Vitamin D helps regulate cell growth, plays an important role in maintaining the immune system and (when paired with calcium) protects bones. Studies show that low levels of Vitamin D are associated with depressive symptoms in both men and women. 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.

Zinc is found in almost every cell and plays an important role in supporting a healthy immune system and helping the body protect the gut from damage. 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.
How eating it helps: Studies have identified zinc as an important factor in decreasing depressive symptoms, as the vitamin can improve the response of antidepressants while reducing the side effects of antidepressant medication. A lack of zinc can trigger depressive behaviors, so load up on zinc-rich foods to balance your mood.
