A recent study examining data from the UK Biobank has found a significant association between the consumption of ultra-processed foods (UPFs) and the risk of developing atherosclerosis, a major contributor to cardiovascular disease. The study involved 133,797 participants who were free from atherosclerosis at the start of the research.

The researchers assessed dietary intake using 24-hour recalls and identified UPFs based on the NOVA classification system. Over a median follow-up period of nearly 11 years, 654 new cases of atherosclerosis were recorded. The results showed that participants in the highest quartile of UPF consumption had a 40% higher risk of atherosclerosis compared to those in the lowest quartile. Specifically, for servings per day, the hazard ratio was 1.40 (95% CI 1.12–1.75), and for grams per day, the hazard ratio was 1.29 (95% CI 1.03–1.60).
These findings suggest that higher intake of UPFs correlates with an increased risk of atherosclerosis, highlighting the need for further exploration into metabolic and proteomic signatures related to UPF consumption. The study also performed analyses that linked consumption patterns with signs of systemic inflammation and lipid metabolism dysregulation.
The implications of this research motivate recommendations to reduce UPF intake and promote diets based on whole foods. This dietary shift could contribute significantly to cardiovascular disease prevention.
The study underscores the importance of understanding dietary patterns in relation to health, particularly given the increasing prevalence of UPFs in Western diets, which can constitute a large portion of daily caloric intake. Public health policies aimed at reducing UPF consumption and encouraging healthier food environments may be essential in addressing the growing burden of atherosclerotic cardiovascular disease.
