Anti-inflammatory therapeutic approaches are considered to be important in management of type 2 diabetes and prevention of its complication. This trial was conducted to evaluate the effects of broccoli sprouts powder (BSP) with high sulforaphane concentration, on inflammatory markers. Eighty-one patients with type 2 diabetes were randomly assigned to three treatment groups for 4weeks. The groups received either 10g/d BSP (n=27), 5g/d BSP (n=29), or placebo (n=25). Serum high-sensitive C reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis α (TNF-α) were measured at baseline and 4weeks after treatment. Sixty-three patients were included in the analysis: 10g/d BSP (n=21), 5g/d (n=22), placebo (n=20). After 4weeks, in the BSP treatment groups there was a significant decrease in serum hs-CRP concentration (−20.5% and −16.4%), and also non-significant decrease in serum IL-6 (−3.6% and −0.7%), and TNF-α concentration (−1.6% and −10.9%), in group A and B, respectively. Serum hs-CRP and IL-6 were lower in group A as compared to the controls after intervention. High-sulforaphane BSP had favorable effects on inflammatory markers in type 2 diabetic patients.
