Ultra-processed foods (UPFs), including packaged snacks, sugar-sweetened beverages, ready-to-eat meals and processed meats, have become dominant in modern eating patterns, particularly in high-income countries. Characterised by high levels of added sugars, unhealthy fats, sodium, and synthetic additives, UPFs undergo extensive industrial processing that strips them of nutritional integrity while enhancing shelf life and palatability. Mounting epidemiological and clinical evidence underscores a robust association between high UPF consumption and adverse cardiovascular outcomes.
Mechanistically, UPFs contribute to cardiometabolic dysregulation through several pathways. Chronic low-grade inflammation, gut microbiome disruption, insulin resistance and hypertension are detected more frequently in individuals with high UPF intake. Moreover, the energy-dense, nutrient-poor profile of such foods fosters obesity, a major established independent risk factor for atherosclerosis and heart failure.
Several large-scale cohort studies, including data from the Nurses’ Health Study and the French NutriNet-Santé cohort, have demonstrated a dose-dependent relationship between UPF intake and increased incidence of cardiac disease and stroke. These findings persist even after adjusting for total caloric intake and other confounding lifestyle factors, suggesting that UPFs pose risks beyond traditional their dietary components.
For healthcare providers, this evidence reinforces the imperative to prioritise dietary quality in the practice of preventive medicine. Counselling clients to minimize UPF consumption – favouring whole, minimally processed foods – should be a central tenet of lifestyle intervention. As the food environment evolves, healthcare providers play a critical role in advocating for public health policies that reduce UPF availability and improve food labelling transparency.
