FAQ

Library Membership FAQ

A: Studies are chosen that illuminate the connection between the psychological sciences and nutritional sciences and help us to understand the connections between nutrition and all aspects of mental health.

A: Not always, but frequently. The database provides links to original research abstracts. Full PDFs of each study can frequently be found in the link provided, or with a bit of additional searching, however, the central purpose of the Library Membership is to provide you with quick, convenient access to a carefully curated library of nutritional psychology research.

A: Yes. The CNP team identifies daily studies published in areas relevant to nutritional psychology. New studies and their CNP-written summaries are added daily.

A: CNP summaries are summaries of study abstracts written by CNP staff in an effort to increase readability for CNP learners and to increase the speed with which they can cover relevant research in the field. In this way, CNP aims to make research accessible for everyone.

A: The five research libraries that CNP Members gain access to are one of a kind; they specifically bring nutritional psychology research publications all to one place and make them easy to search, organize, and use. CNP staff have collectively spent thousands of hours hand-identifying and selecting studies for inclusion in the CNP research libraries, organizing them by category, and writing CNP summaries for ease of understanding. This is a valuable tool for using NP-related research in papers and projects, viewing scientific trends, and utilizing collective knowledge on NP.
