President Trump has a bizarre theory that Diet Coke may kill cancer cells in his body, according to Centers for Medicare & Medicaid Services Administrator Dr. Mehmet Oz. Oz recalled that Trump, who has a habit of showing off his candy stash and bringing in a diet soda when meeting with his peers, and Health and Human Services Secretary Robert F. Kennedy Jr. Both have been involved in the Make America Healthy Again movement, which aims to inspire Americans to improve their diet habits. However, attempts to push Trump to change his dieting have fallen flat. Despite this, Oz suggested that Trump is healthy and that his testosterone was through the roof without taking supplements.
