Red and Processed Meats Cause Cancer

Red and processed meat products are linked to cancer, according to a report from the World Health Organization published today in Lancet Oncology. Researchers from around the world examined more than 800 studies looking at the cancer-causing properties of red and processed meats. The authors highlighted a meta-analysis that found a 17 percent increase in risk for colon cancer per 100 grams of red meat consumed and an 18 percent increase risk with 50 grams of processed meat consumed, and ultimately concluded that they are “probably carcinogenic to humans” and “carcinogenic to humans,” respectively. Researchers also observed associations between red and processed meat products and stomach, pancreatic, and prostate cancers. Processing and other cooking methods for meat, including curing, pan-frying, and smoking, produce various carcinogenic chemicals.
