Key clinical point: Individuals with the highest vs. lowest intake of nuts and legumes had a 16% and 10% lower risk for colorectal cancer (CRC), respectively.
Major finding: The pooled relative risk (RR) for CRC among individuals with the highest vs. lowest consumption of nuts and legumes was 0.84 (95% CI 0.71-0.99) and 0.90 (95% CI 0.83-0.98), respectively. A once-daily consumption of 28 g nuts and 100 g legumes was associated with a 33% (RR 0.67; 95% CI 0.45-0.98) and 21% (RR 0.79; 95% CI 0.64-0.97) lower risk for CRC, respectively.
Study details: Findings are from a meta-analysis of 13 and 29 studies that evaluated the association of the consumption of nuts and legumes with CRC risk, respectively.
Disclosures: The study was supported by the National Research Foundation of Korea, Ministry of Science, ICT, and Future Planning. The authors declared no conflicts of interest.
