Ultra-processed foods have long been a staple in many people’s diets, but new research presented at the ACC Asia 2025 Together with SCS 36th Annual Scientific Meeting suggests that these foods may be linked to adverse health outcomes. The study, conducted by Xiao Liu, MD, from Sun Yat-sen Memorial Hospital of Sun Yat-sen University in Guangzhou, China, found that consumption of foods such as sugar-sweetened beverages, potato chips, and packaged cookies may increase the risk of hypertension, cardiovascular events, cancer, digestive diseases, and even mortality.
According to Dr. Liu, ultra-processed foods are high in sugar, salt, and other non-nutritive components, while also being low in essential nutrients. These foods can lead to a range of health issues, including dysregulation of blood lipid profiles, alterations in gut microbiota composition, obesity, inflammation, oxidative stress, and insulin sensitivity.
The systematic review included 41 prospective cohort studies involving over 8 million adult patients from various regions around the world. The studies defined ultra-processed foods as industrially manufactured products with high levels of additives and low nutritional value. Examples of these foods include bread, sugary drinks, potato chips, chocolate, candy, and packaged cookies.
The study found that for every 100 grams of ultra-processed foods consumed daily, there was an increased risk of hypertension, cardiovascular events, cancer, digestive diseases, and mortality. The researchers also noted a higher risk of obesity, metabolic syndromes, diabetes, and mental health issues associated with ultra-processed food consumption.
Dr. Liu emphasized the importance of reducing the intake of ultra-processed foods and replacing them with more nutritious options. He suggested that governments implement measures to regulate food labeling and ingredient disclosures to help consumers make healthier choices. Clinicians should also encourage patients to adopt healthier eating patterns, such as the Mediterranean or DASH diet.
While the study had limitations in terms of generalizability and comparability due to varying definitions of ultra-processed foods, Dr. Liu highlighted the importance of focusing on whole foods and simple ingredients for better health outcomes. Further research is needed to explore the benefits of healthy eating patterns and their impact on overall well-being.
In conclusion, reducing the consumption of ultra-processed foods may offer significant health benefits. By making small changes to our diets and choosing whole, minimally processed foods, we can improve our overall health and well-being. The findings from this study serve as a reminder to prioritize nutritious foods for a healthier lifestyle.
