Type 2 diabetes is less likely to occur in individuals who followed a plant-based diet rich in fruits, vegetables, legumes, and whole grains.

​This study assessed the risk of type 2 diabetes associated with the consumption of plant-based diets. Researchers conducted a meticulous meta-analysis on data extracted from 9 studies. 

Researchers observed that strict adherence to plant-based dietary patterns characterized by high intake of fruits, vegetables, legumes, and whole grains diminished the risk of type 2 diabetes. This study concluded that "plant-based dietary patterns, especially when they are enriched with healthful plant-based foods, may be beneficial for the primary prevention of type 2 diabetes."
