Dietary Patterns Systematic Reviews

Systematic Review Question

Are prevailing patterns of diet behavior in a population related to risk of type 2 diabetes?

Conclusion Statement

Limited and inconsistent evidence from epidemiological studies indicates that in adults, dietary patterns derived using factor or cluster analysis, characterized by vegetables, fruits, and low-fat dairy products tend to have an association with decreased risk of type 2 diabetes, and those patterns characterized by red meat, sugar-sweetened foods and drinks, French fries, refined grains, and high-fat dairy products tended to show an increased association for risk of type 2 diabetes. Among studies, there was substantial variation in food group components and not all studies with similar patterns showed significant association.
