A study done at the Department of Biochemistry of Annamalai University in India shows that a compound derived from curcumins, a substance that makes curry yellow, may have both antioxidant and antidiabetic effects in type 2 diabetic rats.

In diabetic patients, increased production of reactive oxygen species (ROS) and lipid peroxidation may contribute to vascular complications. In this study, the researchers investigated the effect of tetrahydrocurcumin (THC) on the occurrence of oxidative stress in the brain of rats during diabetes.
