Soy Not Effective on Glycemic Control

Mar 15, 2011

Previous studies have suggested that soy intake may carry beneficial effects on glycemic control, but human intervention studies have yielded mixed results. A recent meta-analysis of 24 trials and more than 1,500 subjects found that soy consumption does not significantly affect measures of glycemic control. Researchers noted that there was a favorable change in fasting glucose concentrations in studies that used whole soy foods or a soy diet in the subgroup analysis. There were not enough trials to generate sufficient evidence for other glycemic variables, such as HbA1c and two-hour postchallenge glucose and insulin concentrations.
