Donald Trump claims soda can kill cancer cells, sparks online debate

Centres for Medicare and Medicaid Services' head, Dr Mehmet Oz, said US President Donald Trump once claimed that soda could help kill cancer cells. "Your dad argues...diet soda is good for him because it kills grass [when] it’s poured on grass...therefore, it must kill cancer cells,” Oz told Donald Trump's son, Donald Trump Jr. The claim has sparked debate online.
