2015 Dietary Guidelines Advisory Committee Systematic Reviews

Systematic Review Question

What is the relationship between dietary patterns and risk of colorectal cancer?

Conclusion Statement

Moderate evidence indicates an inverse association between dietary patterns that are higher in vegetables, fruits, legumes, whole grains, lean meats and seafood, low-fat dairy and moderate alcohol; and low in red and processed meats, saturated fat and sodas and sweets relative to other dietary patterns and the risk of colon and rectal cancer. Conversely, diets that are higher in red and processed meats, French fries and potatoes, and sources of sugars (i.e., sodas, sweets and dessert foods) are associated with a greater colon and rectal cancer risk.

2015 DGAC Grade: Moderate
