Is it ok to drink milk tea daily?

No. Too much sugar.: The human body is not meant to eat sugar except in occasional small quantities. Sugar does bad things to the body. It is best to order the tea with no added sugar. Then calories would come from the flavoring (has some sugar), the extras like boba pearls, and the "milk" which is either a type of non-dairy creamer or is real milk. Healthy people might have one drink a week, with no added sugar.
