Impact of Dietary Interventions on Anxiety, Depression and Stress-A Narrative Review

Recently multiple studies focused on the role of nutrition in mental health. The present narrative review aimed to assess the impact of dietary interventions on depression, anxiety and stress. Articles were searched in three journal databases and selected using standard protocol to select 12 articles for the current review. A narrative review was prepared based on the data available from the selected articles. The findings indicated that dietary interventions (i.e. supplementation of fish oils and multiple micronutrients, and dietary intake of plant-based foods) had beneficial effects and reduced depression, anxiety and stress. The studies were primarily from developed countries and further studies from developing countries are needed.
