World Health Organization experts recently reported that eating processed meat can cause cancer. Processed meat is meat that has been preserved by curing, salting, smoking, drying or canning. Experts from the WHO’s International Agency for Research on Cancer in Lyon, France, studied 800 cases. IARC researchers linked processed meat, such as hot dogs and ham, to bowel cancer, as well as pancreatic cancer and prostate cancer. The IARC has placed processed meat in the same category that it placed tobacco, asbestos, and diesel fumes. WHO experts also called red meat, including beef, lamb and pork, “probably” carcinogenic to humans. Dr. Kurt Straif is with the IARC. He said that the risk of cancer increases with the amount of meat a person eats. Dr. Straif said eating 50 grams of processed meat per day increases a person’s risk of bowel cancer by 18 percent. Health experts in some countries already advise against eating large amounts of red and processed meat. But those advisories have centered on the increased risks of heart disease and obesity, not cancer. Meat industry groups are protesting the WHO study. They say meat is part of a balanced diet. They also argue that the causes of cancer are broad, and include environmental and lifestyle factors. The WHO report cited the Global Burden of Disease project estimates that diets high in processed meat lead to 34,000 cancer deaths per year worldwide.
