The relationship between dietary quality, serum brain-derived neurotrophic factor (BDNF) level, and the Val66met polymorphism in predicting depression

Background: Brain-derived neurotrophic factor (BDNF), a neurotrophic factor implicated in the pathogenesis of depression, may be influenced by dietary quality. Both dietary quality and serum BDNF have been researched independently in regard to their effect on depression; however, there is limited research investigating the relationship between the two factors and how they interact in depression. Additionally, a single-nucleotide polymorphism...
