Study finds those who drink artificially-sweetened beverages such as Diet Coke or Pepsi Max are at three times the risk of suffering strokes compared to non-drinkers.
JUST one diet drink a day can triple the risk of a deadly stroke, a study suggests.
The researchers also found links to dementia described as a “worrying association” by experts.
But the findings were dismissed by some British authorities, while others have called for more investigation.
The US study found those who drank a can of artificially-sweetened pop — such as Diet Coke or Pepsi Max — daily were at three times the risk of suffering the most common form of stroke compared to non-drinkers.
They were also 2.9 times more likely to develop Alzheimer’s. But after accounting for all lifestyle factors, the researchers found the link to dementia was statistically insignificant.
However, the impact on stroke risk remained.
The team from Boston University School of Medicine looked at ten years’ worth of data from more than 4,300 people.
Its Dr Matthew Pase urged people to drink water instead — a stance supported by the National Obesity Forum in the UK.
Its spokesman Tam Fry said: “Don’t be fooled by the use of the word ‘diet’.”
