Fizzy drink link to prostate cancer?

Comment on this story
cold drink . The University of Liverpool academic said a third of Britains children, and two-thirds of adults, are now overweight or obese  but halving childrens intake of sugar-sweetened drinks could arrest or even reverse current trends.

London - One sugary soft drink a day could raise a man’s odds of developing prostate cancer.

A 15-year study found those who drank 300ml of a fizzy drink a day – slightly less than a standard can – were around 40 percent more likely to develop the disease than those who never consumed the drinks.

Worryingly, the risk applied not to early-stage disease that was spotted via blood tests but to cancers that had progressed enough to cause symptoms. This is significant as faster-growing forms of prostate cancer are more likely to be deadly.

It is thought that sugar triggers the release of the hormone insulin, which feeds tumours.

Prostate cancer is the most common type in British men, affecting almost 41,000 a year and killing more than 10,000.

The study, published in the respected American Journal of Clinical Nutrition, is far from the first to link the sugary soft drinks enjoyed by millions of Britons every day to poor health. Previous research has flagged up heart attacks, diabetes, weight gain, brittle bones, pancreatic cancer, muscle weakness and paralysis as potential risks.

The Swedish scientists behind the latest work said that while more research is needed before the link with prostate cancer can be confirmed, there are already “plenty of reasons” to cut back on soft drinks.

For the study, they tracked the health of more than 8,000 men aged 45 to 73 for an average of 15 years. The men, who were in good health at the start of the study, were also quizzed about what they liked to eat and drink.

At the end of the study, they compared the dietary habits of the men who had been diagnosed with prostate cancer with those who remained healthy and found a clear link between sugary drinks and the disease.

Lund University researcher Isabel Drake said: “Among the men who drank a lot of soft drinks we saw an increased risk of prostate cancer of around 40 percent.”

The analysis also linked large amounts of rice and pasta, cakes and biscuits and sugary breakfast cereals with a less serious form of the disease.

There was no link with fruit juice. Diet drinks and tea and coffee with sugar were not included in the study.

The researchers said that although genetics play a bigger role in prostate cancer than in many other tumours, diet also appears to be important. However, Mrs Drake, a PhD student, added that more research is needed to prove the link.

British experts also urged caution over the findings. Dr Iain Frame, director of research at Prostate Cancer UK, said: “We cannot be certain whether any particular dietary pattern has a significant impact on a man’s risk of getting prostate cancer but it is highly unlikely that any single food source will lead to an increased chance of developing the disease.” - Daily Mail
