For decades, the conversation in a cardiologist’s office centered on specific nutrients: too much saturated fat, not enough fiber, or a spike in LDL cholesterol. But a new clinical consensus is shifting the focus from individual ingredients to how our food is made. The emerging priority is the reduction of ultra-processed foods (UPFs)—industrial formulations that often bear little resemblance to the raw ingredients they started with.
In a new clinical consensus statement published in the European Heart Journal, the European Society of Cardiology (ESC) and the European Association of Preventive Cardiology (EAPC) are urging heart specialists to change how they counsel patients. The directive is clear: doctors should move beyond generic dietary advice and provide practical, behavioral strategies to help patients strip UPFs from their daily routines.
The urgency is driven by a growing body of evidence linking these foods to a cascade of metabolic failures. For the millions of people living with cardiovascular disease—including an estimated 8 million in the UK alone—the habitual consumption of UPFs is no longer viewed as a mere lifestyle choice, but as a significant clinical risk factor for heart attack, stroke, and chronic kidney disease.
Defining the Danger of Ultra-Processing
To understand why cardiologists are sounding the alarm, it is necessary to distinguish between “processed” and “ultra-processed.” While frozen vegetables or canned beans are processed for preservation, ultra-processed foods are industrial concoctions. They typically contain substances not used in home kitchens—such as hydrogenated oils, high-fructose corn syrup, flavor enhancers, and emulsifiers—designed to maximize shelf life and hyper-palatability.
From a clinical perspective, the danger of UPFs is twofold. First, they are typically “nutrient-poor,” lacking the fiber and micronutrients that protect the vascular system. Second, they are often engineered to bypass the body’s natural satiety signals. This leads to overconsumption, which fuels the obesity and type 2 diabetes that frequently precede heart failure.
Prof. Luigina Guasti, a co-author of the consensus paper, notes that the shift toward home-prepared meals is one of the most effective interventions. “Evidence shows that people who cook more meals at home tend to have better overall diet quality and eat less ultra-processed food,” Guasti said. She emphasized that health improvements do not require an overnight overhaul; even small, gradual increases in home-cooked meals can yield cumulative benefits over time.
A New Protocol for Patient Care
The ESC and EAPC guidelines suggest that cardiologists should integrate UPF counseling into routine outpatient visits and lifestyle assessments. Rather than simply telling a patient to “eat healthy,” the consensus statement encourages a more diagnostic and visual approach to nutrition.
One of the more striking recommendations is the use of visual aids. The statement suggests that showing patients images of common UPFs found in supermarkets is far more effective than verbal explanations. This helps patients recognize “hidden” ultra-processed foods—such as certain flavored yogurts or packaged snack bars—that they may have previously perceived as healthy.
Beyond what is on the plate, the guidelines highlight how and when we eat. Doctors are encouraged to discuss the benefits of avoiding late-night eating and practicing mindful, slower chewing. These behaviors enhance satiety, making it easier for patients to resist the urge to reach for highly palatable, processed snacks during evening hours.
Dr. Kawther Hashem, a senior lecturer in public health nutrition at Queen Mary University of London, argues that these conversations must be grounded in the reality of the patient’s life. “Doctors should be having much more practical conversations… Encouraging people to cook more at home where they can, although this can often be difficult,” Hashem said. She specifically pointed to the danger of salt in ready meals and takeaways, which directly elevates blood pressure and increases the risk of stroke.
Practical Shifts: From Industrial to Minimal
For patients and the general public, the transition away from UPFs does not require a degree in nutrition. The consensus statement suggests a series of simple, high-impact swaps that reduce the chemical load on the heart and kidneys.
| Instead of this UPF… | Try this Minimally Processed Alternative… | Primary Heart Benefit |
|---|---|---|
| Sugary sodas & energy drinks | Water or sparkling water with citrus | Lower blood sugar & weight risk |
| Flavored or sweetened yogurts | Plain Greek yogurt with fresh fruit | Reduced added sugars |
| Processed meats (sausages, deli) | Fresh poultry, fish, or legumes | Lower sodium & nitrates |
| Packaged snacks & ready meals | Home-cooked grains and vegetables | Increased fiber & salt control |
Reading labels is another critical tool. Patients are advised to scrutinize the ingredient list of any tin, packet, or sachet. A general rule of thumb provided by nutritionists is that if a product contains ingredients that you would not find in a standard home pantry, it is likely ultra-processed.
The Limits of Individual Willpower
While the clinical focus is on patient counseling, experts warn that individual effort can only go so far in a “toxic” food environment. The ubiquity and low cost of UPFs often make them the only viable option for low-income families or those living in “food deserts.”
Tracy Parker, a senior dietitian at the British Heart Foundation, emphasizes that the burden of health should not rest solely on the patient. She argues that government intervention is necessary to create a healthier food environment, suggesting that policy changes—such as taxes on ultra-processed goods or stricter labeling laws—are required to support the clinical goals set by cardiologists.
The systemic challenge is significant. When ultra-processed foods are cheaper and more accessible than fresh produce, the “clinical consensus” to cook at home becomes a socioeconomic struggle as much as a medical one.

As the medical community continues to track the long-term impact of industrial food systems, the next phase of this effort will likely involve larger-scale longitudinal studies to quantify exactly how much a reduction in UPFs can lower the rate of cardiovascular mortality. For now, the directive for heart patients is simple: return to the kitchen and read the label.
