Tea

Not a coffee person? Tea has a pretty impressive résumé of health benefits, too. Because it has less caffeine, it hydrates you more effectively than coffee, and it's also a rich source of the immunity-boosting antioxidants known as catechins.

All tea (black, green, or white) provides antioxidants, but green tea may be healthiest of all. Research suggests that drinking five cups a day can increase your body's metabolism and help you lose more weight around the middle.
