    Objective: This study provides a comprehensive review of evidence regarding the consumption of processed meat and its association with various health outcomes based on existing systematic reviews and meta-analyses.Methods: A systematic search was conducted in PubMed, Embase, and Web of Science databases for systematic reviews and meta-analyses examining the relationship between processed meat consumption and health outcomes from the inception of each database until May 2023. A total of 33 articles and 54 meta-analyses were included in the review.Results: Consumption of processed meat was found to be associated with higher risks of various cancers, cardiovascular diseases, metabolic disorders, and all-cause mortality. Dose-response analysis revealed that an increase in processed meat consumption of 50g/day was associated with a 72% higher risk of gastric cancer, 17% higher risk of colorectal cancer, 4% higher risk of prostate cancer, and an 8% higher risk of chronic obstructive pulmonary disease (COPD). Conclusion: The consumption of processed meat poses greater health risks than benefits, and efforts should be made to reduce its intake.
