6. Tea may keep your smile bright
"Japanese researchers have found that tea can decrease tooth loss," Ardine says. "It changes the pH in your mouth when you drink it and that may be what prevents cavities." Beyond that, tea, unlike many other beverages does not appear to erode tooth enamel, Bonci says.
7. Tea may boost the immune system
Studies have shown tea can tune up immune cells so they reach their targets quicker.
8. Tea may help battle cancer
Studies on this are currently mixed, which means more research is needed, Bonci says. But, in the meantime, "if you've got a strong family history of cancer and you want to do anything you can, you might increase your tea consumption," she adds.
9. Herbal tea may soothe the digestive system
"Herbal teas, in particular chamomile, can be good for people with irritable bowel syndrome because it is an antispasmodic," Bonci says. "And ginger teas can calm nausea."
10. Tea — unadulterated, that is — is calorie free
"It's a great no-calorie alternative to water," Bonci says. "It provides so many options for flavor and versatility. You can have it hot or cold. And you don't have to put anything in it, though you might want to add a cinnamon stick or some ginger. That means you're able to hydrate with something other than water alone."
