Dr. Oz Says Trump Argues That Diet Soda Is ‘Good for Him’ Because if It Kills Grass, It’ll Kill Cancer Cells

President Donald Trump reportedly views his well-documented diet soda habit as a medical defense against cancer, according to new details shared by Dr. Mehmet Oz. The revelation comes as the administration’s own health officials launch an aggressive campaign to purge the American diet of the very processed ingredients the President consumes daily.

During an appearance on the Triggered podcast with Donald Trump Jr. on Monday, Oz—the current Administrator for the Centers for Medicare and Medicaid Services—recounted a recent exchange aboard Air Force One. Oz noted that when he questioned the President’s consumption of Fanta, Trump responded with a pseudo-scientific justification.

“You know, this stuff’s good for me, it kills cancer cells,” Oz quoted the President as saying. The President’s logic, according to Oz, is that because the beverage is caustic enough to kill grass, it must be effective in eradicating malignant cells within the human body.

The President’s comments highlight a growing tension between the Oval Office’s personal habits and the Department of Health and Human Services’ (HHS) official “Make America Healthy Again” (MAHA) platform.

In January, Health Secretary Robert F. Kennedy Jr. announced a rigorous reset of U.S. nutrition guidelines, prioritizing whole, nutrient-dense foods while urging Americans to “dramatically reduce” highly processed items. While the administration’s policy arm targets the “ultra-processed” food industry, the President has reportedly reinstalled his signature “Diet Coke button” in the Oval Office.

Trump, a self-described germaphobe, has long defended his preference for fast-food giants like McDonald’s and KFC as a matter of hygiene. Oz echoed this sentiment, suggesting the President views major chains as safer due to their rigid quality control and “cleanliness.”

Donald Trump Jr. dismissed concerns regarding his father’s diet, citing the 79-year-old’s “energy, recall, and stamina” as proof of his resilience. However, medical experts have repeatedly warned that the President’s claims lack any scientific basis. There is no evidence that carbonated soft drinks—whether diet or sugary—prevent or treat cancer. On the contrary, high consumption of processed additives is frequently linked to metabolic dysfunction.

The President’s recent “cancer-killing” quip mirrors previous instances where he has floated unverified medical theories. Most notably, in 2020, Trump faced a firestorm of criticism after suggesting that injecting disinfectants could potentially treat COVID-19.

As the HHS prepares to dismantle the traditional food pyramid in favor of Kennedy’s whole-food model, the President’s personal endorsement of soda remains a point of domestic policy friction. The White House did not respond to requests for comment regarding the scientific validity of the President’s remarks.
