Preparation plays an important role
The researchers emphasize that the way tea is prepared can influence its health benefits.
Bottled tea is processed at high temperatures
During the production of bottled tea, high temperatures are often used for sterilization. This can reduce the amount of certain antioxidants.
Bubble tea contains many additives
Bubble tea often consists of tea combined with tapioca pearls, milk, flavorings, and preservatives.
Additives can increase calorie intake
The ingredients in bubble tea can add around 150 to 200 extra calories per serving.

Sugar may affect health
A high intake of added sugar can raise blood sugar levels and increase the risk of diseases such as type 2 diabetes and cardiovascular disease.
Tea still contains active compounds
Even in bubble tea, antioxidants from the tea itself are still present and may have positive effects.
Occasional consumption recommended
Experts recommend that bottled tea and bubble tea should be enjoyed occasionally rather than as a daily habit.
Freshly brewed tea provides the most benefits
According to the research, freshly brewed tea generally provides more health benefits than ready-made varieties.
