Current evidence points to the many potential benefits of tea drinking—some of which appear to be associated with its antioxidative properties, whereas others may simply coincide with a healthy lifestyle. Nevertheless, the uneven quality of the data and the diverse types of studies make it difficult to draw firm conclusions. Which teas have the strongest health benefits (or risks) and why remains unknown. Researchers still need to address many facets surrounding tea and health, including the ideal brewing methods; the addition of substances; the frequency, amount, and duration of consumption; and whether a tea leaf’s health potential declines as it ages. Furthermore, a significant proportion of studies were conducted in Asian populations, where tea drinking is widespread. Future research should include more diverse populations of tea drinkers.
