Pharmacological Research: The official Journal of the Italian Pharmacological Society, 2010 Mar;61(3):234-41 .The body does not naturally produce Omega-3s, so the fatty acid needs to be consumed from outside sources. Deficiency symptoms include fatigue, mood swings, memory decline, and depression.
How eating it helps: Studies show a correlation between consumption of fish with high levels of Omega-3 fatty acids and a decreased risk of depression and suicide Serum omega-3 fatty acids are associated with variation in mood, personality and behavior in hypercholesterolemic community volunteers. Conklin, S.M., Harris, J.I., Manuck, S.B., et all. Cardiovascular Behavioral Medicine Postdoctoral Training Program, Department of Psychiatry, University of Pittsburgh, Pittsburgh, PA.

RDA: There is no established RDA for Omega-3s, but the American Heart Association suggests eating a variety of fish (trout, herring, and salmon) at least twice a week. For vegetarians, there are also plenty of non-meat sources of Omega-3s (see below for a few suggestions). That said, the fatty acids found in plant sources are different from those found in marine sources, and it may be smart for vegetarians to consider using supplements that contain DHA Omega-3s (algae supplements are a popular way to do so) in order to derive maximum benefits.

Coppen, A., Bolander-Gouaille, C. MRC Neuropsychiatric Research Laboratory, Surrey, UK. Journal of Psychopharmacology, 2005 Jan; 19(1):59-65 . Vitamin B-12 is found naturally in meats, eggs, and animal byproducts, meaning vegetarians and vegans have an increased risk of developing a deficiency.
How eating it helps: Because moods depend largely on signals from the brain, B12 plays an important role in regulating depression — consuming enough vitamin B12 allows the body to synthesize a group of nutrients critical for normal neurological function Methylmalonic acid and cognitive function in the Medical Research Council Cognitive Function and Ageing Study.

Black, L.J., Jacoby, P., Allen, K.L., et all Telethon Institute for Child Health Research, Centre for Child Health Research, The University of Western Australia, Australia. Australia and New Zealand Journal of Psychiatry, 2013 Nov 13 . Most often, lowered levels of Vitamin D are the result of indoor lifestyles, limited sun exposure, and inadequate intake of vitamin-D-rich foods.
How eating it helps: If you’re feeling blue, increasing vitamin D could help ward off depression. Consuming the mood-regulating vitamin is important, especially during the wintertime when light from the sun (a natural producer of vitamin D) is limited Vitamin D and depression: where is all the sunshine?

Low levels of zinc in the diet can lead to a variety of ailments, including a weakened immune system, loss of appetite, anemia, hair loss, and depression. Vegetarians need as much as 50 percent more zinc than non-vegetarians due to the body’s lower absorption rate of plant-based zinc Complementary and Alternative Medicine (CAM) Therapies to Promote Healthy Moods. Kemper, K., Shannon, S. Pediatric Clinics of North America, 2007 December; 54(6): 901–926 .
