A systematic review of the association between dietary patterns and health-related quality of life.

According to the current evidence, "Healthy" dietary patterns and "Mediterranean" dietary patterns are associated with better dimension scores of HRQOL in both physical and mental summaries. While, unhealthy dietary patterns and "Western" dietary patterns are associated with lower scores of HRQOL. Further longitudinal studies are required to clarify the association between dietary patterns and HRQOL.
