STARBUCKS’ iced teas contain more added sugar than the recommended daily limit for adults.
A large-sized blood orange tea has 45g — 11 teaspoons — the same as 3½ glazed Krispy Kreme doughnuts.
The NHS suggests adults keep their sugar intake below 30g a day, which is seven teaspoons.
Starbucks’ strawberry & lime tea and the tropical mango version also exceed 30g when going large.
Paul Evans, of the British Obesity Society, said: “This latest range shows Starbucks isn’t taking the battle against obesity seriously.
Packing up to 11 teaspoons of sugar in a single cup of tea is guaranteed to lead to health complications such as strokes, heart disease and diabetes.”
The British Dental Association’s Mick Armstrong said sugary drinks also fuel tooth decay.
Spokesman Mick Armstrong said: “Britain must wean itself off its sugar addiction but coffee chains are banking on us upping the dose.”
Starbucks was contacted for comment.
