The Bizarre Eating Habits of the US President

When the leader of the free world starts his day with a candy bar and a button that dispenses diet cola, it’s hard not to wonder what ripple effects such habits might have far beyond the Oval Office. The recent revelations from Dr. Mehmet Oz on Donald Trump Jr.’s podcast—where the former CMS administrator shared that the President believes diet soda kills cancer cells because it wilts grass when sprayed on lawns—might sound like a bizarre footnote in White House lore. But for communities grappling with rising rates of diet-related illness and soda consumption, especially in places where public health messaging is already strained, this kind of misinformation isn’t just a curiosity. It’s a case study in how influential figures can unintentionally amplify harmful myths, even as real experts work to counter them.

Consider a city like San Antonio, Texas, where the prevalence of diabetes exceeds the national average and where sugary drink consumption remains a persistent challenge in public health campaigns. In neighborhoods like the South Side or along the Mission Trail corridor, community health workers already face an uphill battle educating residents about nutrition, often pushing back against myths that equate “diet” or “sugar-free” with inherently healthy. Now, imagine trying to explain why a zero-calorie soda doesn’t neutralize cancer cells while a nationally televised figure—backed by the credibility of a TV doctor—suggests otherwise. It creates a cognitive dissonance that undermines months of outreach, particularly when the President’s habits are framed not as eccentricities but as evidence of vitality, as Oz noted when he described Trump as “extremely fit for his age” despite the unconventional breakfast of candy bars and diet cola.

This isn’t merely about one man’s preferences. It touches on broader patterns of how health misinformation spreads, especially when wrapped in folksy logic. The idea that because something affects one biological system (like plant cells) it must affect another (like human tumor cells) in the same way is a classic false analogy—one that ignores the vast complexity of human metabolism, oncology, and pharmacology. And yet, in an era where trust in institutions fluctuates, such narratives can gain traction not because they’re scientifically sound, but because they experience intuitive, are repeated with confidence, and reach from familiar faces. Dr. Oz himself, a figure long associated with mainstream media through his Oprah Winfrey Show appearances and later scrutinized for promoting unproven treatments, adds a layer of irony: his role as a trusted health communicator is now entangled with the dissemination of a claim that medical consensus rejects outright.

In Bexar County, where the University Health System and the San Antonio Metropolitan Health District run programs like ¡Por Vida! to promote healthier menu options in restaurants and the Healthy Corner Store Initiative to increase access to fresh produce in food deserts, the stakes are clear. When national figures promote unverified health theories, it doesn’t just confuse individuals—it strains local infrastructure. Clinicians spend more time debunking myths; public health budgets get redirected toward education campaigns that counteract misinformation; and trust in legitimate guidance erodes. The ripple effect extends to schools, where children might hear conflicting messages about what constitutes a healthy drink, and to workplaces, where wellness programs must now contend with the lingering influence of celebrity-endorsed pseudoscience.

Given my background in community health journalism, if this trend of influential figures shaping public perception of nutrition impacts you in San Antonio, here are the three types of local professionals you need to know about—and exactly what to look for when seeking their guidance.

First, seek out Registered Dietitians (RDs) specializing in community nutrition, particularly those affiliated with institutions like the UT Health San Antonio School of Nursing or working through the Metro Health Department’s chronic disease prevention units. The best ones don’t just hand out meal plans—they understand cultural foodways, speak the language of the communities they serve (whether that’s Spanish-dominant households on the West Side or military families near Fort Sam Houston), and can debunk myths using relatable analogies without talking down. Look for credentials like LDN (Licensed Dietitian Nutritionist) in Texas and ask whether they have experience leading group workshops in settings like libraries, churches, or schools—proof they translate science into action.

Second, connect with Public Health Educators focused on health literacy and misinformation resilience, ideally those embedded in organizations like the San Antonio AIDS Foundation or the Baptist Health System’s community outreach arm. These professionals go beyond traditional teaching; they’re trained in prebunking—anticipating false claims before they spread—and use tools like motivational interviewing to help residents navigate conflicting information. When evaluating them, prioritize those who cite real-world examples from local media (like KSAT or the San Antonio Report) in their training materials and who collaborate with promotoras or peer educators, ensuring their approach is grounded in trust, not top-down lectures.

Third, consider Clinical Pharmacists with ambulatory care specialization, especially those practicing in Federally Qualified Health Centers (FQHCs) like those operated by CentroMed or CommuniCare Health Centers. Often overlooked, these clinicians are uniquely positioned to address nutrition myths because they manage medications where diet interactions matter—think blood thinners and leafy greens, or diabetes medications and grapefruit. The best ambulatory care pharmacists in San Antonio will routinely discuss beverage habits during medication therapy management (MTM) sessions, use teach-back methods to confirm understanding, and collaborate with dietitians on integrated care plans. Look for BCACP (Board Certified Ambulatory Care Pharmacist) credentials and verify they accept your insurance or offer sliding-scale fees—many FQHCs do.

These three archetypes aren’t just service providers—they’re neighborhood defenders against the gradual creep of health misinformation, armed not with judgment but with evidence, empathy, and deep local roots. They understand that in a city where the River Walk draws millions but food insecurity persists in pockets just miles away, health guidance must be both scientifically rigorous and culturally resonant.
