Diet fizzy drinks make you 60% MORE likely to get diabetes than regular, 'full fat' versions

Drinking one can a week of any type of fizzy drink increases risk of diabetes by a third

Women who drank 1.5 litres of diet drinks a week had up to 60 per cent increased risk of the disease

Artificial sweeteners in diet drinks may be to blame

Diet fizzy drinks can raise the risk of diabetes by 60 per cent, startling new research has revealed.

A study of more than 66,000 women found those who drank artificially sweetened drinks were more likely to develop the disease than those who indulged in regular, 'full fat' versions.

The findings, published in the American Journal of Clinical Nutrition, fly in the face of conventional thinking that regular versions of fizzy drinks are always worse for our health.



The effect is compounded by the fact that diet drinkers also consume more - on average 2.8 glasses a week compared to 1.6 for regular drinkers.

Regular, full-fat versions of fizzy drinks have previously been linked to an increased risk of diabetes.

But less is known about their artificially sweetened counterparts - often promoted as a healthier substitute.

In the study, more than 66,000 middle-aged French women were quizzed about their dietary habits. Their health was then monitored over 14 years from 1993 to 2007.

The researchers, from the National Institute of Health and Medical Research in France, examined the rates of diabetes among women who drank either regular or diet fizzy drinks and those who drank only unsweetened fruit juice.



Women who drank fizzy drinks had a higher risk of diabetes than those who only consumed juice.

Those who drank up to 359ml of any type of fizzy a week - just more than a regular-sized can - were a third more likely to develop the disease. The risk was more than double in those who drank 600ml a week - just bigger than a regular bottle.



Drinkers of diet drinks had an even higher risk of diabetes compared to those who drank regular ones.



Those who drank up to 500ml a week had a 15 per cent increased risk. Once more than 1.5 litres a week was consumed, this became a 60 per cent increased risk.

'Contrary to conventional thinking, the risk of diabetes is higher with "light" beverages compared with "regular" sweetened drinks,' the researchers said.

The paper noted previous research which had showed that aspartame - the most wisely used artificial sweetener - has a similar effect on blood glucose and insulin levels as the sucrose used in regular sweeteners.

World Health Organisation statistics show that 347 million people worldwide have diabetes, a chronic disease which occurs when the pancreas does not produce enough glucose-controlling insulin, or when the body cannot efficiently use it.
