Dietary Patterns Systematic Reviews

Systematic Review Question

Are prevailing patterns of diet behavior in a population, assessed using factor or cluster analysis, related to body weight or risk of obesity?

Conclusion Statement

Limited and inconsistent evidence from epidemiological studies examining dietary patterns derived using factor or cluster analysis in adults found that consumption of a dietary pattern characterized by vegetables, fruits, whole grains, and reduced-fat dairy products tends to be associated with more favorable body weight status over time than consumption of a dietary pattern dominated by red meat, processed meats, sugar-sweetened foods and drinks, and refined grains.
