Processed meats
Almost all traditional breakfast meats, including bacon, sausage, and ham, are heavily processed. These are high in salt, which may raise blood pressure in salt-sensitive people. They also include nitrites, which may increase your risk of some diseases such as stomach cancer. However, further study is required to completely understand how processed meat consumption influences cancer risk.
In any case, reducing your consumption may help lessen your risk. Instead, use seasoned ground pork to make a simple, healthier sausage substitute.
