Plant-based dietary patterns were linked to lower colorectal cancer incidence
Prospective observational studies linked plant-based eating patterns with lower colorectal cancer incidence, including patterns emphasizing healthier plant foods. The analysis cannot establish causation.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Adults whose diets aligned more closely with plant-based patterns had lower colorectal cancer incidence in this observational synthesis. Analyses emphasizing healthier plant foods also showed an association. Because the underlying studies observed dietary patterns, the results cannot establish that changing diet caused the difference or specify an individual's expected benefit.
The abstract does not describe dietary reference categories, follow-up lengths or adjustment for other risk factors. Moderate variation between study results also limits this abstract-based interpretation.
What researchers found
Colorectal cancer incidence
For the dietary-adherence comparisons studied, the estimated diagnosis rate at a given time was 0.91 times the comparison rate. Exact reference categories and follow-up lengths are unspecified; this does not give an absolute risk difference.
Food quality was also examined
The review examined patterns emphasizing fruits, vegetables, whole grains, legumes and nuts. These patterns also showed an association, but the abstract does not establish that they outperform other plant-based definitions.
What the outcome captures
The outcome was colorectal cancer incidence. The reported hazard ratio does not provide an absolute difference in diagnoses between dietary groups over a specified period of follow-up.
