Description
There are several visual dimensions of food that can affect food intake, example portion size, color, and variety. This dissertation elucidates the effect of number of pieces of food on preference and amount of food consumed in humans and motivation for food in animals. Chapter 2 Experiment 1 showed that rats preferred and also ran faster for multiple pieces (30, 10 mg pellets) than an equicaloric, single piece of food (300 mg) showing that multiple pieces of food are more rewarding than a single piece. Chapter 2 Experiment 2 showed that rats preferred a 30-pellet food portion clustered together rather than scattered. Preference and motivation for clustered food pieces may be interpreted based on the optimal foraging theory that animals prefer foods that can maximize energy gain and minimize the risk of predation. Chapter 3 Experiment 1 showed that college students preferred and ate less of a multiple-piece than a single-piece portion and also ate less in a test meal following the multiple-piece than single-piece portion. Chapter 3 Experiment 2 replicated the results in Experiment 1 and used a bagel instead of chicken. Chapter 4 showed that college students given a five-piece chicken portion scattered on a plate ate less in a meal and in a subsequent test meal than those given the same portion clustered together. This is consistent with the hypothesis that multiple pieces of food may appear like more food because they take up a larger surface area than a single-piece portion. All together, these studies show that number and surface area occupied by food pieces are important visual cues determining food choice in animals and both food choice and intake in humans.

The unpleasant bitter taste found in many nutritious vegetables may deter people from consuming a healthy diet. We investigated individual differences in taste perception and whether these differences influence the effectiveness of bitterness masking. To test whether phenylthiocarbamide (PTC) `supertasters' also taste salt and sugar with greater intensity, as suggested by Bartoshuk and colleagues (2004), we infused strips of paper with salt water or sugar water. The bitterness rating of the PTC strip had a significant positive linear relationship with ratings of both the intensity of sweet and salt, but the effect sizes were very low, suggesting that the PTC strip does not give a complete picture of tasting ability. Next we investigated whether various seasonings could mask the bitter taste of vegetables and whether this varied with tasting ability. We found that sugar decreased bitterness and lemon decreased liking for vegetables of varying degrees of bitterness. The results did not differ by ability to taste any of the flavors. Therefore, even though there are remarkable individual differences in taste perception, sugar can be used to improve the initial palatability of vegetables and increase their acceptance and consumption.

Statistics are rising for adults who are overweight and/or obese, putting them at higher risk of developing serious health problems. Eating fewer portions of vegetable than the daily-recommended amounts contributes to this increase with. College students, being more susceptible to weight gain as they are transitioning from childhood to adulthood. Previous studies demonstrated that children ate more vegetables when repeatedly paired with a low-fat dip compared to when served plain. The current study examined whether this effect was also successful in college-aged subjects. A total of 148 (55 males, 91 females) college-aged students from an introductory psychology class at Arizona State University (Tempe, AZ) participated in the study. Subjects were randomly assigned to receive cauliflower or broccoli (raw) either served plain or with low-fat ranch dressing. Subjects showed a greater preference for and consumption of the vegetable plain that was previously given with dip than without dip. These findings suggest that serving vegetables with low-fat ranch dip two times can increase the liking and consumption of vegetables in college students.

I spent the first half of my project researching Mexican cuisine, as well as the history of traditional recipes and how various ingredients became incorporated into the food of the Southwest region. The second half of my project was focused on creating a video to document my family's recipe for making tamales. I analyzed the recipe and its larger cultural and social implications which I presented with a PowerPoint.

Most reliable nutrition information can be found online, but it can be nearly impossible to differentiate from the unreliable blogs and websites that claim their information is correct. Because of this, it can be difficult for students to determine which information is true and which advice they will follow. During this time of growth and learning, it is essential that students have access to accurate information that will help them to be healthier individuals for years to come. The goal of this project was to provide students with an easily accessible and reliable resource for nutrition information that was presented in a simple and relatable way. The following videos and attached materials were created in response to ASU student needs and will be available for students on the ASU wellness website.

Description
Introduction: A mini-documentary consisting of 4 student interviews and 1 professional interview was created for the purpose of providing examples of how body image and eating behaviors affect overall wellness and starting more conversation of this topic. Literature Review: A review of some of the current literature involving body image and wellness interventions suggests that body image is a significant factor of health and wellbeing. Wellness interventions, mostly "non-diet" approaches, that omit weight loss as a primary goal could be a suitable solution for some people wanting to make sustainable healthy lifestyle changes. The social media site, YouTube, was chosen to share the documentary based on the ability of social media to reach more people, engage them, and spread messages and information quickly. Methods: Participants of the video were volunteers responding to an ad posted on the Barrett, the Honors College daily newsletter. Michelle May, M.D. was interviewed to provide a professional perspective on the subject. Questions asked of the student participants were meant to provide examples of how each of their relationships with their bodies and food affected their ideas of health and vice versa. Final Video: The final video, titled "Food & You" can be found on YouTube: https://youtu.be/ShmAzlx2GhM Discussion and Conclusion: Overall, weight and body size still seem to play a role in the ideas the students interviewed have of health. As more research into improving body image is done, knowing how to add this to personal and health professional practice should be encouraged. Moving away from the weight-focused idea of health could improve body image and overall wellness.
