“We’re going to ask Dunkin’ Donuts and Starbucks, ‘Show us the safety data that show that it’s OK for a teenage girl to drink an iced coffee with 115 grams of sugar in it,’” Kennedy said. “I don’t think they’re gonna be able to do it.”
Flavored iced coffees at Dunkin’ can have between
18 and 67 grams of sugar, while the chain’s frozen beverages can range from 100 to 180 grams.
Meanwhile, adding a flavored syrup to a Starbucks iced coffee adds approximately 20 grams of sugar to the drink. The chain’s frozen offering, known as the frappuccino, can have between approximately 40 and 80 grams of sugar.
