemically altered substances that are added to food during processing to achieve a specialized effect. Additives are regulated by the United States Food and Drug Administration and while many are “generally recognized as safe” (GRAS), some emerging research suggests that their safety rulings need to be reexamined.
Considering food additives in one’s diet is of the utmost importance for health, though it can be problematic for those with limited knowledge of additives or nutrition. Common opinion is that good nutrition involves only what is or is not being consumed—calories, fat, etc. But the realm of nutrition depends on quality of food—whole, minimally processed food that subsequently lacks additives—as much as it does the composition of food.
This paper reviews eight of the most common and often problematic food additives in America: high fructose corn syrup, aspartame, sodium nitrate/ sodium nitrite, partially hydrogenated vegetable oil (trans fat), monosodium glutamate (MSG), benzoate preservatives (BHA and BHT), potassium bromate, and caramel coloring. It is important to note that this list is far from comprehensive; these additives receive much attention in America making them some of the most talked about and most easily recognized additives.
This paper aims to present sound depictions of existing research that most often refutes the validity of the “generally recognized as safe” claim currently standing for these food additives, providing consumers with reliable information with which they can make educated decisions when purchasing food and eating healthfully.

Description
This creative project seeks to demonstrate the nutritional and financial benefits of cooking in versus eating out to college age students. We sought to determine what factors significantly differentiated restaurant meals versus home-cooked versions, and how we could share this information with our peers to potentially influence them to make a healthy lifestyle change. The first step was to determine the factors that influence college-aged students eating habits, and was presented with a review of relevant literature in several topics. We researched food literacy in young adults, the impact of fast food, social media's role in healthy eating habits, health behavior change in young adults, and the benefits of home cooking to obtain a general baseline of the knowledge of college-aged students. The initial research was utilized to write more effective blog posts that appropriately addressed our targeted demographic and to determine what platforms would be most appropriate to convey our information. These ideas were taken and then translated into a blog and Instagram account that contained healthy, copycat recipes of popular restaurant meals. We wrote 30 blog posts which were made up of 20 original recipes, 8 nutrition informational posts, and an introduction/conclusion. Finally, a focus group was hosted to ascertain the opinions of our peers, and to determine if they would be willing to make a lifestyle change in the form of cooking more frequently as opposed to eating out regularly. We provided them with a pre and post survey to gather their opinions before and after reviewing the findings of our research and project. We concluded that if given the information in an accessible way, college students are willing to eat in, not out.

Description
Tools designed to help match people with behaviors they identify as likely to lead to a successful behavioral outcome remain under-researched. This study assessed the effect of a participant-driven behavior-matching intervention on 1) the adoption of a new behavior related to fruit and vegetable (F&V) consumption, 2) study attrition, and 3) changes in F&V consumption. In this two-arm randomized controlled trial, 64 adults who did not meet standard F&V recommendations were allocated to an intervention (n=33) or control group (n=31). Participants in the intervention group ranked 20 F&V-related behaviors according to their perceived likelihood of engagement in the behavior and their perception of the behavior’s efficacy in increasing F&V consumption. Participants in the intervention group were subsequently shown the list of 20 behaviors in order of their provided rankings, with the highest-ranked behaviors at the top, and were asked to choose a behavior they would like to perform daily for 4 weeks. The control group chose from a random-order list of the same 20 behaviors to adopt daily for 4 weeks. During the study period, text messages were sent to all participants 90 minutes before their reported bedtime to collect Yes/No data reflecting successful behavior engagement each day. The binary repeated-measures data collected from the text messages was analyzed using mixed-effects logistic regression, differences in attrition were assessed using log-rank analysis, and change scores in F&V consumption were compared between the two groups using the Man-Whitney U test. P<0.05 indicated significance. The rate of successful behavior adoption did not differ significantly between the two groups (b=0.09, 95%CI= -0.81, 0.98, p=0.85). The log rank test results indicated that there was no significant difference in attrition between the two groups (χ2=2.68, df=1, p=0.10). F&V consumption increased significantly over the 4 weeks in the total sample (Z=-5.86, p<0.001), but no differences in F&V change scores were identified between the control and intervention groups (Z=-0.21, p=0.84). The behavior-matching tool assessed in this study did not significantly improve behavior adoption, study attrition, or F&V intake over 4 weeks.

Description
A large amount of research associates the lack of fruit and vegetable consumption and the intake of animal-based foods with poor health outcomes. Making shifts towards a plant-focused diet could benefit the health of individuals. Individuals who show the highest long-term adherence to the avoidance of animal-based foods are those who value animal welfare. PURPOSE: The primary purpose of this study is to explore the validity of a novel animal food frequency questionnaire (AFFQ) in relation to dietary animal food intake using 3-day dietary food logs and measuring potential renal acid load (PRAL). PRAL is the amount of acid that is produced by the body after digesting food. Fruits and vegetables produce a lower acid load, which is reflective of positive health outcomes. A secondary aim of this study is to explore the relation between AFFQ scores and measures of empathy. METHODS: Participants complete a 10-minute survey including the AFFQ and the BES-A. The Basic Scale of Empathy for adults will be viewed based on the 2 factor and 3 factor analysis assessing: Affective empathy, Cognitive empathy, Emotional contagion, and Emotional Disconnection. The AFFQ will be scored and correlated with the 3-day food log and PRAL to explore validity of the new AFFQ scale. Secondarily, the AFFQ will be scored and correlated with the BES-A to explore an association. RESULTS: The null hypotheses H01 and H02 were rejected. H01 showed that AFFQ correlates significantly with percentage of dietary protein coming from animal- based products (r=.676, p=.016). H02 showed AFFQ has a significant correlation to PRAL (r=.831, p<.001). PRAL and the percentage of protein in the diet coming from animal-based products have a significant correlation (r=.725, p=.008). The null hypothesis H03 was accepted with AFFQ and BES-A 2 factor and 3 factor’s correlations showing (r= -.412, p=.183) and (r= -.307, p=.332). CONCLUSION: The AFFQ was able to reflect differences in frequency of animal-based food intake among the convenience sample. The AFFQ and individuals’ food choices were not related to their empathy levels.

Description
The health of the planet and its people face considerable challenges; the climate faces threats of irreversible damage while chronic disease and obesity rates continue to rise. Both issues can be attributed in part to humanity’s poor treatment and attitude towards food. Humans throw away much of the nutritious food available, resulting in unhealthful diets and considerable amounts of food waste, leading to harmful greenhouse gas emissions. The current solutions for improving the separate matters of planetary and human health include tradeoffs between the two, despite their interrelatedness. Paradoxically, current research shows that increased fruit and vegetable intake is associated with increased food waste. Current literature has not emphasized a focus on interventions aimed to improve diet quality and food waste simultaneously.Recent research shows that mindfulness can have impacts on human health, such as in relation to chronic pain, mental wellbeing, and self-awareness. Mindful eating specifically has demonstrated improvements in disordered eating behaviors and relationship with food. Yet, no research has been conducted to explore mindful eating in relation to healthful and efficient relationships with food. Therefore, the present study explores mindfulness as a mechanism to improve diet quality and reduce food waste.
The protocol presented in the study, titled Mindful Waste Watchers (MWW), was a 4-week novel virtual program incorporating nutrition education, household food waste reduction education, and mindfulness/mindful eating exercises into each lesson. Entry, exit, and 4-week follow-up surveys, each identical, were distributed to participants to assess diet quality, household food waste habits, mindful eating, mindfulness, and food appreciation, primarily by utilization of validated scales.
The two primary outcomes evaluated in the present article were diet quality and household food waste behaviors. It was found that the intervention did not produce significant effects for either parameter, suggesting that the protocol was not feasible. However, a significant positive effect was found for food appreciation, a factor that may show promise in future research. While no significant effects were found for the primary outcomes, the findings of this study can be considered in future research targeted towards discovering effective interventions to improve diet quality and reduce household food waste.

Description
Gastrointestinal (GI) complaints are prevalent among athletes. Fermented foods with pre-or probiotic features may relieve GI symptoms by improving gut health. This study aimed is to examine the impact of a nutritional supplement containing fermented whey protein with Galacto-oligosaccharide (GOS) fiber on GI distress among well-trained athletes over time by analyzing self-reported GI complaints without a control group. This quasi-experimental clinical trial consisted of a 3-week baseline period, reflected by two baseline measurements on Day 1 and Day 22, which was followed by a 3-week intervention period, reflected by a post-intervention measurement on Day 43, in which athletes added 15g of a fermented whey protein product to their diet. The primary outcome was based on the self-reported gastrointestinal symptom rating scale (GSRS), and the secondary outcome was based on a daily questionnaire, in which daily GI complaints and exercise occurrences were reported. Tertiary outcomes included a 24-hour diet recall (ASA24) and self-reported diet quality (REAP). Outcomes obtained during baseline (Day 1 and Day 22 average) were compared to those post-intervention (Day 43). Statistical significance was set at P<0.05. A total of n=50 athletes (24.7±4.5 years) with GI issues were included in the study. Five individual items of the GSRS including abdominal pain, acid reflux, bloating, burping, and loose stools reflected significantly lower scores on Day 43 in comparison to baseline (P≤0.028). A total of 78% reported GI complaints at baseline, and 61% of the participants reported lower GI complaints on Day 43 after supplementation in comparison to baseline (P=0.004). Further research is needed to explore the potential benefits of a hydrolyzed and fermented whey protein with prebiotics in a more controlled setting among athletic populations.

Sleep is an essential biological requirement to sustain human life and a critical component for athletes. There has been a rising trend for poor sleep in the general population and the problem persists as well within the athletic population. Research has demonstrated numerous benefits of optimized sleep on athletic performance and athlete wellness. Further investigation of potential dietary strategies to improve self-perceived sleep quality is warranted. This study examined the differences in perceived sleep quality and wellness between a 3-week baseline period and after a 3-week supplementation period, in which participants consumed a dietary supplement containing fermented whey protein + galacto-oligosaccharides (GOS) + casein protein daily. Validated questionnaires, namely, Athens Insomnia Scale (AIS), Physical Health Questionnaire (PHX), Kessler-6 Mental Stress Scale (K6) were used to measure perceived sleep quality and wellness on Day 1, Day 22 and Day 43. Additionally, multiple 24-h dietary recalls (ASA24), and food quality using the validated Rapid Eating Assessments for Participants (REAP) questionnaire, were used to assess dietary patterns throughout the study, while exercise occurrence was tracked through a self-developed daily questionnaire. A total of 54 healthy active adults (age=18-35yrs) experiencing gastro-intestinal (GI) complaints were included in the trial, and 50 participants were included in the final analysis. Significantly lower AIS-8 total scores were found on Day 43 compared to Day 22 while controlled for Day 1 (Day 43: 4.36 ± 3.68 versus Day 22: 5.02 ± 4.11, F=4.379 (1, 50), p=0.042), while no differences were found for wellbeing (p≥ 0.180). Dietary intake, food quality and exercise frequency did not change over time (p≥0.080). These results suggested that a daily protein + GOS supplement was associated with a decrease in AIS-8 total scores suggesting improved perceived sleep quality among athletes after 3 weeks. A controlled research study should confirm these results in the future. More research is required to assess the effects of protein + prebiotic supplementation on sleep parameters among athletes.
