Understanding Sugar-Sweetened Beverages (SSB) and Colorectal Cancer (CRC)

This study will recruit and consent approximately 120 subjects in the baseline study until the follow-up study recruitment goals of 20 subjects is met. This pilot proposal to: Aim 1) assess the feasibility of conducting a randomized controlled trial of iSIPsmarter among high-risk patients with newly detected large colorectal adenoma to reduce Sugar-Sweetened Beverages (SSB) consumption, and Aim 2) examine the investigators' central hypothesis that SSBs contribute to racial disparities in the development of side-specific colon neoplasia via differentially impacting epigenetic aging and methylation of right vs. left normal colon tissues of African-Americans (AA) vs European-Americans (EA). In order to do so, the investigators will first conduct a study to collect baseline information from eligible and interested participants. Behavioral, lifestyle, and genetic information will be collected from participants undergoing a colonoscopy with large polypectomy removal to set up a biobank. The participants enrolled in this study will then be screened for their interest and eligibility in participating in the follow-up study, a randomized iSIPsmarter intervention trial. The investigators will enroll 20 patients in the follow-up study (1:1 ratio intervention vs. control; equal number of AAs and EAs) with newly detected/resected large colorectal adenomas to collect normal colon tissue biopsies pre- and post-iSIPsmarter intervention and test the investigators' hypotheses.
