A team of Korean researchers from Busan University and Cha University have developed what they call cpKimchi — or kimchi that has cancer-preventative properties according to Korea Bizwire.

The study was led by doctors Ham Gi-baeg and Park Gun-young, both of whom will present the study at the 2015 CRI (Seoul National Cancer Research Institute).

The experiment was performed over the course of 36 weeks on a group of lab rats that had gastric tumors. The control group experienced an increase in gastric ulcers, gastric tumors in addition to Helicobacter infections. The health of those that were fed cpKimchi improved significantly, while the third group that was fed normal kimchi experienced the same issues as the control group.

Researchers have chosen not to reveal the formula to their cpKimchi until their patents have been approved.
