Sugary drinks cancer-causing
The consumption of sugary drinks has exploded worldwide in recent decades and the high-calorie beverages have already been associated with an elevated risk of obesity—itself recognized as a leading cancer risk factor. A team of researchers in France wanted to assess the associations between heightened consumption of sugary drinks and the risks of overall cancer, as well as several cancer types, including breast, prostate and bowel cancers. They surveyed more than 100,000 adults, with an average of age of 42, 79 percent of whom were women. The participants, who were followed for a maximum of nine years, completed at least two 24-hour online validated dietary questionnaires, calculating their daily consumption of sugar and artificially sweetened beverages as well as 100 percent fruit juices. Researchers measured the daily intakes of sugary drinks against those of diet beverages and compared them to cancer cases in participants’ medical records during the follow-up period. They found that just a 100 ml increase per day of sugary drinks was associated with an 18 percent increased risk of cancer, and with a 22 percent increase in breast cancer. Both sugar-sweetened drinks and fruit juices saw a similar higher risk association.
