A physician writing in The Daily Wire is making the case that the Washington fascination with Health and Human Services Secretary Robert F. Kennedy Jr.’s diet — the sauerkraut, the relentless protein, the visibly fit 71-year-old frame — is masking a more serious conversation about what food does to the human body.
Dr. Benjamin Chacko, identified in the piece as an emergency physician, writes that an autoimmune issue pushed him to overhaul his own eating habits, and the results were striking enough that he began describing the experiment as a clinical trial with a single subject.
The sauerkraut running joke
Kennedy’s dietary habits have become something of a running gag in Washington. According to the account, Vice President JD Vance joked from the White House podium that anyone who wants to lose weight should call Bobby Kennedy, while anyone who wants to enjoy their food should not. Kennedy’s wife has reportedly said he brings his own sauerkraut to restaurants.
The piece acknowledges Kennedy’s eccentricities — the swims in Rock Creek, the dead bear abandoned in Central Park — while noting that conventional thinking has rarely been his strength. But it argues those same habits are worth examining on their merits.
What the doctor says changed
Chacko describes a familiar American pattern: a lifelong taste for sugar, a donut after an overnight shift, and a crash 90 minutes later. A sandwich on brioche, a bag of chips, or a bowl of pasta each sent him toward a nap he assumed was simply how his body worked. He says he never connected the dots.
Despite what he calls his “evidence-based” instincts as a physician, he cut carbohydrates and gluten and shifted toward meat, vegetables, and fermented foods. The afternoon crashes stopped. So did the irritability, the scattered focus, and the disrupted sleep. He reports a dose-response effect — the fewer carbs he ate, the better he felt — and says his family noticed he had become easier to be around.
His own summary of the transformation is blunt: after years of practicing medicine, he had never fully appreciated how much diet shapes energy, mood, and behavior.
The biology behind the claims
The article lays out a simplified version of the gut-health argument that has circulated in wellness and functional-medicine circles for years. The intestinal lining, it explains, functions as a border wall between the bloodstream and the outside world, with the immune system screening every molecule that tries to cross. A microbiome of roughly 38 trillion microorganisms occupies the moat around that wall, helping digest food, produce biologically active compounds, and communicate with the immune system.
When food choices lean heavily on sugar and processed ingredients, the piece argues, that barrier weakens, and inflammation or autoimmune problems can follow. It also notes that most serotonin is produced in the gut and that microbes generate compounds involved in metabolic and neurotransmitter signaling — the reason scientists sometimes call the gut a “second brain.”
Sauerkraut, in this telling, helps in three ways: the soluble fiber in cabbage feeds beneficial bacteria, fermentation introduces more good bacteria, and those bacteria produce short-chain fatty acids such as butyrate that nourish the cells lining the colon.
The piece points to a Stanford study finding that a fermented-food diet increased microbiome diversity and reduced several markers of inflammation, while cautioning that this does not mean sauerkraut cures disease.
On the low-carb side, the article explains that carbohydrates raise insulin, which pushes glucose into cells but also signals the body to store fat. When carb intake drops low enough, the liver produces ketones from fat as an alternative fuel. It notes that ketogenic diets have an established medical role in certain forms of epilepsy alongside medication, can improve blood glucose and weight in some people with type 2 diabetes, and are being studied for neurological and psychiatric conditions — though that evidence remains preliminary.
A critique of medical training
The broader argument is aimed less at Kennedy than at the medical establishment. The piece contends that America’s burden of obesity, diabetes, and cardiovascular disease — conditions heavily influenced by diet — has helped push U.S. mortality above other developed nations, even as the profession remains, in the author’s words, embarrassingly ignorant about nutrition.
His prescription: medical education, and residencies in particular, should treat food the way they treat pharmacology. Students should learn how diet affects human health with the same rigor they apply to drugs, because in a real sense, food is medicine.
He is careful to add caveats. Not everyone should eat steak and sauerkraut. Ketogenic diets are not appropriate for everyone and can substantially raise LDL cholesterol in some patients. Fermented foods are not miracle cures. Individual conditions matter, and major dietary changes should be discussed with a clinician.
Still, the central complaint stands: the system has grown extraordinarily sophisticated at treating the consequences of poor metabolic health while remaining casual about one of its most important drivers. Food, he writes, is not merely a matter of calories and willpower.
Chacko admits he had to be dragged into eating better, convinced that diet had little effect on his problems. He says he was wrong — and that he is still eating this way because it worked.
The politics, he suggests, matter less than the health implications. But if a jar of fermented cabbage gets Americans thinking harder about the relationship between what they eat and how they feel, then perhaps, he concludes, Kennedy is onto something worth discussing.
