Abstract

The 2005 Dietary Guidelines for Americans include quantitative recommendations for 2 eating patterns, the USDA Food Guide and the Dietary Approaches to Stop Hypertension (DASH) Eating Plan, to promote optimal health and reduce disease risk. A Mediterranean dietary pattern has also been promoted for health benefits. Our objective was to determine whether adherence to the USDA Food Guide recommendations, the DASH Eating Plan, or a Mediterranean dietary pattern is associated with reduced risk of distal colorectal adenoma. In the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial, men and women aged 55-74 y were screened for colorectal cancer by sigmoidoscopy at 10 centers in the U.S. After adjusting for potential confounders, men who most complied with the USDA Food Guide recommendations had a 26% reduced risk of colorectal adenoma compared with men who least complied with the recommendations (OR USDA score >or= 5 vs. or= 5 vs. or= 5 vs.
