The World Health Organization recently added a new item to the list of known carcinogens: hot dogs. Well, not specifically hot dogs, but processed meat in general. This is based on a report by the agency\u2019s cancer research arm.\nThis news has garnered many headlines and a good bit of confusion. The WHO classification means that there\u2019s sufficient evidence that eating processed meat causes cancer, namely specifically colorectal cancer.\nWhat Is Processed Meat?\nProcessed meat is meat that has been altered to make it last longer. This is done by curing, salting, fermenting, or other processes. These meats include:\n\nHam\nBacon\nHot dogs\nSausage\nCorned beef\nBeef jerky\nSome canned meats and others\n\nWhat Does the WHO Classification Mean?\nThe WHO now classifies processed meat as Group 1, putting it in the same class of carcinogens as:\n\nAlcohol\nTobacco\nAsbestos\n\nAll Group 1 means is that this thing is known to cause cancer. There\u2019s no ranking of danger within that classification.\nSo, this classification doesn\u2019t mean that hot dogs are as dangerous as cigarettes. The report estimates that 34,000 deaths per year worldwide could be caused by a diet high in processed meat.\nHow Do These Meats Cause Cancer?\nThe link between processed meat and cancer isn\u2019t new. Many of you may remember headlines in the 1970s with a similar story.\nBack then, the talk focused on nitrates and nitrites, which often come from sodium nitrate added to processed meat to preserve it and give it that pink color. You can find many deli meats, sausages, bacon, and hot dogs on the shelf now that say \u201cno nitrates or nitrites added.\u201d\nHowever, nitrates and nitrites still occur naturally with common alternatives like sea salt or celery juice. Research hasn\u2019t been able to strongly link these chemicals to cancer. The WHO report mentioned N-nitroso compounds as a possible culprit, but the experts say it\u2019s still not well understood why these foods cause cancer.\nHow much processed meat is too much?\nBased on research, the report doesn\u2019t recommend that everyone stop eating bacon right away. The research group concluded that for every 50 grams of processed meat you eat daily, your risk of colorectal cancer goes up by 18 percent.\nThat amounts to about one sausage, just under two slices of bacon, and approximately one hot dog, depending on the brand.\nBesides the cancer risk, you can find many reasons to eat processed meats in moderation. They usually contain high amounts of fat, cholesterol, and sodium, which all contribute to heart disease. To keep yourself healthy, be sure to keep your diet well balanced.\nDo not despair with all this information.
