Turmeric Component Reduces Type 2 Diabetes Incidence

Curcumin reduces the incidence of type 2 diabetes and improves beta-cell function in adults with prediabetes, according to a published study. Somlak Chuengsamarn, M.D., from Srinakharinwirot University in Nakornnayok, Thailand, and colleagues randomly assigned 240 adults with prediabetes to receive oral curcumin or placebo twice a day for nine months. Type 2 diabetes progression was assessed following treatment.

After nine months the researchers found that 16.4 percent of the placebo group and none of the curcumin group were diagnosed with type 2 diabetes mellitus. Curcumin treatment was associated with significantly improved beta-cell function, with higher homeostasis model assessment- beta and lower C-peptide levels. Compared with the placebo group, curcumin treatment was also associated with lower homeostasis model assessment-insulin resistance and higher adiponectin.

"A nine-month curcumin intervention of a prediabetes population significantly lowered the number of prediabetic individuals who eventually developed type 2 diabetes mellitus," Chuengsamarn and colleagues conclude. "In addition, the curcumin treatment appeared to improve overall function of beta-cells, with very minor adverse effects."
