Normally, sodium nitrate in vegetables does not pose the same health risk as nitrites found in processed meat. The nitrites added to processed meats as preservatives and color enhancers can combine with proteins called amines to form compounds called nitrosamines.itrosamines have shown cancer-causing potential in animal studies. Nitrates and nitrites themselves do not have cancer-causing potential. Vegetables contain ascorbic acid, a form of vitamin C and an antioxidant which helps prevent nitrosamine formation, although it might not completely prevent it.
