Study linking cancer and sweetener consumption sparks controversy among scientists

Scientists from the French National Institute of Health and Medical Research (Inserm) and

Northern Sorbonne University in Francesuggest that some artificial sweeteners are associated with an increased risk of cancer. They used data from the NutriNet-Santé project, which started in 2009. Its goal is to track the relationship between diet and health in more than 100,000 French people.

They discovered a connection between sugar substitutes,such as aspartame or acesulfame-K, and an increased risk of cancer. The authors of the new study are calling on food safety regulators to re-evaluate these artificial sweeteners.

A new study has led toThe decades-long debate about the safety of artificial sweeteners has flared up again. Experts not associated with the study argue that the results are insufficient. Skeptics believe that the authors of the new study mistakenly associated causation with correlation.

During the experiment every six monthsparticipants filled out three 24-hour food diaries listing everything they ate during the day, including information about commercial brands. It turned out that study participants who consumed a lot of artificial sweeteners were more likely to be diagnosed with cancer than those who did not consume artificial sweeteners (or a small amount). In particular, aspartame and acesulfame-K have been linked to a higher risk of developing breast cancer and other cancers.

"Our results do not support the useartificial sweeteners as a safe alternative to sugar in food or beverages and provide important and new information for resolving disputes about their potential adverse health effects,” the researchers concluded in an article for the journal PLos medicine.
