A higher adherence to a healthy or Japanese dietary pattern may associated with reduced symptoms of depression during pregnancy

In January 2018 researchers from Japan published the results of their study to assess the association between dietary patterns and depressive symptoms during pregnancy. A total of 1,744 pregnant women were involved in the study. Information on dietary patterns was collected via a diet history questionnaire. The level of depression was assessed in all individuals. Three dietary patterns were identified: ‘healthy’, characterized by a high intake of green and yellow vegetables, other vegetables, mushrooms, pulses, seaweed, potatoes, fish, miso soup, and shellfish; ‘Japanese’, characterized by a high intake of rice and miso soup; and ‘Western’, characterized by high intake of beef and pork, processed meat, vegetable oil, chicken, eggs, shellfish, and salt-containing seasonings. Results showed that a higher adherence to both the healthy and Japanese patterns were independently associated with a reduced incidence of depressive symptoms during pregnancy. No association was observed between the Western dietary pattern and depressive symptoms during pregnancy.
