According to a new study published in the journal Nutrition and Cancer, adherence to the Dietary Approaches to Stop Hypertension (DASH) diet may reduce the risk for colorectal cancer.        

Researchers performed a meta-analysis of six observational studies (four prospective cohorts and two case-control) identified through a literature search on MEDLINE and ScienceDirect. The risk estimates for colon cancer were determined as per the adherence levels to the DASH diet.

The pooled relative risk [RR] of colorectal cancer for the highest vs lowest DASH score was 0.81 (95% CI, 0.75-0.88; I2=54.0%; P=.017). Adherence to the DASH diet was also associated with lower individual risks for colon cancer (RR, 0.88; 95% CI, 0.78-0.99; I2=52.6%; P=.039) and rectal cancer (RR, 0.73; 95% CI, 0.64-0.83; I2=12.2%; P=.335).

The authors said, "these findings support the need to promote healthy dietary patterns with higher intake of whole grain, vegetables, fruits, and low-fat dairy products and lower intake of salt, sweets and saturated fat to reduce the risk of colorectal cancer."
