Sugary drinks, including 100% fruit juices and fizzy pops, appear to increase the risk of cancer (very slightly).
Gallagher, J. (2019). Are sugary drinks causing cancer? London: BBC Health News, July 11th 2019.
This relates to:
Chazelas, E. Srour, B. [and] Desmetz, E. [et al] (2019). Sugary drink consumption and risk of cancer: results from NutriNet-Santé prospective cohort. BMJ. July 10th 2019; 366: l2408.
An NHS Behind the Headlines appraisal examines this research:
“An 18% increase in risk may sound quite high, but it corresponds to 4 extra cases of cancer per every 1,000 people over a 5-year period”.
