Association of recommended food score with depression, anxiety, and quality of life in Korean adults: the 2014–2015 National Fitness Award Project

Background A healthy diet is a key determinant of an individual’s health status and is closely related to mental health and quality of life (QoL); however, the exact nature of the relationship is unknown. This study hypothesized that a higher diet quality score is associated with a lower observance of symptoms of depression and anxiety and a higher QoL.
