Is it true that a vegan diet improves blood sugar control in people with type 2 diabetes?
Yes. A systematic review and a meta-analysis of randomized trials report that vegan or vegetarian diets lower HbA1c and improve glycemic control in adults with type 2 diabetes, and a clinical review reaches the same conclusion. Individual randomized trials in the United States and Korea point the same way, though one systematic review finds the evidence insufficient to call any single diet superior.
