For years there has been a controversy whether grilled meats cause cancer . A few research studies have found that grilling and broiling cause meats (red meat, poultry and fish included ) to produce cancer-causing compounds. These compounds known as HCAs (heterocyclic amines), have been shown to cause tumors in animals and possibly increase the risk of cancers of the breast, colon, stomach and prostate in humans.This was confirmed officially by The National Institute of Health, Dept. of Health and Human Services in January 2005 when it added heterocyclic amines in it’s hit list of cancer causing agents.
