Oncologist Dr. Ted A. James has issued warnings regarding the potential cancer risks associated with specific food additives, particularly sodium nitrate and sodium nitrite. These preservatives are frequently used in processed meats—including bacon, ham, sausages, and deli meats—to maintain color, flavor, and shelf life.

Dr. James advises consumers to look past marketing claims on the front of packaging, such as ‘healthy’ or ‘high in protein’, and instead scrutinize the ingredient lists on the back. He notes that nitrites can react during digestion or food preparation to form nitrosamines, compounds that may damage DNA and cells. This process is linked to an increased risk of certain cancers, specifically colorectal and rectal cancer.
