Matcha

Matcha tea is kind of like a super-powered green tea: since you're ingesting the whole leaf instead of just the brewed beverage, you get up to ten times the antioxidant effect and nutritional value of your standard green. Matcha is rich in antioxidants, as well as chlorophyll and fiber, and has been found to have natural mood enhancing effects. All in all, matcha's got no match when it comes to healthy teas.
