Researchers at the Charles E. Schmidt College of Medicine at Florida Atlantic University analyzed national health and diet data to investigate the relationship between ultra-processed foods (UPFs) and cardiovascular events like heart attacks and strokes. UPFs, which include items such as sodas, packaged snacks, and processed meats, now constitute a significant part of the American diet and are associated with obesity, inflammation, and metabolic issues.

The study utilized data from nearly 4,800 adults participating in the National Health and Nutrition Examination Survey. It assessed the percentage of daily caloric intake from UPFs and correlated this with the occurrence of cardiovascular disease (CVD).
Published in The American Journal of Medicine, the findings revealed that individuals with the highest consumption of UPFs faced a 47% higher risk of experiencing a heart attack or stroke compared to those who consumed the least, even when controlling for various confounding factors. The researchers stress that decreasing UPF consumption is an urgent public health issue, drawing parallels to past initiatives to reduce tobacco use. They advocate for enhancing access to affordable, nutritious foods to help prevent CVD.
Charles H. Hennekens, M.D., FACPM, FACC, the senior author and First Sir Richard Doll Professor of Medicine and Preventive Medicine, highlighted the significant implications of the findings for future research, clinical practices, and public policy. They noted that the results suggest a need for increased focus on the health impacts of ultra-processed foods.
