“A […] study suggests that sugar and sweetened drinks may raise the chances of this cancer by 70 percent or more.”
Despite their healthy image in the general population, fruit juices generally contain “high levels of simple sugar, and their glycemic indexes are higher than that of whole fruits,” writes the British Medical Journal.
Some fruit juices, however, have an inverse association with cancer however, meaning they may lower the risk.
For example, there is evidence that citrus fruit intake “substantially” reduces the risk of oesophageal cancer, according to research published in the journal Medicine (Baltimore).
