In the New Scientist, Shaoni Bhattacharya has news of a link between cancer of the esophagus and soft drinks from the Digestive Disease Week conference in New Orleans:
Mohandas Mallath, head of the digestive diseases department at Tata Memorial Hospital, India, and colleagues found a "very significant correlation" between the rise in consumption and esophageal cancer globally. The effects took about 20 years to come through, they believe.
The trend was seen in other countries where fizzy drinks have risen in popularity, such as the UK and Australia. But in countries where soft drinks have not caught on like Japan or China, there has been no increase in the cancers affecting the esophagus, the tube linking the mouth and stomach.
