Best Antidepressant Diet

A recent study has found that changing your diet could significantly improve your mood. The link between food and mood is part of an emerging field of psychiatry called “nutritional psychiatry.” There is growing scientific evidence that, what we eat significantly impacts our emotions and well-being.


A randomized controlled study of 67 participants examined the impact of dietary changes on depression. Researchers provided seven individual nutritional counseling sessions over a 12-week period, encouraging changes in diet through techniques including motivational interviewing, goal setting, and mindful eating. The group that made changes to their diet had a significantly greater improvement in their depression.



The dietary guidelines recommended 12 key food groups (serving sizes listed):

  • Whole grains (5-8 servings per day)

  • Vegetables (6 servings per day)

  • Fruit (3 servings per day)

  • Legumes (3-4 servings per week)

  • Low-fat, unsweetened dairy (2-3 servings per day)

  • Raw and unsalted nuts (1 servings per day)

  • Fish (at least 2 servings per week)

  • Lean read meats (3-4 per week)

  • Chicken (2-3 per week)

  • Eggs (up to 6 per week)

  • Olive Oil (3 tbl per day)

Participants in the diet were told to avoid or reduce these:

  • Sweet refined cereals

  • Fried food

  • Fast-food

  • Processed Meats

  • Sugary drinks, soda (no more than 3 per week)

  • Alcohol/wine

The exact mechanism for how a healthier diet can improve mood and continues to be the focus of current research. One hypothesis is that foods high in sugar and saturated fats are linked to higher levels of chronic inflammation. The study focused on people who did not eat healthily to begin with, so changes in mood may not be as significant for those who already eat fairly healthily. Regardless, making healthy nutritional changes can be a useful tool to improve your mood as well as your physical health.
