Can dietary fiber really work on colorectal cancer prevention? This is a question that has been puzzling scientists for decades. Findings from most experimental studies have shown protective effects of dietary fiber against colorectal cancer or colorectal adenomas, the benign colorectal polyps that have the potential to develop into colorectal cancer, whereas contradicting results have been demonstrated in epidemiological studies in which many case-control studies showed an inverse relationship between intake of fiberrich foods and risk of colorectal cancer, but inconsistent results by cohort studies and interventional studies were reported. The authors will make some comments on these controversial issues. In addition, we will also discuss the potential of using alternative dietary assessment methods for studies of dietary fiber and its relationship with colorectal cancer.
