| Sumario: | Purpose: Consumption of ultra-processed foods (UPF) has been associated with increased risks of various age-related diseases. However, the potential association between UPF consumption and age-related eye diseases (AREDs) remains unclear. We aim to assess the associations between consumption of UPF and risk of AREDs including age-related macular degeneration (AMD), cataract and glaucoma. Methods: We included 156,232 individuals aged 50 or older, who were free from AREDs from UK biobank study. Dietary intake data were collected using 24-h dietary assessments. UPF is defined according to the NOVA classification, and all participants are divided into four quartiles based on the weight proportion (%) of UPF. During a median of 10 years of follow-up. Cox proportional hazards were used to estimate the association between the proportion of UPF in the diet and the subsequent risk of various AREDs. Results: After adjusting for multiple variables, individuals in the highest quartiles for UPF consumption exhibited an increased risk of AMD (hazard ratio (HR): 1.28; 95% confidence interval (CI): 1.01–1.63; p = 0.03), cataract (HR: 1.10; 95% CI: 1.01–1.20; p = 0.04), and glaucoma (HR: 1.27; 95% CI: 0.98–1.63; p = 0.06) compared to those in the lowest quartiles. Moreover, a 10% increase in the weight of UPF in diet was associated with an 8% higher risk of AMD (HR: 1.08; 95% CI: 1.01–1.15; p = 0.03), a 3% higher risk of cataract (HR: 1.03; 95% CI: 1.00–1.06; p = 0.04), and a 7% higher risk of glaucoma (HR: 1.07; 95% CI: 1.00–1.15; p = 0.05). Conclusion: Our results suggest that a higher proportion of UPF in the diet was significantly link with an elevated risk of AMD and cataract. While additional research is necessary to validate these findings in diverse populations and settings, these results offer initial evidence to endorse public health initiatives that encourage limiting consumption of UPF.
