The tapioca pearls or the boba balls need to be chewed before swallowing. Swallowing the tapioca pearls can be hazardous. Even on absorbing the maximum amount of moisture, the tapioca pearls do not dissolve by themselves. They are difficult to digest as such. So always make sure that you chew them before swallowing. Nothing is bad in moderation. But excess of everything is bad. If you drink too much boba, almost every day, it may cause some long-term health hazards. Let us be honest bubble tea is sugar and carb-rich food. Drinking boba regularly does not fall in the scheme of a healthy balanced diet. But It is not gonna clog your intestine at all. But consuming too many sugars can make you dehydrated. High sugar bubble tea could be in some way contributing to that.
