Ultra-Processed Foods Linked to Significantly Increased Risk of Heart Disease and Stroke
The modern diet, increasingly dominated by convenience and affordability, is facing growing scrutiny. A substantial body of research now points to a concerning link between the consumption of ultra-processed foods (UPFs) and a heightened risk of cardiovascular disease, including heart attack and stroke. While dietary recommendations have long emphasized limiting saturated fats and sugars, the focus is shifting to the very *processing* of food itself. New data, including a recent study from Florida Atlantic University, suggests that individuals with the highest intake of these foods face a 47% greater risk of developing cardiovascular disease. This finding underscores the urgent need to understand the impact of UPFs on public health and to develop strategies to promote healthier eating patterns.
Cardiovascular disease remains a leading cause of death globally, accounting for an estimated 17.9 million deaths each year, according to the World Health Organization. The WHO emphasizes that a significant proportion of these deaths are preventable through lifestyle modifications, including dietary changes. The rising prevalence of UPFs in our diets, now constituting a majority of food purchases in many countries, presents a significant challenge to these preventative efforts. Understanding the specific mechanisms by which these foods contribute to cardiovascular risk is crucial for informing both individual choices and public health policies.
Defining ultra-processed foods can be complex. Generally, they are industrial formulations made with ingredients not typically used in home cooking – additives, preservatives, emulsifiers, and often high levels of sugar, salt, and unhealthy fats. Common examples include sugary drinks, packaged snacks, processed meats, and many ready-to-eat meals. These foods are often designed to be hyper-palatable, encouraging overconsumption, and are frequently stripped of essential nutrients during processing. The American Heart Association recommends minimizing the intake of ultra-processed foods as part of a heart-healthy eating pattern. Their 2026 fact sheet details the growing concerns surrounding UPF consumption and its impact on cardiovascular health.
New Research Highlights the Cardiovascular Risk
Researchers at Florida Atlantic University’s Charles E. Schmidt College of Medicine recently investigated the association between ultra-processed food intake and cardiovascular disease risk. Their study, published in The American Journal of Medicine, analyzed data from the U.S. National Health and Nutrition Examination Survey (NHANES) collected between 2021 and 2023. The analysis included 4,787 adults aged 18 and older, all of whom provided detailed dietary records and information on any prior heart attack or stroke diagnoses. Participants were categorized into four groups based on their level of UPF consumption, ranging from lowest to highest.
The study revealed a statistically significant correlation: individuals in the highest group of ultra-processed food consumption exhibited a 47% higher risk of cardiovascular disease compared to those in the lowest intake group. This risk remained elevated even after adjusting for factors such as age, sex, race and ethnicity, smoking status, and income. According to Charles H. Hennekens, M.D., FACPM, FACC, senior author of the study and First Sir Richard Doll Professor of Medicine and Preventive Medicine at FAU, these findings have “major implications for future research as well as clinical care and public policy.”
The researchers also conducted a secondary analysis involving approximately 1.25 million adults, finding similar results regarding cardiovascular and coronary artery disease. Notably, this larger analysis also indicated a 9% increased risk of stroke among those with the highest UPF consumption. The study specifically identified sugary drinks and processed meat, poultry, and fish as driving the majority of the observed health risks. Interestingly, the research also suggested that certain ultra-processed foods, such as breakfast cereals, flavored yogurts, frozen yogurt, and packaged snacks like popcorn and crackers, were linked to a *reduced* risk of cardiovascular disease, though researchers caution against interpreting this as a blanket endorsement of these products.
Understanding the Mechanisms at Play
While the Florida Atlantic University study establishes a strong association, it does not definitively prove causation. Still, a growing body of evidence suggests several mechanisms by which ultra-processed foods may contribute to cardiovascular disease. Previous research has linked high UPF consumption to metabolic syndrome, a cluster of conditions including obesity, high blood pressure, abnormal cholesterol levels, and insulin resistance – all major risk factors for heart disease. Johns Hopkins Bloomberg School of Public Health explains that UPFs are associated with a long list of adverse health outcomes.
high intake of UPFs has been associated with elevated levels of high-sensitivity C-reactive protein (hs-CRP), a marker of inflammation. Chronic inflammation is increasingly recognized as a key driver of atherosclerosis – the buildup of plaque in the arteries – which underlies many forms of cardiovascular disease. The additives and ingredients unique to ultra-processed foods may trigger inflammatory responses in the body, contributing to this process. The removal of naturally occurring nutrients during processing may also deprive the body of protective compounds that aid regulate inflammation and maintain cardiovascular health.
The Parallel to Tobacco and the Need for Public Health Intervention
The researchers draw a compelling parallel between the growing awareness of the health risks associated with ultra-processed foods and the historical struggle to address the dangers of tobacco. Just as it took decades for the scientific evidence linking smoking to cancer and heart disease to be widely accepted and acted upon, reducing reliance on UPFs may require a sustained and multifaceted public health effort. This is complicated by the powerful influence of large multinational food companies that dominate the market and often prioritize profit over public health.
Addressing UPF consumption isn’t solely about individual choices, according to Dr. Hennekens. “Addressing UPFs isn’t just about individual choices — it’s about creating environments where the healthy option is the straightforward option,” he stated. This requires a combination of clinical guidance, public health education, and policies that make nutritious foods more accessible and affordable for all. Potential interventions could include taxes on sugary drinks and highly processed foods, subsidies for fruits and vegetables, and stricter regulations on food marketing aimed at children.
Beyond Cardiovascular Disease: Links to Other Health Concerns
The potential health consequences of high UPF consumption extend beyond cardiovascular disease. The researchers also point to rising rates of colorectal cancer, particularly among younger adults, as a potential area of concern. Many of the risk factors for colorectal cancer overlap with those for cardiovascular disease, including dietary patterns and chronic inflammation. The increasing consumption of UPFs may contribute to this trend, alongside other dietary and lifestyle factors.
The study’s co-author, Allison H. Ferris, M.D., FACP, professor and chair of the Department of Medicine at FAU Schmidt College of Medicine, emphasized that “Awareness is the first step toward prevention.” Further research is needed to fully elucidate the complex relationship between UPF consumption and various health outcomes, but the existing evidence strongly suggests that reducing intake of these foods is a prudent step towards improving overall health and well-being.
Key Takeaways
- A recent study found a 47% higher risk of cardiovascular disease among individuals with the highest intake of ultra-processed foods.
- Sugary drinks and processed meats were identified as major contributors to this increased risk.
- Ultra-processed foods are often high in sugar, salt, and unhealthy fats, and low in essential nutrients.
- Public health interventions, such as taxes and subsidies, may be necessary to reduce UPF consumption.
- Reducing intake of ultra-processed foods is a proactive step towards improving cardiovascular health and overall well-being.
While large-scale randomized controlled trials are still needed to definitively confirm these findings, healthcare providers can begin advising patients now to reduce their consumption of ultra-processed foods as part of a broader strategy for promoting heart health. The ongoing research into the impact of UPFs on health is expected to continue, with further studies planned to investigate the specific mechanisms involved and to evaluate the effectiveness of various intervention strategies. The next major update from the Florida Atlantic University research team is anticipated in late 2026, following a more detailed analysis of the NHANES data.
