The goal of this study was to investigate visual sources of nutrition information relied upon by young adults, specifically college-aged students between 18-30, as this is an under-represented population within current academic literature. A sample of more than 700 18- to 30-year-old college students were surveyed regarding their use of nutrition-driven information, with specific questions regarding the participants' awareness and use of the Food and Drug Administration's standardized nutrition facts labels, as well as the use of smartphone applications for tracking one's food and beverage consumption on a regular basis. Using structural equation modeling, a statistically significant theoretical model was developed with regards to individuals finding greater long-term satisfaction in their dieting efforts if they tracked their consumption on a regular basis, with even greater significance being found through the aid of smartphone applications for recording consumption. An analysis of the content of three online diet and exercise-driven brands was also conducted to determine the currently optimal social media platform for nutrition information exchange, and to identify the type of diet-driven information that generates the greatest amount of engagement within an online network. Of the social media platforms analyzed, Instagram proved to be the most optimal for nutrition information-exchange, and that humorous and relevant content shared by dieting brands generated the greatest engagement within their online networks. These studies confirmed that formal visual sources of information, specifically the FDA's nutrition fact labels, are not regularly acknowledged nor implemented within this population, but rather informal visual sources of information, such as content shared across social media channels and the use of smartphone applications, are heavily relied upon when dieting within the young adult population. These research implications are relevant and timely to academics, health professionals, and governmental entities, as they support the need for greater educational endeavors towards increasing the public's nutrition and food literacies, as well as provide an improved strategy for individuals who are dieting through a model for increased satisfaction in one's dieting efforts.
