UK soft drink tax: Doctors urge a 20 percent tax on fizzy drinks

A new study found that, compared to normal weight women, obese women were 40 percent more likely to have a breast cancer recurrence over the study period and 69 percent more likely to die from breast cancer. The study also showed that women who were simply overweight were also at risk of higher cancer reoccurrence.

UK's doctors have called for a 20 percent tax on soft drinks and have asked for junk food advertisements to be banned.

The Academy of Medical Royal Colleges, which represents almost every one of the the UK's 220,000 doctors, have also asked for fewer fast food outlets near schools and have asked for a ban on unhealthy snack in hospitals as a countermeasure to the country's rising obesity rates.

According to the academy, obesity is the greatest public health crisis facing the UK. One in four adults is obese, and these figures are only expected to rise. According to the academy, by 2050 60 percent of men, 50 percent of women and 25 percent of children will be obese.

"The consequences of obesity include diabetes, heart disease and cancer and people are dying needlessly from avoidable diseases," wrote the academy, the Guardian reported.

Professor Terence Stephenson, chairman of the academy, said that the report was not a full solution to obesity, and that there is no "silver bullet" to tackling widespread obesity, the BBC reported.

However, the Food and Drink Federation, which represents industry leaders and manufactures, said that the academy's report didn't add much to the current debate, pointing out that the report didn't recognize the role alcohol played in obesity, and that it made no mention of increasing exercise.
