Higher intake of preserved vegetables and colorectal polyps: What is the link?

Key clinical point: Higher consumption of preserved vegetables was associated with an increased prevalence of colorectal polyps as a precursor lesion of colorectal cancer (CRC), particularly small polyps in a population at high risk for CRC.

Major finding: Consumption of preserved vegetables was associated with an 18% higher prevalence of colorectal polyps (adjusted odds ratio highest vs lowest quartile [aOR_{Q4 vs Q1}], 1.18; P trend = .02) and 17% higher prevalence of small polyps (aOR_{Q4 vs Q1}, 1.17; P trend = .03).

Study details: Findings are from a survey analysis of 6,783 respondents from Lanxi Pre-colorectal Cancer Cohort who were at high risk for CRC.
