Soda and processed fruit juices double your risk of getting cancer in the gallbladder, according to a 13-year study.

Compared with people who avoided the drinks altogether, people who consumed at least sugar-sweetened drink a day had more than twice the risk of developing gallbladder tumors, according to experts at the Karolinska Institute in Sweden.

Drinking sugar-sweetened drinks also had a 79 per cent higher risk of getting biliary tract cancer – bile ducts in the liver – than their healthier counterparts, the study found.

The researchers analysed survey data on the eating and drinking habits of more than 70,000 adults then followed them for more than 13 years on average to see whether cancers got diagnosed.

At the start of the study, participants completed food and drink questionnaires that asked how many sodas or juice drinks they had consumed in the past week and how much they typically consumed during the previous year.

When they answered these questions in 1997, participants were 61 years old on average. About half of them were overweight and roughly 25 percent were current smokers.

The increased risk of gallbladder and biliary tract tumors persisted even after researchers adjusted for whether participants were overweight.

Researchers excluded people with a previous cancer diagnosis or a history of diabetes.

Healthy lifestyle is the key to cancer-free life

Dr Margo Denke, a former researcher at the University of Texas Southwestern Medical School in Dallas who wasn’t involved in the study said: “this study suggests that there is more than a plausible link; the incidence of biliary and gall bladder cancer was higher among individuals who consumed more sodas and juices”

Dr. Igor Astsaturov, a medical oncologist at Fox Chase Cancer Center in Philadelphia who wasn’t involved in the study said: “Obviously, this finding signals again and again that healthy lifestyle is the key to cancer-free life”.
