Bubbletea would be fattening, that is when you eat a lot of pearls.
Real fruit smoothies, gelato or organic matcha would do no harm to adult.
Ironically it is not for aging people like me, but how can parents forbid
their kids from eating/drinking unhealthy stuffs?
I know so many college teens which do not drink, not gamble, no cigarette,
just smoke joints, sometimes with their professors, especially art institutes.
