Artificially sweetened drinks such as Diet Coke and a version of Red Bull could contain cell-destroying ingredients that increase your risk of cancer.
Diet Coke and Red Bull Sugarfree contain a sweetener known as sucralose, sold under the brand name Splenda, which when digested, becomes genotoxic, meaning it breaks up DNA.
As the sucralose reaches the gut, a chemical called sucralose-6-acetate is produced.
In a series of test tube experiments, researchers exposed human blood cells to sucralose-6-acetate, observing that it "effectively broke up DNA in cells that were exposed to the chemical".
They also exposed human gut tissues to sucralose and sucralose-6-acetate in a series of tests and found that both chemicals caused a "leaky gut" - meaning waste products usually flushed through our systems leak into the bloodstream.
Warning as popular food and drink ‘increase risk of cancer death by up to 30%’

Professor Susan Schiffman, of the North Carolina State University, explained: "Basically, they make the wall of the gut more permeable. The chemicals damage the ‘tight junctions,’ or interfaces, where cells in the gut wall connect to each other.
“A leaky gut is problematic, because it means that things that would normally be flushed out of the body in feces are instead leaking out of the gut and being absorbed into the bloodstream.”
The study also found sucralose-6-acetate had inflammation and carcinogenic effects.
