United States President Donald Trump has claimed that diet soft drinks could potentially eliminate cancer cells.

This was revealed in a podcast interview with Dr Oz, who heads Centres for Medicare and Medicaid Services.

Nutritionist Nikki Hart has disputed this claim - and says it's 'alarming' that the US President is saying this. 

"We know that non-nutritive sweeteners in diet drinks - there's no cause or link to cancer, but then you can't just flip it and go, oh well, I can drink lots of this because it kills cancer."
