#10: Processed meat
Almost any processing of meat before or during cooking can make it more dangerous. Products like bacon, hot dogs, deli meats, and sausage are loaded with huge amounts of salt plus cancer-causing chemicals like nitrate and nitrite. All that junk makes the product look better and last longer, but does no favors for your body.
Unfortunately, even meats that are naturally smoked still take on tar during processing, which is just as bad for you in food as it is in cigarettes. Incidentally, studies have shown that eating red meat every day increases the lifetime risk of cancer by 22%.
Instead – Buy from your local butcher; they tend to offer fresher, less processed meats and are happy to answer questions about their products. From the grocery store, choose organic meats and other products labeled as free of nitrate and nitrite.
