2015 Dietary Guidelines Advisory Committee Systematic Reviews

Systematic Review Question

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

Conclusion Statement

Limited evidence from a small number of studies suggests a lower risk of lung cancer associated with dietary patterns containing more frequent servings of vegetables, fruits, seafood, grains and cereals, legumes and lean vs. higher fat meats and lower fat or non-fat dairy products. Despite reported modest significant reductions in risk, definitive conclusions cannot be established at this time because of the small number of articles, as well as wide variation in study design, dietary assessment and case ascertainment.
