Dietary Patterns Systematic Reviews

Systematic Review Question

What is the relationship between adherence to dietary guidelines/recommendations or specific dietary patterns (assessed using methods other than index/score, cluster or factor, or reduced rank regression analyses) and risk of type 2 diabetes?

Conclusion Statement

There is insufficient evidence on a relationship between adherence to a Mediterranean-style or vegetarian diet pattern and incidence of type 2 diabetes. There is limited, inconsistent evidence that adherence to a Mediterranean-style, DASH or modified DASH, or Nordic dietary pattern results in improved glucose tolerance and insulin resistance.

Grade: IV - Grade Not Assignable - Incidence of type 2 diabetes

Grade: III - Limited - Glucose tolerance and insulin resistance
