In research published in a June 2017 study by Texas University, it identified, “several natural compounds found in food, including turmeric, apple peels and red grapes, as key ingredients that could thwart the growth of prostate cancer, the most common cancer afflicting U.S. men.”
“The researchers found that … the most promising active ingredients were ursolic acid, a waxy natural chemical found in apple peels and rosemary; curcumin, the bright yellow plant compound in turmeric; and resveratrol, a natural compound common to red grapes or berries.”
