Prophylactic Properties of Carrot Juice in Patients With High-Risk Colorectal Polyps

Summary

The goal of this prospective randomized double-blinded bi-national study is to test the prophylactic effect of polyacetylenes from carrots on the population of patients who had a resection of high-risk adenomas of the large bowel. The main question it aims to answer is: Will carrot juice rich in polyacetylenes inhibit neoplastic transformation and growth in high-risk humans? Participants will have to drink 100 ml of juice daily after the adenoma resection for 1 year and keep a simple diary/calendar. Researchers will compare the group with ingestion of Falcarinol (FaOH) / Falcarindiol (FaDOH) rich carrot juice versus the group consuming placebo juice, to see if the polyacetylenes significantly reduces neoplastic transformation and growth in high-risk patients.
