While saffron may be the world’s most expensive spice, fortunately a little goes a long way. It’s used sparingly to add golden-yellow color and a slightly floral flavor to a wide variety of Middle Eastern, African and European-inspired foods. And research suggests the spice can boost your mood, by having antidepressant effects and helping to alleviate PMS symptoms. Researchers believe that the spice works by “the same mechanism as Prozac,” helping to make the feel-good neurotransmitter serotonin more available to the brain.
