Sugary drink consumption and risk of cancer: results from the NutriNet-Sante prospective cohort study

18 / 09 / 19

Finding: In this French cohort, consumption of sugary drinks was associated with an increased overall risk of cancer.

Summary: The French NutriNet-Sante cohort of 101,257 adult participants were followed up over five years. Twenty-four hour diet records were designed to record consumption of sugary drinks (soft drinks and 100% fruit juices) and artificially sweetened beverages. Prospective associations between beverage consumption and risk of overall, breast, prostate and colorectal were assessed by hazard models. The consumption of sugary drinks was associated with overall cancer risk (each 100ml increase was associated with 1.18 hazard ratio {HR}, i.e. a risk increase), and breast cancer (1.22 HR), but was not associated with lung, prostate or colorectal cancers. In specific sub-analysis, consumption of pure fruit juice was significantly associated with overall cancer risk (1.18 HR); artificially sweetened drinks were not associated with cancer risk.
