  • Dietary Guidelines

Purpose:

The purpose of this research is to better understand people's health and diet knowledge, beliefs, attitudes, and practices. The researchers will use this information to implement better strategies to help Americans maintain more nutritious diets.


Study summary:

The overall goal of this study is to determine whether there are differences in perceptions of healthy nutrition messages depending on from whom the message is coming. More specifically, the researchers aim to examine whether there are differences in how people perceive and intend to follow nutrition information that is coming from an unspecified source (control), a social media source (health page), a medical source (hospital), and a government agency (USDA). The unspecified source will serve as a control, as it is the most neutral option (i.e., any other logo would serve as a potential prime for participants' attitudes and beliefs). In addition to the manipulation, the researchers will examine whether any personal characteristics, such as gender and race, predict trust and perceptions.
