According to a recent meta-analysis of observational studies, a high intake of soy, compared to a low intake, was associated with a 13% lower risk of developing T2D.iii However there are inconsistent findings among these types of studies. Some studies show benefits, while others find no advantages. A few reasons for these discrepancies have been proposed such as differences in quantities of soy consumed among the different population groups (low intake in US cohorts versus Asian cohorts). At this point, while there is some evidence suggesting soyfood intake is protective against T2D, the data is too mixed to reach firm conclusions.
