The association of overall dietary quality on stress, anxiety, depression, and academic performance in college students: a systematic review.

The objective of this systematic review was to examine current evidence regarding the associations between dietary quality and mental well-being indicators (stress, anxiety, and/or depression) in college students, with a secondary aim of characterizing the relationship between overall dietary quality and academic performance. : Searches were performed, and the PRISMA guidelines were followed for reporting the methods and results. Twelve observational studies were included and reviewed showing high dietary quality was associated with: low stress (four studies), stress (one study), and no significant association (two studies); low depression (three studies) and no significant association (two studies) and low anxiety (two studies), anxiety (one study), and no significant associations (two studies).

Opportunities for Maximizing the Dietary Quality of Fad Diets.

The quality of American diets, measured by the Healthy Eating Index (HEI), has remained stable and low since 2005.

Holistic Framework to Contextualize Dietary Quality Assessment: A Critical Review.

Numerous dietary quality indices exist to help quantify overall dietary intake and behaviors associated with positive health outcomes. Most indices focus solely on biomedical factors and nutrient or food intake, and exclude the influence of important social and environmental factors associated with dietary intake. Using the Diet Quality Index- International as one sample index to illustrate our proposed holistic conceptual framework, this critical review seeks to elucidate potential adaptations to dietary quality assessment by considering-in parallel-biomedical, environmental, and social factors.
