| Outline of Final Research Achievements |
This study was aimed to examine the association of dietary and nutritional factors and dietary patterns with serum brain-derived neurotrophic factor (BDNF) among 2162 men and women who participated in a health survey. Participants were asked to fill out two types of survey questionnaire (for diet and for overall health-related lifestyle) and to donate venous blood.
Serum concentrations of folate and 25-hydroxyvitamin D and dietary intakes of docosahexaenoic acid and eicosapentaenoic acid were not associated with serum BDNF concentrations. For dietary pattern analysis, a healthy dietary pattern characterized by high intakes of vegetables, fruits, mushrooms, potatoes, seaweeds, soy products was associated with lower concentrations of BDNF.
