Does drinking tea really help health?

Scientists can’t say for sure yet if tea is good for health. However, the overall evidence on tea consumption indicates a potential benefit. Drinking tea is linked to reduced risks for heart disease, high blood pressure, stroke, diabetes, dementia, stress, and early death. The health benefits of tea come with drinking two to four daily cups of green, black, or oolong tea. Other types of tea, such as the fermented tea known as pu-erh, might also be good for health, though the supporting evidence is more limited.
