Green vegetables
Whenever you feel down, eat your greens! Besides preventing different types of cancers, boosting heart health, and offering a youthful appearance, green veggies can also combat depression. Veggies are packed with folate (vitamin B-9), and since it appears that depression is linked to low levels of this B vitamin, you should definitely eat your veggies.
Studies point out that people with high folate levels tend to be happier than those who have low levels of this B vitamin. Researchers don’t know exactly what’s the connection between the two, but they believe that a folate deficiency shrinks the production of dopamine, noradrenaline, and serotonin.
Nonetheless, it’s a good idea to eat plenty of green vegetables like spinach, asparagus, edamame, peas, cucumbers, kale, and broccoli.
