Title
Association Between Protein Diet Score And Colorectal Adenoma Risk: A Prospective Study
Summary
Colorectal cancer (CRC) is the third most common cancer worldwide(1). Most CRC develops through the adenoma-carcinoma sequence, leading developed countries to implement screening programs for colorectal adenomas that have effectively reduced CRC incidence and mortality(2). Beyond screening, identifying modifiable risk factors, particularly dietary factors, is crucial for primary prevention.
Studies have shown that various nutrients influence colorectal adenoma risk. While protein's role in intestinal health has been suggested, evidence linking protein intake to colorectal adenoma risk remains limited(3). Additionally, recent dietary guidelines emphasize increasing plant-based protein consumption, as proteins from different sources may affect intestinal health differently(4).
To investigate this relationship between protein and colorectal adenoma, we analyzed data from the PLCO Screening Trial, using the Protein Diet Score to comprehensively evaluate both the quantity and quality of protein intake.
