Abstract

Objective:This study aimed to evaluate the association between low fruit and vegetable consumption and colorectal polyps. Methods:A retrospective study was conducted among 1,228 participants aged 50-65 years who completed 2-time colonoscopy exams at the first and the fifth year of a colorectal screening program. Consuming less than one serving of fruit and vegetable daily was rated as low. Colorectal polyps from colonoscopy findings were recognized in 3 types: hyperplastic, low risk and high risk adenomatous polyps. Results:The findings demonstrated high prevalence of low fruit (93.6%) and low vegetable (85.8%) consumption. Exercising individuals were more likely to consume both fruit (OR 2.28, 95%CI 1.42-3.65) and vegetable (OR 1.40, 95%CI 1.00-1.96), while smoking history individuals tended to consume vegetable (OR 2.08, 95%CI 1.22-3.55). Low fruit consumption was strongly associated with high risk adenomatous polyps (OR 4.39, 95%CI 2.40-8.03), while low vegetable consumption was distinctively associated with low risk (OR 6.26, 95%CI 4.11-9.55) and high risk adenomatous polyps (OR 8.64, 95%CI 5.30-14.09). Conclusion:This study provides additional evidence of the association between low fruit and vegetable consumption and colorectal polyps. Enhancing people fiber eating behavior may help preventing colorectal cancer risk.

Highlights

Minerals and fiber in fruit and vegetables have been scientifically proved as significant components of a healthy diet (Wallace et al, 2019)

Summary

Introduction

Minerals and fiber in fruit and vegetables have been scientifically proved as significant components of a healthy diet (Wallace et al, 2019). Low fruit and vegetable consumption has been linked to NCDs and leads to premature death (Wang et al, 2014; Aune et al, 2017), as well as colorectal cancer risk (Vogtmann et al, 2013; Aoyama et al, 2014: Ben et al, 2015). Colorectal polyps can be histologically classified as non-neoplastic and neoplastic tumors (Shussman and Wexner, 2014). Non-neoplastic polyps include hyperplastic, inflammatory and hamartomatous types. Neoplastic polyps include adenomas and serrated types. While non-neoplastic polyps typically do not turn to cancer, neoplastic polyps increase the risk of cancer. A study has proved that people with hyperplastic polyposis (multiple lesions) had a high risk of colorectal cancer (Hyman et al, 2004)
