In a recent podcast, Donald Trump defended his habit of drinking diet soda by claiming it might help kill cancer cells. This assertion was made during a conversation with Mehmet Oz, who recalled Trump's comments about diet soda while on Air Force One. Oz humorously noted Trump's belief that if diet soda can kill grass, it could also kill cancer cells. Medical professionals, however, quickly dismissed these claims, reiterating that diet soda does not prevent or cure cancer. The International Agency for Research on Cancer (IARC) has categorized aspartame, a common sweetener in diet sodas, as 'possibly carcinogenic to humans.' A 2022 study involving over 100,000 participants indicated a 15% higher cancer risk linked to aspartame, though it did not establish a direct cause-and-effect relationship. Experts warn that while research continues, there is no scientific basis for the belief that diet soda can combat cancer. Doctors have urged the public to rely on proven medical advice rather than anecdotal claims.
