2. Lean protein foods
Lean protein may play an important role in regulating mood, Dr. Cerrone says. While more research is needed into the role protein plays in managing depression, one research review notes that studies have found that peptides (short chains of amino acids that are part of larger protein molecules) found in soy, rice, and dairy products may have antidepressant effects.
Low-fat cheese and milk, eggs, chicken, turkey, fish, lean beef, low-fat Greek yogurt, and beans are all good sources of lean protein, Cerrone says.
Vitamin B12 is also involved in the production of brain chemicals that affect mood, and a deficiency of this important nutrient may be associated with depression.
