American kitchens have never been more full, and American hearts have never been sicker. The grocery store is stocked floor to ceiling. Dinner is thirty seconds away in the microwave. The snack drawer is always restocked before it empties. And somewhere in that abundance, something has gone profoundly wrong – not dramatically, not all at once, but through the kind of slow accumulation that is almost impossible to see when you are living inside it. The food feels normal. The problem is that by the time most people take it seriously, it has been building for years, not through dramatic failure, but through the kind of gradual erosion that is invisible precisely because it looks like ordinary Tuesday lunch.

Dr. Philip Ovadia is a board-certified cardiac surgeon who has spent years operating on hearts that the standard American diet had been quietly dismantling long before the patient arrived on his table. His position is not the standard issue “eat more vegetables” line. He is talking specifically about a category of food that has colonized the modern pantry so completely that most people no longer think of it as a category at all. Ultra-processed food. The stuff in boxes, bags, and brightly colored wrappers that makes up the majority of what Americans eat every day.

His argument is blunt in the way that arguments only get when someone has seen enough of the consequences. The operating table, he has said repeatedly, is too late. The damage that leads to it starts decades earlier, in the kitchen.

The Number That Should Get Your Attention

According to the CDC, heart disease claimed 683,491 lives in the United States in 2024, outpacing cancer, which accounted for 619,876 deaths. Heart disease is the leading cause of death for men, women, and people of most racial and ethnic groups – and one person dies from cardiovascular disease every 34 seconds.

Heart disease has held that position since 1950. Decades of pharmaceutical advances, surgical innovation, and public health campaigns have not dislodged it. That is not an argument for nihilism – it is an argument for paying closer attention to what has not changed in all that time. The American diet, broadly speaking, has not changed for the better. And the category of food now drawing the most sustained scrutiny from cardiologists is the one that most people encounter three times a day without giving it a second thought.

What “Ultra-Processed” Actually Means

The term ultra-processed gets thrown around a lot, to the point where it has started to feel vague. A cleaner way to think about it: if you cannot identify where the food came from by looking at the ingredient list, it probably qualifies. As Dr. Philip Ovadia himself puts it on his site, ultra-processed foods are anything technically edible but heavily altered from their original form – you cannot look at a Twizzler and really know where it came from, or grow a Snickers bar in your backyard.

The technical framework researchers use is called the Nova classification system, which organizes foods into four groups based on how much industrial processing they have undergone. Under this system, ultra-processed foods are industrially manufactured products derived from natural foods or other organic constituents, typically containing significant quantities of food additives, including preservatives, colorants, and flavor enhancers. Common examples include commercially produced breads, sugar-sweetened beverages, potato chips, chocolate confectionery, candy, and packaged cookies.

The scope of how much of this people are actually eating is striking. Ultra-processed foods have become a staple of the American diet: roughly 57 percent of the calories that American adults consume now comes from UPFs, a figure that rises to 67 percent in American children. When the majority of your daily calories come from a single food category, what that category does to the body becomes very consequential – a point the research has been underscoring with increasing force.

What the Research Is Finding

The most recent and authoritative word on this comes from May 2026. A report published in the European Heart Journal on May 7, 2026 found that people who eat more ultra-processed food have a higher risk of cardiovascular disease and death. The report combines findings from all currently available research examining the connection between UPFs and cardiovascular disease, and researchers found growing evidence linking high consumption of UPFs to obesity, diabetes, high blood pressure, chronic kidney disease, and death related to cardiovascular conditions.

The authors are urging doctors to discuss UPF intake with patients and offer practical advice on reducing consumption as part of routine healthcare – which is notable, because it signals that the medical establishment is shifting from treating the consequences of this diet to trying to interrupt it upstream.

Crucially, the European Heart Journal report also found that the poor nutritional composition of ultra-processed foods alone does not fully account for their adverse health impact. Over 75 prospective studies reported that UPF consumption was associated with an increased risk of chronic diseases even after adjusting for markers of nutritional quality such as energy, sugar, salt, and saturated fats. In plain terms: it is not just the sugar or the salt or the bad fat. Something else about how these foods are made – the additives, the industrial processes, the packaging – appears to contribute independently to cardiovascular harm. That is a harder thing to explain away.

A separate systematic review presented at the American College of Cardiology’s Asia 2025 scientific meeting found that ultra-processed food consumption was associated with hypertension, cardiovascular events, cancer, and digestive diseases – and that this risk increased with every 100 grams of ultra-processed foods consumed each day. There is no safe floor here. The relationship is dose-dependent, which means every portion counts in a way that cumulative eating across a lifetime makes deeply uncomfortable to reckon with.

The Insulin Resistance Argument

Where Dr. Ovadia’s position adds something specific to the broader UPF conversation is his focus on insulin resistance as the central mechanism driving heart disease. Insulin resistance is a condition where the body’s cells stop responding effectively to insulin, forcing the pancreas to produce increasingly large amounts of it just to keep blood sugar in a normal range. As this process continues unchecked, it creates the conditions for both type 2 diabetes and cardiovascular damage – not suddenly, but through a chain of metabolic events that can unfold across years without obvious symptoms.

Ovadia argues that when people talk about meat causing heart disease, they are really describing the context of a standard Western diet, which is high in refined carbohydrates and processed foods. “That is what is causing the harm,” he has said – and that a whole real food, low-carbohydrate dietary approach is the best way to address insulin resistance and inflammation, which he sees as the true root causes of heart disease.

The European Heart Journal report supports a version of this framing, noting that UPFs contribute to a causal chain in which dietary exposure leads to intermediate cardiometabolic risk factors – obesity, hypertension, dyslipidaemia, and insulin resistance – which then drive cardiovascular disease.

This is not a fringe view. The relationship between insulin resistance and the heart has been the subject of substantial peer-reviewed work. The body’s ability to regulate blood sugar affects the health of blood vessels, the lining of arteries, and the heart’s own energy supply. When that regulation fails, the cardiovascular system pays a long-term price, often silently, across years.

The “Healthy” Packaging Problem

One of the more uncomfortable implications of Ovadia’s warnings is that the foods causing the most harm are often not the ones people already know to avoid. They are the ones with words like “fortified,” “whole grain,” “low-carb,” or “high-protein” on the front of the box.

Ovadia has specifically called out ultra-processed “health” foods hiding in plain sight – from protein-fortified junk foods and low-carb breads to sugar-free products and trendy beverages – describing how healthwashing marketing can undermine genuine attempts at better eating. The marketing is doing work that the ingredients cannot support. A protein bar made from a list of chemical compounds the human body has never encountered before is not a health food, regardless of how many grams of protein it contains per serving.

This is where the conventional “just read the label” advice runs into its limits. Most people do not know what maltodextrin, carrageenan, or sodium stearoyl lactylate are. The very design of ultra-processed food relies on that gap between the appearance of something wholesome and what it actually contains. Ovadia’s broader point is that if your great-grandmother would not recognize what is in your shopping cart as food, that is probably information that deserves a second look.

What Dr. Ovadia Actually Eats

Ovadia’s dietary approach is worth understanding on its own terms, because it is genuinely unusual coming from a cardiac surgeon. He challenges the decades-old recommendation to avoid saturated fat such as red meat as a “misconception,” and eats a diet he describes as more than 95 percent animal-based, built around meats of all sorts, seafood, eggs, and dairy.

This places him well outside mainstream dietary guidance, and it is worth being honest about that. Organizations like the American Heart Association still recommend limiting saturated fat intake to avoid raising LDL cholesterol. Ovadia disputes that connection, arguing the science linking red meat to heart disease was misinterpreted. The scientific community has not reached consensus on this, and people with specific health conditions should discuss major dietary changes with their own physicians. What is far less contested, and what his position shares with the broader research base, is the role of ultra-processed foods in driving cardiovascular harm. The independent evidence for that part of the argument – whatever one thinks about carnivore diets – is substantial and consistent.

What Actually Changes When You Reduce UPFs

The practical question is not really “what does the research say” – the research, at this point, says it clearly enough. The question is what happens when people actually eat less of this food, and whether the benefit is worth the effort.

A multi-centre analysis of nearly 430,000 participants across nine European countries, published in The Lancet in January 2025, found that ultra-processed foods were positively associated with all-cause mortality, as well as deaths from circulatory diseases and ischemic heart disease. The same study found that replacing processed and ultra-processed foods with unprocessed or minimally processed foods was associated with lower mortality risk.

That is not a small finding. It means the benefit is not hypothetical or theoretical. It appears in the actual death data across hundreds of thousands of real people, across different countries, different healthcare systems, and different culinary cultures. The direction of the evidence has become remarkably consistent.

None of this requires a perfect diet or an overnight overhaul of everything in the kitchen. The research does not suggest an all-or-nothing threshold. The dose-dependent nature of the risk means that every meaningful reduction in UPF consumption points somewhere better, even if it does not point to perfect.

The Thing Nobody Says Out Loud

The really uncomfortable part of all this is not learning that ultra-processed food is bad for the heart. Most people already suspect as much. The uncomfortable part is the scale of how normal these foods have become, and how little the healthcare system has done to interrupt that normality at the source.

European cardiology experts are now explicitly calling on doctors to discuss UPF intake with patients during routine healthcare visits – which suggests this conversation has largely not been happening. People with high blood pressure or elevated cholesterol are handed medications and instructed to “watch what they eat,” with little practical support for what “watching” should actually look like in a supermarket full of products designed to be both appealing and confusing.

Dr. Ovadia’s point is sharper than that. He spent years performing surgeries on hearts that diet had been slowly undermining, and his conclusion is that no amount of intervention on the back end can substitute for what does not happen on the front end. The operating table is too late. The conversation about what is in the pantry is the earlier one, and for most people, it has not happened in anywhere near the right terms.

You do not have to adopt a carnivore diet to take the core argument seriously. You do not have to believe every claim Ovadia makes about red meat and saturated fat to accept that the thing keeping heart disease at the top of the mortality charts for 75 years might have something to do with the food that looks the most normal, fills the most grocery aisles, and is the most aggressively marketed as the safe, convenient choice. The archive of cardiovascular damage does not shrink on its own. It just keeps accumulating, one Tuesday lunch at a time.
