6 Healthy Types of Tea

Oolong Tea

The scoop: Oolong is similar to black tea, but it’s fermented for a shorter time, which gives it a richer taste. It contains about 30 milligrams of caffeine per cup.

Health benefits: It may aid in weight loss. “Oolong activates an enzyme responsible for dissolving triglycerides, the form of dietary fat that’s stored in fat cells,” says Baer. One study showed that women who drank oolong tea burned slightly more calories over a two-hour period than those who drank only water.
