Deli meats, such as ham, salami, and bologna, are popular lunchtime favorites, but they can be deadly if eaten in large quantities. Processed deli meats contain preservatives, nitrates, and other chemicals that can increase your risk of heart disease and stroke. They also contain high levels of sodium, which can lead to hypertension and a buildup of fluid in the body. Eating too much deli meat can also increase your risk of certain cancers, such as stomach cancer, and even behavioral problems and learning difficulties in children.
Choose deli meats from your local butcher instead of those from supermarkets. You can also learn to avoid them.
