Daily glass of fruit juice or diet soda can boost disease risk, new French study of 100,000 adults shows

Even one daily glass of juice or soda can increase your risk of cancer. 

That conclusion, according to a recent story by Najja Parker in The Atlanta Journal-Constitution, stems from a new study of 100,000 French adults who were followed for nine years.

The study, published in the British Medical Journal, says that consuming sugary drinks each day — in amounts as small as 100 ml of 100% fruit juice or one-third of a typical can of an artificially sweetened diet beverage — is now “associated with an overall increase in cancer risk of 18% and breast cancer risk by 22%.”

Earlier this year, the AJC article continues, “researchers from the Harvard T.H. Chan School of Public Health found sugary drinks were linked to higher risk of early death, especially for women.”

But lead researcher Dr. Mathilde Touvier told The Guardian that “it’s probably safe to drink soda or fruit juice on occasion,” according to a story by Stephen Johnson on the Big Think website. “The recommendation from several public health agencies,” she’s quoted as saying, “is to consume less than one drink per day. If you consume from time to time a sugary drink it won’t be a problem, but if you drink at least one glass a day it can raise the risk of several diseases — here, maybe cancer, but also with a high level of evidence, cardiometabolic diseases.”  

A handful of U.S. cities — including Albany, Berkeley and San Francisco in California; Boulder, Colorado; Philadelphia; and Seattle — have levied taxes on the soda industry. “Those levies seem to decrease soda consumption,” Johnson’s piece says.

The Big Think article also notes that “although consuming large amounts of sugar has been linked to some forms of cancer, like esophageal cancer, there’s no strong evidence showing that it causes the disease, according to the American institute for Cancer Research. But there is an indirect link: Eating high-sugar foods often leads to obesity, which, in turn, raises the risk of developing cancer.”
