The curcumin compound in turmeric, a main ingredient in curry, shows promising cancer-fighting abilities in lab studies. A “cooling” spice, turmeric has anti-inflammatory properties that help thwart tumor growth and block biological pathways needed for melanoma and other cancers to flourish. In 2007, Chinese scientists found curcumin helps tamp down hormones needed for prostate cancer to take root in the body.
Use It: Pair turmeric with black pepper to seriously amplify its effects. Indian scientists found that adding the black pepper compound piperine to curcumin increased its bioavailability in humans by 2,000 percent.
