Association Between Plant-Based Dietary Patterns and Risk of Type 2 Diabetes A Systematic Review and Meta-analysis

Key Points

Question: What is the role for plant-based dietary patterns in the primary prevention of type 2 diabetes among adults?

Findings: In this systematic review and meta-analysis of prospective observational studies assessing the association between plant-based dietary patterns and risk of type 2 diabetes among adults, higher adherence to plant-based dietary patterns was associated with a lower risk of type 2 diabetes; this association was strengthened when healthy plant-based foods, such as fruits, vegetables, whole grains, legumes, and nuts, were included in the pattern. Findings were broadly consistent in several prespecified subgroups and in sensitivity analyses.

Meaning: Greater adherence to plant-based dietary patterns, especially those rich in healthful plant-based foods, is associated with lower risk of type 2 diabetes.
