You Won't Believe How Much Sugar Is In Your Starbucks Drink

Maybe that caffeine buzz is actually just a sugar high.

Your Starbucks white chocolate mocha with whipped cream could have as much as 18 teaspoons of sugar, according to a new report from the British campaign group Action on Sugar. That's nearly twice as much sugar as a can of Coke.

The group tested sugar levels in hot drinks from nine coffee shops and food chains in the U.K., including shops like Starbucks and McDonald's.

The worst offenders were the hot mulled fruit drinks sold at British Starbucks, which clocked in at a whopping 25 teaspoons of sugar for a venti. So, if you're planning a trip there, consider steering clear of the fruity concoctions. According to the World Health Organization, adults should be consuming about 6 teaspoons of sugar a day. 

Other drinks that far surpassed that daily recommendation include Starbucks' chai tea latte, which has 13 teaspoons of sugar in a venti, and the Starbucks signature hot chocolate, clocking in at 12 teaspoons of sugar for a grande. 

The most sugary sip McDonald's offers is a large mocha, with 11 teaspoons of sugar.

A Starbucks spokesperson tells MarieClaire.com the company has plans to reduce the sugar in its "indulgent drinks" by 25 percent by the end of 2020, adding: "We also offer a wide variety of lighter options, sugar-free syrups and sugar-free natural sweetener and we display all nutritional information in-store and online."

Bye-bye, sweet mochas!
