Frappuccinos do contain coffee and could be considered an espresso drink.
But most Frappuccinos do not use espresso machines to make them but instead the Frappuccinos that most places including Starbucks serves is made using a powder mix that hot water goes over in a Frappuccino machine.
So because of that the Frappuccinos are not counted as espresso drinks.
Frappuccinos are good for you in moderation because they do contain milk which is a good health drink that helps build strong bones.
However too many Frappuccinos can be bad for you.
Other than the milk and the coffee that Frappuccinos are made from the Frappuccinos themselves do not provide any health benefits.
But the coffee does help improve heart health when drank in moderation and Frappuccinos do contain some coffee.
But Frappuccinos also contain fat, sugar and lots of calories so if you drink too many Frappuccinos then you may gain weight as a result of the Frappuccinos and your health may decline.
Having one Frappuccino or two Frappuccinos per day everyday is not gonna harm you as long as you're drinking other healthy drinks.
