Ultra-processed food, genetic risk, and the risk of cardiometabolic diseases and cardiometabolic multimorbidity: A prospective study
Jing Wang Nutrition, Metabolism and Cardiovascular Diseases Volume 34, Issue 12, December 2024, Pages 2799-2806
Highlights
• Higher UPF consumption was associated with a higher risk of T2D, CVD, and CMM.
• High UPF consumption and high T2D-PRS were associated with a higher risk of T2D.
• Limiting UPF consumption is essential for primary and secondary prevention of CMDs.
Background and aims
This study aims to evaluate the impact of ultra-processed food (UPF) on type 2 diabetes (T2D), cardiovascular disease (CVD), hypertension, and cardiometabolic multimorbidity (CMM), and to explore the role of genetic susceptibility in these associations.
Methods and results
90 631 participants from the UK Biobank were included (collected between 2006 and 2010). The outcomes assessed included T2D, CVD, hypertension and CMM. The Cox proportional hazards model was used to evaluate their associations and the potential modification by genetic risk, which was estimated using the polygenic risk score (PRS). Participants with high UPF consumption had a higher risk of T2D, CVD, and CMM, with the adjusted hazard ratio (HR) of 1.36 (95 % confidence interval [CI]: 1.15, 1.61), 1.13 (95%CI: 1.03, 1.23), and 1.14 (95%CI: 1.05, 1.24), respectively. Those with high UPF consumption and high PRS for T2D, CVD, and hypertension had the highest risk of T2D (HR: 4.01; 95%CI: 2.83, 5.69), CVD (HR: 2.18; 95%CI: 1.86, 2.56), and hypertension (HR: 1.79; 95%CI: 1.61, 1.99), respectively. In participants with one cardiometabolic disease (CMD), those with high UPF consumption and high PRST2D or PRSCVD had the highest risk of developing CMM. A significant additive interaction was observed between PRST2D and UPF consumption on the risk of T2D.
Conclusion
Our study underscored the importance of identifying individuals with high UPF consumption for targeted dietary interventions to mitigate the risk of CMDs and CMM, particularly among those with a high genetic risk of CMDs.
